Chapter
2 – Affected Environment
General Setting and Access (pg S-11)
Precipitation
is 15 – 20 inches coming mostly in fall, winter, and spring.
Temperatures range from low 20s in winter to high 80s – 90s in
summer.
Recreation – White
Water Boating (pg S-12)
One
of the unique features of the Upper Klamath River is the extended season
for whitewater boating provided as a result of year-round releases from
J. C. Boyle Dam/Powerhouse system.
.
.The primary rafting season on the
Upper Klamath
River
extends from
Memorial day through Labor Day.
(pg S-13)
Since
the summer of 1998, PacificCorp has varied the water release schedule to
include more releases that start later in the day, starting the release
as late as
2-4 pm
.
This change in scheduling reflects changing market conditions for
wholesale electric power, as well as anticipated regional electric power
shortages during summer heat waves.
This
shift in water release start times has impacted whitewater boating
opportunities by either forcing boaters to launch their trips later in
the day, or to cancel or postpone their trips due to the timing of the
water release.
Fishing (pg S-13)
The
upper
Klamath River
within the
planning area is managed as a wild trout river in both Oregon
and California
.
The river provides an excellent trout fishery and is among one of
the better fly fishing rivers in Oregon.
Roads and Access (pg
S-13)
Public
access to the planning area is currently on the Topsy and J.C. Boyle
Powerhouse roads. These
roads provide the majority of access in the planning area.
Cultural
Resources/Traditional Use (pg S-13)
Cultural
resources within the planning area are divided into three categories (1)
prehistoric, (2) historic, and (3) current Native American traditional
use.
There
are about 100 known prehistoric sites in the
Upper Klamath
River
canyon.
There are fishing, gathering, and hunting camps, and pit house
villages (pit houses are circular depressions reflecting a
semi-subterranean prehistoric house structure).
The
area was home to a variety of cultural groups at different times,
including the Shasta nation of northern California, the Modoc and
Klamath Tribes of the Klamath Basin, the Takelma of the upper Rogue
River, and possibly the Pit River Indians of northeastern California.
Europeans
have used the upper
Klamath River
Canyon
extensively
since the 1850s, settling on terraces and flood plains along the river
and several meadow areas. There
are numerous historic ranches that have structures still standing that
were constructed between the late 1800’s and early 1900’s.
(pg
S-14) Today,
members of the Klamath Tribe and the Shasta Nation continue to use the
canyon for spiritual purposes, hunting, fishing, gathering, and other
cultural activities. Many
of the traditional use areas can be considered traditional cultural
properties.
Watershed
Values (pg S-16)
Beneficial Uses
Among
those roles are “beneficial uses,” as determined by Oregon
Department of Environmental Quality.
Established beneficial uses for the upper Klamath River in Oregon
include public and private domestic water supply; industrial water
supply; irrigation; livestock watering; salmonid rearing and spawning;
resident fish and aquatic life; wildlife and hunting; fishing; boating,
and water contract recreation; and aesthetic quality.
Energy Generation and
Transmission
The
planning area includes the portion of the
Klamath River
between two
hydroelectric facilities: J.C. Boyle Dam in
Oregon and
Copco 1 Reservoir in
California
.
The J.C. Boyle Dam 88-megawatt power generation plant is 4.3
river miles below the dam. This
facility has turbine generators that supply power during high use (peak)
periods.
Water Rights
Water
use in the
Klamath
River Basin
upstream from,
and within, the planning area affects streamflows in the
Klamath River
.
An adjudication process now being conducted by the Oregon Water
Resources Department (OWRD) will determine surface water rights
associated with the designated wild and scenic river.
This process will establish water right claims submitted by BLM.
Klamath
River
Instream
Flows
Within
Segments 1 and 2, PacificCorp is licensed to divert up to 2,500 cfs of
Klamath River
water to
generate hydroelectric power. The
utility also has two permits that allow a small diversion from the dam
for irrigation, stock and domestic use.
The
BLM has filed a claim for instream flows in Segment 2 of the planning
area based on the Wild and Scenic
Rivers Act of 1968. In
the Act, Congress expressly reserved water for flow-dependent
outstandingly remarkable values. Flows
were claimed (Federal Reserve Claim 376, 1999) for three outstandingly
remarkable values: fisheries
(625 cfs from April 1 through June 15, and 525 cfs for the rest of the
year) and recreation (whitewater rafting, 1,500 cfs between Memorial Day
and September 30). The BLM
water right claim on the River is pending in the Klamath Basin
Adjudication.
Other Water Rights
Other
entities also have water claims and/or rights on the
Klamath River
, including
the Oregon Department of Parks and Recreation, the Bureau of Indian
Affairs (on behalf of the Klamath Tribes), the Oregon Department of
Forestry, and private landowners. The
Klamath River Basin Compact also provides guidance, along with other
applicable laws, for water rights administration in the
Klamath
Basin
(see River
Plan for further details).
Streamflows (pg S-17)
The
upstream end of the
Klamath River
drainage
encompasses about 4,080 square miles of surrounding land.
Snowmelt in this drainage area flows mostly to
Upper Klamath
Lake
, which
creates late winter and spring naturally occurring peak flows to the
Klamath River
.
Summer
flows come from the Link River Dam (on
Upper Klamath
lake
), and
groundwater discharges. Elevated
flows in fall are caused by return flow from irrigated areas south and
west of
Klamath Falls
.
The
other primary cause of streamflow variance is the operation of the J.C.
Boyle hydroelectric facilities. Flow
varies according to water availability, instream flow requirements for
salmon (listed under the Endangered Species Act) downstream from Iron
Gate Dam, and PacificCorp’s FERC license.
Flows
in Segment 1 are not subject to the daily fluctuations that occur in
Segments 2 and 3 from powerhouse operations.
Energy
demand (and subsequent hydroelectric plant use) can determine the amount
of flow in the river. When
daily average natural river flows are less than around 3,300 cfs, the
facility can increase flow to produce power during peak energy demand
period which is called “peaking”.
On days when the J.C. Boyle complex is operated for peaking
power, stage (change in river surface elevation)
can be raised or lowered about 2.2 feet over a 6-hour period.
Water Quality
Water
Quality, which as previously mentioned, is designated “water quality
limited” under terms of the Clean
Water Act, is affected by upstream point and nonpoint pollutant
sources in the area.
Some examples of characteristics that limit water quality in the
planning area are high algal content, high pH, temperature,
chlorophyll-a, and dissolved oxygen.
These may detrimentally affect beneficial uses and outstandingly
remarkable values (including fisheries, recreation, and wildlife).
Aquatic
Species/Habitat (pg S-17)
The
dams on the
Klamath River
have affected
fish species distribution throughout the
Klamath
Basin
.
Historically, the Klamath River
was a
passageway for anadromous fish, salmon, steelhead, and Pacific lamprey
as they migrated to various tributaries of the
Klamath River
and Upper
Klamath Lake
(ODFW 1997).
These fish runs were halted in 1910 by the construction of Copco
1 Dam, completed in 1917, which permanently blocked fish passage (City
of Klamath Falls 1986). Five
more dams were built on the upper Klamath River
; Copco II and
Iron Gate
are located in
California
, and Link
River, Keno,
and J.C. Boyle Dams are located in
Oregon
(PacificCorp
2000). J.C. Boyle, Keno,
and Link River Dams have fish ladders intended for trout migration, each
varying in function. Only
J.C. Boyle Dam has a screening facility to prevent entrainment of fish
into the power diversion canal.
(pg
S-18) The
hydroelectric project on the upper
Klamath River
will be
assessed for reintroduction of anadromous species through the
hydroelectric facilities as part of the Federal Energy Regulatory
Commission relicensing process.
The
upper
Klamath River
is inhabited
by 10 known native fish species. Three
species of note are: redband trout – the primary game fish in the
Klamath River
,
Lost
River
sucker –
(state and federally listed endangered species). and shortnose sucker
– (state and federally listed endangered species).
Other
native species are Klamath smallscale sucker, blue and tui chub, Klamath
specked dace, sculpin species, and lamprey species.
At
least fourteen exotic species occur in the river and reservoirs.
Yellow perch, fathead minnows, Sacramento
perch, and
golden shiner typically favor slower water habitats including slackwater
shoals close to Copco Reservoir, and generally are not found in swift
flowing portions of the river (USDI-BLM 1990).
Although not documented by fisheries specialists, there have been
at least two reports of white sturgeon in the planning area.
White sturgeon was planted in
Upper Klamath
Lake
in 1956 (ODFW
1997). Brown trout, planted
in Copco Reservoir, inhabit and migrate through the
California
reach to spawn
in Shovel Creek (DCFG 2000). Steelhead,
planted into Copco Reservoir 1971 – 1981 (excepting 1975, 1977, and
1978) has been reported from the
California
portion of the
Klamath in the past.
Range
Resources (pg S-18)
Cattle,
wildlife, and a small herd of wild horses currently compete for forage
in the planning area. U.S.
Timberlands, PacificCorp, and BLM-administered lands are used for
grazing in and around the planning area.
Hay production is also common on privately-owned (PacificCorp)
meadows in the planning area in
California
.
Two
BLM grazing allotments exist within the planning area; Edge Creek
Allotment (#0102) and Laubacher Lease Allotment (#0155), and grazing
occurs on private lands.
Wildfire
Management (pg S-19)
Lightning
occurrence in the
Klamath River
Canyon
caused 20
lightning ignitions from 1990 to 1999.
The fire return interval for the conifer forest/woodland type is
every 10 to 20 years. The
estimated fire return interval for oak woodlands in this type of canyon
terrain is 5 to 15 years.
Exclusion
of natural fire in the Klamath
Canyon
has resulted
in high fuel loading and created conditions where the potential for
wildfire occurrence is increased.
Socioeconomics
(pg S-19)
“The
major sources of income are agriculture, government, and tourism.”
Chapter
3 – Oregon Scenic Waterways Administrative Rules (pg S-21)
The
Oregon Scenic Waterways System was created by ballot initiative in 1970.
Scenic
waterway management plans (administrative rules) are developed to
protect or enhance the aesthetic and scenic values of scenic waterways,
while allowing compatible agriculture, forestry, and other land uses.
Existing Condition
The
Klamath River
from the J.C.
Boyle Powerhouse to the Oregon-California state line was designated a
scenic waterway in 1988. Ownership
within this corridor is 75 percent BLM, 23 percent private, and 2
percent State of Oregon
.
Klamath
County
has zoned the
private lands within the scenic waterway corridor as “forestry.”
To
date, uses in the canyon have been primarily recreation, range, and
timber management.
Chapter
1 – Introduction
Management Direction and Management Goals (pg 9)
Relationships and Implications Regarding
Klamath
Basin
Water
Issues (pg 13)
PacificCorp,
the owners of the Klamath Hydroelectric Project (
Big Bend
#2082) are
applying to the Federal Energy Regulatory Commission (FERC) for a new
license. The current
license was issued in 1956 for 50 years, and will expire in March of
2006. John C. Boyle Dam and
power plant are located within the proposed River planning area
boundary. The final river
Plan will identify resource impacts and mitigations regarding the
PacificCorp operations of their facilities to fish, recreation,
cultural, and wildlife resources. These
impacts (both negative and positive) need to be considered during the
FERC relicensing process. The
final River Plan is scheduled to be completed in 2004 before FERC begins
an Environmental Impact Statement (EIS) in 2004 on the relicensing of
the Klamath Hydroelectric Project #2082.
The final River Plan will contain important resource information
and provide a basis for alternative development for FERC’s EIS.
All
water issues (both quantity and quality) and fisheries (both inland and
anadromous fisheries) are controversial in the
Klamath
Basin.
Water and fishery proposed actions are addressed in the River
Plan and have no direct or indirect impacts that would influence the
Bureau of Reclamation’s Klamath River Anadromous Fish Restoration and
Operation Plan or the Environmental Protection Agency/State Total
Maximum Daily Load (TMDL) development process.
Chapter
1 – Introduction
The Planning Process (pg 18)
Identification of Issues (pg 20)
Wildlife and Fisheries (pg 22)
Wildlife:
There are threatened and endangered (bald eagle), and
special status species (western pond turtle, Townsend big-eared bat, and
white headed woodpecker, etc.) that use the river corridor.
Habitat for these species would be evaluated to determine the
type of management needed to protect or enhance the survival of these
species. This plan
addressed unique wildlife habitat, such as big game winter habitat and
oak woodlands. The impacts
from wildlife habitat enhancement projects to scenic values and impacts
to wildlife from other resource management practices would also be
addressed.
Fisheries:
Fisheries
is one of the outstandingly remarkable values that earned the
Klamath River
its
designation as a wild and scenic river.
Management concerns deal with the endangered
Lost
River
and shortnose
suckers and special status Klamath redband trout that use the river.
The
river has been designated as a wild trout fishery.
The planning area is also within the historic range of the
threatened and endangered coho salmon.
There are management concerns regarding the passage of both
resident fish and fish that enter the river to swim upstream and spawn.
There
are also recreational trout fishing concerns surrounding the lack of
large fish within the river.
There is evidence that the water peaking (repetitious high
flows), which optimize generation of power from J.C. Boyle Dam, impacts
the aquatic habitat for fisheries on the stretches analyzed under this
plan. There maybe
opportunities to improve fish habitat.
There is speculation that the variation in water flows (for power
generation), or the design of the hydropower project may affect the size
of fish.
Chapter
2 – Affected Environment
Description of Affected Resources and Facilities (pg 28)
Whitewater Boating (pg 29)
One
of the unique features of the upper
Klamath River
is the late
season whitewater boating opportunity provided as a result of year-round
releases from Boyle Dam/Powerhouse system.
At least one generator
must be operating to provide adequate flows for whitewater rafting.
Since
the summer of 1998, PacificCorp has varied the release schedule to
include more releases that start later in the day, staring the release
as late as
2-4 p.m.
This change scheduling reflects changing market conditions for
wholesale electric power, as well as anticipated regional electric power
shortages during summer heat waves.
(pg
30) Historically,
the Boyle Powerhouse was shut down for two weeks in July each year to
perform maintenance; however, in recent years this maintenance work has
been shifted to September to avoid the prime rafting season (BLM).
During winter and spring both generators operate, increasing the
flows to 2,500 cfs or higher.
(pg
31) “(from)
RM 214.3 to 209.3, the river drops 77 feet per mile.”
“(from) RM 209.3 to 204, (the river) drops 32 feet per
mile."
Cultural Resources and
Traditional Uses (pg 37)
Cultural
resources within the planning area are divided into three categories (1)
prehistoric, (2) historic, and (3) current Native American traditional
use. Prehistoric resources
are associated with Native Americans and date before the time of contact
with European settlers (A.D. 1850).
Information about these resources is recovered through scientific
archaeological investigations and oral histories.
Historic resources date after A.D. 1850 and are more than
50-years old. In the
planning area they are associated with early stagecoach and freight
travel, early ranching and logging activities, and in one case, scared
use by Native Americans.
Prehistoric
Archaeological
surveys, excavations, and artifact analyses have been conducted within
the planning area over the last 43 years.
Initial investigations by the
University
of Oregon
in the late
1950s were prompted by the construction of the Boyle Powerhouse and Dam
(Newman and Cressman 1959). Later,
as part of the proposed Salt Caves Hydroelectric Project, the City of
Klamath Falls
(1984-1986)
surveyed land and test excavated 20 sites within the planning area.
The
Upper Klamath River Canyon Project started in 1992, to collect the
canyon’s ecosystem data and develop a land use history of the area.
Surveys, excavations, and analyses have provided information
about prehistoric activities in the canyon.
Consultation with Native Americans has yielded information on
prehistory . . . and its
relation to the lives and culture of living people, and enhanced the
scope of our understanding of the prehistoric use of the canyon.
Over
100 prehistoric sites have been located in the upper
Klamath River
Canyon
.
The wide variety of known sites within the river corridor
demonstrates intense prehistoric use of the canyon by Native Americans.
Use of the canyon . . . dates back to at least 5500 B.C. (per
oral history); however, archaeological data indicates that most of the
sites . . . were occupied
from A.D. 900 to A.D. 1850 (Late Prehistoric Period) (Mack 1995).
(pg
38) Ethnographic
accounts (Silver 1978; Spier 1930; Kroeber 1925; Gleason 2001) and
artifacts recovered from sites within the planning area indicate the
area was used by a variety of cultural groups and at different times.
One group has been identified as the Shasta Nation of northern
California
.
In
addition, the federally recognized Modoc and Klamath Tribes . . . , the
Takelma of the upper Rogue River, and possibly the Pit River Indians of
northeastern
California
are known to
have used the area. Common
to all of these Tribes was the use of winter pit house villages, hunting
and fishing camps, and a subsistence pattern in which anadromous fish,
acorns (where available), large and small mammals, and various plants
were major parts of their diet.
(pg
39)
The wide range of artifacts from sites in the planning area shows that
use of the canyon by different Tribes changed over the last 2,000 years.
This is important because it shows that territorial boundaries
between the different Tribes using the canyon did not remain the same
through time (an assumption often made about the boundaries of
prehistoric culture areas), but changed as each group expanded or
decreased its Tribal area.
Historic (pg 39)
After
the 1850’s, Native Americans continued to use the canyon for hunting,
fishing, gathering, spiritual purposes, trade, and inter-Tribal
communications. However,
due to encroachment by Euro Americans, their activities were not as
prevalent as in prehistoric times.
Ethnographic and Euro American historic accounts (see Theodoratus
et al, 1989) present only a generalized level of information concerning
historic use by Native Americans.
Consultations
(oral) with Native Americans yield a different perspective on historic
use of the area. This
perspective reflects a continuous link between prehistoric and historic
cultural and spiritual uses, a linkage that has continued into the
present; tying the lives of members of the Klamath Tribes and Shasta
Nation with those of their ancestors who once inhabited the canyon.
Ethnographic
investigations in association with archaeological research (City of
Klamath Falls 1985) have identified use of one village site for
religious ceremonies associated with the 1870 Ghost Dance, a Native
American religious cult that first developed in the early 1870’s on
the
Great Plains
and then
spread to the Tribes in the west. Ceremonies
were conducted so the deceased would return to the earth and help the
living Native Americans regain control of their destiny.
This religious doctrine was apparently transmitted from the
Klamath Tribe, down the
Klamath River
, to the
northern California Tribes (Spier 1927).
This Ghost Dance site was probably part of the southward spread
of the religion.
The
upper Klamath River Canyon
has been used
extensively by Europeans since the 1850’s.
The terraces and flood plains along the river and several meadow
areas above the river were excellent locations for agricultural and
ranching activities. These
areas were the focus of European settlers in the canyon.
pg
40)
The earliest European explorers in the vicinity of the planning area
were members of Peter Skene Ogden’s Hudson Bay Company expedition of
1826 – 27 (LaLande 1987). In
their search for fur-bearing animals in southern
Oregon,
Ogden
’s party
traveled along the western canyon rim (within the planning area).
Unable to access the river because of the steep canyon wall, the
explorers left the canyon rim near RM 222.5.
Traveling southwest across the Pokegama Plateau (the area north
of the river) the party again reached the river near Copco Reservoir and
continued westward through the
Cascade Range
(LaLande
1987). Thirty years later
(1856) Mart Frain, a noteworthy local figure, followed the river
northward from the mining town of Yreka,
California, to
the
Klamath
Basin.
Upon reaching the
Klamath
Basin, Frain
began the first trade with local Native Americans.
Settlement
and ranching started in the 1860s when one of the first settlers, A. M.
Johnson homesteaded near the Klamath Hot Springs in 1860 (Hessig 1978).
Settlement increased after the construction of the
Topsy Road
in the
1870’s. (Bartoy 1995).
The
Topsy Road, a stagecoach freight road, is a prominent historical
landmark of the planning area. Topsy
Road parallels the river for 11.4 miles (5.1 miles in Segment 2, 6.3
miles in Segment 3) on the south and east side of the river.
Bisecting the
Cascade Range,
this road was officially opened for wagon and stage travel in 1875
between
Yreka
, California,
and the
Klamath
Basin.
However,
as early as 1865, freight for
Fort
Klamath
was carried up
the river canyon along a route closely approximating Topsy Road.
Topsy Road underwent three construction periods (1) initial
construction from 1874 to 1875; (2) a second construction period in
1887; when the steepness of the grade was lessened; and (3) the final
period of construction in 1890 when
Topsy Road and Topsy Grade were cut into a vertical basalt face.
From 1875 to the early 1900’s, when the road to Ashland,
Oregon, was improved, and the railroad reached Klamath Falls via a route
east of the river canyon, Topsy Road provided the only year-round access
to Klamath Falls and to towns east of the Klamath Basin.
Daily
travel occurred with an overnight stop at the Beswick Hotel and Klamath
Hot Springs in Segment 3, and livery stops at the Way Station Ranch
(0.5-mile north of the California/Oregon state line in Segment 2) and
Overlong Station, which is above Topsy Grade.
The
Beswick Hotel and Klamath Hot Springs complex in Segment 3 provided a
popular overnight stop for stage passengers and freight drivers, as well
as a vacation resort/health spa. The
resort had a hotel, post office, store, saloon, swimming pool,
restorative
hot springs,
dance pavilion, stables, plus living quarters for employees.
In
its heyday as a famous spa, the
hot springs
were visited
by such noted guests as President Herbert Hoover, author Zane Gray, and
pilot Amelia Earhart. The
first Beswick Hotel was constructed around 1870; a second hotel, built
in 1887, was destroyed by fire in 1915.
Stones
from the second hotel were used to construct a dance pavilion around
1920; this, too, was destroyed by fire.
The post office, store, and saloon, all housed within the same
building, swimming pool; stables; and living quarters for the resort
employees are still standing today and are visible from the road and
river.
Way
Station, a livery stable and log cabin associated with travel o
Topsy Road
, is still
standing. The location of
Overton Station, another livery stop, is identified by several poplar
trees above Topsy Grade.
Two
additional historic ranch sites are found along Topsy Road; Kerwin
Ranch, where the foundations and apple orchard are still visible, and
the Frain Ranch, purchased by Mart Frain in (pg
41) 1888 and deeded to his three sons in 1893.
The Frain Ranch contains the visible remains of a log cabin, root
cellar, barn, and garage. The
orchard, pasture lands, and the log cabin are visible from the river.
A
pioneer cemetery, the Way Cemetery, is located off Topsy Road and
contains the graves of Mart Frain and members of the Way, Ward, Ovelton,
and Hoover families (all early ranching families).
Topsy
School, at the
foot of Topsy Grade, was attended by children of the nearby ranches and
logging camps.
All
located within Segment 2, these historic sites display historical
markers containing brief, descriptive accounts, courtesy of the local
historical society. Two
other historic ranches within Segment 2, the Hoover
and Butler
Ranches are on the west side of the river.
In
addition to being a communication and travel corridor, the upper
Klamath River
played a major
role in the logging operations of the area.
The first cutting of timber started in the 1860s.
Nearby ranchers and farmers cut posts for fences, poles and
lumber for building construction, and fuelwood for home heating.
The first commercial cutting was done in 1888 on the Oregon
side north of
the river, east of Hoover Ranch, and south of the river around Kerwin
Ranch. Logs were pulled by
horses along a ground-level chute made of logs braced side-by-side, to a
landing at the rivers edge. These
logs were floated to a mill at Pokegema (later Klamathon),
California, in
1891 (Helfrich 1966).
A
major engineering feature of these logging activities was a wooden log
chute, known as the Pokegama log cute, which was cut into the western
canyon wall in Segment 3 and put into operation in 1892.
For ten years, logs were brought from the Pokegama Plateau by
train and unloaded at the top of the chute.
The logs were pushed onto the chute, and by gravity, slid down into the
river. The logs were then
floated down the river to the mill at the town of
Klamathon
.
At the height of its operation, 300 logs per day were carried
down the 2,000-foot chute and over 100 men were employed along the river
to facilitate movement of the logs downstream
Today the only reminder of the log chute is a cut at the top of the
canyon rim and a scar where the chute cut through the hillside, which
are both visible from the river and Topsy road.
Native
American Traditional Uses (pg 41)
Traditional
use by Native Americans of the upper
Klamath River
Canyon
began before
contact with Euro Americans and has continued into the present.
Today, members of the Klamath Tribe and the Shasta Nation
continue to use the canyon for spiritual purposes, hunting, fishing,
gathering, and other cultural activities.
Many
of the traditional use areas can be considered traditional cultural
properties. A traditional
cultural property is defined as a property that ‘is eligible for
inclusion in the National Register because of its association with
cultural practices or beliefs of a living community that (a) are rooted
in the community’s history, and (b) are important in maintaining the
continuing cultural identity of the community’ (National Register
Bulletin No. 38).
The
Klamath and Shasta consider the river and canyon sacred because of their
historical use by Tribal ancestors and present day use by Tribal
members. From a spiritual
perspective, the river expresses the values of life to the Klamath
Tribes.
Innumerable
stone cairns throughout the canyon attest to its long and continued
spiritual use. These cairns
are pages in the Klamath People’s history, a very real conduit to the
lives and spirits of those who walked the earth in the near and distant
past. Further, the land and
river are spiritually powerful to the Klamath People.
(pg
42)
In the Native American world view, unlike that of Euro Americans, the
land and the lives of the people who inhabit it are inextricably
intertwined; to destroy the land is to unravel the fabric of life in
which the people live. The
upper Klamath River is one of the few parts of the region left that has
been relatively untouched by development over the past 150 years.
For the Klamath and their neighboring Tribes, the river and its
canyon are very much a part of what makes them a people (Klamath Tribe
1989, personal communication).
A
similar value of the river canyon is expressed by the Shasta Nation; to
them this area represents a crucial link with the spiritual world:
“For
generations individual members, our spiritual leaders, and medicine
persons have traveled to
these burials to communicate with the Great Creator, to perform rituals,
and to prepare for specific religious and medicinal ceremonies.
The area contains places where our medicine people ascend, as
they have throughout history, to their position
. . . the first medicine power was received there, and the first
practitioners of that power were brought forth and taught there . . .
“Guidance for daily life and for crises that individuals in the
Tribe must face comes from those sites” (Hall 1985.)
“The
various forms of spiritual use of an area by Native Americans do not
fall within categories readily familiar to religions of western society.
Religious use of a particular area encompasses a wide range of
elements and observances.
"
Rituals
can be practiced on an individual level where a person observes a
particular practice as part of their daily activities.
Small group observances might involve a family group with a
religious specialist (shaman/doctor) who with esoteric knowledge has
special access to supernatural power often used for curing or
life-crisis events (for example, the death of a loved one).
Other rituals and ceremonies involve the participation of all
society’s members in events considered to be vital to the society as a
whole (essential resources such as fish, acorns, and epos).
These larger rituals renew and emphasize members’ needs for,
and dependence on, the total society.
The rituals must be performed properly according to
well-established rites that involved time, place, and symbolic objects
(Theodoratus et al. 1989).
The
concept of spiritual/supernatural powers is a basic element in all
Native American religions practiced in the planning area.
Native Americans in the planning area had/have strong development
of the religious concepts through their intimate day-to-day contact with
the environment (trees, rocks, springs, weather, shapes, and animal
life, etc.) many, which potentially contained power.
Spirit-quests by individuals at special locations embodied with
supernatural qualities were/are important (Theodoratus et al. 1989).
Native
Americans also value the canyon for other important cultural activities.
The river area has long been used for fishing, gathering, and
hunting; as a meeting place between the area’s various Tribes and
bands; as shared fishing villages; and as a site of inter-Tribal
exchange and communication. There
are no instream water rights for the Native Americans who use the
Klamath River
within the
planning area. The area
also contains archaeological and environmental information and material
that sheds light upon the culture and history of the Klamath, their
neighbors, and their ancestors (Klamath Tribe 1989, personal
communication).
Watershed Values (pg 60)
Water
resources are a key component in shaping the animal and plant
communities found within the planning area, and in providing recreation
opportunities. Factors
discussed in this section include beneficial uses and resource values,
energy generation, water rights, stream flows, water quality (including
that of Upper Klamath Lake and upstream segments of the Klamath River),
and aquatic habitat.
Although
the river within the planning area is the primary focus of examination,
upstream conditions substantially affect this portion of the river.
Additionally, tributary streams contribute streamflow to the
river and provide habitat. Where
relevant, characteristics of these streams will be discussed in the
appropriate sections of this chapter.
Beneficial Uses
The
appropriation of surface waters within the
Klamath
Basin
is governed by
Oregon
and
California
law, and the “
Klamath
River
Basin
Compact”
(Oregon Revised Statutes 542.620).
The Compact became effective in 1957 upon ratification by Oregon
and California
and acceptance
by the U.S. Congress. Article
III of the Compact addresses beneficial uses in the Klamath
River Basin.
The
Oregon Department of Environmental Quality (ODEQ) has expanded upon
these beneficial uses for the purpose of developing water quality
management programs for the upper
Klamath River
(Oregon
Administrative Rules 350-41-962). Established
beneficial uses include public and private domestic water supply;
industrial water supply; irrigation; livestock watering; salmonid
rearing and spawning; resident fish and aquatic life; wildlife and
hunting; fishing, boating, and water contact recreation; and esthetic
quality.
The
North Coast Regional Water Quality Control Board has established
beneficial uses for the
California
portion of the
Klamath River
.
These are broadly categorized as water supply, recreation, fish
and wildlife habitat, power generation, and scientific study.
Specific existing a potential beneficial uses for the
Klamath River
between the
state line and Iron Gate Dam have also been outlined.
Existing beneficial uses include municipal and domestic supply,
agricultural supply, groundwater recharge, freshwater replenishment,
commercial and sport fishing,
hydropower generation, navigation, water contact and non-contact
recreation, warm freshwater habitat, cold freshwater habitat, fish
migration, fish spawning, and wildlife habitat (North Coast Regional
Water Quality Control Board 1994).
Water Rights
Water
use upstream from and within the planning area affects streamflows in
the
Klamath River
.
The Oregon Water Resources Department (OWRD) is currently
conducting an
Oregon
general stream
adjudication for the Oregon
portion of the
Klamath
River Basin.
An adjudication is the
Oregon
statutory
process for quantification and determination of all rights to surface
water, the use of which is initiated before
February 24,
1909
(the date the
surface water code in Oregon
was
established) and federal reserved water rights.
The reserved water rights claims submitted by federal agencies
and the Klamath Tribes will be determined through this process.
The
OWRD process for acquiring water rights under state law has three steps.
Prior to receiving a water right certificate, a water user must
first apply for, and then receive , a water (pg
61) rights permit. In
order to “prove up” on the permit, a water user must begin putting
the water to beneficial use. Following
this period, the OWRD determines whether to issue a “perfected”
water rights certificate (OWRD, 2001).
Klamath
River
Within
the Oregon portion of the study area (Segment 1 and 2), PacificCorp is
licensed to divert up to 2,500 cubic feet per second (cfs) of Klamath
River water for the operation of the J. C. Boyle hydroelectric project
(Hydroelectric Commission of Oregon 1965).
The discrepancy between the hydraulic capacity of the powerhouse
(3,000 cfs) and the licensed diversion volume (2,500 cfs) will be
addressed during the FERC re-licensing process.
In
addition, PacificCorp has other pre-1909 water rights claims that were
acquired with the with the purchase of land adjacent to the river.
Two permits allow diversions from the
Klamath River
for
irrigation, stock, and domestic use.
The volume of water that could be withdrawn by these permits is
an insignificant portion of the total river discharge (less then
approximately 10 cfs).
The
BLM has filed a claim for instream flows in Segment 2 of the planning
area based on the Wild and Scenic
Rivers Act of 1968. In
the Act, Congress expressly reserved water for flow-dependent
outstandingly remarkable values. Flows
were claimed (Federal Reserve Claim 376,1999) for two outstandingly
remarkable values: fisheries (625 cfs from April 1 through June 15, and
525 cfs for the rest of the year), and recreation (whitewater rafting,
1,500 cfs between Memorial Day and September 30) (see table 2-12).
The BLM water right claim on the
Klamath River
is pending on
the Klamath Basin Adjudication.
The
Oregon Department of Parks and Recreation and the Oregon Department of
Fish and Wildlife (ODFW) applied to the Water Resources Department in
1989 for an instream water right on the Klamath Scenic Waterway (Segment
2). Based on the release
regime from the J. C. Boyle Powerhouse, the application requests 1,500
cfs for recreation and 550 cfs (not additive) for fish populations and
habitat. This application
is still pending.
The
Bureau of Indian Affairs, on behalf of the Klamath Tribes, has claimed
(Federal Reserve Claim 671, 1999) for future use 700 cfs year-round to
provide adequate migratory passage of anadromous salmonid fishes into
and out of the Upper Klamath River Basin (should the former range of the
anadromous fish habitat be restored).
Within
the
California
portion of the
planning area (Segment 3), the California State Water Resources Control
Board currently does not have any water use applications or claim of
rights on file.
Private
land
owners within
Segment 3 exercise pre-1914 water rights to divert water from the main
stem and from Shovel and
Negro Creeks to irrigate pastureland and hay fields.
(pg
62)
The “Klamath River Basin Compact,” provides guidance along with
other applicable laws for water rights administration in the
Klamath
Basin.
The major purposes of the Compact, as stated in Article I, are:
A.
To
facilitate and promote the orderly, integrated and comprehensive
development, use, conservation and control thereof for various purposes,
including, among others” the use of water for domestic purposes; the
development of lands by irrigation and other means; the protection and
enhancement of fish, wildlife, and recreational resources; the use of
water for industrial purposes and hydroelectric power production; and
the use and control of water for navigation and flood prevention.
B.
To
further intergovernmental cooperation and comity with respect to these
resources and programs for their use and development and to remove
causes of present and future controversies by providing (1) for
equitable distribution and use of water among the two states and the
federal government, (2) for preferential rights to use of water after
the effective date of this compact for the anticipated ultimate
requirements for domestic and irrigation purposes in the upper Klamath
River Basin in Oregon and California, and (3) for prescribed
relationships between beneficial uses of water as a practicable means of
accomplishing such distribution and use.
Tributary Streams
The
Oregon State Department of Forestry has a permit to use up to 10,000
gallons of water per day for dust abatement from an unnamed tributary of
the
Klamath River
near the
Topsy Road
in Segment 2.
An irrigation diversion is located on Hayden Creek, but is not
currently used.
In
Segment 3, water is diverted from the mainstem of Shovel Creek in two
locations and from near the mouth of Negro Creek (a tributary of Shovel
Creek) in one location. From
April 15 to October 15. These diversions supply up to 15 cfs to
irrigated meadows along the lower portion of Shovel Creek (Ichisaka
2001, personal communication). This
constitutes a relatively large percentage of total stream discharge
during the summer baseflow period.
Water rights for these diversions are based on
California's
doctrine of riparian water rights.
Streamflows
(pg 62)
Klamath
River
General
The
Klamath River
begins at the
outlet of
Upper Klamath
Lake
and flows to
the
Pacific Ocean
.
At the upstream end of Segment 2, the river drains approximately
4,080 square miles (not including the
Lost
River
sub-basin,
which occasionally overflows into the
Klamath River
drainage).
Late
winter and spring peak flows are derived primarily from snowmelt in the
drainage area of
Upper Klamath
Lake
and subsequent
releases from Link River Dam. Summer
flows in the river are derived from releases at Link River Dam,
groundwater discharge from volcanic aquifers, and some return flow.
Elevated flows in fall and early winter are a result of return
flow from irrigated areas south and west of
Klamath Falls
(BHI 1996.
The
Klamath Reclamation Project operated by the Bureau of Reclamation
(USBR), supplies water to about 240,000 acres of irrigated land and a
smaller area of national wildlife refuge lands.
Diversion of water for use by the USBR Project began in 1905.
In 1961, the completed USBR Project facilities were fully
operational (USBR 2000).
(pg
62)
Compared to pre-USBR Project conditions, flow regulation at
Upper Klamath
Lake
results in
higher and earlier peak flows in the
Klamath River
, decreased
summer minimum flows, and greater annual flow variability (BHI 1996).
In the planning area, these effects commingle with the effects of
diversions and releases related to hydropower generation.
Flow Modification Due To Operation of the J. C. Boyle Facility
The
operation of the J. C. Boyle facility varies according to water
availability, instream flow requirements for ESA-listed salmon
downstream from Iron Gate Dam (RM 190), and PacifiCorp’s FERC license.
A
minimum flow of 100 cfs is released at J. C. Boyle Dam to provide
instream flow for fish movement through Segment 1.
In addition to this continuous outflow at the dam, a series of
springs in the riverbed between the dam and the powerhouse (located near
RM 223) add another estimated 225 cfs of flow (on average), which
maintains a relatively constant flow of approximately 325 cfs during
summer. Flows in Segment 1
between the dam and the powerhouse are not subject to the daily
fluctuations that occur in Segments 2 and 3 that result from powerhouse
operations.
One,
both, or neither of the turbines at the J. C. Boyle Powerhouse may be
generating electricity at any given moment, depending on energy demand
and water availability. When
daily average river flows are less then about 3,300 cfs, the J. C. Boyle
facility is operated to produce power during periods of peak energy
demand (PacificCorp 2000). This
type of operation is referred to as “peaking” or “load
following.”
When
neither turbine is in use, water flowing into J. C. Boyle Reservoir is
stored for later use. As a
result of peaking operations, streamflow and water surface elevations
(“stage”) in the river below the powerhouse can fluctuate throughout
the day. Stage fluctuations
below the dam and powerhouse are limited to a 9 inch per hour ramp rate,
as per the 1956 FERC license (PacificCorp 2000).
Depending on flow levels, this equates to changes in discharge
that range from 400 cfs per hour, to approximately 950 cfs per hour (see
Figure 2-1).
Daily
Average Streamflows
Streamflows
have been measured since January 1959 by the USGS at a gauging station
0.7 mile below the J. C. Boyle Powerhouse (USGS gage 11510700).
The streamflow record at this gage is representative of flows in
Segments 2 and 3, although flows through Segment 3 are slightly higher
and slightly less variable then flows in Segment 2, due to tributary
inflow from Shovel Creek (10 to 100 cfs), Hayden Creek, and minor
intermittent tributaries.
For
this planning effort the data set has been converted to water years,
which are defined by the USGS as beginning on October 1 and ending the
following September 30, and are designated by the calendar year in which
the water year ends. Data
is not available for water years 1972-74, 1980-82, and 1988.
Average
daily discharge data from water years 1967 through 2000 show an average
annual flow of 1,839 cfs. Mean
monthly flow data show that average monthly flows are higher December
through April and lowest June through September (Table 2-13).
Average daily discharges in the 300 to 400 cfs range can occur
any month of the year, as can average daily discharges greater than
1,600 cfs.
Daily Fluctuations in
Streamflow and Stage
Peaking
operations cause significant daily stage and discharge fluctuations in
the river. The effects of
daily powerhouse operations on streamflow were analyzed using discharge
data collected every 30 minutes at the USGS J. C. Boyle gage.
This analysis was limited to January and July 2000, which are
representative average winter and summer flows.
During
low flow periods (summer/fall), there is typically only one turbine
generating for a portion of any given day.
On a daily basis during the low flow season, discharge below the
(pg 65) powerhouse generally ranges from 300 to 400 cfs (baseflow,
composed of outflow from the dam and contributions from springs) to
approximately 1,500 cfs (baseflow plus turbine throughflow).
When there is sufficient water and consumer demand both turbines
may be used, and flows can ramp from baseflow to 3,000 cfs within a few
hours (see Figure 2-2). Alternatively,
there may be days when no water is released in excess of the minimum
bypass flow.
Discharge
in Segments 2 and 3 is more variable during the high flow season (late
winter/early spring) than during the low flow season (see Figure 2-2).
As a consequence of tributary inflows, baseflow increases to
approximately 700 cfs. Higher
average daily flows allow frequent two-turbine peaking during this
period. Depending on how
the J. C. Boyle complex is operated, discharge fluctuations within a
24-hour period can range from 50 to more then 2,500 cfs.
Flow
ramping causes river levels downstream from the powerhouse to vary
widely on a daily basis. These
effects persist for the length of Segments 2 and 3. Measurements at the
USGS gauging stating indicate that daily fluctuations (at this site)
during the low flow season may exceed 2.5 feet. Though fluctuations on
the order of 1.75 feet are more common.
Portions of the streambed are dewatered and exposed during
intervals when no poser is generated.
As with discharge, stage fluctuations during the high flow season
are more variable. On days
when the J. C. Boyle complex is operated for peaking power, stage can be
raised or lowered by approximately 2.2 feet over a 6-hour period.
Conversely, when the complex generates power at a steady rate
there is no appreciable stage variation.
Because stage fluctuations vary according to channel geometry,
the magnitude of stage fluctuations in Segments 2 and 3 is not constant
between different locations; in confined reaches of the river,
fluctuations may be higher, while in reaches with low beaches,
fluctuation may be lower.
Peak
Flows
Floods
with recurrence intervals of about 1.5 years are generally considered to
be the most geomorphically effective (Dunn and Leopold 1978).
Analysis of peak flow data from the USGS J. C. Boyle gage
suggests that flows of between 3,100 and 4,700 cfs occur about every 1.5
years in Segments 2 and 3. Spills
from J. C. Boyle Dam into Segment 1 occur in about tow out of every
three years. Due to flow
regulations and diversions, peak flows in Segment 1 are currently of
lower magnitude and shorter duration then would occur were the river
unregulated. The largest
peak flow recorded at the J. C. Boyle gage occurred in February 1996.
Discharge during this flood exceeded 11,500 cfs.
Tributary Streams with
the Planning Area
One
large seep complex and two relatively large perennial streams enter the
river in the planning area, as well as numerous smaller streams and
springs. Depending on the
season, total accretions between J. C. Boyle Dam and the slack water of
Copco Reservoir range approximately from 230 cfs to 700 cfs.
The greatest portion of this inflow occurs in Segment 1, where an
extensive zone of seepage into the riverbed contributes, on average,
about 225 cfs to the river (Hand and Gerlach 1964; PacificCorp 2000).
Except for this seepage zone, the magnitude of tributary inflows
are relatively minor and of much more importance locally (as coldwater
refugia, for example) than on the scale of the
Klamath River
as a whole.
Shovel
Creek enters the
Klamath River
near RM 206.
Although Shovel Creek drains a large watershed (51 square miles),
most summer flow is derived from springs in the Negro Creek and Bear
Creek drainages. As
discussed above, a substantial portion of summer baseflow is diverted
for irrigation use near the mouth of Shovel Creek.
Winter peak flows are on the order of 100 cfs (PacificCorp 2000).
The summer base flows are about 20 cfs when irrigation diversions
are not in use (Beyer 1984).
(Page 66 is Figure 2-2. Daily Hydrographs Below J. C. Boyle
Powerhouse)
(pg
67)
Hayden Creek drains approximately 28 square miles and has fewer springs
than the Shovel Creek drainage. Measured
summer discharges about two miles upstream from its mouth are on the
order of 0.5 cfs. There are
no active diversions from Hayden Creek within the planning area,
although the stream intersects an irrigation ditch (diverted from the
river) at its mouth.
Peak
flows from Hayden Creek and Edge Creek have been estimated using a
variety of methods – refer to the “Topsy Pokegama Landscape
Analysis” (BLM 1996) for this information.
The
hydrologic cycle in tributary watersheds within the planning area has
likely been affected by the extensive road network.
Roads can change infiltration rates, intercept and divert
subsurface flow, change the drainage area of small streams, and decrease
the time it take for runoff to reach streams.
This can cause peak flows to increase (Furniss et al. 1991).
Incision of streams into their floodplains has also affected
baseflows, due to the loss of the “sponge effect” of the
floodplains.
Water
Quality (pg 67)
Klamath
River
Water Quality Standards
Water
quality standards have been set by the ODEQ for Klamath
Basin waters
and specifically for the Klamath River
from
Upper Klamath
Lake
to the state
line (Oregon Administrative Rules 340-41-965).
In
California,
the North Coast Regional Water Quality Control Board (1994) has
established water quality objectives for the upper Klamath River
from the state
line to Iron Gate Dam (see Table 2-14).
303(d)-Listed
Segments of the
Klamath
River
The
mainstem Klamath River upstream from, within, and downstream from the
planning area is included on lists of water quality limited water bodies
(referred to as 303[d] lists) prepared in 1998 by the ODEQ and
California North Coast Regional Water Quality Control Board.
In each listed segment, state standards are regularly exceeded
for numerous water quality parameters (Table 2-15).
For some water quality parameters, data is not available to
assess compliance with state standards.
Water
quality of the
Klamath River
within the
planning area is affected by upstream point and non-point sources of
pollutants:
·
The
source of the
Klamath River
,
Upper Klamath
Lake
, is a
hyper-eutrophic lake that supports an abundant algal population.
Lake
water quality
varies according to season and annual amount of runoff entering the
lake. Recent studies have
pointed out that the nutrient-enriched condition of the lake, though
natural, has likely been accentuated as a result of agricultural
activities, livestock production, logging, urban development, and
reclamation of wetlands for agriculture (Eilers et al. 2001, Snyder and
Morace 1997). Massive
blooms of blue-green algae typically occur in the lake in the summer.
Daily cycles of respiration and decomposition result in
extremely high pH levels and wide fluctuations in levels of
dissolved oxygen and carbonic acid.
·
The
Link River, which is that portion of the Klamath River flowing between
the outlet of Upper Klamath Lake and the upstream end of Lake Ewauna, is
included on the 1998 Oregon 303(d) list for temperature, pH, and
chlorophyll-a.
(pg
68)
·
Drainage
water from portions of the USBR Klamath Project is conveyed back into
the Klamath River via the Klamath Straits Drain, which enters the river
upstream from Keno, Oregon. Water
quality standards for dissolved oxygen, fecal coliform (from
duck poop in the lower refuges ~ typist), temperature (from
summer shallow water storage in the lower refuges and hot water seep
springs ~ typist), pH (naturally
occurring in the volcanic springs and seeps ~ typist), chlorophyll-a
(from upper Klamath Lake ~
typist), and ammonia are not being met for this water body (ODEQ
1998). (Wonder why they keep
using data from a 1998 report? Could
it be that subsequent scientific studies by ODEQ show a decrease in
these pollutants? ~ the typist) Effects
to water quality in the river depend on the proportions of return flow
to river water and vary by constituent (Mayer 2000).
·
The
Klamath River
upstream from
Keno Dam to the upper end of
Lake
Ewauna
is included on
the 1998 303(d) list due to high temperatures, low dissolved oxygen
levels, high pH levels, and high chlorophyll-a abundance.
Additionally, measured concentrations of un-ionized ammonia in
this reach are above criteria set by the ODEQ and the Environmental
Protection Agency (ODEQ 1998).
The
Klamath
River
between
Keno Dam and the California
border
(which includes Segments 1and 2) is included on the 1998 303(d) list for
exceedance of Oregon
temperature
standards. Though generally
within the range of standards, other water quality parameters, such as
dissolved oxygen and pH, may detrimentally affect beneficial uses and
outstandingly remarkable values (including fisheries, recreation, and
wildlife) in Segment 2 during certain flow conditions.
The
Klamath
River
between
the state line and Iron Gate Dam is listed for high nutrient levels,
organic enrichment, low dissolved oxygen, and high temperatures
(California State Water Resources Conservation Board 1999).
Water
Quality Trends (pg
69)
Water
quality within the planning area is monitored monthly by the ODEQ at
several locations above Keno Dam and at the USGS J.C. Boyle gage. The
City of
Klamath
Falls
(1986)
monitored water quality at several locations between Keno Dam and Copco
Reservoir during 1984 and 1985, in relation to the proposed Salt
Caves
project
(Table 2-16).
Additionally,
PacifiCorp monitored temperature, dissolved oxygen, pH, total dissolved
gas, and specific conductivity at several sites between the Link River
Dam and the Iron Gate Powerhouse between 1994 and 1995 (PacifiCorp
Environmental Services 1996).
Within
the planning area, dissolved oxygen (DO) levels increase between the
upstream and downstream end of Segment 1, are reduced when flows are
released at the powerhouse, and then increase between the powerhouse and
the downstream end of Segment 3 (PacifiCorp 1996; PacifiCorp 1998).
This
longitudinal pattern reflects two primary influences on DO levels: (1)
the balance between relatively high quality spring inflows and water
from J.C. Boyle Reservoir, and (2) the effect of turbulent aeration
caused by rapids. On a daily basis, it is likely that DO levels change
as water temperatures respond to solar heat inputs and fluctuating flow
levels downstream from the powerhouse.
(pg
70)
As discussed above, upstream water quality limitations may be
responsible for a substantial portion of water quality problems within
the planning area. Water quality downstream from pollution sources often
improves due to dilution and/or mixing. Dissolved oxygen concentrations
increase between
Keno
Bridge
and
the J. C. Boyle Powerhouse as result of aeration and dilution of
organically enriched waters; pH levels decrease between those two sites,
likely for similar reasons. Were it not for high quality groundwater
entering the river in Segment 1, the effect of dilution within the
planning area would be minimal, especially during the low flow season,
when water quality problems are most critical.
Water Temperature Measurements (pg
70)
Water
temperatures in the planning area vary with season and by segment.
Within both the river and tributary streams, temperatures are controlled
by interactions between streamflow, channel geomorphology, and riparian
vegetation. In the river, altered flows and, to a lesser degree, altered
channel geomorphology and riparian vegetation have likely adversely
affected water temperature and warming rates.
(pg
71)
Highest
water temperatures occur June through August, in conjunction with high
local air temperatures and low flows. Daily summer temperature
fluctuations are lowest in Segment 1 and greatest in Segments 2 and 3.
Because of the stable flows and springs, temperatures in
Segment 1 remain relatively constant from day to day, and are typically
around 70 degrees Fahrenheit in August and 48 to 53 degrees Fahrenheit
in early spring. Where the flows from Segment 1 meet the releases from
the Powerhouse, an abrupt mixing zone occurs.
Mid-day
peaking operations at the J.C. Boyle Powerhouse cause significant daily
temperature fluctuations in Segments 2 and 3. Summer temperatures
typically range from approximately 70 degrees Fahrenheit in early
evening, coincident with the passage of large volumes of reservoir
water, to approximately 58 degrees Fahrenheit in early morning hours, a
result of nighttime cooling (City of Klamath Falls 1986). An additional
cause of temperature fluctuations is the alternating source of water in
this reach (i.e., spring-dominated vs. reservoir-dominated flows).
Because the springs are much cooler than the reservoir water, higher
water temperatures in Segments 2 and 3 correspond to higher releases
from the powerhouse (Figure 2-3). At flows near 600 cfs, average water
temperatures at the upstream end of Segment 2 are near 61 degrees
Fahrenheit, while at flows near 1,800 cfs (one turbine) average water
temperatures are near 68 degrees Fahrenheit.
When
flows from the powerhouse are stable, water temperatures in Segments 2
and 3 are also relatively stable. During periods when peaking occurs,
the daily minimum temperature is reduced and the daily range of
temperatures is increased. The rate of temperature change associated
with peaking operations is generally faster than the rate at which
temperature changes due to changes in ambient air temperature (Figure
2-4).
Effects of Reservoirs on Water Quality (pg
72)
Instream
reservoirs such as J.C. Boyle and Keno can improve or degrade water
quality, depending on factors such as reservoir size and shape,
reservoir operations, climatic conditions, time of year, and upstream
water quality. According to one source (City of Klamath Falls 1986), the
presence of instream reservoirs can reduce pH, bacterial counts,
nutrients, sediments and turbidity, biological oxygen demand, and
settling of algal loads. A more recent analysis of nutrient dynamics in
the
Klamath
River
suggests
that the series of reservoirs do not function as nutrient sinks, perhaps
as a result of nutrient cycling within the reservoirs (Campbell
1999).
Effects of Land Management on Water Quality
Water
quality within the planning area is affected primarily by hydroelectric
facilities and operations and the character of water flowing into the
planning area. Because the
Klamath
River
drains
such a large area, it is unlikely that land management activities such
as timber harvest or grazing within the planning area have a substantial
effect on overall water quality within the river. However, land
management actions can affect habitat quality (and beneficial uses) at
varying scales within the river, and can profoundly affect water quality
within tributary streams. As the land within the river canyon is
somewhat inaccessible and generally receives special management
attention, the most significant land management effects on water quality
and habitat quality in the river are related to the location and
condition of the road network.
Effects of Water Quality on Beneficial Uses and ORVs (pg
73)
High
water temperatures can affect beneficial uses indirectly, principally
through the relationships between water temperatures, dissolved oxygen,
and fish health. Low dissolved oxygen levels impair fish health.
Dissolved oxygen levels decrease as temperature increases.
Increased temperature can also enhance algal productivity.
Algae
can impart a bad odor to water and a bad taste to game fish. As massive
quantities of blue-green algae decay, the biological oxygen demand
increases, and dissolved oxygen concentrations decrease to levels that
are harmful to fish. This effect can be partially offset by aeration
occurring in high gradient reaches of the river. Conditions that favor
algal growth include shallow turbulent water, hard water,
well-illuminated and warm water, and high phosphorous concentrations
(FERC 1990). Such conditions are present in some reaches of the river
within the planning area, especially in Segment 1.
Dissol
ved
organic matter within the water contributes to the distinctive coffee
color and foam that is often noted about the Klamath River

Tributary Streams
(pg 74)
Water
quality data is generally lacking for tributary streams within the
planning area. Water temperature data includes a continuous temperature
data set measured at the mouth of Shovel Creek during 2000 and 2001and a
series of “spot” measurements in various streams during the summer
of 2001.
Temperature
and other water quality parameters, such as dissolved oxygen and pH, may
detrimentally affect beneficial uses and outstandingly remarkable values
(including fisheries, recreation, and wildlife) during certain flow
conditions.
The
temperature data set for Shovel Creek is reflective of the springs that
comprise summer baseflow in this stream (Figure 2-5). A field survey of
instantaneous temperatures conducted in August 2001 suggests that some
warming occurs between the mouth of Bear Canyon and the mouth of Shovel
Creek (over a distance of about 2.1 miles), but is limited by the
contribution of Negro Creek flows, the northern aspect, and the closed
canopy riparian forest. The
effect of the Shovel and Negro Creek diversions on water temperatures in
those streams is uncertain, though other aspects of aquatic habitat may
be adversely affected (Beyer 1984).
(pg
75)
In
May 2001, water temperature at three springs adjacent to the river
downstream from the J.C. Boyle Powerhouse ranged from 50 to 60 degrees
Fahrenheit. Temperatures at the mouths of Chert Creek (near RM 210) and
Hayden Creek were 60 and 57 degrees Fahrenheit., respectively. Although
both of these streams are spring-fed, warming occurs as they flow across
broad meadows and south aspect slopes (BLM field notes).
Riparian
roads adjacent to tributary streams may impair water quality, habitat
quality, and fluvial processes. In the most severe cases, where roads
are located extremely close to streams (such as along Chert Creek),
streamflow may be captured by road surfaces. In other situations,
riparian roads and stream crossings limit coarse woody debris (CWD)
recruitment, stream shading, and fish/herptile passage, and may
contribute runoff and fine sediment to stream channels.
The
length of roads within riparian reserves of tributary streams
(equivalent to the width of one site potential tree, or 140 feet), as
well as their effect, varies between segments. Riparian roads adjacent
to tributary streams in Segment 1 are short and do not appear to be
causing resource damage. Riparian road length is greatest in Segment 2
(see Table 2-17). Of greatest concern in this segment are the roads that
parallel portions of Chert and Way Creeks; the remainder cross, rather
than parallel, streams. In Segment 3, relatively long road segments
parallel Shovel and Hessig Creeks. While the Hessig Creek road likely
affects runoff and channel processes in that ephemeral stream, the
portions of the
Shovel
Creek Road
(and
associated spurs) that pass through forested areas probably have a
detrimental effect on stream shading, wood recruitment, and sediment
delivery to that stream.
Major
Tributaries of the
Klamath
River
Planning
Area (pg 80)
Tributaries
within the canyon function as conduits for sediment and organic debris
(BLM 1996). These materials originate on hillslopes and move through
stream channels. These watershed products (sediment, course woody
debris, and organics) are especially important for gravel bar and
floodplain development, pool formation, and aquatic resource
productivity in the
Klamath
River
system.
The mouths of tributary streams may also serve as important aquatic
habitat refugial areas during flood events. Where tributary waters mix
with the
Klamath
River
,
areas of relatively good water quality may persist through the year.
Four
important tributaries enter the river within the planning area: Rock,
Hayden, Shovel, and Edge Creeks.
Rock
Creek is
a small tributary that meets the river at approximately RM 214. Rock
Creek provides supplemental flows during spring and winter; its natural
flow is supplemented by water pumped from
Meiss
Lake
during
wetter years. Increased suspended sediments have been noted in the river
during periods of pumping (City of Klamath Falls 1986). The entrance to
the creek from the river is steep and limits fish passage upstream of
the mouth.
Portions
of Rock Creek have been affected by road construction and maintenance.
The channel has apparently been bulldozed and straightened to protect
the bridge where
Topsy
Road
crosses
the stream. The stream in this area is no longer connected to its
floodplain, channel form has been simplified, and as a result the extent
of riparian communities has been reduced.
Hayden
Creek enters
the river approximately one river mile above the state line. Hayden
Creek flows perennially, though during summer the flow near its mouth is
restricted to subsurface pathways and perennial pools. As it enters the
planning area, Hayden Creek flows in a step-pool channel (alternating
between boulder cascades and plunge pools) through a narrow canyon that
widens somewhat in two locations. As it nears the river, Hayden Creek
enters a wide valley into which the stream has entrenched and formed a
new floodplain. The channel assumes a pool-riffle morphology in this
reach, with some side channel development.
Riparian vegetation is moderately abundant and consists of Oregon
ash,
willow species, ponderosa pine, and sedge species. The relic floodplain
is now a dry meadow, the low parts of which may be seasonally inundated.
Some gully development is apparent in portions of the relic floodplain.
Downstream
from Hoover Ranch, the stream briefly flows through a steep canyon
before opening up again at its mouth. An irrigation canal (from the
Klamath
River
)
diverts flow at the mouth of Hayden Creek and prevents full connectivity
of the stream to the river. A small irrigation diversion had been
developed on Hayden Creek approximately 0.25-mile upstream from the
mouth, likely to irrigate the lower field of Hoover Ranch. The
irrigation diversion point has subsequently blown out. Two wet meadows
are adjacent to the mouth of Hayden Creek, one to the east and one to
the northwest
(pg
81)
Shovel
Creek is
the most significant tributary within the planning area. It enters the
river upstream from RM 206. A major tributary to this stream is Negro
Creek, which joins Shovel Creek less than a mile from the river. Both of
these are small streams, averaging not more than 15 feet wide. As they
enter the planning area, these streams flow through moderately steep and
confined valleys. Shovel Creek enters a wider valley approximately 1.6
miles upstream from the river, while Negro Creek remains moderately
confined for all but the lower 0.3 miles of its length.
The
unconfined portions of both streams are responsive to changes in
watershed and riparian conditions, and thus show some evidence of past
and recent land management. Stream channels have incised by perhaps one
to three feet, partly as a result of increased runoff and partly as a
result of reduced instream CWD. The active channels have widened and
contain few deep pools. Loss of gravel storage areas and increased fine
sediment contributions could also be impairing habitat quality (Beyer
1984). Currently, the streams are cobble-dominated systems that have
fairly low sinuosity and sparse functional CWD. A few pockets of gravel
were noted during stream surveys in the river below the mouth of Shovel
Creek. Shovel Creek is a primary a source of gravel for the mainstem
river in the lower portion of Segment 3.
In
the vicinity of the bridge near its mouth, Shovel Creek has been
channelized in the past to prevent bridge failure during peak flows.
Coarse sediment and CWD accumulate upstream from the bridge during these
events and restrict the conveyance of floods. The bridge and associated
structures have been threatened during such events at least three times
in the past 40 years (Miller 2002, personal communication). These
occurrences suggest that the volume of sediment moving through the
stream is not in balance with the ability of the stream to transport it,
the size of the bridge is not adequate, or both.
Riparian
communities change along the length of Shovel Creek, with the amount of
stream cover increasing with distance from the mouth (Beyer 1984).
Towards the mouth, grass is the dominant vegetation, with a narrow
fringe of hardwoods and blackberry along the stream.
Upstream, a closed canopy forest is present along the stream, the
composition of which shifts from hardwood dominated to conifer dominated
as the stream gains elevation. Portions of the riparian area have been
logged in the past, though there are no extensive anthropogenic openings
in the forest. Similar patterns exist in Negro Creek, though portions of
its drainage have been harvested recently.
The diversion of Shovel and Negro Creek waters for irrigation (and the
maintenance of instream irrigation diversions) has had adverse affects
on fish habitat (Beyer 1984). The irrigation diversions lower stream
flow from late spring through early autumn.
Edge
Creek enters
the river less than a mile downstream from Shovel Creek. Only a very
short length of Edge Creek is within the planning area. This consists
primarily of a steep drainage flowing down from the canyon rim, though
the stream gradient decreases substantially near its mouth. Edge Creek
flows under an irrigation ditch near its mouth.
During high flow periods, runoff from Edge Creek is captured by
the irrigation ditch (Miller, personal communication, 2002).
Other
minor tributaries within
the planning area include Chert, Way, and Frain Creeks. These streams
enter the river at steep inclinations. Each of these streams is
spring-fed and provides habitat for aquatic invertebrates and herptiles.
Instream and riparian conditions within and along these streams vary,
although an array of potential problems have been identified. These
include poorly functioning stream crossings, riparian roads, grazing
impacts, and conversion of riparian vegetation to upland types.
Aquatic Species/Habitat (pg 85)
The
dams on the
Klamath
River
have
affected fish species distribution throughout the Klamath
Basin.
Historically, theKlamath River
was
a passageway for anadromous fish, salmon, steelhead, and Pacific lamprey
as they migrated to various tributaries of the
Klamath
River
and
Upper
Klamath Lake
(ODFW
1997). These fish runs were halted as early as 1910 by the construction
of Copco I Dam, completed in 1917, which permanently blocked fish
passage (City of Klamath Falls 1986). Five more dams were built on the
upper Klamath River-Copco II and lron Gate are located in
California
,
and Link
River,
Keno, and J.C. Boyle Dams are located in
Oregon
(PacifiCorp
2000). J.C. Boyle, Keno, and Link River Dams have fish ladders intended
for trout migration. Only J.C. Boyle Dam has a screening facility to
prevent entrainment of fish into the power diversion canal.
Connectivity
of the planning area segments to the upper and lower portions of the
Klamath
River
has
been impaired by alterations in water quality and development of the
river for commercial purposes including dams, diversions, and dikes.
The
major human impact to aquatic habitat over the last 150 years has been
the fragmentation and loss of components of the marsh, lake, and stream
system in
Klamath
Basin
(ODFW
1995). The basin floor was developed for agriculture, which included
extensive diking, channeling, draining, and loss of marshlands.
Diversions were constructed on many streams and rivers in the Klamath
system, causing dewatering and physical blockages for both upstream and
downstream migrating trout. Cattle grazing also contributed to channel
degradation in some locations.
Alteration
in lake alkalinity and water quality limited outflow may have increased
contributions as a result of the loss of adjacent marshlands in the
upper basin.
Lake
,
marsh, and riparian rearing habitat and functioning migration corridors
have been lost as a result. Much
of the impacts have occurred on private lands and are affecting the
aquatic condition of the planning area.
The
wild and scenic river segment of the upper
Klamath
River
is
inhabited by a diverse assemblage of fish species; at least 10 known
native species occur (Table 2-21). Three species of note occur in the
wild and scenic river segment (redband trout,
Lost
River
sucker,
and shortnose sucker) and shall be addressed independently. The other
native species found in the river include Klamath smallscale sucker,
blue and tui chub, Klamath speckled dace, sculpin species, and lamprey
species (City of Klamath Falls 1986). The Klamath largescale sucker, a
federal species of concern, has been found in J.C. Boyle Reservoir and
potentially occurs in the planning area (USDI-BLM 1990).
Lost
River (Deltistes
luxatus)
and shortnose (Chasmistes
brevirostris)
sucker are large, long-lived and omnivorous lake-dwelling species that
generally spawn in rivers, streams, or springs (Beuttner and Scoppettone
1990). These two species likely occur in the wild and scenic river
segment of the upper
Klamath
River
.
Although utilization has not been documented, both species have been
documented in upstream and downstream reservoirs (City of Klamath Falls
1987; Beuttner and Scoppettone 1991). Both species were federally listed
as endangered in 1988, and state listed as endangered 1991 (ODFW 1995).
The U.S. Fish and Wildlife Service (USFWS) completed a federal recovery
plan in 1993. The planning area was listed as proposed critical habitat
(unit 3) for both
Lost
River
and
shortnose suckers in 1994 (Federal
Register Vol.
59, No. 230).
Klamath
redband trout are currently the primary game fish inhabiting the river.
The upper
Klamath
River
from
Keno Dam to slackwater of Copco I Reservoir has been identified as (pg
86) wild trout managed fisheries (ODFW 1997; CDFG 2000). The
Klamath
River
from
the Keno Dam downstream to the state line was one of the first three
rivers designated in 1978 by the ODFW as a wild trout stream. From the
state line to Copco Reservoir, the Klamath River has been managed by the
California Department of Fish and Game as a wild trout area since 1974
(CDFG 2000).
No
nonnative hatchery trout have been stocked in the
Oregon
reach
of the
Klamath
River
since
1978, or in the California
reach
since 1974. The California Department of Fish and Game and a private
organization cooperated to raise and plant native stocks of trout into
Shovel Creek between 1985-1990.
The
concern for and importance of this wild rainbow trout fishery has been
acknowledged not only by state designation, but by public and private
concerns and also by state and federal government agencies as evidenced
by the following:
- The
National Park Service, in its 1982 nationwide rivers inventory,
recognized the “excellent trout fishery” of the
Klamath
River
.
- The
Northwest Power Planning Council designated the upper
Klamath
River
as
a protected area in 1988, to protect the resident rainbow trout
population.
- The
1986
Pacific
Northwest
rivers
study for Oregon
gave
their highest resource value rating to the Klamath River
based
on the wild trout population.
- The
ODFW chose the wild rainbow populations of the
Klamath
Basin,
specifically those of the Klamath River, as the first of many in the
state to be studied, to better understand how stocks of wild trout
have adapted to their particular environments.
The
Klamath system produces an immense quantity of aquatic invertebrates
such as caddisflies, mayflies, midges, and stoneflies, which provide a
primary food source for trout (USDI-BLM 1990). Crayfish are considered
abundant and would be an important part of the trout’s diet.
Redband of the
Klamath
River
(pg
87)
The
Oregon
Basin
redband
trout occupies remnant streams in seven Pleistocene lakebeds in
Oregon
(ODFW
1995). Populations in each of these basins are completely isolated by
natural geological features, except for those in the
Klamath
Basin.
After Lake
Modoc
cut
an outlet to the
Pacific
Ocean
via
the
Klamath
River, the lake became smaller as the outlet trenched down (Behnke
1992). After the connection to the ocean was made with the
Klamath
River
,
steelhead were known to migrate from the ocean to the
Klamath
Lake
area.
The novel traits in the
Upper
Klamath
Basin
group
may have resulted from the interbreeding of the newly invading O.
mykiss with
the original resident fish of the basin (ODFW 1995; Behnke 1992).
Thousands
of years of adapting to a drying environment have enabled populations of
Klamath
Basin
redband
trout to feed at higher temperatures than most other western trout,
which typically are affected by increases in temperature (Behnke 1992).
Native stocks of redband in the Klamath Watershed have also evolved
resistance to an endemic bacterial disease, (Ceratomyxa
shasta),
which is highly lethal to nonnative trout (ODFW 1997).
Klamath
River
redband
confront many environmental constraints, including low summer base flows
and concurrent decreasing water quality, lack of spawning gravel, cyclic
water fluctuations from power generation, and potential competition from
nonnative warm water fish (City of Klamath Falls 1986). Despite these
problems,
Klamath
River
redband
in the planning area have been able to sustain a sport fishery (ODFW
1997).
The
loss of access between lakes, marshes, and streams has interfered with
the migratory life histories of
Klamath
Basin
redband
trout (ODFW 1995). Population productivity has been compromised because
of the loss of the important rearing areas. Gene flow among the Klamath
Basin
populations
has ceased or is reduced and many of its populations are seriously
fragmented. Some populations have likely been completely lost.
The
trout population that persists in the wild and scenic river segment of
the upper Klamath River
could
be described as locally productive; however, due to passage limitation
above and below the wild and scenic river segment, this population is
very restricted in distribution. Potentially,
the life history options that carried this population through natural
drought cycles, or provided for recolonization in the event of die off,
are no longer available.
Close
genetic similarity of rainbow trout exists between multiple stream
populations in areas above
Upper
Klamath Lake
including
Spring Creek and Trout Creek, and areas below including Spencer
Creek
and
Bogus Creek (Buchanan et. al. 1994). This genetic similarity suggests
that the upper
Klamath
River
trout,
including fish within the wild and scenic river segment, are closely
related. In addition, ODFW noted genetic uniqueness of the populations
of trout in the basin as evidence of a history of isolation from other
evolutionary lines of trout (Buchanan et al. 1994).
(pg
88)
Based on the genetic analysis of upper Klamath native trout
indicating uniqueness and isolation from other trout populations,
support exists for the classification as a separate subspecies (Klamath
redband trout) scientific name Onchorhynchus
mykiss newberri of
the trout of the upper basin including the affected wild and scenic
river segment of the upper Klamath River.
This
classification nomenclature was originally derived from early collection
of specimens from the 1850s (Behnke 1992). While this classification has
not been formally accepted, protection of genetically distinct stocks is
an important management goal (USDIBLM 1995; ODFW 1997). The redband,
including those within the wild and scenic river segment, are included
in
ODFW
Klamath
Lake
gene
conservation group of the Oregon
Basin
redband
trout complex that is listed as a State sensitive species (ODFW 1997).
The
“Upper Klamath River Wild Trout Management Plan 2000-2004” (CDFG
2000) makes no distinction between these Klamath River trout stocks and
other rainbow trout. The purity of the wild and scenic river segment of
the upper Klamath River
strain
comes under question as a result of Iron Gate
hatchery
supplementation from 1970-1981 into Copco Reservoir.
Iron
Gate Hatchery steelhead stocks were founded on native fish, but some
eggs were imported from
Trinity
River
hatchery
and Cowlitz River Hatchery in
Washington
(Klamath
River Basin Fisheries Task Force 1991). The introduced nonnative strains
of rainbow trout into the
Klamath
Basin
probably
have not been able to reproduce due to their susceptibility to the
endemic disease, C.
Shasta .It
is hoped that the genetics of the native trout in the affected reach
would endure only minimal negative effects. (ODFW 1997).
Informally,
California Department of Fish and Game biologists support ODFW
classification of the Klamath redband trout as a separate subspecies of
rainbow trout (Rode 2002, personal communication).
In
high-gradient systems trout production can be greatly affected by
limited habitat features rather than food supply (Behnke 1992). Trout
require four kinds of habitat during the various stages of their life
history: spawning habitat, nursery or rearing habitat, adult habitat,
and overwintering habitat. Deficiencies in any one of the four will
limit the potential production.
Spawning
Habitats/Occurrence: All
western trout spawn during the spring, stimulated by the rising water
temperatures (Behnke 1992). However, specific spawning time varies
greatly depending on temperature and flow regimes.
Klamath
River
redband
trout spawn from late February through May (City of Klamath Falls 1986).
Although
some spawning habitat is found in the bypass reach, the wild and scenic
river segment of the upper
Klamath
River
and
the
California
reach
have little or no spawning habitat for trout (ODFW 1997; City of Klamath
Falls 1986).
Recruitment
of spawning gravel to the wild and scenic river segment, as well as the
Bypass and
California
reaches,
is very limited, due to the presence of the J.C. Boyle Dam and the small
number of tributary streams (City of Klamath Falls 1986).
Of
the spawning habitat that is present in the wild and scenic river
segment of the upper
Klamath
River
,
much would be exposed during low flows, as a result of peaking
operations, making these areas unsuitable for incubation of trout
embryos during most years. The abnormal flow fluctuations, associated
with peaking operation below the powerhouse, may also interfere with
normal spawning behavior (Marcus et al. 1990).
Adult
trout from the analysis area are assumed to migrate to either
Spencer
Creek
or
Shovel Creek to spawn due to the general lack of spawning habitat in the
Klamath
River
.
Spencer
Creek,
the primary spawning tributary in the Keno reach of the river, empties
into J.C. Boyle Reservoir. The spawning population in
Spencer
Creek
has
been monitored in
Spencer
Creek
and
robust spawning recruitment is evident (ODFW 1995).
(pg
89)
However,
most of the spawners in
Spencer
Creek
appear
to come from the Keno reach above J.C. Boyle Dam.
The
number of fish below J.C. Boyle Dam attempting to migrate to Spencer
Creek
apparently
has decreased by about 99 percent since the construction of the J.C.
Boyle facility (Hemmingsen et al. 1992). Monitoring migration over J.C.
Boyle Dam in 1959 indicated 5,529 adult redband passing the facility,
while counts in 1991 (a drought year) were only 70.
River flow in the mainstem reach used by this population is
highly regulated (ODFW 1995) and may be affecting fishery ecology
(Marcus et al. 1990). Inadequate upstream fish passage facilities at
J.C. Boyle Dam are also a possible cause of this decline.
Shovel
Creek, located three miles downstream from the state line, is the
primary tributary to the Klamath River
reach
below the wild and scenic river segment of the upper
Klamath
River. The lower 2.77 miles
of this tributary are an important spawning area for the
Klamath
River
wild
redband trout (CDFG 2000). However, insufficient spawning gravel was
found to be a limiting factor in Shovel Creek. Loss of gravel storage
areas, increased fine sediment contributions, and diversions for
irrigation delivery may also be impairing spawning habitat quality.
Adults were documented to be moving upstream into Shovel Creek to spawn
from March-June (Beyer 1984). Most downstream movement of spawned out
adults (kelts) occurred from mid-May until June.
Rearing
Habitats/Occurrence: Important
rearing habitat for trout would include habitat with protective cover
and low velocity water (Behnke 1992). Such habitats occur along the
margins of streams and in spring seeps, side channels, and small
tributaries. The bypass reach of the river is potentially an important
rearing area for young trout during their first year of life (City of
Klamath Falls 1986). After the high winter/spring flows drop off, the
flow is relatively stable in bypass reach from summer through winter and
the water temperatures of the lower part of the reach is improved by
spring inflow (USDI-BLM 1990).
Little
information exists on the condition of rearing habitat in upper wild and
scenic river segment of the upper Klamath River, however the milder
gradient of the upper reach should provide more rearing habitat than the
lower segment. In the lower wild and scenic river segment of the upper
Klamath
River
very
few pools or backwater habitats suitable for rearing of juvenile fishes
were found under summer low flow conditions even less would be available
at higher flows due to increased water velocities in the narrow,
constricted river valley (City of Klamath Falls 1986).
Some
rearing habitat for trout fry and juveniles is available in the
California
section
of the
Klamath
River
.
Shovel creek is considered an important rearing tributary to the
Klamath
River
in
California
(CDFG
2000). Shovel Creek rearing capacity could be limited as a result of
water withdrawal (Beyer 1984). However, the effect of diversions on
age-0 fish rearing habitat is uncertain.
In
the wild and scenic river segment of the upper Klamath River and
California reach, large expanses of riverbed are exposed and inundated
on a daily basis throughout varying lengths of the year (particularly
during the summer) due to the water level fluctuations associated with
hydropower generation. The dewatering of river habitat on a daily basis
contributes to reductions in the availability of rearing habitat (Marcus
et. al. 1990). In addition, stranding of rearing fish may also occur in
the wild and scenic river segment of the upper
Klamath
River
as
a result swift exposure of riverbed. Stranding has been documented in
the California
reach,
below wild and scenic river segment (City of Klamath Falls 1987). The
target species for this stranding study was larval suckers, however the
exact species classification of stranded animals was not noted as all
fish were classified as larvae.
Fry
and juvenile redband trout inhabit the wild and scenic river segment of
the upper
Klamath
River
.
Monitoring by PacifiCorp, snorkeling of the J.C. Boyle reach in 1996,
indicated the presence of young of the year (less than three inches)
redband trout (ODFW 1997). Juvenile (pg
90) trout appear to rear as a relatively larger percentage of the
population in the Bypass reach versus the portions of the wild and
scenic river segment of the upper Klamath River and California reach
(City of Klamath Falls 1986). Trout fry and juveniles were observed in
the
Klamath
River
below
Shovel Creek during electro-fishing surveys in September 1984. In Shovel
Creek fry emergence occurred in June. Fish averaged 29 mm long and grew
about 15.7 mm every month until November (Beyer 1984). Most trout
emigrated from Shovel Creek to the
Klamath
River
as
young of the year (CDFG 2000).
Fry
and juvenile trout appear to exhibit a late summer to early fall
downstream movement at the J.C. Boyle Dam (City of Klamath Falls 1986).
Observed downstream movement of fry to the J.C. Boyle Reservoir of the
Klamath River
from
Spencer
Creek
occurred
during October and November (Hemmingsen et al. 1992).
Some
fry movement occurred as early as May and June. Research monitoring
downstream fish movement below J.C. Boyle Dam to measure possible
recruitment from
Spencer
Creek
concluded
that the low numbers of juvenile redband collected suggests inadequate
recruitment was occurring to maintain the population in the river
between the J.C. Boyle Dam and the California
state
line (Hemmingsen et al. 1992).
Other
sources of recruitment for trout may contribute to the present fishery,
including the upper basin sources, mainstem sources, and tributaries
sources such as Shovel Creek. In Shovel Creek, movement of fry (0+)
occurred in late summer with the peak in late August, and juveniles (1+)
migrated out of Shovel Creek to the river from April to June (Beyer
1984).
Adult
Habitats/Occurrence: At
adulthood, stream species generally live at a depth of 0.3 meters or
greater, in areas where slow waters for resting are juxtaposed with fast
waters that carry food, and where protective cover is provided by
boulders, logs, overhanging vegetation, or undercut banks (Behnke 1992).
Cover
for adult habitat in the
Klamath
River
is
primarily derived from instream sources such as boulders and water
depths (City of Klamath Falls 1986). The riparian vegetation
contribution to cover varies in along the length of the river. Large
expanses of riverbed in the wild and scenic river segment of the upper
Klamath River are exposed and inundated on a daily basis throughout
varying lengths of the year (particularly during the summer) due to the
water level fluctuations associated with hydropower generation.
ODFW’s
monitoring of downstream fish movement below J.C. Boyle Dam indicated
that
Spencer
Creek
did
not have adequate recruitment of juvenile redband to maintain the adult
population in the river between the J.C. Boyle Dam and the
California
state
line (Hemmingsen et al. 1992). Regardless, the existing trout population
appears to support a sustainable fishery (ODFW 1997). Estimates of adult
trout (197 mm or larger) populations between J.C. Boyle Powerhouse and
the Frain Ranch (upper reach), and Frain Ranch to Salt
Caves
(lower
reach) were conducted in August 1984 (City of Klamath Falls 1986).
Population estimates ranged from 890 fish/mile in the upper reach
(95 percent confidence interval of 763-1,069), to 1,911 fish/mile in the
lower reach (95 percent confidence interval of 475-7,936). The highest
number of adult trout would probably have occurred late in January or
early February.
Shovel
Creek appears to support a healthy population of spawning rainbow trout
(CDFG 2000). The age of the Shovel Creek fish at maturity was similar to
rainbow trout in other studies (Beyer 1984). Most trout mature in their
second or third year. Minimum size at maturity 140 mm (males) to 163 mm
(females) was smaller when compared to other studies but within the
range of normal variation. The back calculated mean fork-length for each
age of fish taken in Shovel Creek was; 102 mm age 1, 191 mm age 2, 293
mm age 3, and 357 mm at age 4.

91)Redband management: The
planning area portion of the Klamath River in Oregon is managed as a
catch-and-release fishery from June to September, and is open to a
limited catch the remainder of the year (ODFW 2002). The palatability of
the trout meat decreases during the summer/fall seasons, potentially as
a result of the poor water quality conditions (ODFW 1997). ODFW noted
that in the lower river reach downstream of the J.C. Boyle Powerhouse
the hydroelectric peaking operation seriously hampered angler use and
catch rates. Low angler use was noted during power peaking periods due
to added difficulty and poor success during those conditions.
In
the
California
reach
of the planning area, Shovel Creek is closed to fishing year-round to
protect important wild trout spawning areas, and a portion of the
Klamath
River
,
250 feet upstream and downstream from the mouth of Shovel Creek, is
closed from November through June (CDFG 2000). Otherwise the
California
segment
is open to a limited catch from April to November. When compared to
other wild trout rivers monitored by California Department of Fish and
Game, the Upper Klamath River Wild Trout Area had the highest overall
catch
rate (CDFG 2000).
Lost River and Shortnose Suckers (pg 91)
“The
Lost
River
sucker,
or “mullet,” once an important food staple for local Native
Americans, was at one time abundant in
Klamath
Basin
lakes
and streams, migrating by the thousands to spawn in tributaries of
Upper
Klamath Lake. Lost River and shortnose suckers typically inhabit lakes
and migrate into tributaries to spawn. Adult suckers are long-lived with
late sexual maturity (ages 5-7). There is extremely poor recruitment to
adult size and age classes in the
Klamath
Basin
.
Recruitment failure is attributed to poor survival of larval and
juvenile life history stages due to water quality changes, habitat
availability, and exotic predation (ODFW 1995; Desjardins and Markle
2000).
Spawning
Habitat/Occurrence: For
stream spawning populations, suckers begin their spawning migration in
late February, March, or early April, depending on peak flows, with
spawning activity continuing well into May (USDI-USFWS 1993). Suckers
spawn in a range of water temperatures (9-17 degrees Celsius), water
depths (1-170 centimeters), and water velocities (42-132
centimeters/second) (Beuttner and Scoppettone 1990). Spawning occurs
near the bottom, and when gravel is available eggs are dispersed within
the top several centimeters. Spawning over cobbles and armored
substrate, eggs fall between the crevices or are swept downstream.
Spawning preference appears to be more related to flow than to substrate
type. However, reproductive success may not be tightly linked to
spawning habitat preference.
Spawning
runs of listed sucker species has been documented in the
California
reach
above Copco Reservoir (Beuttner and Scoppettone 1991.
Tagged
suckers have been documented appearing to prepare for spawning near the
slackwater of Copco Reservoir (City of Klamath Falls 1987). Suckers have
not been observed spawning in Shovel Creek. Age class analysis has
indicated that successful recruitment is not occurring among the two
sucker species in these segments of the river (Beuttner and Scoppettone
1991). The scouring and
dewatering associate with the hydroelectric operations were thought to
reduce survival of eggs and larvae, and predation may also be impairing
recruitment.
Rearing
Fry/Juvenile Habitat/Occurrence: Larval
suckers usually spend relatively little time in tributary streams but
migrate back to the reservoir shortly after swim-up (the emergence of
larvae from spawn substrate, which typically occurs soon after hatching
in suckers) (USDI-USFWS 1993). Larval suckers appear to exhibit a diel
migratory behavior and typically migrate during the evening hours. Most
larvae would likely migrate to the reservoir between May and June.
Larvae prefer slow water areas surrounded by rooted aquatic vegetation,
and the larvae appear to avoid areas devoid of vegetation. Gently
sloping, unvegetated shorelines are common today lining the lakes and
larger streams of the Klamath.
(pg
92) This
type of habitat was probably nonexistent historically and created as a
result of dams. This type
of habitat does not provide nursery habitats of the same quality as a
marsh/mature riparian edge habitat.
Little
is known of juvenile sucker habitat in the wild and scenic river segment
of the upper Klamath River, the adjacent river reaches, and the
slackwater of Copco Reservoir. However, juvenile habitat could be
affected by water level fluctuation from power peaking operations, which
can disturb littoral zone cover and substrate, and can also affect
nutrient concentrations, light, temperature, phytoplankton and
zooplankton abundance, and macroinvertebrates (Desjardins and Markle
1999).
Loss
or alteration of any of these components could be harmful to sucker
population stability. Introduction
of exotic fish species and hybridization have also been suggested as
mechanisms for decline. Recent genetic work suggests hybridization does
not occur frequently. Surveys for larval suckers in the
California
reach
indicated that the majority (98 percent) of larvae occurred near the
lower most portion of the reach (City of Klamath Falls 1987). Larval
presence declined substantially progressing upstream.
Adult
Habitat/Occurrence Copco Reservoir:
Lost
River and shortnose sucker extended their range into the upper
Klamath
River
system
following the creation of lacustrine habitat by construction of Copco
reservoir (City of Klamath Falls 1987). Adult suckers spend relatively
little time in the riverine spawning reaches, migrating back to the
reservoirs after spawning (USDI-USFWS 1993).
The
Klamath
River
reservoirs
may be acting as catch basins for expatriated suckers from Upper Klamath
Lake
(Desjardins
and Markle 2000). Juveniles and subadult survive in J.C. Boyle
Reservoir, while older individuals move downstream through the Bypass
reach, the wild and scenic river segment of the upper
Klamath
River
,
and the
California
reach
to Copco and Iron Gate Reservoirs.
Introduced
Species (pg 92)
At
least fourteen exotic species occur in the river and reservoirs (Table
2-21). Yellow perch, fathead minnows, Sacramento
perch,
and golden shiner typically favor slower water habitats including
slackwater shoals close to Copco Reservoir, and generally are not found
in swift flowing portions of the river (USDI-BLM 1990). Although not
documented by fisheries specialists, there have been at least two
reports of white sturgeon in the planning area. White sturgeon was
planted in
Upper
Klamath Lake
in
1956 (ODFW 1997). Brown trout, planted in Copco Reservoir, inhabit and
migrate through the
California
reach
to spawn in Shovel Creek (CDFG 2000). Steelhead, planted into Copco
Reservoir 1971-1981 (excepting 1975, 1977, and 1978) has been reported
from the
California
portion
of the Klamath in the past.
Limitation to Aquatic Species in the Wild and
Scenic
River
Habitat:
Abnormal
fluctuation in daily and seasonal flow patterns created below the
hydroelectric power operations can lead to low flow dewatering of
spawning beds, and both low flow and high flow induced spawning
interference, incubation mortality, and rearing mortality of resident
fish (Marcus et al. 1990).
Downstream
dewatering and desiccation of spawning habitat is a documented
occurrence in the wild and scenic river segment of the upper
Klamath
River
(City
of Klamath Falls 1986). Downstream
dewatering and desiccation are undoubtedly the worst of the possible
adverse impacts on the stream (Marcus et al. 1990). In addition, in
regulated streams where natural peak flushing flows are greatly reduced,
fine sediment can accumulate in the deeper layers, clogging the free
flow of water (Marcus et al 1990).
(pg
93)
The quality of the spawning habitat present in the wild and
scenic river segment of the upper
Klamath
River
was
impaired, as result of being heavily embedded and interspersed with
large cobble (City of Klamath Falls 1986). Embedded sediments can
adversely affect the intragravel habitat important to the survival of
benthic insects, incubating eggs, and rearing larvae (Marcus et al.
1990).
The
wild and scenic river segment of the upper Klamath River
is
probably poor rearing habitat. This can be attributed to high gradient
and a wide range of flow velocities as a result of peaking operations by
the J.C. Boyle Powerhouse. Downstream dewatering of habitat resulting
from hydroelectric impoundments would eliminate access to cover habitat
and potentially degrade the quality of the existing habitat (Marcus et
al. 1990).
Alteration
of instream flows from power operation and changes in sediment regimes
due to reservoirs can result in decreased bank stability and loss of
riparian vegetation (Marcus et al. 1990), which would decrease the cover
habitat important to rearing fish (Behnke 1992).
Rearing
habitat in the
California
reaches
would be affected similarly by peaking operations.
The extent and cumulative impacts of stranding has not been
studied in the wild and scenic river segment of the upper Klamath
River
(CDFG
2000), but the occurrence of larval stranding has been documented (City
of Klamath Falls 1987). In the wild and scenic river segment of the
upper Klamath River and California reach, large expanses of riverbed are
exposed and inundated on a daily basis throughout varying lengths of the
year (particularly during the summer) due to the water level
fluctuations associated with hydropower generation (City of Klamath
Falls 1986).
The
predominate habitat types, from the lower segment of the upper reach
within the wild and scenic river segment of the upper Klamath River, are
shallow rapids, riffles, and runs. Channels with an abundance of shallow
habitat are more likely to have larger areas exposed during down-ramping
where fish could become separated from the main river flow due to
declines in stage (
Stillwater
1999). The large flow
fluctuations associated with the J.C. Boyle Powerhouse can cause high
mortality to young fish through stranding (City of Klamath Falls 1990).
Daily
temperature fluctuations of up to 12 degrees Celsius occur in this full
flow reach of the river during the middle of the summer (City of Klamath
Falls 1986). The effects of these large diurnal temperature fluctuations
on the existing cold water fish populations has not been studied
specifically for the wild and scenic river segment of the upper Klamath
River.
It
can be assumed that water temperature fluctuation impacts to fisheries
may include elevation of temperatures beyond the range preferred for
rearing, inhibition of upstream migration of adults, increased
susceptibility to disease, reduced metabolic efficiency, and shifts in
competitive advantage (Hicks et al. 1991).
Impacts
to other aquatic resources may also be occurring as a result of
hydroelectric power operations, including water level fluctuation
associated with J.C. Boyle Powerhouse, and poor passage. The
distribution of benthic organisms appears to be limited by power peaking
operations (City of Klamath Falls 1986). The production of benthic
invertebrates’ appears to be limited to locations in the riverbed that
remained wet during the low flow period of the daily flow cycle.
The
impact of J.C. Boyle Dam impairing downstream movement of fish to the
wild and scenic river segment of the upper
Klamath
River
has
not been studied. Studies of trout food habits in the Bypass reach and
wild and scenic river segment of the upper Klamath River
did
not note the occurrence of prey fish species in stomach contents
analysis (City of Klamath Falls 1990).
Downstream
passage concerns have been noted, including poor passage hydraulics and
predation exposure in the forebay of J.C. Boyle Reservoir (FishPro
2000), which may limit the downstream movement of prey species.
(pg
94) Redband Trout: ODFW
fisheries biologists have noted that redband in the wild and scenic
river segment of the upper
Klamath
River
and
Bypass reach appear to be smaller in size on average than fish observed
in the Keno reach of the river above J.C. Boyle Reservoir (Smith 2000,
personal communication). The physical structures of Keno Dam are more
conducive to fish passage than J.C. Boyle (FishPro 2000).
Lake
elevation
and flow rates are regulated at Keno Dam to maintain near constant
conditions in
Lake
Ewauna
(FishPro
2000) and instream flows for the reach generally are governed by Bureau
of Reclamation directives in meeting their instream flow requirements
downstream from Iron Gate Dam (PacifiCorp 2000). This results in fairly
unimpaired flows in the Keno reach.
Adult
habitat limits the population biomass of resident trout in most streams
(Behnke 1992). Spawning and
rearing habitat are adequate, and the food supply would support a
greater biomass of trout if more adult habitat were present. Excessive
recruitment into the population, where young and adult fish are
competing for a common food supply, results in short-lived slow-growing
individuals and a population whose biomass is tied up in small, young
fish.
Based
on the population estimates and length frequency distribution (City of
Klamath Falls 1986) and the existing conditions of poor upstream passage
at J. C. Boyle Dam (Hemmingsen et al. 1992) and power operations which
provides suitable habitat to only individuals which can escape the daily
dewatering, the trout population could be exceeding carrying capacity
and the additive recruitment of trout to these segments could then
affect the trout size/age structure.
Genetics
may be playing a part in the differences in size and age between the
Keno stretch and the wild and scenic river segment of the upper
Klamath
River
reach.
The populations of Upper
Klamath
Basin
trout
exhibit older ages at maturity and large maximum size (Behnke 1992).
Fish passage facilities at J.C. Boyle Dam have been described as
inadequate (FishPro 2000; Hemmingsen et al. 1992). Recruitment to the
wild and scenic river segment of the upper Klamath River
may
be limited from these upper populations.
Movement
between Keno and the upper basin may not be similarly affected.
Selection of smaller, earlier maturing fish may be occurring in the wild
and scenic river segment of the upper Klamath
River
.
Food
supply may also be impairing size and age structures. Trout restricted
to small food items form populations characterized by small maximum
individual sizes and young maximum ages (Behnke 1992). Only when trout
have adequate access to larger prey, such as crayfish and fish, can they
avoid feeding competition with smaller trout and sustain growth.
Truncated
population structures, particularly in the Bypass reach where older age
classes were missing, has been documented (City of Klamath Falls 1990).
Downstream
passage concerns have been noted, including poor passage hydraulics and
predation exposure in the forebay of J.C. Boyle Reservoir (FishPro
2000), which may limit the downstream movement of larger prey species.
Lack of this larger fish prey base could be limiting the size classes
present in the wild and scenic river segment of the upper
Klamath
River
,
which would not occur in Keno Reservoir (which has better passage).
Historic Anadromous Species
The
steelhead life history morphology was historically present in this
group, but is now considered extinct (ODFW 1995). This life history
probably was introduced into the
Upper
Klamath
Basin
after
the Pleistocene Lake Modoc opened to the
Pacific
Ocean
(Behnke
1992).
The
novel traits in the Upper
Klamath
Basin
group
may have resulted from the interbreeding of the new invading O.
mykiss with
the original resident fish of the basin (ODFW 1995; Behnke 1992).
Steelhead were documented as far up as the
Link
River
(ODFW
1997).
Fall
chinook and spring chinook salmon potentially spawned within the
Sprague
River
(Klamath
River Basin Fisheries Task Force 1992). Runs were seen as far up the
Sprague
River
as
Beatty, Oregon, and spawning was reported in the North and South Forks
of the Sprague. Historically, entry timing for spring chinook appeared
to occur in March to upper
Klamath
River
area.
Fall chinook entry to the Sprague
River
was
noted in September and October.
The
Coho adapted to the
Upper
Klamath
Basin
had
been lost sometime prior to the earliest documented fisheries assessment
and collections, and prior to fish collections between 1914-1918 at
Klamathon Racks (Klamath River Basin Fisheries Task Force 1992).
Currently
the Southern Oregon Northern California Coastal Coho salmon ESU, in
which the Klamath River populations downstream of Iron Gate Dam are
included, was listed as threatened under the Endangered
Species Act in
1997 (62 FR 24588). An ESU or Evolutionarily Sensitive Unit, is a
designation that defines a distinctive group of Pacific salmon,
steelhead, or sea-run cut-throat trout (NOAA and National Marine
Fisheries Service 2000).
Designated
critical habitat for Southern Oregon Northern California Coastal Coho
salmon occurs downstream of Iron Gate Dam (May 5, 1999; 64 FR 24049).
Reintroduction
of anadromous fisheries to the
Upper
Klamath
Basin
has
been addressed more than once (Fortune et al. 1966; Klamath River Basin
Fisheries Task Force 1992). Conditions of the Upper
Basin
and
anticipated relative costs versus relative benefits negated
implementation of reintroduction of anadromous fisheries at the time
based on these reviews.
The
hydroelectric project on the upper Klamath River
(FERC
Project No. 2082), including five of the six mainstem dams currently
blocking or impairing fish passage, will be assessed for reintroduction
of anadromous species through the hydroelectric facilities as part of
the relicensing process.
Management of the Fishery Resources (pg95)
The
BLM has committed to fisheries management goals from the 1994
“Northwest Forest Plan” and included Aquatic Conservation Strategy
objectives, “Bring Back The Natives,” and “Fish and Wildlife
2000.” These plans/initiatives are guidance to the BLM for fisheries
habitat management.
“Bring
Back The Natives” is a national effort by the BLM, the USFS, and
National Oceanic and Atmospheric Administration-Native Marine Fisheries
Service to restore the health of entire riverine systems and their
native species (NFWF et al. 1992).
Public
land management initiatives, such as “Fish and Wildlife 2000,”
target key habitats and animal and plant species as well as water
quality. “Fish and Wildlife 2000” is a plan to improve management of
fish, wildlife, and their habitats on BLM-administered lands.
It
is the objective of the BLM to manage and maintain habitat in the
planning area and, where feasible, restore those habitats that are now
in degraded condition. The 1994 “Northwest Forest Plan” provides for
protection of areas that could contribute to the recovery of fish and
improve aquatic habitat and water quality through out the basin. The
1994 “Northwest Forest Plan” also provides general guidance on
implementation and effectiveness monitoring.
Federal
aquatic habitat within western Oregon, Washington, and northern
California
falls
under the 1994 “Northwest Forest Plan” guidance and aquatic
conservation strategy objectives, which include:
•
Establish watershed and riparian goals and objectives to maintain and
restore fish habitat;
•
Delineate riparian management areas and a system of key watersheds to
protect fish habitat;
•
Provide standards and guides for management in riparian areas; and
•
Calls for watershed analysis and sub basin reviews to set priorities and
provide guidance on priorities for watershed restoration.
Description
of Potential Area of Critical Environmental (pg 104)
Concern Values
An
ACEC designation highlights an area where BLM special management
attention is needed to protect and prevent irreparable damage to
important historic, cultural, and scenic values; fish or wildlife
resources; or other natural systems or processes; or to protect human
life and safety from natural hazards (BLM Regulations, 43 CFR 1610).
The
ACEC designation indicates to the public that the BLM not only
recognizes the area possesses significant values, but has also
established special management measures to protect those values.
Designation serves as a reminder that the significant values or
resources must be accommodated during the BLM’s consideration of
subsequent management actions and land use proposals within an ACEC.
To
be considered as a potential ACEC, and further analyzed in resource
management plan alternatives, inventory data for the area must be
analyzed to determine whether there are areas containing significant
resources, values, systems or processes, or hazards. To be a potential
ACEC, an area must meet both relevance and importance criteria, as
established and defined in BLM Regulations, 43 CFR 1610.7-2:
Relevance.
There
shall be present significant historic, cultural, or scenic values; a
fish or wildlife resource or other natural system or process; or natural
hazard.
Importance.
The
above described value, resource, system, process, or hazard shall have
substantial significance and values. This generally requires qualities
of more than local significance and special worth, consequence, meaning,
distinctiveness, or cause for concern.
A natural hazard can be important if it is a significant threat
to human life or property.”
Upper
Klamath River
Area
of Critical Environmental Concern Designation (pg 106)
The
“Klamath Falls Resource Area Record of Decision and Resource Area
Management Plan” (1995) designated an ACEC in the Klamath River Canyon
from rim to rim extending from J.C. Boyle Powerhouse to the
Oregon/California state line (see Map 2).
The
presence of cultural (both prehistoric and Native American traditional
use) values, scenic values, fish and wildlife (both populations and
habitat) resources, and a natural process or system (both priority plant
species and vegetation) were found to be both relevant and important.
Management
guidance outlined in the 1995 resource management plan specified that
this area is not available for planned timber harvest, limited
off-highway vehicle use to designated roads, allowed no developments to
enhance the potential for grazing, limited mineral leasing to no surface
occupancy, and allowed no hydroelectric development. The area was to be
managed for semi-primitive motorized recreation opportunities. A
site-specific management plan for this ACEC will be developed as part of
the final river plan.
Potential
Areas of Critical Environmental Concern
This
plan will also evaluate extending the existing ACEC to Segment 1 (below
J.C. Boyle Dam to the powerhouse) of the planning area. To be considered
as a potential ACEC, an analysis and evaluation report must consider the
relevance and importance of resource values identified within the area
which has be nominated as an ACEC. This report is found in Appendix I.
