Upper Basin to feel greatest
impact
Pumps may be shut off
during low water years
Even if
the final determination is only a shadow of
the proposed order, irrigation in the Upper
Basin would change dramatically: those
irrigators will face limitations akin to
those Klamath Reclamation Project irrigators
have been grappling with for years.
The
Tribes, with their beginning-of-time
priority date, could call their water rights
to keep the minimum water flows a judge
agreed are necessary to maintain their fish
and wildlife habitats.
To
achieve flows,
pumps
feeding junior water rights are shut down
until the senior water right is met.
Not only
that, Oregon Water Resources before the
order could not enforce water rights being
adjudicated so Upper Basin irrigators with
senior water rights could not call their
right, leaving junior water right holders
the ability to pump freely.
“Water
right holders upstream, because there are
very few areas adjudicated up there … have
had the ability to divert what they need to
satisfy what their right says,” said Tom
Paul, deputy director of Oregon Water
Resources Department.
Larry
Dunsmoor, who works on the Sprague River,
said unlimited use is evident.
“In the
middle of the summer when it gets hot and
everybody starts to irrigate, the river just
drops,” he said. “With the proposed order,
flows would change that.”
Flows
confirmed in adjudication are subject to a
slew of variables — water year, habitat,
reach of water, etc.
But in
short, the range of f lows in the Tribes’
water right is higher than what has
historically remained in the rivers and
streams after irrigation.
Several
contestants
contacted by the Herald and News would not
comment on adjudication, citing lack of
knowledge in the proceedings, including
Roger Nicholson, the rancher behind Water
For Life Inc., who has long been active in
the process.
In a
press release announcing the adjudication
decision, the Klamath Tribes said, “Some
interests in the Basin advised people that
the Tribes’ water rights are minimal, but
those interests have been proven wrong.
People who followed that advice have
obviously been misled in a situation where
they are risking a lot.”
Bill
Ganong, an attorney
for
irrigation districts involved in
adjudication, agreed, saying there’s no
doubt the confirmed f lows will affect
irrigators upstream of Upper Klamath Lake.
The
farther upstream they are, the less water
they’ll have if the Tribes call their water
right.
“… It is
clear,” Ganong said, “that for some stream
segments, especially in the Sprague River
drainage, the enforcement of Tribal rights
in the amounts provided in the proposed
orders would have a profound impact on the
use of surface water for irrigation.”
Historical data on river
flows
Recently confirmed Tribal water rights would
require more water to remain in streams and
rivers from which Upper Basin irrigators
draw water.
The
U.S. Geological Survey tracks flows on water
bodies, including minimum daily flows, which
vary with the amount of water in the rivers
or stream. Here is a sample of,
historically, the highest minimum flow
recorded for a month, lowest minimum flow
recorded for a month, and proposed order's
minimums.
