of the U.S. Fish and Wildlife Service and the Wingwatchers club toured
the test area earlier in the week and were happy with results.
“So
far it doesn’t look like we’ve had any big erosion,” said Bill
Wood of Wingwatchers.
The
underwater berm was installed on a 120-yard section of the west
shoreline. The idea was to reduce wave action that is cutting the
shoreline away.
With
the small success as encouragement, the next step will be to treat much
more of the shore. The process, tentatively scheduled for fall, will
include building rock jetties perpendicular from the shore to further
reduce waves.
“Those
fingers really do dissipate the wave activity,” said Sue Mattenberger,
a hydrologist with the Fish and Wildlife Service.

In
addition, trees such as alder, willow and dogwood will be planted to
provide root structure. Those planted in past years are already taking
hold, protected from hungry animals by wire cages.
The
long-term goal is to create wetlands between the berm and shoreline to
stabilize soils and reduce sediment. The process also could deter
animals such as marmots which have burrowed into the shore, allowing
water to wash up underneath the ground surface.
Between
$25,000 and $30,000 has been spent on the project so far, Mattenberger
said. That includes planning and permitting costs, and reinforcement of
a dirt road to allow excavators to reach the water and drop rocks.
The
money was provided by Fish and Wildlife Service and the Oregon Watershed
Enhancement Board.
Other partners in the restoration project, besides Wingwatchers, are the U.S. Bureau of Reclamation and the Klamath Watershed Council.
Mattenberger
noted their contributions, as well as donated rock from the Running Y
Ranch.
“There
are a lot of partners coming together collaboratively to work on a
problem in the Basin,” she said.
