Study
puts steelhead back in Squaw Creek
Steelhead may swim again in Squaw
Creek in 10 years.
That is one of the major goals
of the "Back to Home Waters" project spearheaded by the Deschutes Basin
Land Trust.
According to trust project
manager Brad Nye, Back to Home Waters is "an attempt to identify what
the habitat needs are to reintroduce anadromous fish into the upper (Deschutes)
Basin."
Portland General Electric
(PGE) and the Confederated Tribes of Warm Springs are critical players
in the fate of fish in the upper basin. Those two entities, who are seeking
dam relicensing together, will be responsible for fish passage around
dams on the Deschutes.
Last month, PGE released some
300 one-year-old steelhead into Squaw Creek at the Deschutes Basin Land
Trust's Camp Polk Meadow Preserve.
Biologists will monitor the
fish to learn more about their migratory behavior.
According to Nye, experiments
with fish migrating back to sea have shown fish have a hard time getting
through Lake Billy Chinook because a mix of currents from three rivers
"basically confused the fish."
PGE and the Tribes are working
on modifying currents in Lake Billy Chinook to help out-going fish make
it to collection points where they can be transported into the lower river.
The project is technically
difficult and expensive, but all the players seem eager to make it work.
"There's a pretty strong commitment
to make that happen," Nye said. "I think there is a lot of momentum."
While PGE and the Tribes work
out relicensing and current modification, the Deschutes Basin Land Trust
will continue working on what Nye calls its "bread and butter issues."
As studies continue, the trust
will prioritize actions needed to make the streams hospitable for fish.
That may mean conservation easements, working with land owners on habitat
restorations, or, in exceptional cases, acquiring land along streams.
Besides the trust, Back to
Home Waters involves local governments and a variety of state and federal
agencies that have an interest in restoring fish runs.
Those interests are not strictly
environmental, Nye pointed out.
"We think there's some economic
benefit to the community from having these fish back," Nye said.
Steelhead were played out
in Squaw Creek by 1961-62, Nye said. The damming of the Deschutes River
was the major factor in bringing an end to the runs, but steelhead populations
were apparently in decline before the dams were built.
Water withdrawal for irrigation
may have degraded habitat.
"It's likely those factors
contributed to the demise of steelhead runs," Nye said.
As landowners and conservationists
work to restore habitat and return water to the creek and as utilities
work to improve fish passage, the return of steelhead in Squaw Creek is
in sight -- a ways down the road.
"I would guess that steelhead
will be back in Squaw Creek in 10 years," Nye said. "It could be longer
than that; it's probably not going to be a lot shorter than that."
