Human actions can and do threaten the clean, healthy and cool
water salmon need to survive, so improving stream habitat is a
key component of LCFEG's mission.
Project Highlight: Hamilton Creek
restoration efforts, lower Hamilton Creek contained a uniform,
single thread channel lacking any defining habitat features to
scour pools, sort spawning gravels or refuge areas for young
juvenile salmon. Since 2005, the LCFEG has received support by
SRFB, BPA, and WDFW to place hundreds of logs, create multiple
side channels and expand groundwater-fed chum spawning. Since
the 2011 restoration of the Hamilton Springs chum channel, we
have seen a huge increase in chum usage and observed spawning
throughout the entire groundwater fed channel.
Creek’s main stem has received habitat complexity treatments
with the placement of hundreds of logs and the construction of
logjams. This once ‘featureless’ 4,500 foot reach of Hamilton
Creek is now filled with numerous logjams, side channel
complexity and groundwater fed spawning habitat benefiting
ESA-listed threatened populations of Lower Columbia River chum,
winter steelhead, Chinook and Coho.
Project Highlight: Lee Fish Passage Project
The Lee fish passage project site was located on Mason Creek
which empties into the East Fork Lewis River. A 6-ft round
corrugated culvert at the private road creek crossing
periodically restricted passage for populations of Coho and
Steelhead juveniles. The landowners repeatedly encountered
issues each spring when the undersized culvert mouth would plug
with debris and over topped the roadway.
After being surveyed a
design was created to replace the culvert with a 50’ x 12’
prefabricated steel bridge. LCFEG worked closely with the
utility district during the project to ensure water, electrical
and telephone lines routed beneath the stream bed were not
damaged or disturbed and despite the extra processes required
the project didn’t suffer delays. Post construction, fish
passage has been restored to 4.6 miles of Mason Creek,
critically important to native Steelhead and Coho populations.
