2005 LCFEG Projects
Lower Washougal River Restoration Project
Located along the lower end of the Washougal River (RM
0-1) within the Salmon-Washougal Watershed (WRIA 28), this
tidally-influenced reach exhibits a severe lack of habitat
complexity (boulders, woody debris, & native plants)
and high summer water temperatures resulting from past and
present human impacts. On-site construction activities
scheduled for this summer include: 1) the connection of
isolated habitats by increasing access to side channels,
oxbows, and other channels necessary for salmon spawning
and rearing; 2) installing two large riffles for
restoration of the pre-1935 river channel; and 3)
rehabilitating three abandoned gravel quarries to provide
functional fish habitat and to increase sediment transport
functions, water storage capacity, and historic spawning
gravel supply. LCFEG also hopes to return a healthy
riparian canopy to this site by acquiring funds to
schedule volunteer riparian plantings this winter.
Plantings would reduce water temperatures and increase
both shelter and food supply for
fish. Project partners include the City of Camas,
Georgia-Pacific (GP), Burlington Northern-Santa Fe
Railroad (BNSF) and WADNR.
Upper Washougal River Restoration Project
The first phase of this three-year project includes
data collection, material stockpiling, and placement of at
least five (5) pre-designed and bedrock-secured logjams
into three tributary reaches (Stebbins & Reeder
Creeks) along the upper five miles of the Washougal River
(beginning at the Washougal Salmon Hatchery in Skamania
County). The project addresses habitat impacts resulting
from historic forest fires, timber practices, and
management decisions resulting in the removal of large
wood from the active stream channel. Project activities
will restore stream bed substrate, reduce water
temperatures, and increase channel diversity for fish. Activities
will also restore access to nearby tributaries, increase
long-term aquatic productivity, and create suitable
spawning and rearing habitat for Washougal River salmon
and steelhead runs.
Indian Mary Creek Restoration
LCFEG will replace two 48" culverts impassable to
fish on Indian Mary Creek, 150 feet upstream from Franz
Lake along the Columbia River Gorge. These culverts will
be replaced with either a single 12' diameter arch pipe or
a rail road car bridge on a private driveway at the east
end of Franz Lake in Skamania County. Indian Mary Creek is
one of the few remaining Gorge tributaries with high
year-round flows and spawning or rearing utilization by
multiple fish species including chum, coho, Chinook,
steelhead, and cutthroat trout. Restoration will restore
access to 3,500 feet of stream channel and over 15 acres
of highly productive
spring-fed wetland currently occupied by resident
cutthroat trout only. Project partners include the private
landowner, USFWS and WDFW Landowner Incentive Program.
USGS Nutrient Assessment Study Phase III
The final phase (III) of LCFEG's three-year Nutrient
Assessment Study is occurring this summer in conjunction
with it's primary partner, the U.S. Geological Survey (USGS)
Columbia River Research Laboratory in Cook, WA. LCFEG
hopes to demonstrate the effectiveness of stream nutrient
enhancement to restore juvenile salmonid production in
watersheds previously identified as nutrient deficient.
This summer's activities follow Phases I (low-level water
chemistry assessment of the Washougal, Lewis, and Wind
River watersheds conducted in 2003) & II
(documentation of in-stream biological productivity via
assessments of periphyton (algae), macroinvertebrate
(bug), and fish production (e.g., species composition,
biomass, and growth) last year). Phase III involves the
continued collection of baseline data as well as placing
nutrient media (e.g. inorganic fertilizers or carcass
analogs) in some of these same sites. Addition of the
analogs, processed from Chinook salmon carcasses and
directly consumable
by both aquatic and terrestrial species, to
nutrient-deprived streams is expected to increase juvenile
salmon rearing densities in local streams.
