Fisheries Featured Projects
West Fork has partnered with Stillwater Sciences to monitor the potential fish entrainment at Robbs Peak Powerhouse to determine when and at what flow fish migration is occurring, and at what flow entrainment, if any, is occurring.
West Fork Environmental installed four PIT tag antennas in Ohop Creek, near Eatonville, WA, to collect data leading to a better understanding of the relative importance and role of the newly restored reach on movement and residence patterns of juvenile coho within the upper system.
West Fork Environmental provided field crews to Seattle Public Utilities (SPU) in support of fisheries research and monitoring in the Cedar River Municipal Watershed for six years. Our field support for spawning ground surveys covered multiple species and locations in the watershed including kokanee salmon, Chinook and coho salmon, bull trout and pygmy whitefish.
West Fork provided field support to Seattle Public Utilities to implement an acoustic telemetry study tracking adult bull trout, rainbow trout and pygmy whitefish in Chester Morse Lake, a reservoir managed to supply drinking water to the City of Seattle.
The U.S Army Corps of Engineers, Portland District, began operating a new experimental fish collector at Cougar Reservoir in May 2014 with the goal of attracting and collecting juvenile salmon as part of a research program investigating downstream passage issues at the dam.
West Fork recently completed two studies testing the ability of cutthroat trout to ascend corrugated metal culverts using an experimental test flume.
