Spokane River Red Band Trout Spawning Habitat Assessment

West Fork Environmental assessed the quality and stage-related connectivity and suitability of redband trout spawning habitat within a reach of the Spokane River where normal sediment transport processes have been altered by dams and impoundments over the past century. 

Assessment of Fish Distribution and Determination of Barriers

West Fork annually conducts surveys for the presence/absence of fish for its forestry clients to verify regulatory stream typing prior to timber harvest. Over the past ten years we have conducted over 3,700 protocol stream surveys for Washington clients alone to determine physical barriers to fish movement, resulting in a large number of changes to portions of the Washington Department of Natural Resources hydro-layer. 

Williams Creek Fish Barrier Assessment

West Fork evaluated four potential barriers in the lower 1,700 feet of Williams Creek, tributary of the Cedar River (WA) for Seattle Public Utilities to determine the likelihood for passage by Chinook, steelhead, coho and resident trout. 

Long-Term Aquatic Monitoring in the Cedar River Watershed

West Fork provided technical field assistance over four seasons in support of long-term aquatic monitoring in the Cedar River Municipal Watershed. Habitat assessments were performed throughout the 90,000 acre watershed in streams of varying size. 

Native Fish Distribution and Habitat Assessment

West Fork annually conducts stream habitat surveys to determine the distribution of native fish in streams for its forestry clients. The purpose of this work is to verify regulatory stream typing prior to timber harvest or road maintenance.

Cedar River Sockeye Spawner Distribution Study

West Fork Environmental completed the first year of a three year study investigating the spatial and temporal distribution of spawning sockeye salmon in the Cedar River between Lake Washington and Landsburg Diversion Dam.
