West Fork has partnered with a client to implement a multi-year study to investigate the status and relative abundance of fall and spring Chinook in the Chehalis River basin. Small inclined plane screen traps designed in-house by West Fork were deployed at six sites downstream of known Chinook spawning areas.
West Fork has partnered with a client on a multiyear project to capture and tag juvenile summer steelhead rearing in the South Fork Tolt River to document reach-specific growth and movement patterns. Sampling was initiated in 2010 when PIT (passive integrated transponder) tags were first implanted in captured fish. Data has provided insight about timing of movement and growth of juvenile steelhead.
West Fork has partnered with a client to carry out a multi-year sampling effort to produce reliable smolt outmigration estimates for Coho salmon in two Olympic Peninsula rivers using rotary screw traps.
West Fork has partnered with Seattle City Light to design and implement a salmonid sampling strategy to investigate movement in selected tributaries of the Pend Oreille River in northeastern Washington.
In the Summer of 2018, eDNA collection and analysis was utilized as part of a larger project investigating fish distribution in Walsh Lake, located in the Cedar River Municipal Watershed.
West Fork Environmental conducted a three year study investigating the spatial and temporal distribution of hatchery and naturally produced sockeye salmon spawning in the Cedar River, Washington.
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 worked with Seattle Public Utilities and advisory groups to the Cedar River Hatchery to draft a Monitoring and Evaluation Plan for the Cedar River Hatchery.
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.
