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.
