Fish Habitat

The GYWC coordinates a number of Fish Habitat programs including the monitoring and restoration projects highlighted below which leverage the support of a diverse network of local volunteers, landowners, partner organizations, and funders to improve watershed conditions for local fish and aquatic organisms.

Monitoring Programs

Fish Spawning Surveys

Join us for spawning surveys as we hike and wade through waters of the forested coastal foothills of the Greater Yamhill Watershed to GPS document observations of spawning native fish species and their habitat, including Coho salmon, winter-run Steelhead trout, and Pacific lamprey.

Fish Snorkel Inventory — Rapid Bioassessment (RBA)

Join us for field days as we hike the creeks and rivers of the forested coastal foothills of the Greater Yamhill Watershed in our chest waders to document observations of spawning native fish species and their habitat. Help us document live fish and carcasses, egg nests in the stream gravel (called redds), and important habitat features such as active side-channels, large woody debris complexes (LWD), and fish passage barriers.
