In this photo a USGS Biological Science Technician Brittany Graham is surgically implanting an acoustic telemetry tag into a juvenile salmon on the banks of the lower Shasta River. The Western Fisheries Research Center (WFRC) uses fish with acoustic transmitters to track fish movements and estimate survival. This information provides water managers with ro

This is a landscape photo of the Klamath River with mountains on either side of the photo. The Western Fisheries Research Center is researching the effects of flow management before and after dam removal on juvenile Chinook salmon survival to the ocean. 

Collin Smith and Georgia Martin are inserting passive integrated transponders in juvenile Chinook Salmon at Fall Creek Hatchery, California to track their movements. Data are collected for each fish, including length, weight, and the individual number of the inserted tag.

This photo shows the California Department of Fish and Wilflife’s screw trap on the lower Shasta River, where Western Fisheries Research Center (WFRC) scientists surgically implant acoustic telemetry tags and passive integrated transponder tags into juvenil Chinook salmon collected at this site.

This is an image of a stormwater drain in Seattle. Dangerous tire particles, such as 6PPD-quinone, can land up in water bodies through drains such as the one depicted above and can cause deaths in a variety of fish, including salmon.

This is Keno Dam, in Klamath, OR. The Western Fisheries Research Center (WFRC) is doing work here to ensure proper fish passage is functioning and to provide science to help better address the water needs of the Klamath River Basin.

The Western Fisheries Research Center (WFRC) is partnering with the U.S. Bureau of Reclamation to discuss ways to monitor fish passage at Keno Dam. With the recent removal of four mainstem dams along the Klamath River, Keno Dam now stands as the most downstream fish passage challenge , and the first major obstacle for migrating salmon returning upstream.

Check out these photos from the field! Lisa K Weiland (sitting) and Leah Tai from the U.S. Fish and Wildlife Service are shown above. This project is working to learn how larval lampreys use soft substrates for burrowing.

This is a photo of pelicans on the Upper Klamath Lake in Klamath Falls, OR. The USGS Western Fisheries Research Center (WFRC) has a field station in Klamath Falls. Scientists at the WFRC monitor suckers in the Upper Klamath Lake.

This is a drone photo of the bio-acoustic fish fence in the Georgiana Slough, a tributary of the Sacramento River Delta. It is used to guide fish safely out to the ocean.

Stakeholder interests have spurred the reintroduction of the critically endangered populations of Chinook Salmon to tributaries upstream of Shasta Dam, in northern California. We released two groups of acoustically tagged, juvenile hatchery, late-fall Chinook Salmon to determine how juvenile salmon would distribute and survive.
