This is Shasta Dam in California. Mitchell Morse and Caitlin Stockwell drove down to Redding, CA to wrap up the Shasta Reservoir fish telemetry project. They worked with California Department of Fish and Wildlife partners to remove 16 submersible acoustic telemetry receivers within the reservoir, and 5 receivers installed on Shasta Dam.

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 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.

Participants of the Fish Passage Tour view the North Shore Collector separator at Cowlitz Falls Dam, WA. Fish are collected here to allow staff to count, determine species, and sample fish as they migrate downstream.

Overhead view of the Spokane River, where adult Chinook salmon were released during a multi-tribal ceremonial fish release. During 2022 National American Fisheries Society, many scientists and citizens took part in a ceremonial fish release. Adult Chinook salmon are currently blocked by dams and unable travel upstream to their historic range.

USGS scientist Dalton Lebeda is measuring a Fall Chinook salmon captured in the Snake River. This study is being conducted to determine the percentages of natural and hatchery origin spawners in the upper reach of Hells Canyon.

Scenic picture taken with a sUAS (drone) of Hells Canyon, Fall 2023. In the bottom of the picture, you can see one of our USGS work boats pulled onto shore. USGS scientists are conducting redd surveys for spawning Fall Chinook salmon.

USGS scientist helped the U.S. Army Corps of Engineers and FISHBIO to collect and tag adult green sturgeon on the Sacramento River. The purpose of the project is to monitor fish movements and behavior in relation to flood control projects in the Sacramento River.
