Coho Salmon Monitoring
Coho salmon monitoring in the Russian River basin
SGEP Advisor Paul Olin and staff operate an ongoing monitoring program for coho salmon in the Russian River basin to document in-stream survival of juvenile coho, outmigration of smolts, and returns of adult fish. Efforts are primarily focused on monitoring for the Russian River Coho Salmon Captive Broodstock Program and activities are concentrated on historic coho streams in the southern portion of the watershed in western Sonoma County.
Rearing and stocking of Broodstock Program fish is conducted by program partners at the Warms Springs Hatchery. Sea Grant biologists conduct seasonal monitoring activities, following the coho salmon life stages:
Innovative PIT tag technology allows biologists to collect data on fish numbers, movement, and distribution at all life stages. This technology has been an invaluable tool for monitoring coho in the Russian River basin.
The Broodstock Program monitoring effort is funded by the US Army Corps of Engineers. Additional studies are funded by the National Fish and Wildlife Foundation and California Department of Fish and Wildlife, with contributions from and the Sonoma County Water Agency. All of our work is made possible through the gracious support of hundreds of private landowners throughout the Russian River watershed.

Evaluating instream flow needs of juvenile coho
Dr. Olin and his staff are also conducting a study to correlate flow with survival in order to quantify the instream flow and habitat needs of juvenile coho during the summer months. See our Oversummer Flow and Survival Study page for more information.
