Chinook Salmon Sonar Enumeration on the Big Salmon River

This project, which has been running at this site since 2005 and funded by the Restoration and Enhancement Fund since 2011, operates a sonar station on the Big Salmon River using a long range dual frequency identification sonar (DIDSON) to enumerate the Chinook salmon escapement each year, and conducts spawning ground sampling to obtain biological information on the stock. The goal of the project is to provide a long term dataset for inter-annual stock strength, run timing, ASL composition, and annual escapement estimates (for the Big Salmon and the Yukon Rivers) in addition to verifying the accuracy of the genetic proportions from Eagle.

The program works closely with the Juvenile Chinook Out-migrant Assessment Study and the Sonar Program in Eagle, Alaska.
