Cosumnes River Spawning Habitat Restoration

The degradation of spawning habitat for fall-run Chinook salmon in the lower Cosumnes river was addressed in this project. Action was taken to improve spawning habitat availability by adding spawning gravel to a select site downstream of Hwy 16. Clean, spawning gravel was added to the river bed along with the adjacent banks to improve spawning conditions and to stabilize the eroding banks.  The FFC compared pre- and post-studies to confirm the success of the gravel introduction with respect to changes in fish use, spawning habitat suitability, and movement of gravel following its placement.
