Cooper was stocked with 3,500 rainbow trout in the first week of March and will be getting another dose soon. Fishing should be good for trout and bass with warmer temperatures.

Beginning in 2016, Cooper has been stocked with coho and Chinook salmon juveniles (20,000 coho in 2019). These are often mistaken for kokanee. Anglers may retain up to 5 salmon juveniles in the reservoir as part of their daily trout bag limit. Please remember to release salmon and trout less than 8 inches.
