Cooper was stocked a few weeks ago, meaning there should be lots of trout available for anglers including some holdover trout from last year. Anglers seem to be doing well on trout and bass. Bass should be picking back up with warmer temperatures in the forecast. 

Beginning in 2016, Cooper has been stocked with coho and Chinook salmon juveniles. Just recently ODFW stocked over 28,000 coho juveniles in the reservoir in 2021. 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.
