Caution: The west boat ramp at Cooper has a severe drop off that had stopped some boats from launching and some trailers had been damaged. With recent rains this may have changed. Please use caution if using the ramp. The East Ramp has been usable.

There should be lots of leftover trout still available for anglers and bass are always around but may be in the deeper parts of the reservoir. The summer crowds are gone and Cooper is nice to visit in the winter.

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.
