Trout fishing may be good on warmer days. Try fishing for bass around aquatic vegetation in the mid-morning and late afternoon hours. One thousand catchable trout were stocked in the lake in early February, with another stocking scheduled for the next week. Fishing may be picking up over all in Cooper Creek.

Beginning in 2016, Cooper has been stocked with coho and Chinook salmon juveniles. 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.
