Prosser Reservoir remains full as water temperatures continue climbing into the mid-50s. Trout fishing has been productive, particularly near the north end of the reservoir, where anglers are finding success with PowerBait and small spoons. Bass fishing continues to be one of the highlights at Prosser, with fish actively feeding around weed edges, submerged structure, and warmer pockets of water throughout the lake. Anglers targeting bass are reporting good results using yellow Rooster Tails and similar lure styles. With healthy water levels, active fish, and a variety of species available, Prosser remains a great option for anglers looking for either trout or bass action during the early summer season.
