Prosser Creek Reservoir is fishing well and offering a fun mix of bass and trout. The lake sits around 70 % full, with surface temps in the low 60s. Bass are holding in coves and biting plastics, jigs, and crankbaits in 10 feet of water. Trout are suspended 20–40 feet down, with trollers finding success on Rapalas and plugs. Shore anglers near the dam are also connecting with worms, eggs, and PowerBait. While not known for large fish, Prosser offers consistent action and a great mix of species.
