Prosser Creek Reservoir is providing a fun variety of trout and bass. At 70% full with surface temps in the low 60s, both species remain active. Bass are holding in coves and taking plastics, jigs, and crankbaits. Trout are 20–40 feet down, with trollers doing well on Rapalas and plugs. Shore fishing along the dam is producing early and late with worms, eggs, or PowerBait. While it may not produce the biggest fish, Prosser offers steady action and good variety.
