Prosser Creek Reservoir is providing a fun mix of bass and trout. With the boat ramp closed, shore anglers are seeing the best action. The lake is around 60% full with surface temps in the high 50s. Bass are holding in coves at about 10 feet, taking plastics, jigs, and crankbaits. Trout anglers near the dam are getting bites with worms, eggs, and PowerBait. While not known for big fish, Prosser continues to offer steady action..
