Prosser Reservoir remains full, with water temperatures climbing into the mid-50s as summer approaches. Trout fishing has been productive near the north end of the lake, where anglers are finding success with PowerBait and small spoons. Bass fishing is also beginning to heat up as fish move into shallower water to take advantage of warming temperatures. Anglers targeting bass should focus on weed edges, structure, and warmer pockets of water, where fish are actively feeding. Soft plastics rigged wacky style or on jig heads continue to produce the most consistent results.
