Prosser Reservoir is fishing best by the dam and in the cove areas. Anglers fishing for rainbows should use small kastmasters or troll behind the boat. Anglers trolling for trout at Prosser should fast troll with speedy shiners at 2 miles per hour. Anglers casting off shore should try mepps spinners, small kastmasters, rapalas, or sierra spoons.
