For successful fishing at Prosser Creek Reservoir, focus on the active shore bite near the dam on the east hillside. Fish are actively cruising the shallow waters looking for food. Shore access for anglers may be limited due to the reservoir being at full capacity though. At Prosser, it is recommended to use tubes or rapalas for bass, and consider power bait and worms for trout. Prosser Creek reservoir is currently at 100% capacity.
