At the moment, fishing at Prosser Creek Reservoir can be hit or miss. Most of the fish are in deeper water, so the shore bite might be slow at times. There are some nice-size cutthroat averaging around 20 inches in length that are biting on jigs, crippled herring, or buzz bombs in the 40-foot water column near the dam. Additionally, this fishery was recently stocked with rainbow trout. The water levels at Prosser Creek Reservoir are currently at 85% capacity.
