Fishing at Prosser Creek Reservoir has been great, especially near the dam where the bass are biting. Anglers targeting bass should consider using worms or their preferred lures during the early morning and evening hours for the best results. However, for shore anglers looking to catch trout, it's a bit more challenging because the trout are currently positioned at a significant depth. Most of the trout at Prosser can be found around the 60-foot mark, making it necessary to have a boat to have any chance of catching them. Currently, Prosser Creek Reservoir is at 90% capacity.
