At a maximum capacity, the reservoir covers 800 surface acres and has a maximum depth of 30 feet. Wilson Sink Reservoir receives a fair amount of angling pressure, has a put-grow-and-take rainbow trout fishery, and a self-sustaining largemouth bass fishery. Trout usually range from 13 to 17 inches and the best time to catch them is from May through September. Fly-fishing is good from a float-tube or boat, but still-fishing using nightcrawlers, corn, Power Bait, small spinner, or spoons works just as well. Trolling lures, flies, and flashers with bait also will catch fish. Bass fishing is usually fair to good during late spring and summer and the average size is about 12 inches. Shore can be productive, but in summer, fishing from a boat brings the best success. Spinner baits, crankbaits, and a variety of rubber grubs and worms are productive. BLM offers a campground, boat launch, water, restrooms, and a trailer dump.
