Fishing Report

Very little change here as continue to report good fishing for chunky 13-to-16-inch trout and smaller bass as the surface water temperatures climb higher into the 60’s.  Fly fishermen seem to be having the best luck using leech, wooly buggers and chironomids.  Damselfly nymphs are working as well.  Mayflies are starting to hatch so pale morning duns (PMD’s), Adams and other Mayfly dries and emergers should start working.  Bass are active and showing up in the creel though mostly smaller fish are being reported. Anglers should use the same presentations, colors and techniques that are being used at South Fork Reservoir – dark soft plastic grubs and crankbaits.  Poppers can be effective during low light still water conditions.  Wilson was planted with approximately 12,000 trout this spring. The boat ramp is still not useable due to water levels and probably won’t be useable at all this summer.

Pertinent Information

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.
