Fishing Report

Water quality at Wilson Reservoir remains fair with relatively clear water and only  a few patches of algae. Trout anglers continue to do well from shore and  boat early and late in the day.  Trout fishing should remain good through fall with anglers having success catching fish averaging 15-16 inches and some top end trout around 20-21 inches. Anglers should have success fishing rooster tails, spoons, Rapalas, or bait fishing an inflated worm a couple feet off the bottom. Water levels at Wilson have been declining and the boat ramp will not be useable for larger watercraft and likely completely inoperable by the end of October.

Bass fishing was good this summer with many fish being reported in the 2-3 pound size class. Bass fishing will begin to slow down with the cooler weather forecasted.

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.
