At maximum capacity, Willow Creek covers 640 surface acres and has a maximum depth of 40 feet. It is known primarily for white crappie; which generally range in size between 6 and 10 inches. The best time to catch crappie is from May through July and boat fishing is best, but shore fishing along deep drop-offs is also productive. Brightly colored jigs work well as does trolling small spinners and crankbaits. The reservoir also offers the opportunity to catch largemouth bass ranging in size from 8 to 12 inches and channel catfish up to 12 lbs. Fly-fishing is less productive since the water is always cloudy. Rubber worms, jigs, and crankbaits work well for bass in the spring. Stink baits, liver, nightcrawlers, and shrimp work well for catfish during spring and summer. There is primitive camping for small RVs and tents, but bring your own water and firewood. Car-topper boats, canoes, or float tubes are recommended. It is difficult to launch trailered boats when the water level is low in summer; however, a gravel boat ramp is usable during high water.
