Predominant Fish Species
All species are currently managed under statewide regulations.
Largemouth bass and catfish are the most popular and most abundant sportfish in the reservoir. Channel catfish are present in good numbers with an occasional flathead showing up. Crappie fishing is fair with your best chance of fish coming from standing timber and under water structure.
Averhoff Reservoir is characterized by mud/gravel banks with overhanging brush, dead standing timber and no aquatic vegetation.
Bass anglers are most successful during the fall, winter, and spring months. Topwater baits such as buzzbaits work well in the early morning and late evening. Texas and Carolina rigged worms and lizards are also popular, and effective when fished around the overhanging brush. Catfish anglers can find channel catfish throughout the lake. Stinkbait and cutbait work well. Crappie anglers should try fishing deep structure in the fall and winter with small jigs fished on light line and tackle. During the spring, fish structure in 3 to 6 feet with small spinners and jigs.
