Every summer, anglers in Knox County have the chance to reel in some of Ohio’s most sought-after catfish.
Whether you're a weekend angler or a tournament competitor, the region offers some of the best summer catfishing in the state—thanks to healthy fish populations, diverse water bodies and strong support from the Ohio Department of Natural Resources (ODNR).
Top fishing spots include Knox Lake, Alum Creek and the Kokosing River.
Knox Lake, managed by the Ohio Department of Natural Resources (ODNR), is especially known for its population of flathead and channel catfish.
The lake's underwater structure—submerged logs, brush piles, and drop-offs—creates ideal habitat for these species. Anglers often report success fishing from both boats and the shoreline, particularly during the evening and nighttime hours when catfish are more active.
Knox Lake is stocked regularly with channel catfish by the ODNR, and fishing here is subject to statewide regulations, including daily bag limits and size requirements.
In addition to catfish, the lake supports other species such as largemouth bass, crappie, bluegill and yellow perch, making it a versatile fishing destination.
Alum Creek recently received over 33,000 fingerlings as part of Ohio’s stocking program. The ODNR’s long-term stocking efforts, supported by their own broodstock, ensure strong catfishing across central Ohio.
Anglers can access Alum Creek via multiple boat ramps and docks maintained by the Ohio Department of Natural Resources (ODNR). The lake allows outboard motors of unlimited horsepower, although some areas are designated no-wake zones, which can affect fishing conditions.
The Kokosing River offers additional opportunities for catfish enthusiasts. The river is home to channel catfish, bullhead catfish and possibly other species noted by the Knox County Park District.
Access points such as Riverside Park and Memorial Park provide anglers with easy entry to promising river stretches. Channel catfish in particular are active during the summer and respond well to scented baits like cut shad, chicken liver, shrimp or nightcrawlers. Flatheads, typically found in deep pools with cover, are more challenging but reward patient anglers.
While Knox County holds its own, fishing areas within driving distance like Hoover Reservoir further bolsters the region’s reputation for catfishing. Hoover is known for trophy-sized blue catfish, some exceeding 40 pounds.
