Jackson Lake sits within the 349-acre Jackson Lake State Park in Jefferson Township, approximately two miles west of Oak Hill. The 251-acre impoundment features an 11-mile shoreline surrounded by steep hills and woodland terrain, offering some of the most scenic country in southeastern Ohio. Created in 1938 and dedicated as a state park in 1979, the lake maintains a relatively shallow profile with a maximum depth of 12 feet, though most areas remain six feet deep or less. This shallow, warm-water fishery provides excellent opportunities for largemouth bass, channel catfish, crappie, and bluegill. The area holds historical significance, with remnants of Civil War-era iron furnaces like the Jefferson Furnace visible within the park boundaries. The lake's peaceful setting and accessible shoreline make it an ideal destination for anglers seeking a relaxing retreat with consistent fishing action.
