About this swimming hole

Marion County Park and Lake is a spring-fed 150-acre county lake southeast of Marion, separate from the larger Marion Reservoir nearby. Its one large sandy beach, on the northwest shore near the lake office, is the only place swimming is permitted in the lake. The buoyed swimming area is about 550 feet wide and extends about 150 feet into the lake's notably clear water.
