Swimming is permitted in all areas of the park except Kendall Lake and Indigo Lake, which are closed to swimming. However, swimming is not encouraged in rivers, streams, or ponds due to highly variable water quality. Specifically, the National Park Service discourages using the Cuyahoga River at this time. After storms, combined sanitary and storm sewers overflow upstream of the park, resulting in the release of untreated sewage into the river. These discharges can pose a threat to visitors who come into contact with river water during recreational use.
