Recreational Water Safety

The Chautauqua County Health Department (CCHD) monitors permitted bathing beaches for water quality concerns including elevated indicator bacteria, specifically Escherichia coli (E. coli), and harmful algal blooms.  If CCHD identifies water quality concerns the beach will be closed until tests show the reason for the closure no longer exits.  Please note beach operators may need to close beaches for reasons other than water quality concerns, such as staffing issues or severe weather concerns.

Beach Closures Due to Water Quality Concerns

Beaches will be closed by CCHD when water sample results show indicator bacteria levels above the Environmental Protection Agency (EPA) water-quality standards. High bacteria levels in beach water suggest a possible health risk, especially if the water is ingested or a swimmer has open wounds that allow pathogens to enter the body.

When CCHD issues a beach closure for water quality concerns beach operators are required to post signs at the beach to alert the public.  The New York State Department of Health maintains a map of Great Lakes beaches with current and historical E. coli results listed.

Beach Status

The chart below is updated with new results as results are available during the beach season. Beaches are sampled weekly or bi-weekly, depending on the likely changes in water quality for a specific beach.  A satisfactory listing does not guarantee that a beach will be open for swimming since beaches may close for reasons other than poor water quality, such as staffing problems, weather, etc.

Water quality status for permitted public beaches, based on the most recent E. coli counts, is listed below.
