Ohio beaches on alert as toxic algal blooms trigger widespread advisories

More than 20 Ohio beaches have health advisories for harmful algal blooms and elevated bacteria, with four Grand Lake St. Marys beaches under red-flag warnings. The Ohio Department of Health’s BeachGuard tool uses color codes (yellow for bacteria, red for toxins) and advisories remain until tests show safe levels. NOAA forecasts a moderate HAB season on Lake Erie, while the Ohio Environmental Council calls for faster nutrient-reduction to curb blooms. Beachgoers should avoid water contact where warned, monitor updates, and follow CDC guidance to prevent illness.
