Bathing Beach and Recreational Waters Monitoring

Check on Bathing Beach and Recreational Water Monitoring Reports Before You Swim


The Bathing Beach Monitoring Program is a cooperative effort of the Ohio Department of Health, the Ohio Department of Natural Resources, local health departments with public beaches within their jurisdictions and private and public organizations along the Lake Erie border and throughout Ohio. The goal of the program is to assure a safe and healthy aquatic recreational environment by protecting the bathing public from risks of contracting waterborne diseases from exposure to contaminated waters or public health exposure to toxins found in Harmful Algal Blooms (HAB).

Information on E. coli and cyanobacteria warnings/advisories and cyanotoxin results are available on the BeachGuard webpage, Ohio has a Harmful Algal Bloom Response Strategy for responding to reports of cyanobacteria blooms, thresholds for cyanotoxin exposure, and recommendations regarding recreational use of the water when toxins are present. This strategy can be found here and this video presentation describes the strategy actions and recommendations. Samples for E. coli and cyanobactera are collected at state park beaches, and boat ramps. The sample results are listed on the BeachGuard webpage. More information on HABs can be found at Information on health effects of exposure to cyanotoxins can be found at


  • Samples and analyzes water from selected bathing beaches along the Lake Erie shoreline. This information is used to monitor changes in water quality and the status of pollution abatement activities within the Lake Erie watershed.
  • Analyzes water from various bathing beaches under the control of the Ohio Department of Natural Resources throughout the state to determine water quality and to monitor changes in the various state park watersheds.
  • Provides for prompt notification whenever the water at public beaches becomes contaminated, thereby helping to better inform the bathing public and ultimately prevent the spread of disease.

The program also highly encourages the development of localized beach water monitoring efforts, predictive models for assessing recreational water quality, pre-emptive warning systems to inform the public more effectively and aquatic sanitation programs for identifying and eliminating potential pollution sources.
