From Memorial Day to Labor Day, we test water at the beaches listed below for E.coli bacteria and cyanobacteria (blue-green algae) and their toxins to protect swimmers and other recreational water users. If a water test shows concerning results, the beach will close for swimming until levels of E. coli bacteria or blue-green algae decline.
For more information on how we test, see How We Monitor Beach Water Quality.
Always take an overall look at water conditions. Conditions can change quickly, and testing results may not always reflect real-time water quality. Swimming is not advisable after a heavy rainfall because bacteria levels in the water may be high.
Often, when one beach is closed for swimming, others are open. Check before you head out the door. This webpage is updated daily with current beach water quality conditions. You can also subscribe to get email notifications or follow us on Facebook or Twitter (@publichealthmdc) for notifications.
If you are hosting an event where people will be in the water, you might consider additional testing for E.coli and blue-green algae. See our fact sheet for different options and costs. Contact us at 608-243-0357 to schedule services.
