Here you will find the results of the water quality sampling done by the Washtenaw County's Environmental Health Division. Staff collect water samples from lakes, bathing beaches, and rivers throughout the County from Memorial Day through September. Samples are analyzed for various water quality parameters, such as bacteria levels, to protect public health and prevent disease.
Beaches are closed if deemed unsafe to public health.
In addition to collecting samples, an environmental survey is conducted at bathing beaches which includes evaluation of possible pollution sources, safety hazards, drop-offs, currents and hazardous objects. Lakes which host activities such as water skiing and jet skis are monitored as well. The Huron River and other rivers and streams running through the County are sampled in order to determine current water quality and to recognize trends over time. This page lists any closed public beaches. There are no beach closings at this time.
