BeacWater Quality & Conditions

Waukesha County Park System consistently monitors our beaches for E. coli bacteria and blue-green algae during the swim season.
Waukesha County is committed to giving our customers the best experience at our beaches.  

Routine water sampling for bacteria is performed by Waukesha County Staff and the results are posted below. 

A visual check is performed for blue-green algae. If blue-green algae is suspected, the beach would be closed and sampling would be conducted with the Wisconsin Department of Natural Resources and the results would be posted below. Additional information about blue-green algae.

Water quality, Swimmer's Itch, and weather may all be factors in your beach planning. Always consider that weather conditions can change quickly.
