Eau Claire City-County Health Department. An accredited Health Department by the Public Health Accreditation Board (PHAB) - Advancing public health performance.

The Health Department’s Environmental Health Lab samples the water at six public beaches each week throughout the summer for bacteria levels. Beaches include: Riverview Park, Big Falls, Half Moon Lake, Lake Altoona, Lake Eau Claire and Coon Fork Beach and Campground.

Beaches are closed when sampling shows that the level of harmful bacteria is excessively high. Beaches remain closed until we can recheck bacteria levels and they return to acceptable levels. Updates will be provided daily when a beach is closed. Note: If a beach is closed on a Friday, the closed status will continue throughout the weekend.

To keep up-to-date on beach closings: sign up for e-notifications, like us on facebook or follow us on twitter @echealthdept.

The map below shows the current status (open, closed, advisory) of the beaches.
