Those hoping to take a dip at Gene Coulon and Madrona Beach will have to wait at least another week, as the waters of both are temporarily closed.
Washington State Department of Ecology (WSDOE) officials closed the beaches on Thursday due to high bacteria concentrations.
They recommend that people and pets “do not swim or wade at this beach, drink lake water, or engage in other water-contact activities.”
