Throughout the summer, water samples are collected from designated public beaches in Simcoe and Muskoka. Beaches are "posted" when there’s too much bacteria in the water and there is an increased risk of infection. Weather and other environmental factors affect a beach’s water quality. We don’t recommend you swim if it has rained heavily in the last two days prior to swimming. Heavy rains can wash bacteria, chemicals and even garbage into the water which may be a risk to your health.
