Please note: Algal blooms are now present at Fanshawe Reservoir and users are asked to exercise caution. While blooms that occur in our reservoirs are generally considered a nuisance, there are some cases where these blooms may contain blue-green algae, which can produce toxins. Always assume that toxins are present in an algae bloom and avoid contact with the water. Keep those at higher risk, children, and pets, out of the water.
