Blue-Green Algae poses a small risk to human health if a person comes into direct contact with it. It can also be a risk to animals such as dogs who may swim in or drink from affected water.

It is possible that any lake or waterbody not included on the map could still be affected by Blue Green Algae. You should visually assess all water you plan to enter and avoid contact with it if you have any concerns.
