Please be advised that Cyanobacterial (Blue-Green Algae) has been identified in the water at this location. Additional information can be found online at AHS Health Advisories

Visitors are advised to take the following precautions:

• Avoid all contact with cyanobacterial blooms. If contact occurs, wash with tap water as soon as possible.
• Do not swim or wade or allow your pets to swim or wade in any areas where cyanobacteria is visible.
• Do not feed whole fish or fish trimmings from this lake to your pets.
• Consider limiting human consumption of whole fish and fish trimmings from this lake, as it is known that fish may store toxins in their liver. People can safely consume fish fillets from this lake.

As always, visitors and residents are reminded to never drink or cook with untreated water directly from any recreational body of water at any time. Boiling this water will not remove the toxins produced by cyanobacteria. An alternative source of drinking water should also be provided for pets and livestock while this advisory is active.

Weather and wind conditions can cause algae blooms to move from one location in the lake to another. As such, this advisory will remain in effect until further notice.

Please note: Waters in which the cyanobacterial bloom is NOT visible can still be used for recreational purposes, even while this Health Advisory is in place.
