Blue Green Algae Update

September 23, 2017

     This warm, sunny and calm weather continues to provide potential excellent growing conditions for algae.  Based on this morning's rising temperatures and slight northern breeze, we are starting to see an increase in algal activity on the lake.

     As conditions can change quickly on the lake, so we cannot say where blue green algae will be present and whether it will reach bloom conditions.  We urge you to continue to use caution when recreating in the lake.  Please use your visual indicators before entering the water or letting your pets swim.  If you see anything suspicious, avoid it!
