Blue Green Algae Update

With the hot and calm weather, we are seeing a reduction in water clarity and an overall increase in algae in multiple areas in the lake. Yesterday, we had numerous reports of blue green algae concentrations along the shoreline on both the east and west sides of the lake. We also observed some surface streaking in the open water. Our secchi disk readings dropped from approximately 7 meters to approximately 4 meters in less than 1 week, indicating that more algae is in the water column and that we may continue to see blooms in the lake.

Please continue to use extreme caution before entering the lake. Look for visual indicators of blue green algae. If you see anything suspicious, avoid it. Remember that dogs are also susceptible to blue green algae and should not enter the water in suspicious bloom areas.

If you see any suspicious blue green algae, please email photos and the location to:
