Water Quality Update for August 20, 2019

August 20, 2019

We are seeing very different conditions today with the hot, calm weather allowing the BGA to concentrate at the surface.  We are seeing extensive blooms in the northern half of the lake.  Clarity has dropped by almost two meters in the north basin in 48 hours and we are seeing extensive blooms along the east and west shoreline and many bloom patches and lots of streaking in the mid lake area. Further south near Onanda Park, water clarity is somewhat better  with Secchi disk readings of 5.7 meters.  However, we were still seeing significant dots in the water column in this area.  We have had some reports of surface streaking in the southern half of the lake as well. 

    

Please use caution before entering the water.  It is very important to remember to use your visual indicators while using the lake. Please stay out of the water in areas where there are bloom like conditions. It is impossible to tell whether or not a bloom is toxic by looking at it, so please avoid these areas. Please remember that pets are especially vulnerable to Blue Green Algae since they drink a lot of water when in the lake and the algae can concentrate on their fur and they can ingest large quantities when they groom themselves.
