The Alum Treatment has Begun!
Tuesday September 13th the alum treatment application began. The small barge went back and forth injecting alum into the water over the deepest parts of the lake. During this application period, the alum will sink to the bottom of the lake and collect algae and phosphorus as it sinks. Once on the lake bottom, it will act as a barrier to prevent more phosphorus from entering the lake from the sediments. The alum treatment will do wonders for the health of Blue Lake!
The application will take place Tuesday September 13th through Thursday September 15th. The boat launches on Blue Lake will be closed during that time to ensue the application can work efficiently and effectively. However, pedestrians may stop by to see the application taking place.
