Valley Lake Algae Treatment

On June 17, 2025, ILM conducted an algae control visit of Valley Lake. It was observed that approximately 15% of the lake was covered with algae, with excessively large amounts of growth accumulating down wind in the north west corner of the lake as well as the southwest corner of the lake near the swimming beach. A liquid algicide application was executed using the spray boat. Eight tank mixes were applied to ensure thorough and even distribution of product to all floating filamentous algae. Both the fire hose and boom system were employed during the treatment. A granular algicide application was also executed around the perimeter of the lake. The next algicide treatment is scheduled for July 3rd, depending on lake conditions at the time.
