We are glad to share that Aquatic Enhancement & Survey is the contractor selected to complete the invasive species control this spring and summer. The permit application was approved by the Indiana Department of Natural Resources to treat Eurasian watermilfoil and curly-leaf pondweed in Clear Lake and Round Lake. Scott and his team have been on the lakes to assess the infestation of curly-leaf, pictured below. Check back for the timeline and treatment approach.
