2012 Reports On Status of Milfoil Removal

585 Water Quality – FY 2012-2013: Annual Report

David Arzt, Chairman: Ad-Hoc Milfoil committee

The water quality in Crystal Lake continues to be very good. The annual maintenance was performed in the main body of the lake. Milfoil, Large Leaf Pondweed and Red Leaf Pondweed was removed. The majority of the plants were removed from the Dam Area, the entrance to Northeast Cove, the entrance to Aborn Cove and in a deep water area off of Aborn Cove.

An Aquatic Plant Survey was conducted by Northeast Aquatic Research in the fall to verify the contractor’s plant removal work and to make recommendations for work to be performed in FY 2013-2014. No milfoil was found in the main channel of the Dam Area or in shallow water portions (5’ or less) of the main body of the lake. Several milfoil plants were found off of the Town Beach in water between 5’ and 8’ deep. Large Leaf Pondweed was only found in the two coves. Red Leaf Pondweed was present off-shore and to the east and west of the mouth of the Northeast Cove as well as in both coves.

Northeast Aquatic Research conducted a second plant survey in June (at no cost to the Town) to verify and map the locations of the plants to be removed. Their recommendations for FY 2013-2014 are: Conduct the annual maintenance in the main body of the lake and the Dam Area; Monitor and remove plants in the “hot spots” off of the Northeast Cove and Aborn Cove; Remove milfoil along the shores at the Dam Area; Concentrate on the removal of milfoil in Aborn Cove; Consider removal of milfoil in the Route 140 Pond (near the Town Beach); and Conduct an aquatic plant survey in the fall of 2013.
