2011 Milfoil Update – David Arzt, Chairman, Ad-Hoc Milfoil Committee

The annual maintenance was performed in the main body of the lake to remove a small amount of milfoil and two large beds of Large Leaf Pondweed that were first discovered in 2005 (near the Town Beach and just outside of the Northeast Cove). Approximately 0.8 acre of milfoil was removed from the Dam Area and Aborn Cove. Approximately 1.4 acres remains in the coves.

In 2012 we intend to continue the maintenance work and removal of milfoil in the Dam area, Aborn Cove and Northeast Cove.

The 2011 Aquatic Plant Mapping Report was completed by Northeast Aquatic Research. The open water areas of the lake are in good condition but the remaining milfoil in the coves will be difficult and time consuming to remove. Continued milfoil removal and monitoring of plants in the lake is recommended. See the CLA web site for additional information.
