   Winchester Lake is a State-owned 246 acre lake located in Winchester, CT. It has little development in the surrounding forest. Boating is made difficult by the many tree stumps, many of which are just below the surface.  There is a public boat launch and a dam at the southern end.  On average the lake is 3 meters (9 feet deep) but it reaches depths of 17 feet.

   Our September, 2007 aquatic plant survey found  twenty-one aquatic plant species, none of which were invasive. The dominant plant was Utricularia purpurea, which was found throughout  the entire lake. Vallisneria Americana that occurred with almost as much frequency. Sparganium sp., Elatine minima , Myriophyllum humile, Eriocaulon aquaticum, and Potamogeton epihydrus were also common submersed species.  Nymphaea odorata, Brasenia schreberi, and Nuphar variegata were very common in the coves. Less common were the emergents Juncus sp. and Pontederia cordata. Isolated patches of Potamogeton natans, Potamogeton bicupulatus, Potamogeton pulcher, Potamogeton amplifolius, and Utricularia radiata were present. All other species listed below were found infrequently. As expected, the highest plant densities and diversity were found in the shallow coves.
