Welcome to Lakeville Lake
Also known as Lake Wononscopomuc. Nestled in the foothills of the Berkshires it is Connecticut’s deepest lake and a premiere recreational asset for swimming, sailing, canoeing and fishing in the summer and skating and cross country skiing in the winter.
The Grove and Lake Wononscopomuc are located at 36 Ethan Allen Street in Lakeville, just up the street from the Black Rabbit and Mizza’s Pizza (off of Rt 41).

About the Association
The Lake Wononscopomuc Association was formed in 1988 to protect, preserve and improve this important scenic and recreational resource for the enjoyment of present and future generations. Our mission is to promote public awareness of potential threats to the ecological health of this lake and its watershed, to improve its water quality and to discourage the growth of invasive weeds that may threaten the safe enjoyment of the lake by our community.

Bill reported the association has operated the Eco-Harvester for six seasons with great success in skimming surface weeds and pulling grasses from shallow water. It does not pull milfoil up by the roots and is less effective in deeper water where the drum goes down to 3 or more feet below the surface. It would be very effective in lakes that are not very deep and have dense weed growth.
State of The Lake 2019
Aquatic Ecosystem Research conducted a detailed water quality study of our lake between May and October of 2019. The bottom line is that our lake’s water quality is quite good and is actually improving.
Previous studies show a marked decline in water clarity and an increase in total phosphorus and alkalinity between 1934 and 1990. Most of that occurred between the 1970s and 1990s. Since then and particularly since we started biennial testing in 2015 phosphorus and nitrogen levels are generally trending down, water clarity is improving (as much as 20 feet last summer) and algae and cyanobacteria levels are low. One area that requires more attention is an increase in specific conductance. That indicates we may be getting too much storm water runoff containing salts and other deicing materials.

Maintaining a Healthy Lake
What we do can make a big difference in the health and welfare of our lake. Eutrophication is the natural aging of lakes from the addition of nutrients such as phosphorus and nitrogen. They stimulate algae and aquatic plant growth. In modern times a large percentage of these nutrients enter the lake from the development of its watershed. The watershed area of Lake Wononscopomuc is the total area from which water drains into the lake. Anyone who lives within this area has an effect on the quantity of nutrients entering the lake. The key is to limit the amount of phosphorus, nitrogen and sedimentation entering the lake.
See Our Plan
Eurasian Water Milfoil is an invasive plant that has taken over parts of the lake in depths from about 3 feet to about 18 feet. The plant has been a problem in Lake Wononscopomuc since at least 1975. Each year since the Town, Hotchkiss and the association have spent up to $30,000 per year to trim the milfoil during the growing season. The plant can crowd out native plants depriving the lake of the diversity is needs to survive in a healthy state and support its normal aquatic live population.
