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.
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.
Board of Directors Meeting
April 27, 2018
There was a discussion about the 2017 Water Quality Report from Aquatic Ecosystem Research. The text of the report can be found on our website www.lakewononscopomuc.com. Scroll down to Lake Management, State of the Lake 2017. The lake was assessed monthly from May through October last year.
The study found water clarity has not changed appreciably since the late 1980s and total phosphorus levels appear to be stable since the early 1970s.
However, it found an increase in alkalinity and specific conductance that could produce higher incidences and dominance of blue-green algae populations.
State of The Lake
State of the Lake 2017
Lake Wononscopomuc was assessed monthly from May through October in 2017 at two sites located in the deep basins of the lake. The lake was found to be thermally stratified during each site visit. Resultingly, oxygen was depleted and not replenished in regions of the water column near the bottom, thus creating the environment for internal loading of phosphorus and other ions.
2016 Plant Community Study
Aquatic Ecosystem Research surveyed the plant community of Lake Wononscopomuc on July 9th and July 10th at the request of The Lake Wononscopomuc Association. The results of that study are summarized below. A more complete description of the study is presented in the remainder of this document.
2015 Summary Water Quality Report
Aquatic Ecosystem Research
The water quality of Lake Wononscopomuc was found to be in line with other contemporary studies. Our results indicate that the trophic status of the lake was mesotrophic as previously suggested by other authors. During the summer of 2015, water clarity averaged ~4.0m. Water clarity was lowest early in the season; it increased to a maximum in the month of July and subsequently diminished through October.
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.
