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.

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.
