Protecting the environmental quality of Chateaugay Lake and promoting wise stewardship
Invasive species threaten the use and enjoyment of our lake and harm its environmental health
The CLF was founded in 2007 as a charitable 501 (c) (3) organization to protect the environmental quality of Chateaugay Lake and its surroundings. The immediate threat has been the rapid spread of the invasive aquatic plant, Eurasian Watermilfoil. With the help of our donors and partners, like you, to date over 180 tons of Eurasian Watermilfoil has been removed from our lake keeping vital boating lanes clear.
Our Lake
Chateaugay Lake lies in the northern foothills of the Adirondacks. It forms the headwaters of the Chateaugay River, which feeds into the St. Lawrence River. The 12-mile-long lake system extends from Upper Chateaugay Lake through the channel of the Narrows to Lower Chateaugay Lake and the Outlet. Upper Chateaugay is 2,594 acres and has a shoreline of 18 miles. Lower Chateaugay is 545 acres with 4.5 miles of shoreline. The Narrows connects the two lakes.

What is Eurasian Watermilfoil?
Milfoil is an aquatic plant that is highly invasive. It crowds out native plants and forms thick mats that create problems for recreational uses of the lake, including boating, fishing and swimming, and lowers property values. Milfoil spreads by self-fragmenting, seeds and its rhizome base. Fragments float in a waterbody until they reroot in another location. Milfoil is difficult to eradicate once established in a water body. But the Chateaugay Lake Foundation is working hard on your behalf to control milfoil in high priority areas of the lake.
How can you help?
The Chateaugay Lake Foundation needs you! Whether you’re most comfortable volunteering time to help achieve our environmental goals, contributing money to help us target milfoil, or contacting our governmental representatives to take action, we need you on our team.
