Our Mission: Maintaining and preserving the ecological and recreational balance of Quaddick Lake.

Scenic Quaddick Reservoir is nestled in the northeast corner of Connecticut — near the Rhode Island and Massachusetts borders — in the town of Thompson. In 1866, the town granted the right to dam what was then called King’s Pond thus flooding the area to a higher level and creating the lake that exists today. Local residents began building summer cottages and year-round homes on the lake to take advantage of its spectacular tree-lined views, swimming in the cool reservoir, boating on its nearly 2 miles of open water and some of the best fishing in New England. During the industrial revolution the reservoir was also heavily used as a source of power as well as water for processing textile materials in the plants in Killingly.

In 1951, Quaddick was designated a state park after originally being developed as a Forestry recreation area. The site of the state park was originally a fishing area of the Nipmuck Indians and then was Thompson's town farm where elderly residents of the village spent their reflective years.

The Quaddick Lake Association (referred to as the ‘Association’) is comprised of the residents who live year-round and seasonally on the 467-acre, 2.5 mile lake. The Association is dedicated to conserving for the public benefit the natural beauty, recreational character and unique resource values of the lake and its surrounding area. In cooperation with local and state authorities and other conservation organizations, the Association promotes the protection, careful use and shared enjoyment of the lake, adjoining open spaces and wildlife so it will continue to be a cherished asset to the community.
