The Groton Lakes Association is a non-profit organization dedicated to the preservation and improvement of the Lakes of eastern Groton; primarily "Lost Lake," "Knop's Pond," "Baddacook Pond" and their coves.

Located in Groton, Massachusetts, the G.L.A. works closely with local, state, and federal agencies, as well as other community organizations to develop and implement programs, strategies, and ideas which will preserve the lakes for both native wildlife and recreational use, thereby enhancing the quality of life in our local watershed.
