Mission Statement

The Lake Maspenock Preservation Association (LMPA) is a non-profit organization dedicated to enhancing, preserving and protecting the quality of the lake and its watershed through the promotion of responsible, effective environmental and educational policies.

The mission of the LMPA, to preserve and protect the lake environment, can only be met with the involvement of people like you and we greatly appreciate your support.

The LMPA Board Members and its Officers are comprised of volunteers from around the lake community.  We make every effort to respond to requests, emails and communications as soon as we are able.  Thank you for your understanding and patience with the Board as we try to keep the Lake Maspenock community and the Towns of Hopkinton, Milford and Upton informed of important events and issues happening to the lake.
