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.
