Stewards protecting the health of Lake Monomonac in Rindge NH
Who We Are
The MLPOA is an all-volunteer, non-profit organization dedicated to the health and preservation of Lake Monomonac in Rindge, NH. Please join us as we strive to mitigate potential pollution in our lake and surrounding watershed.
Lake Education Day a Big Success!
On Thurs June 5, we had 10 NH DES limnologists, 42 fifth grade students from Rindge Elementary, teachers, and chaperones in 9 boats out on the lake water testing and learning about NH water quality. The kids were very inquisitive—we’re hoping to build future environmentalists! Lake Education Day furthers the MLPOA mission of educating the public about lake stewardship. We have been running this program since its inception in 1969 under founder, John Sarasin. Thanks to all for helping to make it a wonderful experience for the students by sharing or captaining a boat; RABA (Rindge Acres Beach Association) for the use of their beach in launching the boats; and of course to Laureen Moran, Lake Day Ed Coordinator and Secretary of MLPOA.

Our Annual Meeting is Sat July 19, 8:30am at the Rindge Recreation Center on Wellington Road. Mark your calendars and join us for an interesting morning learning what we’ve been up to this past year.
Spotlight: NH LAKES Congress Held on June 5
MLPOA board members Don Wilson and Jeff Eisenberg attended the annual New Hampshire Lakes Congress at the Grappone Conference Center in Concord on June 5. This premier event—organized by NH LAKES and attended by 300 participants—offered education, training and networking for lake associations, natural resource stewards, business leaders, municipal officials and political leaders committed to conservation. The conference delivered essential knowledge and skills for effective advocacy and stewardship. Through collaborative sessions and innovative approaches, attendees left equipped to safeguard and sustain New Hampshire’s lakes for generations to come.
Watershed Management Plan
The MLPOA Board is excited to announce that we have been awarded a grant from the New Hampshire Department of Environmental Services (NHDES) to develop a watershed-based management plan for Lake Monomonac. The NHDES Watershed Management Program focuses on identifying sources of, and ways to eliminate, phosphorus and other pollutants throughout the watershed with the goal of protecting and maintaining water quality. The study will begin when the most qualified consultant is selected through the RFQ process currently underway as of May 2025.
