Spotlight: 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.Â
