Three Ponds Protective Association
Protecting our Ponds, preserving our future
Three Ponds Protective Association (TPPA) is a 501(c)(3) non-profit organization created and sustained by volunteers. We're passionate about our mission to ensure the health of the Three Ponds by working to improve water quality and promote sound land-use practices.
Northeast Pond, Depot Pond (also known as Milton Pond), and Townhouse Pond are contiguous bodies of water that cover over 1000 acres and form the border between Lebanon, Maine and Milton, New Hampshire. Like many of New Hampshire’s lakes, the Ponds are currently in a vulnerable position due to heavy usage, declining water quality, invasive species, cyanobacteria blooms, and climate change.
We hope you’ll join us to preserve this valuable natural resource.
Enjoying and Protecting Milton Three Ponds Year Round
The Ponds offer an abundance of recreational activities for all seasons, from boating, swimming, fishing and kayaking in the summer, to ice fishing, skating and ice races in the winter.
Loons are regular residents and eagles can often be seen cruising the Ponds for fish or perched high in the pines. Through community engagement, education, and hands-on training, TPPA volunteers work to protect the Ponds for all to enjoy.
TPPA has many volunteer opportunities, with training provided that require just a few hours of your time. Please help us preserve the health and beauty of The Ponds for generations to come!
Healthy Swimming Mapper
Use the map to find current advisories, warnings and watches for fecal bacteria or cyanobacteria during the swim season.
Boat Inspections
TPPA supports the Courtesy Boat Inspection Program at Milton Town Beach, New Bridge Marina and Jellystone Campground. This voluntary program takes only a few minutes and helps to keep the Ponds clean by stopping the unnecessary spread of additional invasive plants and animals both into and out of our Ponds. We ask for your cooperation with these inspections.
