We protect drinking water and preserve land to maintain the natural beauty and enhance the livability of your town.

* Preserve and protect the 36,000 acres of the Great Swamp watershed — more than just the Refuge.
* Preserve and protect the five streams — Loantaka Brook, Great Brook, Primrose Brook, Black Brook, and the headwaters of the Passaic River — which feed the Passaic River, providing drinking water to over a million people.
* Preserve and protect the ten towns surrounding the Great Swamp Watershed — Madison, Chatham Township, Harding, Mendham, Mendham Township, Bernards Township, Bernardsville, Morristown, Morris Township, Long Hill Township.
* Serve the people who live, work, and play within the watershed.

The Great Swamp Watershed Association is a member-based non-profit organization dedicated to preserving and protecting water and natural areas for you, your family and for future generations. Our programs serve all who live, work, or play in the watershed. For over 25 years the Watershed Association has been acting on behalf of our communities to ensure that your water is safe and pure and our open space is protected.

We live just 25 miles from Times Square, in one of the most densely populated metropolitan regions in the world. In the middle of this populous area, the Great Swamp watershed offers residents and visitors nearly 36,000 acres of unique and beautiful landscape at the edge of urban and suburban development. Five streams in the watershed form the Passaic River, which provides drinking water for over a million New Jersey residents.

Development pressures are intense and open space is disappearing at an alarming rate in our watershed. The Watershed Association works every day to preserve and protect the things we love about our region — clean water, natural areas, and beautiful landscapes — lest they be lost forever.

Our vision for a better world begins with healthy communities in which the water we drink is clean and pure, and natural areas — such as the Great Swamp National Wildlife Refuge, Loantaka Brook Reservation, and Jockey Hollow — provide places where we can seek renewal and a sense of peace.
