Watershed founders Kathleen Anderson Peyton and David Hunter McAlpin Sr. sought input from the Garden Club of Princeton, the Conservation Foundation (which later merged with the World Wildlife Fund), and the Brandywine Valley Watershed Association before launching the organization in 1949. Their ideas helped form the core of the work we continue today.

In turn, the Watershed helped create other organizations over the years, such as the South Branch and Upper Raritan Watershed Associations, D&R Greenway Land Trust, the Northeast Organic Farming Association of New Jersey (NOFA-NJ), and the Honey Brook Organic Farm – formerly the Watershed Farm.

In 2015, a collaboration between the Watershed, New Jersey Conservation Foundation and the Pinelands Preservation Alliance formed ReThink Energy NJ, a policy, research, and communications campaign created to accelerate the transition to renewable energy. That effort led to the creation of a new non-profit organization with the same name.

Our Watershed Institute provides technical support, small grants, and mentoring to other watershed associations in New Jersey. We also coordinate the New Jersey Council of Watershed Associations, which utilizes the collective expertise of the watershed community to act with a unified voice on issues of mutual concern.
