Protecting clean water in our rivers, our streams and our homes is the mission of Raritan Headwaters.
Since 1959, RHA has served as the watchdog for the 470-square-mile North and South Branch Raritan
watershed, a region covering 38 municipalities in New Jersey’s Hunterdon, Somerset and Morris counties.
Throughout this beautiful region, countless pristine tributaries merge and flow into the North and South
Branches of the Raritan River. Safeguarding these “headwaters” means clean, safe water for 300,000
watershed residents and 1.5 million New Jerseyans living downstream in more urban areas that depend on the
water that comes from our rivers and reservoirs.
Raritan Headwaters is a member-supported 501(c)(3) nonprofit organization that operates under the
guidance of a Board of Trustees. We have 20 staff members, joined by an AmeriCorps watershed
ambassador, nature educators, interns and a large and enthusiastic corps of volunteers.
