Mission
To protect the environmental, recreational and commercial integrity of the Hudson River and its tributaries, and safeguard the drinking water of nine million New York City and Hudson Valley residents.
Vision
The Hudson River and the NYC Watershed are healthy ecosystems teeming with life. Residents and visitors care for and help protect these ecosystems, which provide safe drinking water and abundant opportunities for swimming, fishing, boating and other recreational activities.
They began as the Hudson River Fisherman’s Association and, nearly 50 years later, they are New York’s clean water advocate, having helped set worldwide standards for waterway and watershed protection and serving as the model for more than 280 Keeper programs around the globe.
