Your water. Your environment. Your voice.


The Stony Brook-Millstone Watershed Association is central New Jersey’s first environmental group. Since 1949 we’ve worked to protect your water and environment through conservation, advocacy, science and education. We speak out for your water and environment, protect and restore sensitive habitats, test our waterways for pollution and inspire others to care for and protect the natural world. Our goal is to improve the health and quality of central New Jersey’s water and sustain a network of protected habitats for wildlife and people. With a track record of more than 60 years of effective environmental protection we are one of the most respected local environmental organizations in the country.

From scientific reports and how-to guides, to curriculum for teachers and our own informative newsletters, the Watershed Association offers a wide array of resources for residents, businesses, government leaders and other organizations.
