Stony Brook-Millstone Watershed Association is central New Jersey's first environmental group!  Since 1949, we have protected clean water and healthy habitat through conservation, advocacy, science and education.  We maintain a 930-acre nature reserve with over 10 miles of hiking trails in Hopewell Township.
