Join us for this special lecture from the  North and South Rivers Watershed Association (NSRWA)! The North River is the first designated Scenic Protected River in Massachusetts and the North and South Rivers have been designated a National Historic Landmark by the National Park Service. Learn about the World Class Ships built at the shipyards along the North River from 1678 to 1871. Hear about wonderful activities, events, environmental and educational programs held throughout the year. NSRWA is a non-profit grass roots environmental organization dedicated to the protection of the North and South Rivers, their streams and marshes since 1970.
