SINCE 1965, CHARLES RIVER WATERSHED ASSOCIATION HAS BEEN THE VOICE OF THE RIVER.Formed in 1965 by a group of concerned citizens who raised alarm about the declining health of the Charles River, Charles River Watershed Association (CRWA) is one of the oldest watershed organizations in the country. In the fifty years since our founding, CRWA has guided the transformation of our river from the “Dirty Water” of the past–––rife with industrial pollution, sewage, trash, and even cars––to the Charles River we know and love today, one of the cleanest, most celebrated urban rivers in the country. Our MissionWe protect, restore, and enhance the Charles River and its watershed through science, advocacy, and the law. We develop science-based strategies to increase resilience, protect public health, and promote environmental equity as we confront a changing climate.
