WATERSHED MAPS

MYSTIC RIVER WATERSHED

The Mystic River Watershed covers 76 square miles or roughly 1% of the land area of Massachusetts. It includes all the land area that drains into the Mystic River. Its headwaters begin in Reading, MA and form the Aberjona River, then flow into the Upper Mystic Lake in Winchester. From the Lower Mystic Lake, the Mystic River flows through Arlington, Somerville, Medford, Everett, Chelsea, Charlestown, and East Boston before emptying into Boston Harbor.
