Massachusetts Watersheds
The Commonwealth of Massachusetts is hydrologically divided in 27 major watersheds. Each watershed has unique land and water features, history of water use, and development patterns influencing its water resources. EOEEA is committed to facilitating partnerships with state and federal agencies, conservation organizations, businesses, municipal officials, and individuals to protect and restore Massachusetts' natural resources and ecosystems for each of our 27 watersheds.
