CTs Watershed Management Program

The Connecticut DEEP created the Watershed Management Program to more effectively address water resource issues from an integrated watershed perspective. For purposes of water management, the state has been divided into five major watershed basins along natural watershed boundaries. DEEP Watershed Managers work within these five major watershed basins to assist communities in forming partnerships, drafting watershed based plans, and implementing environmental projects to restore and protect Connecticut's water quality on a watershed-wide scale.
