Protecting Water

Your voice for the environment

Water is our most fragile and precious resource. Essential to all forms of life and to our economies, our water supplies face a myriad of threats from pollution to climate change. Keeping our water clean, safe and healthy in the face of these challenges is the heart of the Watershed’s mission. Our strategy for doing so involves scientific investigation, advocacy at the state and local level, enhanced land and water stewardship, and education to expand environmental literacy.
