There is a direct link between the degree to which a watershed is forested and the quality of water in the lakes and streams within it. Forests act like natural filters and produce clean, clear water. The Sebago Lake watershed is more than 80% forested which is one of the reasons why lake water quality is so great. One of the most effective ways to protect long-term water quality is to protect the surrounding forests from development. PWD works with land conservation partners to help watershed landowners conserve forested land. This partnership benefits the customers of the Portland Water District and all other users of the lake.
