artifact description
The Presumpscot River flows 27 miles from Sebago Lake into Casco Bay and the Gulf of Maine.The river’s watershed encompasses 205 square miles of primarily forested and agricultural land. The river itself has a history of extensive industrial use since the early 1700s. By the 1950s, the river had nine dams and was so polluted that fumes from the river peeled paint off nearby homes. Prior to industrialization, there were abundant salmon, alewife, shad, smelt, and eel fisheries, which have since been greatly diminished.
