The Presumpscot River is the primary source of freshwater to Casco Bay. In total, the Presumpscot River drains 647 square miles, including the Sebago Lake watershed (442 square miles) and the lower Presumpscot watershed (205 square miles). From Sebago Lake to the Presumpscot Estuary, the river flows over 25 miles, dropping nearly 270 feet in elevation consistent with its Abenaki name, which translates to ‘river of many rough places.’ Prior to industrial development, the river supported abundant migratory fish runs and seasonal encampments where fish were harvested alongside the fourteen named falls located on the main stem. Today, 9 dams remain on the main stem, and river advocates are working closely with state and federal agencies and dam owners to restore migratory fish passage into spawning habitat in the Presumpscot watershed. The lower Presumpscot watershed is comprised of primarily forested and agricultural land, with development increasing in recent years, particularly along major transportation corridors. In recent years, the water and habitat quality of the river have improved with the cessation of pulp mill discharges in the 1990s and the removal of Smelt Hill Dam in 2002. Anadromous fish are returning to the river’s main stem and tributaries, including an annual spring migration of tens of thousands of alewives up to Highland Lake.
