Androscoggin River

The Androscoggin River separates Brunswick and Topsham. In addition to extensive undeveloped shoreland, the river hosts numerous islands, some conserved, that create scenic backwaters away from the main channel. It is one of the largest rivers flowing into Merrymeeting Bay.

Historically, the Androscoggin River was one of the most polluted in the nation due largely to discharges from textile and paper mills, and was a key inspiration for the Clean Water Act of 1972. The River is much renewed today. It provides important habitat, including bald eagle and great blue heron nesting sites, and great recreational boating and fishing opportunities. Sturgeon are often seen leaping out of the water near the Frank Wood bridge during spawning season. The River and the bridges spanning it are iconic, treasured features of our regional landscape.
