Gorham, New Hampshire 03581
The Androscoggin River Dam is a hydroelectric project located in Gorham. It is one of several dams that harness the power of the Androscoggin River, which flows through Coos County and other towns in northern New Hampshire. The dam is a timber crib structure that is 417 feet long and 20 feet high, and it creates a 32-acre reservoir. The dam diverts water to a power canal that leads to a powerhouse with four turbines and a total capacity of 2.15 MW. The dam operates as a run-of-river facility, meaning that it does not alter the natural flow of the river. The dam also provides a minimum flow of 200 cubic feet per second in the bypassed reach of the river, which protects the aquatic habitat and recreation opportunities.

The Androscoggin River is a river in Maine and New Hampshire. It is 178 miles long and joins the Kennebec River at Merrymeeting Bay in Maine before its water empties into the Gulf of Maine on the Atlantic Ocean. The river originates from Umbabog Lake in Coos County, New Hampshire, and flows through scenic landscapes, historic towns, and industrial areas.
The name "Androscoggin" comes from the Eastern Abenaki term meaning "river of cliff rock shelters" (literally "thus-deep-dwelling-river"); or perhaps from Penobscot meaning "river of rock shelters".
