The Androscoggin River runs through New Hampshire and Maine, covering a length of 178 miles. It was once one of the most polluted rivers in the country due to the paper mills that lined its banks, but since the 1970s, extensive cleanup efforts have improved the water quality. The river's hydrology is influenced by several dams, including the Livermore Falls Dam, the Gulf Island Dam, and the Berlin Dam, which provide hydropower and flood control. The river also has several reservoirs, including the Umbagog Lake, the Richardson Lake, and the Aziscohos Lake. Recreational activities such as fishing, hiking, and camping are popular along the river, and the river also supports agricultural activities like irrigation and farming.

Historical River Levels

The Androscoggin River is a river in the U.S. states of Maine and New Hampshire, in northern New England. It is 178 miles (286 km) long and joins the Kennebec River at Merrymeeting Bay in Maine before its water empties into the Gulf of Maine on the Atlantic Ocean. Its drainage basin is 3,530 square miles (9,100 km2) in area. The name "Androscoggin" comes from the Eastern Abenaki term /aləssíkɑntəkw/ or /alsíkɑntəkw/, meaning "river of cliff rock shelters" (literally "thus-deep-dwelling-river"); or perhaps from Penobscot /aləsstkɑtəkʷ/, meaning "river of rock shelters". The Anglicization of the Abenaki term is likely an analogical contamination with the colonial governor Edmund Andros.
