The project will remove two dams, the Upper Town Dam and the Remnant Mill Dam from the Sabattus River, a tributary to the Androscoggin River in Maine. Both dams will be removed, with bank restoration, stabilization, and revegetation.  These dam removals will eliminate public safety hazards, reduce flooding risk, restore parks and safe access to nature for disadvantaged communities, and restore passage for Federally endangered Atlantic salmon, river herring, and other species to important spawning habitat in the Androscoggin watershed.

The National Fish Passage Program combines technical expertise with a track record of success. 

The National Fish Passage program works with local communities on a voluntary basis to restore rivers and conserve our nation’s aquatic resources by removing or bypassing barriers. These projects are designed to benefit both fish and people. Since 1999, the program has worked with over 2,000 local communities, Tribes, and private landowners to remove or bypass over 3,400 barriers to fish passage fish passage
Fish passage is the ability of fish or other aquatic species to move freely throughout their life to find food, reproduce, and complete their natural migration cycles. Millions of barriers to fish passage across the country are fragmenting habitat and leading to species declines. The U.S. Fish and Wildlife Service's National Fish Passage Program is working to reconnect watersheds to benefit both wildlife and people.

and reopen access to over 61,000 miles of upstream habitat for fish and other animals. 

Fish passage project proposals can be initiated by any individual, organization, government, or agency. However, proposals must be submitted and completed in cooperation with a Fish and Wildlife Conservation Office. Please note that fish passage projects being used for federal or state compensatory mitigation or required by existing federal or state regulatory programs are not eligible for funding through the National Fish Passage Program.
