The Tapoco hydropower project lies on the Little Tennessee and Cheoah rivers in Tennessee and North Carolina. Under a comprehensive settlement agreement and license, owner Alcoa will preserve virgin tracts of forest lands and restore flows to these Smoky Mountain streams. Now the project has earned Low Impact Certification from our partners at the Low Impact Hydropower Institute.

The Low-Impact Hydropower Institute' s (LIHI) governing board voted unanimously on May 20th to certify the Worumbo hydroelectric dam, located on Maine's Androscoggin River. The facility, owned and operated by the Miller Hydro Group, became Maine's first hydroelectric project and the tenth project nationwide to receive certification as a low impact dam from LIHI, which began giving certifications in March 2001.

The Low Impact Hydropower Institute has certified the Oswego River Project , on the Oswego River, New York and Worumbo project on the Androscoggin River, Maine as low impact hydropower projects.
