Terror River flows northwest for about 9.5 miles (15 km) from Terror Lake to Terror Bay, on the north coast of Kodiak Island, about 30 miles (48 km) west-southwest of the community of Kodiak, Alaska. The lake and river are named after the bay, which was named in 1909 by W.C. Hodgkins of the U.S. Coast and Geodetic Survey.
Terror Lake is a natural lake in a glaciated valley within the Kodiak National Wildlife Refuge. A hydroelectric power project was built at the lake in 1985, and expanded in 2013. The project diverts water from the Terror River Valley into a tunnel that discharges water into the Kizhuyak River. The hydroelectric plant at Terror Lake replaced earlier diesel engine generators at the city of Kodiak that are now used only for peak electricity loads during the fishing season. The principal loads for the utility are the city, the U.S. Coast Guard base, and the airport.
The hydro station is owned and operated by the Kodiak Electric Association, an electrical cooperative owned by the customers. Kodiak Electric also operates six 1.5 MW wind turbines on Pillar Mountain and a 3-megawatt battery bank. Read more here and here. Explore more of Terror River here:
