Lower Granite Dam
Lower Granite Lock and Dam is a concrete gravity run-of-the-river dam in the northwest United States. On the lower Snake River, it bridges Whitman and Garfield counties in southeastern Washington. The dam is located south of the town of Colfax, and north of Pomeroy.
Lower Granite Dam is part of the Columbia River Basin system of dams. It was built and is operated by the United States Army Corps of Engineers. Power generated is distributed by the Bonneville Power Administration.
Lower Granite Lake, which extends east to Lewiston, Idaho, is formed behind the dam, and allowed the city to become a port. Lake Bryan, formed from Little Goose Dam, runs downstream from the base of the dam.
==Construction==
Construction began in July 1965, but was halted less than two years later due to lack of funding. Work restarted in 1970, concrete was first poured in 1971, and the main structure and three generators were completed in 1975.〔 An additional three generators were finished in May 1978, bringing the generating capacity to 810 megawatts, with an overload capacity of 932 MW. The spillway has eight gates and is long. An navigation lock was also included in construction.〔
