Lower Granite Lake is a reservoir created by Lower Granite Dam. The dam is a concrete gravity run-of-the-river dam in the northwest United States. On the lower Snake River in southeastern Washington, it bridges Whitman and Garfield counties.^[1] Opened in 1975,^{[2] [3]} the dam is located south of Colfax and north of Pomeroy.

Lower Granite Dam is part of the Columbia River Basin system of dams, built and operated by the United States Army Corps of Engineers; power generated is distributed by the Bonneville Power Administration.

Behind the dam, Lower Granite Lake extends east to Lewiston, Idaho and Clarkston, Washington, and allowed the Lewiston–Clarkston metropolitan area to become a port.^[4] The first barge to Portland on the 374miles navigation route was loaded with wheat and departed Lewiston on August 9, 1975.^{[5] [6]} '
