The Newhalem Powerhouse is a small, run-of-river hydropower facility originally constructed in the 1920's to provide power to build the Gorge Dam and Powerhouse, and the associated construction camp. The project is located entirely on federal lands on Newhalem Creek, a small tributary to the Skagit River, which enters the river downstream of City Light's Skagit River Project. When operational (typically during late fall, winter, and spring when creek flows are highest) the Powerhouse can produce 2MW of power. Today, the project is primarily used as a source of emergency power for the Skagit River Project and associated facilities.
