Diablo Lake is a reservoir in the North Cascade mountains of northern Washington state, United States. Created by Diablo Dam, the lake is located between Ross Lake and Gorge Lake on the Skagit River at an elevation of 1,201 feet (366 m) above sea level.[1] Diablo Lake is part of the Skagit River Hydroelectric Project and managed by Seattle City Light.
History
[edit]The Skagit Valley was formed via runoff from Cordilleran Glacier.[3] The turquoise hue of the lake's water is attributed to surrounding glaciers grinding rocks into glacial flour that stays suspended in the lake.[4]
Diablo Dam
[edit]The Diablo Dam is a part of the Skagit River Hydroelectric Project, which is owned and operated by Seattle City Light. Construction finished in 1930 and the dam became operational in 1936.[5]
