Diablo Lake, Reservoir in North Cascades, Washington, US.
Diablo Lake contains turquoise water at 366 meters elevation, surrounded by mountain peaks and dense forests of the North Cascades range.
The construction of Diablo Dam in 1930 created this reservoir as part of the Skagit River Hydroelectric Project to generate power for Seattle.
The Skagit Valley, where Diablo Lake sits, holds significance for Indigenous peoples who maintained connections with this land through generations.
The Diablo Lake Trail extends 7.6 miles with an elevation gain of 1,400 feet, offering multiple viewpoints and access to a suspension bridge.
Glacial silt from surrounding mountains remains suspended in the water, creating the distinct turquoise color of the lake throughout the year.
