Located along the Skagit River, Diablo Dam once stood as the world’s tallest dam at 389 feet, and it was through this that Diablo Lake was formed. The devil’s in the details and the details are in the color. Fine glacier sediment feeds into the lake through creeks, giving the water its brilliant turquoise luminosity.
The Diablo Dam, named from a Chinook word influenced by early Spanish explorers meaning "devil," was once the world's tallest dam, standing 389 feet tall. Today, the uniquely colored waters of the lake are home to brown and rainbow trout. The surrounding glaciers grind rocks into a fine powder that stays suspended in the lake reflecting an intense turquoise color.
