    Windy AI 08 July 2026
    Lake Diablo is a deep, turquoise-colored reservoir in the North Cascades of Whatcom County, Washington, formed by the Diablo Dam on the Skagit River within the National Park Service complex. Its stunning emerald-green water, dramatic mountain setting, and exceptional clarity make it one of the most visually spectacular fishing locations in the Pacific Northwest, supporting rainbow and cutthroat trout in its cold, clear depths. Spot Features: Lake Diablo is a reservoir on the Skagit River in Whatcom County, Washington, within North Cascades National Park, created by the Diablo Dam. Access requires a boat tour or permit from Seattle City Light, rainbow and cutthroat trout respond to small spinners, flies, and bait in this exceptionally clear and scenic lake surrounded by some of the most dramatic mountain terrain in Washington. Seasonality: Rainbow trout and cutthroat trout are the primary targets at Lake Diablo, active from spring through fall in the cold, clear North Cascades water. The lake's high-elevation setting creates a relatively short open-water season, typically May through October, with the best fishing in spring and fall.
