Ross Lake

Ross Lake is a reservoir that stretches through the forested mountains of the North Cascades, reaching significant depths behind a concrete dam built across the Skagit River. The water body separates Washington from British Columbia and offers a long, winding shoreline surrounded by dense woods.

The dam was built between 1937 and 1949 to create this reservoir, which was originally named after a nearby tributary creek. The project developed the area's hydroelectric power generation capabilities.

The reservoir forms part of both Ross Lake National Recreation Area in Washington and Skagit Valley Provincial Park in British Columbia.

The lake is accessible only by boat, with campsites positioned along the shoreline for overnight stays. This remote setting attracts people who fish, paddle, and explore the backcountry.

The floating cabins at a lodge on the lake shift toward the center of the water as winter approaches and levels drop. This seasonal relocation follows the natural rhythm of the reservoir.
