Lake Shannon

Lake Shannon (Skagit/Whatcom Counties) is a large reservoir located north of the Concrete, WA. Most of the water in the lake comes from Baker Lake, discharged by the Upper Baker Dam, but Lake Shannon also receives runoff from its 82 square mile watershed. Mount Baker and Mount Shuksan, as well as other peaks of the North Cascades, provide a beautiful backdrop to the lake.
