~ Upper Baker Dam ~ WA ~ 277 mi from PDX - 103 mi Sea-Tac.
Upper Baker Dam, part of Puget Sound Energy's Baker River hydroelectric project, is approximately 100 miles north of Seattle, located on the Baker River, a tributary of the Skagit River. The dams' two reservoirs - Lake Shannon (behind Lower Baker Dam, in Skagit County) and Baker Lake (behind Upper Baker Dam, in Whatcom County) - are fed primarily by melting snow from the slopes of nearby Mount Baker and Mount Shuksan. Lower Baker Dam lies about one mile upstream from the Baker River's confluence with the Skagit River - inside the Town of Concrete. Upper Baker Dam is about nine miles upstream from Lower Baker Dam.
Upper Baker Dam, completed in 1959, is a concrete gravity dam measuring 312 feet in height and 1,200 feet in length. A public road across the dam’s top provides access to popular North Cascades hiking trails. The powerhouse at the base of the dam contains two generating units.
