The Baker River is a river located in the state of Washington, stretching for about 69 miles from its headwaters in the North Cascades to its confluence with the Skagit River. The river's hydrology is heavily influenced by its three major hydroelectric dams, the Lower Baker, Middle Baker, and Upper Baker dams, which generate 1,000 megawatts of electrical power. The Baker River system was first developed in the early 1900s for hydropower generation, with the first dam completed in 1925. The dams have created several large reservoirs in the valley, including Lake Shannon, Baker Lake, and Lake Whatcom. These reservoirs are used for a variety of recreational activities, such as boating and fishing, as well as for agricultural irrigation. The Baker River continues to play a valuable role in the economy of the region.
