context_page_description: Lake Shannon is a long, narrow reservoir on the Baker River in Skagit County, Washington in the United States. Formed in the 1920s by the construction of an arch dam just above the town of Concrete, the lake is approximately 7.5 miles long and averages 0.6 miles wide when full. Located just outside the western boundary of North Cascades National Park, Lake Shannon serves as the lower reservoir for Puget Sound Energy's Baker River Hydroelectric Project.
  Before the creation of Lake Shannon, the area was used primarily for fur trapping, logging, and concrete making. The construction of Lower Baker Dam blocked salmon migration in the Baker River. An artificial fish passage system was begun in the 1950s and completed in 1959 after the construction of Upper Baker Dam, located upstream of Lake Shannon. The lake has abundant landlocked kokanee salmon, the by-product of salmon spawning in lake tributaries. Fishing, boating and water skiing are popular recreational activities on the lake.
