Lake Shannon is a reservoir located in Concrete, Washington, and was created in 1921 by the construction of a hydroelectric dam on the Baker River. The lake was named after James Shannon, one of the influential founders of the Seattle City Light company. Lake Shannon is fed by the Baker River and has a surface area of 179 acres. The lake's water level is controlled by the Baker River Hydroelectric Project, which also provides power to the region. The snowpack in the surrounding mountains, including the North Cascades, provides water to the Baker River, which eventually flows into Lake Shannon. The lake is used for recreational activities such as fishing, boating, and swimming. The area surrounding Lake Shannon also has several agricultural uses, including dairy farming and hay production.
