Baker Lake is a reservoir located at Upper Baker Dam near Concrete, WA in Washington State. It was created in 1959 as a part of the Baker River Hydroelectric Project, which generates electricity for Seattle and surrounding areas. The dam is over 300 feet tall, and the lake can hold over 80,000 acre-feet of water. The Baker River is a major tributary of the Skagit River and is fed by snowmelt from the North Cascades Mountains. The lake is also fed by several smaller tributaries and has a surface area of over 2,800 acres. The area surrounding the lake is used for recreational activities such as fishing, boating, camping, and hiking. The lake also provides water for local agriculture and irrigation. The lake's water level is closely monitored, and adjustments are made to ensure it does not exceed safe levels.
