Franklin D. Roosevelt Lake (also called Lake Roosevelt) is the reservoir created in 1941 by the impoundment of the Columbia River by the Grand Coulee Dam in Washington state. It is named for Franklin D. Roosevelt, who was president during the construction of the dam. Covering , it stretches about from the Canada–US border to Grand Coulee Dam, with over of shoreline; by surface area it is the largest lake and reservoir in Washington. It is the home of the Lake Roosevelt National Recreation Area. The reservoir lies in parts of five counties in northeastern Washington; roughly in descending order of lake acreage they are Ferry, Stevens, Lincoln, Okanogan, and Grant counties. Etymology Originally, the Bureau of Reclamation referred to the impoundment formed behind Grand Coulee Dam as the Columbia Reservoir. It was unofficially referred to as "Columbia Lake" and "Empire Lake" by local newspapers, including the Colville Examiner in Stevens County; the latter name was chosen in a 1941 contest organized by the Spokane Daily Chronicle and forwarded to the Department of the Interior as a suggestion. "Empire Lake" was suggested by 113 entries and was among the most popular of the suggestions, which also included "Grand Coulee" (later used for a separate reservoir), "Sunset", "Spokane", and "Roosevelt"; entries with the name "Columbia" were not considered due to its previous rejection by federal officials as an official name. On April 17, 1945, five days after the death of President Roosevelt, Secretary of the Interior Harold L. Ickes renamed the reservoir Franklin D. Roosevelt Lake. Secretary Ickes stated this token honor recognized how President Roosevelt championed the dam and advocated the legislation to create it.
