Lake Roosevelt National Recreation Area, Protected natural area in the United States

Lake Roosevelt National Recreation Area protects Franklin D. Roosevelt Lake, a 130-mile (210 km) reservoir on the Columbia River between Grand Coulee Dam and Northport, Washington. The lake fills the river valley behind the 1941 dam, with dry, rocky shorelines and many coves. The area also takes in Crescent Bay Lake in Grant County and historic sites at Fort Spokane and St. Paul's Mission.

Grand Coulee Dam was constructed in the early 1940s and artificially created this massive water body. The region was previously home to Native tribes and contained historic frontier sites including Fort Spokane and St. Paul's Mission from the 1800s.

The recreation area was renamed for Franklin D. Roosevelt in 1996, over objections from the Colville Tribe. It was created in 1946 by a memorandum of agreement with the Spokane Tribe, the Colville Indian Reservation and the Bureau of Reclamation, and has never been established by Congress or the president. Visitors can see Fort Spokane at the Columbia-Spokane confluence and St. Paul's Mission, a Jesuit church built near Fort Colville in the 1830s above Kettle Falls.

The recreation area has 22 public boat launches, plus 4 more on the Colville Reservation available to non-members by permit. There are 3 standard campgrounds and 9 boat-in campgrounds. The reservoir is drawn down in winter, so check current water levels before launching.

It was established in 1946 as the Coulee Dam Recreational Area and renamed for Franklin D. Roosevelt in 1996, over objections from the Colville Tribe. With Curecanti National Recreation Area, it is one of two national recreation areas never established by Congress or the president.
