Named after the President during whose administration the Grand Coulee Dam was built, this 151-mile-long artificial lake was formed by the backwaters of that dam. It serves as storage for water that is used for hydroelectric power, irrigation, and recreation. A number of towns along the river banks were flooded out by the reservoir, some of which moved to higher ground and continued in existence, such as Kettle Falls.
Opportunities for boating, fishing, swimming, camping, canooeing, and other recreational sports can be enjoyed at the lake.
