Coulee Corridor Scenic Byway
Lake Roosevelt National Recreation Area, WA

The west end of Lake Roosevelt is the site of historic Lake Columbia and the southern tip of the last continental ice sheet during the last ice age. This ice dammed the Columbia River and caused the Ice Age Floods to spill south and carve the Grand Coulee and other features of the Coulee Corridor. Eventually the lake disappeared as the Continental Ice Sheet receded to the north and the Columbia River returned to its northerly flowing channel.

Rent a houseboat or visit one of the 28 National Park campgrounds located along the 660 miles of shoreline around Lake Roosevelt. The sites vary from fee campgrounds with major facilities, picnic areas, swim beaches and interpretive programs to primitive “boat in” campgrounds. The Colville Conferated Tribes and Spokane Tribe also have campgrounds and facilities. The views are breathtaking and the recreation and natural landscape spectacular.
