History & Culture
The mighty Columbia River has drawn people to its waters for over 9,000 years. Plateau peoples thrived on its rich fisheries. Trappers and traders plied its currents and rapids. The last frontier post stood watch on its shores. Grand Coulee Dam transformed the river into Lake Roosevelt. Its salmon lost, the new reservoir helped power the Northwest. Today, its scenery and stories wait for you.

Lake Roosevelt's sturgeon are 8 to 20 feet long. They are also at least 70 years old. In 1941, Grand Coulee Dam flooded the fast-moving waters they need to spawn. To help out the population, the state of Washington introduced new fish to the lake in 2006.
