John Work, an agent for The Hudson's Bay Company, established Fort Colvile near the Kettle Falls fur trading site in 1825. It replaced the Spokane House and the Flathead Post as the main trading center on the Upper Columbia River. The area was named for Andrew Colvile, a Hudson's Bay Company governor. The fort continued to be used for some time as a center of mining and transportation/supply support associated with gold rushes in the 1850s, particularly the Fraser Canyon Gold Rush. After it was abandoned in 1870, some buildings stood until as late as 1910. The site was flooded by Lake Roosevelt after construction of the Grand Coulee Dam on the Columbia River.
