Fort Colvile, Hudson's Bay Company trading post in Kettle Falls, United States

Fort Colvile was a Hudson's Bay Company trading post built in 1825 at Kettle Falls on the Columbia River, a few miles west of present-day Kettle Falls, Washington. Its square enclosure held a store and warehouses on the north side and Chief Trader McDonald's house on the east; married employees lived outside the yard to the south and west. The post also ran farms that supplied other interior posts with wheat, peas, flint corn, and potatoes.

The Hudson's Bay Company built Fort Colvile in 1825 at Kettle Falls to replace Spokane House, which was deemed too far from the Columbia River; the company moved Spokane House's property there in March 1826. It operated until June 1871, and some buildings stood until they burned on July 6, 1910. The site was flooded by Grand Coulee Dam in 1940 and added to the National Register of Historic Places in 1974.

Indigenous peoples had fished the falls for generations before the trading post arrived, and the site became a place where Native and European traders met regularly. Visitors today can find objects and stories from both worlds in nearby museum collections.

The original site is now underwater, so there are no standing structures to visit on location. Nearby museums and visitor centers offer the best way to learn about the post and see related objects.

Before the lake rose, archaeologists managed to excavate a number of objects from the site, rescuing them before they were lost. Those recovered items now form a rare physical record of daily life at a 19th-century trading post.
