The Kootenay (Kootenai in the U.S. and historically called the Flatbow) is a major river in southeastern British Columbia, Canada and northern parts of the U.S. states of Montana and Idaho. It is one of the uppermost major tributaries of the Columbia River, which is the largest North American river that empties into the Pacific Ocean. The Kootenay River runs 781 kilometres (485 mi) from its headwaters in the Kootenay Ranges of the Canadian Rockies, flowing from British Columbia's East Kootenay region into northwestern Montana, thence into northernmost Idaho Panhandle and returning to British Columbia in the West Kootenay region, where it joins the Columbia at Castlegar.
Born in glaciers and flowing through a rugged landscape of mountains and valleys, the river drains an isolated and sparsely populated region of the Pacific Northwest. From its highest headwaters to its confluence with the Columbia River, the Kootenay falls more than two kilometers in elevation. Although comparable in length, watershed and discharge to the Columbia above the confluence, the Kootenay is of a notably different character; its much steeper gradient results in the formation of many rapids.
People of the Ktunaxa (Kootenai) tribe were the first to live along its banks, and for hundreds of years, they hunted and fished on the river, quite isolated from neighboring indigenous groups . In the 19th century, a Canadian explorer, David Thompson, became the first recorded European to reach the Kootenay and established trading posts throughout the region. A gold rush on the Kootenay and later silver and galena strikes in its western basins in the late 19th century drew thousands of miners and settlers to the region, who soon were followed by the arrival of railroads and steamboats. The Doukhobors, a Russian religious sect, immigrated and established a short-lived colony, Brilliant, at the Kootenay's mouth; subsequently dispersing into many settlements, they contributed to the region's lumber and agricultural industries.
