Kootenay River, River system in British Columbia and Montana, United States.
The Kootenay River is a river system that flows for about 780 kilometers from the Canadian Rockies through Montana and Idaho before rejoining the Columbia at Castlegar in British Columbia. Along its course, the waterway is dammed at several points to generate electricity.
Fur trader David Thompson first documented this river in 1807 and established trading routes connecting Canadian and American territories. This exploration marked the beginning of European use of this river passage.
The name comes from the Ktunaxa indigenous people who lived in this river valley and built fishing settlements on its banks. You can still sense this cultural heritage in communities along the waterway today.
The river is accessible at many points for activities like fishing and wildlife watching along its banks. Best visiting times depend on your planned activity, as water conditions vary with the seasons.
The river name changes from Kootenay to Kootenai when crossing the Canada-United States border, a difference that reflects regional language traditions. This name shift shows how borders influenced historical naming practices.
