Kootenays Regional Boundaries and Geography
Defining the boundaries of the Kootenays is a complex task, as the region's limits vary depending on whether one uses administrative, hydrological, or historical criteria. While the Kootenay Land District provides a general framework, the actual interpretation of the region often shifts between a strict definition based on river drainage and a broader regional identity.
Defining the Core Kootenays
In its strictest sense, the Kootenays are defined by the drainage basin of the lower Kootenay River. This specific area begins where the river re-enters Canada near Creston and extends to its confluence—the point where two rivers meet—with the Columbia River at Castlegar.

Expanding the Regional Scope
Most interpretations expand this core definition to include several surrounding areas. To the east, the region encompasses the upper drainage basin of the Kootenay River, stretching from its origin in the Rocky Mountains to the U.S. border at Newgate. This expansion incorporates the area between the Purcell Mountains and the Alberta border, including the Elk Valley of the southern Canadian Rockies (centered on Fernie) and Rocky Mountain Trench cities such as Cranbrook and Kimberley. This section also includes portions of the Flathead River drainage basin.

To the southwest, the region often includes the Salmo River basin and the Columbia River drainage from the Kootenay confluence south to the U.S. border. This addition brings the communities of Rossland, Castlegar, Fruitvale, and Salmo into the Kootenay fold.

Northern Extensions and the Columbia-Kootenay Transition
Depending on the source, several northern areas that drain into the Columbia River are also included in the Kootenays:
- The Arrow Lakes area, which includes Nakusp.
- The Upper Columbia Valley, featuring the communities of Radium Hot Springs and Invermere.
- The Golden region, encompassing the Columbia drainage between Kicking Horse Pass and Rogers Pass.
- The Revelstoke region, encompassing the Columbia drainage between Rogers Pass and Eagle Pass.

When these northern territories are included, the region is sometimes referred to as the Columbia-Kootenay or Kootenay-Columbia. However, it is important to note that these broader terms often include Kinbasket Lake and the Big Bend Country. While these are part of the Kootenay Land District, they are generally not considered part of the Kootenays themselves.
The Boundary Country Ambiguity
The Boundary Country is a southern east-west corridor drained by the Granby and Kettle River basins, situated between the Okanagan and the Bonanza Pass. Its regional affiliation is frequently debated; some classify it as part of the West Kootenay, while others attach it to the Okanagan. In some descriptions, the Boundary Country even encompasses Oliver and Osoyoos in the South Okanagan.

Historically, the settlement of the Boundary Country predates the development of both the Kootenay and Okanagan regions. If the Boundary Country is included in the Kootenays, the region can be described as the entire Canadian portion of the Columbia Basin, excluding only the lands drained by the Okanagan River.
