How long is Kootenay Lake? Distances between towns

Kootenay Lake is about 104 km long. The tables below measure the chain of communities along it, not the lake itself: each leg is the straight line between two published community coordinates, so a drive is always longer.

Added up, that chain runs about 150 km, because it steps from town to town around the shore and crosses on the ferry between Kootenay Bay and Balfour. The straight line from Creston to Lardeau is 121 km, and the lake itself measures 104 km end to end.

The West Arm is the narrow western branch that carries Highway 3A from Nelson out to the ferry at Balfour.

Depth and the deepest point

Kootenay Lake is about 150 m deep at its deepest, and the two sources we cite do not quite agree: Wikipedia’s infobox gives 150 m and the ILEC World Lake Database gives 154 m. Neither publishes coordinates for that point, so the map above does not mark one.

Kootenay Lake depth figures and their sources
Deepest point (Wikipedia)150 m
Deepest point (ILEC)154 m
Mean depth, West Arm (Wikipedia)10 m
Mean depth, main lake (Wikipedia)45 m
Mean depth, whole lake (ILEC)94 m
Surface elevation (Wikipedia)532 m
Two independent records, both kept where they differ. Wikipedia splits the mean depth between the shallow West Arm and the main lake; ILEC publishes one figure for the whole lake.

The West Arm is the shallow end of the lake, which is why the two records split it out. The lake level itself is measured every five minutes at Queens Bay, and that gauge is the last layer on the map.

For a map to take in the car, the Kootenay Lake Chamber of Commerce publishes route maps of the lake and the wider Kootenays on its own maps page. We do not mirror the files, so what you download is whatever the Chamber is publishing today.
