[edit] Course

The Elk River originates from the Elk Lakes near the Continental Divide in the Rocky Mountains.[5] It flows through the Elk Valley in a southwesterly direction, joining the Kootenay River, in Lake Koocanusa, just north of the British Columbia-Montana border.

The Elk River runs through the communities of Elkford, Sparwood, Hosmer, Fernie, and Elko.

[edit] History

David Thompson traveled along the Elk River in 1811, which he called the Stag River. The river was labeled Elk River on Palliser's 1857-8 map, and "Stag or Elk River" on Arrowsmith's 1862 map.[2]

[edit] River modifications

Elko Dam was built on the Elk River in 1924. It is located approximately 16 kilometres (9.9 mi) upriver from the Elk's confluence with Lake Koocanusa.[5]

[edit] Fishing

The fishing in the Elk River was once known to be some of the best fly-fishing in North America, with greedy, large, wild cutthroat trout aplenty, but the mining, logging, and over-crowding has led to smaller and more wary fish in recent years.[citation needed]
