The Chilko is the Chilcotin River's main tributary. In fact at their confluence the Chilko River is quite a bit larger than the Chilcotin. It is also the main reason why the lower reaches of the Chilcotin are very silty. The Chilko gets most of its silt from the Taseko River, which joins it a few kilometers above the Chilko's mouth.

Name origin

The name derives from the Chilcotin language name Tŝilhqóx,[4] meaning "ochre river".[5] The related name of the Chilcotin River is from that of the Tsilhqot'in people, meaning "people of the ochre river".[6]
