Little Tuya River

The Little Tuya River is a river in far northwestern British Columbia, Canada, flowing southeast from the Nahlin Plateau to meet its parent, the Tuya River a few kilometres upstream from the latter's confluence with the Stikine River. It is the Tuya's only significant tributary.

Coal has been found in rocks exposed in the drainage of the Little Tuya River and Mansfield Creek, which is also a tributary to the Tuya River, between the communities of Dease Lake and Telegraph Creek in northwestern BC. The coal was first discovered in 1904, but the main exploration of its economic potential occurred in the 1980s to 1990s.
