The creek which flows into Tincup Lake is called Gyǘ Chù because of the king salmon which come up from the Donjek River. Used today mostly by Burwash people, formerly Southern Tutchone from Aishihik also came here. The area is mostly important for the dog salmon run. It is one of the few places in the region where the salmon come in any numbers. They were caught in cone-shaped fish traps from six to eight feet long made of small poles laced with spruce root.
