[1][4] The Hudson's Bay Company (HBC) operated a trading post (also known as Lower Post) on the river from 1888 to 1892, when the HBC sold off all its interests in the Cassiar District.

It reacquired the post in summer 1897, but shut it down again two years later due to poor returns and the re-establishment of Fort Nelson.

A notable tributary is the Cassiar River, which flows north to joins the Turnagain southeast of Cry Lake[5] and which was the focus of the Cassiar Gold Rush of the 1870s.

Part of the river flows through the Muskwa-Kechika Management Area.
