In the records of 1740 kept by Joseph Isbister of the Eastmain Post, there is reference to a river called Wapameg-Us-Sosh (meaning White Whale River), where a multitude of beluga is found.
It mentions that the river is located a short distance south of the Gulph  [sic] (that is Richmond Gulf or Lac Guillaume-Delisle in French).

The English name of the river was first recorded in 1744 in the logbooks of Hudson's Bay Company employees Thomas Mitchell and John Longland, while exploring the bay's coast.
On July 29, Mitchell made mention of Little White Whale River.
For the 1750 mining attempt see Richmond Gulf.

From 1853 to 1890, the Hudson's Bay Company operated a trading post, named after the river, at its mouth.
This place, now known as Jiaviniup Narsanga, has long been abandoned.
