The 113-kilometre-long (70 mi) Great Bear River, which drains the Great Bear Lake westward through marshes into the Mackenzie River, forms an important transportation link during its four ice-free months. It originates at south-west bay of the lake. The river has irregular meander pattern 350-metre-wide (1,150 ft) channel with average depth 6 metres (20 ft). Historic air photos show no evidence of bank erosion or channel migration in a 50-year period.

The low discharge rate is due to small amount of precipitation in watershed area.[4] Great Bear River contained open reaches that had melted out in place over 80 percent of its length in 1972 and 1974.[1]

The settlement of Tulita is located at the mouth of the river.
