Great Bear River
Template:Geobox The 113-kilometre (70 mi) long 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 (1,150 ft) wide 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.[1] Great Bear River contained open reaches that had melted out in place over 80 percent of its length in 1972 and 1974.[2]
The settlement of Tulita is located at the mouth of the river.
