It originates at south-west bay of the lake. The river has irregular meander pattern {{convert|350|m|ft|adj=on}} wide channel with average depth {{convert|6|m|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.
