Watercourse in Manitoba and Saskatchewan, Canada, and North Dakota (USA)

At the mouth it carries 60 m³/s on average: an Olympic pool every 41 seconds. It drops from 598 m to 339 m, 0.2 m per kilometre on average. Its basin covers 46,000 km², about the size of EE. 164,000 people live in it. Highest water: June; lowest: from December to March. It is heavily dammed: reservoirs can hold 66% of a year's flow.

Water (estimated flow)Air (average) Rain (mm)Best months

From about 48 m³/s in the lowest month to 73 m³/s in the highest. An estimate: the monthly flow is modelled from the lowest and highest months of WaterGAP (RiverATLAS, 1971–2000) and the rain and snow along the river (WorldClim). Dams change the real rhythm. The chip is the average air temperature; below it, the month's rain.
