Located at North America's geographical centre, the Red River is a large meandered waterway whose valley spreads over 880 kilometres. This river's rate of flow is extremely variable. In some areas, the rates of flow go from one extreme to another, passing from 0,03 cubic meters per second to 3 750 cubic meters per second during important rises in river levels. However, the flow of the river being generally slow, the riverbed is very shallow.
