During the seasons of rain and melting snow the river is very full, and liable to freshets.

The Red river is at intervals subject to freshets.
The melting of the mountain snow-caps in the spring causes severe freshets, which in turn are followed by long seasons of drought at a time when water is most needed for agricultural purposes.
