At one time the western Kalahari Region was a large, shallow inland lake, draining into the Limpopo through the Serorome Valley.

Later geological upheavals re-oriented the rivers in the region to mainly flow northeast into the Zambezi.

[2] Today the river flows through relatively flat, semi-arid country with savannah grasslands, shrubs and trees.

The river flows occasionally in the rainy season, which lasts from November to April, and for the remainder of the year it is dry.
