Umguza River has many tributaries that join to it before it flows
out of the city of Bulawayo, some of these tributaries like Mazayi
and Matsheumhlope pass through industrial areas and many residential
areas. The vicinity of the river and its tributaries to the urban
area exposes it to excessive pollution through sewer bursts,
industrial waste and general human pollution. There are also small
scale commercial farmers scattered along the river basin. Umguza
River is impounded by upper Umguza dam and lower Umguza dam.
