Basin size3,401 km2 (1,313 sq mi)[1]

 • average25.9 mm/a (1.02 in/year) unit runoff[2]

It rises near Fort Rixon, Insiza District, and flows into the Mzingwane River near West Nicholson.

Hydrology Edit

The upper reaches of the Insiza River are ephemeral, but below Silalabuhwa Dam, the river flows for two-thirds of the year.[2]

Major tributaries of the Insiza River include the Inkankezi and Siwaze Rivers.

Cities, towns and settlements along the river Edit

The settlements below have are ordered from the beginning of the river to its end:

Bridges and crossings Edit

 
Croft Bridge on the Insiza River near Filabusi.

There are four main bridges over the Insiza River:

There are also a number of crossing points, including:

  • Ekusileni pontoon (see photo at top of page).

Development Edit

 
Silalabuhwa Dam.

In addition to a number of small weirs, there are four dams on the Insiza River:

  • Upper Insiza Dam, near Fort Rixon, built in 1967 with a full supply capacity of 8,829 MCM (million cubic metres).
  • Insiza Dam, previously known as Mayfair Dam and Lake Cunningham, built in 1973, with a full supply capacity of 173,491 MCM. It supplies water to the city of Bulawayo.
  • Pangani Dam, near Filabusi, built to supply water for Pangani mine (now closed and site of a youth training institute.
  • Silalabuhwa Dam, built in 1966, with a full supply capacity of 23,454 MCM. It is located near the confluence with the Mzingwane River and supplies water for irrigation to the Silalatshani Irrigation Scheme [3] and to Colleen Bawn.[4]
