River Flows

RIVER FLOWS
The hydrometric network used for the control and day to day operations of the Kariba reservoir comprise of thirteen stations where water levels are monitored daily.  Flow measurements are carried out at eight of these stations which include the Victoria Falls, one of the key stations on the Zambezi River.

Coincidentally, the maximum flow recorded at Victoria Falls was during the early construction phase of Kariba Dam in March 1958 at 10,000 cubic metres per second.  The lowest flows recorded to date at Victoria Falls were during the 1995/96 season which had an annual mean flow of 390 cubic metres per second, whereas the Long Term Mean Annual flow at Victoria Falls is 1,100 cubic metres per second.
