Site description A vast area of swamp, open lagoon and seasonally inundated flood-plain surrounding the Kafue river as it flows from west to east before reaching the Zambezi escarpment. When wet, the alluvial clays render much of the area inaccessible and extensive cracks form on drying. The swamp is dominated by Typha and there are only scattered pockets of Cyperus papyrus. The flats are bordered by termitaria and munga woodland. At its widest point, the area liable to flooding is some 70 km across. Hydroelectric dams have been constructed at either end of the flats, although Itezhi-Tezhi (at the western end) is more important for regulating the flow and Kafue Gorge (at the eastern end) generates most of the power. An initial agreement to simulate the annual inundation has not always been followed, especially when there have been fears of water shortages. However, rainfall permitting, the cycle has been ‘smoothed’; thus the simulated flood is not as high, but lasts longer than it would under natural conditions. Many fishermen live on the numerous small islands in the centre of the swamps and other communities exist around the edges, although some of these are somewhat seasonal depending on the water-level.
