such as buffalo, lechwe, and cattle. The natural seasonal cycle has maintained plants, fish, and animals, as they have adapted to the March–April inundation in their nutrition and breeding. Many of the local residents move their settlements annually to cope with the regular cycle of flooding. The dam removes the peak of the flooding and the trough of low water in the dry season. It reduces the natural seasonal variation of the river flow. The designers intended for the dam to 'open the floodgates' for the duration of March, and allow a flow of 300 m³/s to flood the Kafue Flats in order to maintain natural cycles. However, this has not happened in practice, mainly because the reservoir has not contained sufficient water at the right times to facilitate such a flow. The demand for electric power takes priority, and this, compounded by erratic rainfall since 1990, has prevented the dam from releasing water at the originally intended flow rates. The Itezhi-Tezhi Dam has impacted the local ecology of the Kafue Flats in the following ways: Fish production has significantly declined; Wildlife, such as Lechwe, and Sitatunga, which rely on particular timing and extent of the floods in their breeding grounds, have had their breeding behaviour disrupted, leading to population decline; In the dry season the amount of grass for grazing has reduced for both wildlife and cattle, and woody species are invading grasslands on the floodplain; There is uncertainty of the timing of flooding, and this disturbs traditional human settlements. The 2003/4 rainy season saw particularly high rainfall in Zambia. The effect of the Itezhi-Tezhi Dam release during this season is shown in the above NASA photos. According to a NASA website, in June 2004 an agreement was made with the hydroelectricity company to restore water releases from the dams according to a more natural flooding regime, presumably by keeping to the original intention of a 300 m³/s flood for the whole of March.
