Nyaminyami, the river God. He has a body like a snake and a head like a fish and no one knows how big he is, for he never showed himself in full display. But he is very big! The people of Zambezi Valley in Zimbabwe were protected by Nyaminyami, their ancestral spirit (Mudzimu), who fed them from his own meat in times of hunger.
Whilst the waters of Lake Kariba were only just rising and the Tonga were being relocated they invoked Nyaminyami in a spirit of resistance. Although he was never used as a political symbol it was generally agreed that he disapproved of the white man's plans to build the dam. In 1957 when a 1000 year flood was recorded on the Zambezi, construction was halted and set back by flood damage. The locals nodded knowingly and waited for the final destruction during the next rainy season. This of course nearly happened with the 1958 flood which was only slightly less violent than the previous year. Elders today claim that it was only their intervention which placated Nyaminyami. In Kariba there are still occasional earth tremors from the load of the lake on the earth's surface. Locals claim that this is Nyaminyami who at the time of the sealing of the dam wall was philandering down stream towards Mana Pools He's now very lonely and only the destruction of the dam will reunite him with this wife.
