<P> From 1958 to 1961,' Operation Noah' captured and removed around 6,000 large animals and numerous small ones threatened by the lake's rising waters . </P> <P> On the 6th of February 2008, the BBC reported that heavy rain might lead to a release of water from the dam, which would force 50,000 people downstream to evacuate . Rising levels led to the opening of the floodgates in March 2010, requiring the evacuation of 130,000 people who lived in the floodplain, and causing concerns that flooding may spread to nearby areas . </P> <P> In March 2014 at a Zambezi River Authority organized conference, engineers warned that the foundations of the dam had weakened and there was a possibility of dam failure unless repairs were made . </P> <P> On 3 October 2014 the BBC reported that "The Kariba Dam is in a dangerous state . Opened in 1959, it was built on a seemingly solid bed of basalt . But, in the past 50 years, the torrents from the spillway have eroded that bedrock, carving a vast crater that has undercut the dam's foundations....engineers are now warning that without urgent repairs, the whole dam will collapse . If that happened, a tsunami - like wall of water would rip through the Zambezi valley, reaching the Mozambique border within eight hours . The torrent would overwhelm Mozambique's Cahora Bassa Dam and knock out 40% of southern Africa's hydroelectric capacity . Along with the devastation of wildlife in the valley, the Zambezi River Authority estimates that the lives of 3.5 million people are at risk ." </P>

The kariba dam is located on the okavango river between the countries of zambia and zimbabwe
