The Savuti Channel has a fascinating history of flooding and drying up independently of good rainy seasons and flood levels elsewhere – a mystery that has intrigued geologists and other researchers for many years. It is generally believed that tectonic activity deep below the Kalahari’s sand bed is responsible. Others argue that its flow is primarily dependent upon the rainfall in the Angolan highlands which feeds the Okavango and Chobe River basins and the channel.
In 2008, the Savuti Channel, having been dry for many years, once more became a deep, clear waterway harbouring Hippo and other aquatic life with a large variety of waterbirds. Wildlife, from plains game to predators, has had to adapt to a new source of water and all the opportunities and menaces it has brought with it. How long will it be before the water dries up again? Judging from historical records it could be more than a hundred years or less than ten. Nature has the final say in such matters.
