OKAVANGO DELTA
 
   

One of the most sought after wilderness destinations in the world, the Okavango Delta gives entrance to the spectacle of wild Africa such as dreams are made of - the heart-stopping excitement of big game viewing, the supreme tranquillity and serenity of an untouched delta, and evocative scenes of extraordinary natural beauty.

    A journey to the Okavango Delta - deep into Africa's untouched interior - is like no other. Moving from wetland to dry land - traversing the meandering palm and papyrus fringed waterways, passing palm-fringed islands, and thick woodland, resplendent with lush vegetation, and rich in wildlife - reveals the many facets of this unique ecosystem, the largest intact inland delta in the world.

      The Okavango Delta is situated deep within the Kalahari Basin, and is often referred to as the jewel of the Kalahari.

        That the Okavango exists at all - deep within this thirst land - seems remarkable. Shaped like a fan, the Delta is fed by the Okavango River, the third largest in Southern Africa. It has been steadily developed over the millennia by millions of tonnes of sand carried down the river from Angola.

          Swollen with floodwaters from the summer rains, the Okavango River travels from the Angolan highlands, crosses into Botswana at Mohembo in the Caprivi, then later spills over the vast, fan-shaped Delta. The timing of the floods is uncanny. Just as the waters from Botswana's summer rains disappear (April, May), so the floodwaters begin their journey - 1300 kilometres of which is through Kalahari sands - revitalising a vast and remarkably diverse ecosystem of plant and animal life.

            The water's flow, distribution and drainage patterns are continually changing, principally due to tectonic activity underground. As an extension of Africa's Great Rift Valley, the Okavango is set within a geographi-cally unstable area of faults, and regularly experiences land movements, tremors and minor quakes. By the time the water reaches Maun, at the Delta-s southern fringes, its volume is a fraction of what it was. As little as two to three percent of the water reaches the Thamalakane River in Maun, over 95 percent lost to evapo-transpiration.

              But the flow doesn't stop in Maun. It may continue east to the Boteti River, to fill Lake Xau or the Makgadikgadi Pans, or drain west to Lake River to fill Lake Ngami.
