As the water sweeps into the Okavango a vast area of the Kalahari is transformed into a fertile paradise. Nowhere on our planet is the life giving power of water so clearly demonstrated. The Okavango becomes criss-crossed with trails as animals move into its heart. The new arrivals open up paths like arteries along which water flows, extending the reach of the flood. This is an Africa rarely seen - a lush water world. Some creatures are completely at home here. These are lechwe - antelope with hooves that splay widely, enabling them to move its speed through the water. For others the change is far less welcome. Baboons are somewhat apprehensive bathers. The water brings a season of plenty for all animals.
