Each year in the Okavango Delta, a wetland whose waters slide through the Kalahari Desert in Botswana, a timeless drama unfolds, encompassing the mysteries of life and death and the power of water to deliver both. National Geographic Television captures the visual tapestry of the Okavango during the annual floodwaters that increase the river's low season flow. As the waters slowly rise, young crocodiles, swept from their nests, swim to avoid the ferocious jaws of predators. Producer/Cinematogra
