Flooding of the Kalahari Desert

Every year from June through August the Kalahari Desert in Botswana, South Africa is flooded with water. Prior to June, the rain in the Angola highlands causes the Okavango River to flood. Since this river has no outlet to the sea, the overflow rushes down to the desert land and stalls, saturating more than 4,000 square miles (10,359 square kilometers) of the desert floor. Then the rains stop, and the desert sun dries up the flooded desert again. During those three months, that area of the desert becomes a lush green, and animals come from miles around to drink and eat and breed. For more information click here and click here.
