The source of the Okavango Delta flood lies in the highlands of Angola, to the north of Botswana. From here the Cubango River flows south through Namibia and into Botswana, where the river changes name, becoming the Okavango. Being such a dynamic ecosystem, the flood varies from year to year, and so no-one can say precisely how big the flood will be and when the flood waters will arrive.
This year, both Angola and Botswana Botswana have had less than average rainfall this year, which means the delta is already fairly dry. The Thamalakane River, which flows through Maun is very dry, and we have heard the Zebra are already back on the Boteti River which is earlier than previous years, the reason being the lack of rain.
