The Okavango Delta is a unique pulsing wetland. The delta covers approximately 15 000 square kilometres of Kalahari Desert in northern Botswana and owes its existence to the Okavango (Kavango) River which flows from the Angolan highlands, across Namibia’s Caprivi Strip and into the harsh Kalahari Desert.
Each year the Okavango River discharges approximately 11 cubic kilometres of water into the Okavango Delta. Most of this water is lost to transpiration by plants (60%) and by evaporation (36%) with only 2% percolating into the aquifer system with the remainder finally flowing into Lake Ngami.
The Okavango Delta is affected by seasonal flooding with flood water from Angola reaching the Delta between March and June, peaking in July. This peak coincides with Botswana’s dry season resulting in great migrations of plains game from the dry hinterland.
Generally flat, with a height variation of less than two meters across its area, dry land in the Okavango Delta is predominantly comprised of numerous small islands, formed when vegetation takes root on termite mounds, however larger islands exist with Chief’s Island, the largest, having been formed on a tectonic fault line.
The 1000th site to be inscribed on UNESCO’s World Heritage List in 2014, the Okavango Delta is an important wildlife area protected by both the Moremi Game Reserve, on its eastern edge, and the numerous wildlife concessions within Ngamiland.
Home to hundreds of species of birds and animals, you are most likely to see rarities like the Wattled Crane, Slaty Egrets and Wild dog.
