The Cuando continues in its marshy channel across the neck of the Caprivi Strip of Namibia (map, 2) and then forms the border between Namibia and Botswana as it continues south-east. Some 10,000 years ago, the Cuando merged with the Okavango River and they flowed south to Lake Makgadikgadi, but the land in that area was uplifted. As a consequence the Cuando now meets slightly higher ground (map, 4) and breaks up into many channels and swamps (called the Linyanti Swamp) dotted with alluvial islands, nearly disappearing into the Kalahari sands like the Okavango (map, 5). But instead it has diverted east and has been captured by the Zambezi. The flow turns sharply east, still forming the border with Botswana. In the dry season there are few open channels through the swamps and marshes. Beginning at this point it is known as the Linyanti (map, 6), and after it flows through a seasonal lake, Lake Liambesi (map, 7), it is called the Chobe (map, 8). The river then flows into the Zambezi just above the Kazungula Ferry (map, 9).
In years when the Okavango experiences a good flood some of the water escapes east along the normally dry channel of the Magwekwana River into the Linyanti Swamp, thus entering the Zambezi basin. Otherwise the Okavango basin has no outlet.
So much of the water of the Cuando, Linyanti and Chobe is lost to evaporation in the various swamps that its contribution to the flow of the Zambezi is very small except in occasional years when it floods excessively.
