n border. Along this reach it flows in a maze of channels in a swampy corridor 5–10 km wide (map 1: the border with Zambia is the eastern bank of this floodplain, not the river channel). As with all rivers in south-central Africa its flow varies enormously between the rainy season when it floods and may be several kilometres wide, and the dry season when it may disappear into marshes.
The Cuando continues in its marshy channel across the neck of the Caprivi Strip

. 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).

. 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

(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.
On the north side of the Chobe River are the Caprivi Swamps, on the edge of which is the ruined capital of the Kololo people who conquered Barotseland

in the 19th Century.
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.
Wildlife
The Cuando system is noted for its wildlife and for most of its length the land either side is protected as game reserves or wildlife management areas. Some of these suffered poaching during wars and conflict in Namibia and Angola, but with peace restored in those countries they have the chance of returning to their former state.The national parks through which it passes or on which it borders are:
