This green area of wetlands in southern Sudan includes Lake No, near the river at the top, the Zefah Game Reserve, center, and part of the swamp of the Sudd, below. Several fires are visible just west of the wetlands.

Lake No is a lake in Sudan. It is located just north of the vast swamp of the Sudd, at the confluence of the Bahr al Jabal and Bahr el Ghazal rivers. It marks the transition between the Bahr al Jabal and White Nile proper.

The Sudd, also called the Bahr el Jebel, As Sudd or Al Sudd in southern Sudan, is a vast swamp formed by the White Nile. The area covered thereby is one of the world’s largest wetlands and the largest freshwater wetland in the Nile basin.

The sands of the Kalahari Desert in Botswana appear green where the Okavango River pours onto them, creating the Okavango Delta. The other green area at the top is swampland in Africa’s “Four Corners” region.

The delta is fed from Angola’s October to April rainy season, although the waters generally don’t reach Botswana until December and don’t travel to the bottom end of the delta until July. As this image was taken in early October, at the start of Angola’s rainy season, the delta has not yet expanded to its maximum area.

Lake Alakol, meaning “mottled lake” in Turkic, is a lake located at an altitude of 347 m in the Almaty and Shyghyz provinces of east central Kazakhstan, east of Lake Balqash. Here, green and tan sediments give it the mottled coloring for which it is named.

The lake is the northwest extension of the region known as the Dzhungarian Gate (Alataw Pass), a narrow valley connecting the southern uplands of Kazakhstan with arid northwest China.

The Dzhungarian Gate is a fault-bounded valley, appearing here as a vertical line along the south side of the lake, where the elevation of the valley floor is between 350-450 m above sea level while the peaks of the Dzhungarsky Alatau range (bottom) reach 4,463 m above sea level.

Lake Alakol, a salt lake, has a drainage basin of 65,200 km² and receives water periodically from the southerly draining Urdzhar River. The surface area of the lake is 2,650 km², its maximum depth 54 m, and its volume 58.6 km³.

A swampy, lowland connects the northwest end of Lake Alakol with the lighter-colored Lake Sasykkol (left of center). The Alakol State Sanctuary has been created to protect the area, for the lake is an important breeding and nesting ground for various wetland birds, notably the very rare Relict Gull.

Numerous important bodies of water and wetlands areas are visible in this fine, cloud-free image of Botswana, Angola, Zimbabwe, Zambia and the Caprivi Strip zone of Namibia.

In Botswana, which occupies the lower portion of the image, the Okavango River and Delta can be seen on the left, and the Makgadikgadi Salt Pans to the right.

Above the Okavango Delta is the Cuando River, which leads to a place known as Africa’s “Four Corners”, as Namibia, Botswana, Angola and Zambia share a quadruple frontier near the triangular swampy area visible northeast of the delta.

The upper portion of the image contains the Zambezi River and Barotse Floodplain in Zambia in the top left quadrant and Lake Kariba, on the border between Zambia and Zimbabwe, in the top right quadrant.

The Barkly Tableland in the northeastern part of Australia’s Northern Territory is home to several lakes, including (from left to right) Lake Woods, Lake Tarrabool, Corella Lake and Lake Sylvester. The latter two are closely clustered together and thus appear as one large lake in this image.

These lakes on situated on the westernmost edge of the Barkly Tableland. Their volume and surface area fluctuate depending on the rainfall in the region. Please click here to see an image from five months earlier in which the lakes appear larger and the surrounding area is green with vegetation.

When precipitation levels are high and Lake Tarrabool is completely flooded, it is the largest wooded swamp in tropical Australia. Its swampland provides an important breeding area for waterfowl.
