Climate Change’s Affects on Lake Kariba, Zimbabwe

16.9S 27.7E

March 30th, 2013 Category: Climate Change, Lakes

Zimbabwe – March 29th, 2013

Rainfall around Lake Kariba (lower left quadrant), in Zimbabwe, is decreasing at a rate of 0.63 mm per year, while evaporation rates have increased by 31% at an average rate of 2.77 mm per year since 1963. Also, the temperatures around the Kariba area have been rising since 1964. All these climatic factors have led to decreasingly water levels and nutrients, and consequently to a decrease in the lake’s fish population (click here for more information).

Zimbabwe and Zambia - March 1st, 2012

Lake Kariba is the world’s largest artificial lake and reservoir by volume. It lies 1300 kilometers upstream from the Indian Ocean, along the border between Zambia and Zimbabwe. Lake Kariba was filled between 1958 and 1963 following the completion of the Kariba Dam at its northeastern end, flooding the Kariba Gorge on the Zambezi River.

Lake Kariba is over 220 kilometers (140 mi) long and up to 40 kilometers (20 mi) in width. It covers an area of 5,580 square kilometers (2,150 sq mi) and its storage capacity is an immense 185 cubic kilometers (44.4 cu mi). The mean depth of the lake is 29 meters (95 ft); the maximum depth is 97 meters (320 ft). It is the world’s largest human-made reservoir. The enormous mass of water (approximately 180,000,000,000,000 kilograms, or 180 petagrams [200 billion tons]) is believed to have caused induced seismicity in the seismically active region, including over 20 earthquakes of greater than 5 magnitude on the Richter scale.

Zambia and Zimbabwe - April 15th, 2011

Lake Kariba’s irregular shoreline stands out thanks to its dark waters in contrast with the green of the surrounding landscape. The lake is located on the Zambezi River on the border between Zambia (above) and Zimbabwe (below).

The bright green area in the upper part of the image is part of two national parks: Blue Lagoon National Park and Lochinvar National Park, separated by the Kafue River. The northern side of the parks is in the Zambezian and Mopane woodlands ecoregion and the southern parts  are in the Zambezian flooded grasslands ecoregion.

Also visible near the top edge in the upper right quadrant is Lusaka, the capital and largest city of Zambia, appearing here as a tan circular area. It is located in the southern part of the central plateau, at an elevation of about 1,300 metres (4,265 feet).

Zambia and Zimbabwe - March 31st, 2011

By volume, Lake Kariba is the largest artificial lake and reservoir in the world. It is located on the Zambezi river, about halfway between the river’s source and mouth, about 1300 kilometers upstream from the Indian Ocean, and lies along the border between Zambia and Zimbabwe.

While Lake Kariba is dark blue and mostly free of sediments in this image, another lake can be seen to the east in the full image that is quite tinged by sediments: the Cahora Bassa Lake. Africa’s fourth-largest artificial lake, it situated in the Tete Province in Mozambique.

Botswana - August 5th, 2010

The upper half of this image has a greenish tone, in contrast with the brown hues of the Kalahari Desert. The Okavango River empties its waters onto those desert sands towards the center of this image, creating a green inland delta known as the Okavango Delta, in Botswana.

East of the delta are two other interesting features: the Makgadikgadi Pan, a large salt flat in Botswana that appears bright white, and Lake Kariba, a dark blue on the Zambezi River that lies along the border between Zambia and Zimbabwe.
