Lake Kariba as seen by Envisat

The narrow, man-made Lake Kariba, located along the border of Zambia and Zimbabwe, as seen by Envisat. Lake Kariba was created in the late 1950s by the construction of a largest dam wall across the Zambezi River running through the Kariba Gorge.
Today Lake Kariba is one of the largest dams in the world, with a surface area of 5580 square kilometres and an average depth of 29 metres, increasing to a maximum of 97 metres. It is 220 km long and in places up to 40 kilometres wide.
The Medium Resolution Imaging Spectrometer (MERIS) acquired this image on 6 June 2005, operating in Full Resolution mode with a spatial resolution of 300 metres. It covers an area of 672 by 672 kilometres.
