Lake Chad and Nearby Marshes, Chad, Nigeria and Niger13.3N 14.1E
Lake Chad, visible as a green area at the right edge of this image, is a historically large, shallow, endorheic lake in Africa, whose size has varied over the centuries. According to the Global Resource Information Database of the United Nations Environment Programme, it shrank as much as 95% from about 1963 to 1998; yet it also states that recent satellite images show significant improvement over previous years.
Lake Chad is located mainly in the far west of Chad, bordering on northeastern Nigeria. The Chari River, fed by its tributary the Logone, provides over 90% of Lake Chad’s water, with a small amount coming from the Yobe River in Nigeria/Niger. Despite high levels of evaporation the lake is fresh water. Over half of the lake’s area is taken up by its many small islands, reedbeds and mud banks, and a belt of swampland across the middle divides the northern and southern halves while the shorelines are largely composed of marshes.
