Lake Chad (Arabic: بحيرة تشاد, Kanuri: Sádǝ, French: Lac Tchad) is an endorheic freshwater lake located at the junction of four countries: Nigeria, Niger, Chad, and Cameroon, in western and central Africa respectively, with a catchment area in excess of 1,000,000 km 2 (390,000 sq mi). It is an important wetland ecosystem in West ...
This list is restricted to open bodies of fresh-water over 5 ha in area, because of the difficulty in establishing what is a pond and what is a lake.. It excludes service reservoirs used within the water supply network for the storage of drinking water and excludes water bodies on industrial sites used exclusively for industrial purposes (works ponds).
The Chad Basin is the largest endorheic basin in Africa, centered approximately on Lake Chad. It has no outlet to the sea and contains large areas of semi-arid desert and savanna . The drainage basin is approximately coterminous with the sedimentary basin of the same name, but extends further to the northeast and east.
The seventh largest lake in the world (and the fourth largest in Africa), Lake Chad is located in the sahelian zone, a region just south of the Sahara Desert. [6] The Chari River contributes 95 percent of Lake Chad's water, an average annual volume of 40 billion cubic meters, 95% of which is lost to evaporation. [6]
The map shows the locations of the lakes with a volume over 4 x 10 6 m³ and gives an indication of the volume of water in each lake. The markers suggest this by showing the size of a drop of water where the volume of the drop would be in proportion to the quantity of water in the lake (the diameter of the drop is proportional to the cube root of the lake's volume).

There are 120 Natural Areas in England ranging from the North Pennines to the Dorset Heaths and from The Lizard to The Fens. They were first defined in 1996 by English Nature and the Countryside Commission, with help from English Heritage. They produced a map of England that depicts the natural and cultural dimensions of the landscape. [3]
