Image Caption: Once a great inland lake, Lake Chad (13.0N, 14.0E) in the Sahara Desert at the intersection of the African nations of Chad, Niger, Nigeria and Cameroon, is now in decline. The larger northern lobe is almost totally dry and slowly filling in with encroaching sand dunes. The southern lobe, still retains some water in the lower center but the water surface area is less than 2000 square kilometers and sand dunes are filling in the north end.
