Mangoky River and Lake Ihotry, Southwestern Madagascar21.7S 43.3E
Several rivers are visible along the central- and south-western coast of Madagascar, emptying tan sediments into the Strait of Mozambique. One of the most prominent of these rivers is the Mangoky, whose mouth is situated northwest of a greenish lake.
This greenish body of water is Lake Ihotry, a closed saline lake in the semi-arid southwestern part of Madagascar. Its area varies seasonally, from 96 km² to 112 km².
