Tonle Sap Lake in the Lower Mekong Basin

The Tonle Sap Lake (known also as the Great Lake), located in central Cambodia, is the largest freshwater lake in Southeast Asia and an important component in the Mekong River system. The area is globally unique and the lake has an extraordinary hydrological system. During the wet season, the Tonle Sap River changes its direction to flow into the Tonle Sap Lake instead of from the lake, due to heavy flooding of the Mekong River.
