The Tonle Sap Lake (TSL) is among the most productive freshwater ecosystems, and one of the most fish-abundant lakes in the world. It is connected with the Mekong River by the Tonle Sap River. The TSL absorbs a huge volume of water, which helps to reduce flooding in the Mekong River floodplains during the peak flooding season, then releases water...
