Tonle sap lake

ឺorld, supporting over 3 million people and providing over 75% of Cambodia's annual inland fish catch and 60% of the Cambodians' protein intake. At the end of the rainy season, the flow reverses and the fish are carried downriver.The receding waters also leave nutrient rich deposits of sediment in the surrounding area creating prime agricultural land for the rest of the year.The reversal of the Tonle Sap river's flow also acts as a safety valve to prevent flooding further downstream.The lake occupies a depression created due to the geological stress induced by the collision of the Indian subcontinent with Asia.
