What is Tonle Sap?
Tonle Sap is the largest freshwater lake in South East Asia. It is an unique ecological water system which is designated as a UNESCO biosphere. During the monsoon season, the Mekong River reverses its flow and pushes rain water back into the lake so Tonle Sap’s dimensions change every wet season from 2, 700 sq km with about a meter in depth to as much as 16, 000 sq km with a depth up to 9 metres.
The seasonal flood provides a great breeding ground for fish so it’s not surprising that about 75% of annual inland fishing catch comes from Tonlé Sap and supports more than 3 million people. The lake is one of world’s most productive inland fisheries.
