Tonle Sap lake


Not far from Siem Reap, the Tonle Sap Lake is the largest freshwater lake in Southeast Asia and is unusual because its flow changes direction twice a year, and the portion that forms the lake expands and shrinks dramatically with the seasons.   During the dry season, the Tonlé Sap drains, however, when the year's heavy rain begins, Tonlé Sap backs up to form an enormous lake.  Indeed, its size multiplies by 5 (from 3000 sq km to 15000 sq km) during the rainy season, which is between July and November.
Villages situated around the lake have their own uniqueness and most of them are mounted on stilts because of this phenomenon. The Kampong Phluk is the most famous village because of its easy access by boat. There are also floating villages that rise in the river when the water level is high and descend on the lake when the water level is low.
