Tonlé Sap During Middle of Dry Season, Cambodia12.9N 104.0E
This APM image shows the western part of the Tonlé Sap (loosely translated as “Great Lake”) and surrounding floodplain. The Tonlé Sap is the largest freshwater lake in South East Asia, and is part of a complex lake and river system.
The Tonlé Sap is unusual for two reasons: its flow changes direction twice a year, and the portion that forms the lake expands and shrinks dramatically with the seasons. From November to May, Cambodia’s dry season, the Tonlé Sap drains into the Mekong River at Phnom Penh. However, when the year’s heavy rains begin in June, the Tonlé Sap backs up to form an enormous lake. This image shows the lake towards the middle of the dry season.
