NewsArea variation of Lake Tonlé Sap (Cambodia)

Lake Tonlé Sap is a fresh water lake in Cambodia. During rainy season (from May to October), the water area of the lake expands to more than 3 times as large as in dry season (from November to April). Fig. 1 shows Lake Tonlé Sap observed by TANSO-CAI in 2016. The lake gradually expanded from August. The water level also rose up to about 10 m in addition to expanding of the water area.
This is a natural phenomenon that occurs every year. It generates planktons and makes a good fishing place. Therefore, people who live in this region adapted to this change, such as living on the water and operating a fishery.
