Lake, western Cambodia.
The largest freshwater body in mainland Southeast Asia, it receives several tributaries as well as the floodwaters of the Mekong River . During the rainy season its area increases from 1,000 sq mi (2,600 sq km) to about 9,500 sq mi (25,000 sq km). At low water it is little more than a reed-infested swamp, with channels for fishing craft. A large carp-breeding and carp-harvesting industry there supports numerous floating fishing villages. The ruins of Angkor lie near its northwestern shore.
