Tonle Sap Lake, Cambodia

Tonle Sap Lake  is one of the world's largest fresh water bodies of water in the world.  It is created from the convergence of several rivers of South East Asia including the Mekong.  It is used by the locals as a major fishing area as well as a place for floating houses that can be moved depending on the floods and draughts.  This lake was also historically one of the waterways used by the Ancient Champa society of the lower Mekong to invade the Khmer Empire when the river anually reversed direction.  Children are taught an early age to swim and boat in this waterworld.
