Tonle Sap River

The Tonle Sap River in Cambodia.

The Tonle Sap River water flows upstream and sometimes downstream.

Tonle Sap is Cambodia's largest lake cum river situated located between Siem Reap and Phnom Penh.Tonle Sap in the dry season is only a shallow lake that supplies water to the Mekong River near Phnom Penh in the capital Phnom Phen the stream flows along the Kings Palace and the riverfront along Sisowath Quay.

During monsoon times the high water level of the Mekong River pushes a reverse flow up the Tonle Sap River into the lake. This up flow expands the size of the lake from around 2500 square kilometers at dry season to over 10,000 square kilometers at rainy season. This way Tonle Sap Lake becomes the largest freshwater lake in South East Asia during the monsoon seasonThe mangrove forest around the Tonle Sap Lake shores are home for water birds, several hundred species of fish plus crocodiles and turtles. Cambodian and Vietnamese communities are living in the Tonle Sap floating villages, mainly on the shores of the lake. The floating villages are quite autonomous with their floating houses, markets and community services The inhabitants of the Tonle Sap floating villages make a living from fishing with fish traps. Their Tonle Sap fish catch supply Cambodia with about half of the fish for consumption If you're are out for a lake or river cruise on the Tonle Sap and coming from the Siem Reap area the floating villages of Chong Khneas is your starting point.
