The Chinit ( Stung Chinit , also written Chinith ) is a river in Cambodia in the Kampong Thom province . It is an important outflow of the Tonle Sap ("big lake") and has a length of 264 km. With 4,504 km² it has the third largest catchment area of ​​the rivers around the Tonle Sap Lake, which has an annual rainfall of approx. 1,500 mm. The average runoff is estimated at 6,711 m³ / s. The main tributaries are the Kambot , the Slap and the Tang Krasang . What is unusual is that the river flows in a loop at Kampong Chhnang in the Kampong Chhnang province back into the main outflow of the lake, the Tonle Sap of the same name , which flows to the Mekong and the Mekong Delta .

The prehistoric excavation site of Samrong Sen is on the bank of the river. Water resource projects that began in 1971 and 2003 had varying degrees of success.

The sub-basins of the rivers around Tonle Sap Lake

Inland navigation is only practiced to a very limited extent due to the shallow depth of the river. Riverside residents use fishing and community boats to transport goods to markets; the river is thus an important trade route.

The chinite has been the subject of studies on fish migration. For this purpose, samples of larvae and juvenile fish were taken in sections 20 to 50 km upstream in the Chinit and four other rivers in the floodplains of the Tonle Sap Lake. In Chinit 71 species have been recorded from four types. It was found that the species in the five rivers were different, but identical in the tributaries of the Chinit .
