Tonlé Sap
The Mekong now stands higher than the lake, so the Tonlé Sap river runs backwards and pumps water in. Fish move upstream into the lake to spawn. This is when the lake expands fastest.
Mekong basin rainfall: 39 mm over the past 72 hours, 30 mm forecast for the next 72.
This is a seasonal estimate combined with basin rainfall, not a measured level. Official water level and discharge come from the Mekong River Commission (MRC). The timing of the reversal varies year to year and has shifted noticeably over the past two decades.
