Tonle Sap Lake is unique in its ecological and cultural importance. In the rainy season, water flows upstream from the Mekong River to swell the lake to 4 times its dry-season extent, creating extensive shallow water habitat for fish. When the lake drains back to the Mekong through the Tonle Sap River, it creates one of the greatest fishing grounds of the world, providing protein to millions of people. Research by former Riverlab/Fulbright visiting scholar Chantha Oeurng and his student Ty Sok demonstrates evolving flow and sediment relations between the lake and the Mekong River. The just-published paper, Assessment of Suspended Sediment Load Variability in the Tonle Sap and Lower Mekong Rivers, Cambodia, is available for free download until late May from Catena here.
