Floods in the Mekong Delta's upstream will recede rapidly in November.

According to the Southern Institute of Water Resources Research , the upper Mekong River basin is currently at the end of the flood season, the water level in Tonle Sap Lake and the headwaters of the Mekong River at Tan Chau is peaking, followed by a period of flood receding and inundation due to high tides.

The storage deficit of reservoirs in the Mekong River region is currently about 15 billion m3. The storage of Tonle Sap Lake is about 2.25 billion m3 lower than the average of the period 2010-2022. The total flow forecast from now until the end of November 2023 to the Mekong Delta (via Kratie) is about 40-60 billion m3. In the coming time, reservoirs in the Mekong River basin will continue to accumulate more water until the end of the year, so the flood level in the upstream area and the Mekong River basin in general will decrease rapidly and be lower than at the beginning of the dry season in 2023-2024.

In November 2023, the flood in the Mekong Delta will recede rapidly, but the water levels in the areas along the Tien and Hau rivers will rise again during the high tides at the end of the year; notably the high tide from November 14-16 with a peak at approximately the same level and higher than the peak tide in early and mid-October. The highest daily water level in the central region of the delta at My Thuan station (Tien river), Can Tho (Hau river) always remains higher than 1.6m throughout November.

Therefore, people need to proactively build embankments and drain water when the tide is low or proactively pump out water to ensure planting of the 2023-2024 Winter-Spring rice crop.
