According to MDM (Mekong Dam Monitoring Project), most of the Mekong River basin is experiencing extreme drought, especially in the upper basin, the Golden Triangle region and parts of Laos.
Rainfall was generally low across the Mekong River basin. In addition, dam storage caused the Mekong River along the Thai-Lao border to be about 1 meter lower than normal. The Mekong River in Cambodia fell to about 1.5 meters below normal and the Tonle Sap Lake was about 2 meters lower.
Storm No. 1 in the East Sea is heading towards the mainland, the northern provinces of our country.

Currently, the flooded area of the entire Mekong Delta is about 5,500 km2 , only 37% of the normal level at this time of year.
According to the Southern Institute for Water Resources Planning (SIWRP), the water level on the Mekong mainstream is low and has been on a slight downward trend over the past week. As of July 15, at Kratie station, the water level was measured at 10.67m; 3.46m lower than the average of many years and 0.58m and 1.26m lower than 2015 and 2019, respectively.
Water levels in the Mekong Delta are also low and fluctuate strongly with the tides. Water levels at Tan Chau station have been decreasing over the past week with an average rate of 8cm/day. The highest water level on July 14 was 1m, 0.79m lower than the average of many years; 0.16m lower than in 2015, and 0.08m lower than in 2019.
At Chau Doc station on July 14, it reached 1.17m, 0.44m lower than the average of many years; 0.07m lower than 2015, 0.02 lower than 2019.
Storm No. 1 (Talim Storm) approaches Vietnam, will cause strong winds 'unseen in many years'
In a special bulletin related to storm No. 1 - Talim, SIWRP said: According to the forecast of the US National Oceanic and Atmospheric Administration (NOAA), the rainfall in the lower Mekong River region in the next 6 days will not be high due to the little influence of storm No. 1's circulation in the East Sea. The highest rainfall will be concentrated in the Laos region on July 16-17, with a common amount of 20-40mm. The following days will decrease, commonly at 10-20mm.
SIWRP concludes: Rainfall due to the impact of storm No. 1 occurring in the lower Mekong River basin is at a low level. Therefore, it is assessed that the water source on the Mekong mainstream in the coming time will tend to increase slightly, the water level at Kratie station is forecast to decrease in the next 4 days and then increase again. The water source of the Mekong River upstream is assessed to increase in the coming time following the trend of increasing high tides, flooding in the Mekong Delta will increase slightly and change strongly according to the tide.
