Mekong River Monitoring

Last Week’s Situations

According to MRC’s observed water level (WL) at Jinghong showed decreasing about 0.58 m from 535.81 metre (m) on 16 Nov to 535.23 on 22 Nov 2021 (recorded on 7:00 am) and stay about 0.36 m lower than its two-year average (2020-2021) value. Last week, from 16 to 22 Nov, WLs along the lower Mekong River in Thailand’s Chiang Saen increased about 0.18 m and still approximately 0.61 m lower than its long-term average (LTA), considered as critical. WL at Lao PDR’s Luang Prabang was increased about 0.42 m compared with last week and stay about 1.75 m higher than its LTA. WLs at the monitoring stations from Chiang Khan to Paksane in Thailand and Lao PDR increased about 0.30 m and still stay below their LTA values. WL at Lao PDR’s Nakhon Phanom in Thailand to Pakse in Lao PDR also increased about 0.25 m but still below their LTA levels. WLs in Cambodia’s Stung Treng to Kratie are higher than their LTA values, but from Kampong Cham to Neak Luong on the Mekong River, Chaktomuk to Koh Khel on the Bassac River and Prekdam on the Tonle Sap River decreased below their LTAs. For the tidal stations at Viet Nam’s Tan Chau and Chau Doc, WLs fluctuated in between their LTAs and Minimum levels due to daily tidal effects from the sea.

Next week’s Situations

Next week, from Nov 23 to 29, WLs along the lower Mekong River from Thailand’s Chiang Saen will decrease about 0.10 m and still stay below its LTA, while WL at Lao PDR’s Luang Prabang will continue to stay higher than its LTA level. From Thailand’s Chiang Khan to Lao PDR’s Vientiane will increase about 0.40 m, follow the same trends from upstream and remain match and stay below with their LTAs. WLs from Nakhon Phanom to Pakse in Lao PDR and Thailand will increase about 0.20m but still below their LTAs. From Cambodia’s Kampong Cham to downstream at Neak Luong will continue to decrease and will stay below their LTAs. From Chaktomuk to Koh Khel on the Bassac River and Prekdam on the Tonle Sap River will decrease below their LTAs. For the tidal stations at Viet Nam’s Tan Chau and Chau Doc will likely fluctuate below their LTAs, effected by the tidal process.
