Mekong River Monitoring

Last Week’s Situations

According to MRC’s observed water level (WL) at Jinghong showed decreasing about 0.70 m from 535.93 m on 18 Jan to 535.23 on 24 Jan 2022 (recorded on 7:00 am) and stay about 0.34 m lower than its two-year average (2020-2021) value.

Last week, from 18 to 24 Jan, WLs along the lower Mekong River in Thailand’s Chiang Saen were decreased about 0.18 m but remained 0.35 m higher than its long-term average (LTA), considered as normal. WL at Lao PDR’s Luang Prabang was nearly stable compared with last week and stay close to its than historical maximum value. WLs at the monitoring stations from Chiang Khan to Vientiane in Thailand and Lao PDR significantly increased 1.48 m and 0.68 m respectively. The current WL at Vientiane in Lao PDR is about 0.02 m higher than its historical maximum level, which considered critical. WLs from Nong Khai in Thailand to Paksane in Lao PDR are increased in between 0.39 m and 0.76 m but still about 0.22 m and 0.55 m respectively lower than their LTA value. WLs at Thailand’s Nakhon Phanom to Savannakhet in Lao PDR increased about 0.10 m and remained staying below their LTA levels. WL at Savannakhet in Lao PDR is close to its historical minimum level, which considered very critical. WL from Khong Chiam in Thailand to Pakse in Lao PDR increased about 0.06 m and still about 0.13 m lower than their LTA level. WLs in Cambodia’s Stung Treng to Kratie decreased 0.05 m and stay about 0.12 m and 0.10 higher than their LTA value. From Kompong 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 between their Maximum and Minimum levels at Chau Doc, due to daily tidal effects from the sea and considered as critical.

Next week’s Situations

Next week, from 25 to 31 Jan 2022, WLs along the lower Mekong River from Thailand’s Chiang Saen will decrease about 0.30 m but continue to stay slightly higher than its LTA, while WL at Lao PDR’s Luang Prabang will continue to stay close to its Maximum level. From Thailand’s Chiang Khan to Lao PDR’s Paksane will decrease from 0.02 m to 0.40 m. WLs from Nakhon Phanom in Thailand to Pakse in Lao PDR will increase about 0.35 m and continue to stay below their LTAs. From Cambodia’s Kompong Cham to downstream at Neak Luong will 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 in between their LTAs and Maximum values, effected by the tidal process.

Data & Information

Data and information are key to sustainable water resources management. The MRC has a long history of data collection and analysis about the heath and conditions of the Mekong River, with some data over 100 years. The interactive dashboards assemble and visualise more than 10,000 datasets covering historic and current assessment covering hydrology, sediment, water quality, fisheries, ecological health, climate change, and flood and drought.
