Mekong River Monitoring

Last Week’s Situations

Last week, Nov 24-30, water levels (WLs) along the lower Mekong River in Thailand’s Chiang Saen slightly increased below their long-term averages (LTAs), but decreased at Thailand’s Chiang Khan and Lao PDR’s Luang Prabang due to the influence of Xayaburi dam operations. WLs decreased and dropped below their LTAs at the monitoring stations from Vientiane to Pakse in Lao PDR and Thailand. WLs at Lao PDR’s Paksane decreased below its minimum levels, considered as critical. This low water level is probably due to the influence of Nam Ngum dam operation. WLs in Cambodia’s Stung Treng 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 decreasing below their LTAs due to daily tidal effects from the sea.

Next Week’s Trends

Next week, Dec 1-7, WLs along the lower Mekong River from Thailand’s Chiang Saen to Lao PDR’s Vientiane will slightly increase but remain under their LTAs, except at Paksane in Lao PDR, the water levels at this station are only at its historical minimum levels. Water levels from Nakhon Phanom to Pakse in Lao PDR and Thailand will drop below their LTAs, and from Cambodia’s Stung Treng to Neak Luong on the Mekong River and Chaktomuk to Koh Khel on the Bassac River will decrease below their LTAs. For the tidal stations at Vietnam’s Tan Chau and Chau Doc will likely decrease below their LTAs, 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.
