Situation Report on Dry Season Hydrological Conditions in the Lower Mekong River Basin: November 2020–May 2021

This Situation Report presents a preliminary analysis of the Lower Mekong River Basin hydro-meteorological conditions over the 2020–2021 dry season. It shows fluctuations in water levels in the upper reaches of the Mekong mainstream in Lao PDR and Thailand, as well as low water volume stored in the Tonle Sap Lake. Rainfall in April–May was the highest on record for these months for the last 18 years in places. Overall, flows in the Mekong in the first five months of 2021 were also higher than the long-term average, except for December 2020 where flows in the Mekong mainstream were closer to normal. But river flows did not increase significantly.

Situation Report on Hydrological Conditions in the Lower Mekong River Basin in July–December 2020

The report presents a preliminary analysis of the hydro-meteorological conditions in the Lower Mekong River Basin (LMB) in July–December 2020. The report suggests that the LMB experience a second year of low flows at the beginning and a delayed onset of the wet season in 2020, with some parts experiencing low flows and appearing to be worse than that in 2019.
