                                         | This dataset has been collected thanks to the long-term partnership with Department of Agricultural Land Management (DALaM), Lao PDR, which granted the permission for field access, and to the financial, scientific, technical, and/or logistical support of the Multiscale TROPIcal CatchmentS (SNO M-TROPICS; https://mtropics.obs-mip.fr/) critical zone observatory (previously MSEC).
   This .csv dataset includes Escherichia coli concentrations (MPN 100 mL-1) with upper and lower limits of the confidence interval, and physico-chemical measurements in stream water. Physico-chemical measurements include temperature (°C), electrical conductance (µS cm-1) at 25 °C, dissolved oxygen concentration (mg L-1) and saturation (%), pH (-), oxidation-reduction potential (mV), turbidity (NTU), suspended sediment concentration (g L-1). All variables were measured in the Mekong River in Luang Prabang (MK_17) and in five tributary catchments of the Mekong (Nam Khan: stations NK20 and NK26; Houay Khan: A6; Nam Ou: Nou_1; Nam Seuang: Nse_1), in northern Lao PDR. The monitoring includes measurements during low flow and high flow periods from May 2011 to May 2021.
