Assessment of the State of the Inland Surface Water Pollution Monitoring Station Network of the Roshydromet State Observation Network in 2018–2023

The paper presents the data for 2018–2023 on the changes in the parameters of the state of the network of regular observations on inland surface water pollution, which is included in the Roshydromet state observation network. The main trends in the number of observation stations, watercourses, and reservoirs they are located on are identified. The distribution of observation stations by categories, the number of the samples taken and the indicators determined are estimated. The water quality of transboundary river sections located on the border with 12 states is assessed, and the most stressed areas are identified.
