Description: INSPIRE - Annex III Theme Environmental Monitoring Facilities - WFD monitoring network SWB (2021-2026) - Network of measurement stations for the period from 2021 to 2026, established as part of the surface water quality monitoring program in accordance with the Water Framework Directive (2000/60/EC). The measurement network includes two components: the surveillance control network and the operational control network. The results of this monitoring program (2021-2026) were used for assessing the state of surface water bodies within the framework of the 4th management plan. Physico-chemical parameters as well as chemical parameters are sampled at the same station. The location of biological parameter measurement stations may vary slightly.
