What this classification means

WFD code removed 2026-06-18: prior id PLRW20002145234 was a fabricated stub (no such code in EEA WISE). Cannot re-map yet — the venue coordinate (52.75432, 17.78456) is in Wielkopolska near Gniezno, NOT on the Wda (which runs through Pomerania / Bory Tucholskie, ~53.5–54°N). The coordinate is wrong; fix the venue location first, then re-map to a Wda reach (e.g. PLRW200011294531 … PLRW20001129499). Source: EEA WISE SWB_SurfaceWaterBody (discodata.eea.europa.eu).
