Water quality (WFD)
  • Ecology: Moderate
  • Chemical: Failing to achieve good
What this classification means

WFD re-coded 2026-09-14 after the pin audit: matched by point query against EEA WISE WFD2022_SurfaceWaterBody (the river water body whose line lies 3 m from the venue pin). Status: WISE 2022 (3rd RBMP) ecological class 3 = Moderate, chemical 'failing to achieve good' (Austria-wide in the 2022 cycle). Prior id ATOK402210000 (Moderate) described a different reach.
