Water quality (WFD)
  • Ecology: Poor
  • 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 23 m from the venue pin). Status: WISE 2022 (3rd RBMP) ecological class 4 = Poor, chemical 'failing to achieve good' (Austria-wide in the 2022 cycle). Prior id ATOK900410004 (High) described a different reach.
