## Notes for language models

- Discharge values are observed where a gauge sits on the river and interpolated
  between gauges; estimated values (from drainage area x local specific discharge)
  are labelled as estimates and must not be cited as measurements.
- Each gauge value carries its own observation date; the dataset build time and
  page generation time are stated in every page footer and in the JSON datasets.
- Localized river names (major/transboundary rivers) are curated; the long tail
  keeps its canonical English name in every language.
- Geometry: HydroRIVERS v1.0 (HydroSHEDS), European reaches >= 500 km2 catchment.
- Data belongs to the cited national hydrology providers; check their licences
  before redistribution.
