## Gauging stations on the Loir

The following 3 gauging stations report discharge for the Loir, ordered downstream (largest catchment first). Discharge is in cubic metres per second (m³/s).

| Station | Country | Discharge (m³/s) | Historical Comparison | Observed | Measurement | Data quality | Provider | Lat, Lon | Source |

## Data, sources & timestamps

Geometry is the HydroRIVERS network (HydroSHEDS): European reaches with at least 500 km² of upstream catchment, merged into chains between confluences. Flow direction comes from the network itself; river names are the canonical English label joined from provider metadata and Natural Earth, with local-language aliases retained.

Discharge is normalised observed streamflow from official national hydrology providers, measured where a gauge sits on the river and interpolated between gauges. Pale/estimated values are derived from drainage area × the local specific discharge of nearby gauges and are never presented as measurements.
