Watercourse

la Loire

16 monitoring stations on this water in France, holding 14,663 values between 1900 and 2026. The publisher names the water this gauge sits on without stating what kind of watercourse it is, so neither does Hydrionis.

The monitoring network on this water

Hydrionis holds 14,663 values from 16 gauges on this water. Discharge is a property of a gauge and its reach, not of this water as a whole, so this page reports the network and its records rather than a single figure.

What this record holds

Hydrionis decides which waters get a page, and which of those are offered to search, from what is actually held rather than from how the page reads. Five signals are counted; this record has 3 of them, which makes it a full profile.

Where these figures come from

MeasuredHigh confidenceJuly 2026

Source: Hub'Eau — Hydrométrie — French river flow and stage, M5300010. Licence: Open — attribution required (attribution required).

Method: Monthly mean discharge (QmM) computed by the publisher from its validated sub-hourly record, reported in litres per second and converted to cubic metres per second on ingestion. Where a site has been measured by more than one station, the station with the longest published series is used rather than blending stations whose values for the same month can differ.

Measured on la Loire.
