La Dordogne — monitoring and records

The monitoring network on this water

Hydrionis holds 6,580 values from 7 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.

The seasonal shape

An annual mean says how much water a river carried. A monthly record says when — and on most rivers the difference between a wet winter and a dry summer is larger than the difference between one year and the next.

Monthly mean flow at La Dordogne à Cénac-et-Saint-Julien

Each month's mean discharge as the publisher computed it, which shows the seasonal shape an annual mean flattens away. 1900–2026.

Show relevant events (1 event)Shading marks when something was recorded, not what caused the line.

Taken as the publisher computes it rather than recomputed by Hydrionis from daily values: the publisher knows which of its readings passed validation. Months the gauge did not cover are absent rather than interpolated, and the line breaks where they fall.

What the shaded periods are (1 event)

A shaded period marks when something was recorded, not what caused the shape of the line. Where the two coincide, they coincided.

Documented record — A documented event, compiled from cited sources after it happened. The dates are as good as the record, which for older events can mean the month rather than the day.

About this series

Everything below is a property of the data rather than a rating of it. There is deliberately no single confidence score: how much a gap matters depends on what you are about to do with the series, and only you know that.

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.

Attribution and citation

Attribution you are required to give

These are conditions of the licences the underlying data is published under. They are obligations to the publishers, not to Hydrionis, and they apply to you directly whether or not you mention Hydrionis at all.

Suggested citation for Hydrionis

Hydrionis (2026), La Dordogne gauge records, accessed 2026-10-05, hydrionis.com/waters/france-la-dordogne/

Cite Hydrionis where you rely on the compilation, the normalisation, the eligibility judgements or a chart. Where you use an unmodified published value, the publisher’s attribution is the one that is required; crediting Hydrionis as well is welcome and is not something Hydrionis can require of you.

Recommended, not required. Hydrionis does not claim rights over unmodified public data it relayed, and doing arithmetic on somebody else’s measurements does not make them Hydrionis’s. Cite the version and the access date: the La Dordogne gauge records changes as publishers release and as methods are revised, and a citation without both cannot be checked later. Full guidance is on cite and reuse.

Where these figures come from

Source: Hub'Eau — Hydrométrie — French river flow and stage, P2380010. 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 as they are collected. 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 Dordogne.
