Who provides data to the Hydro data bank?

It is mainly state departments, regional offices of Environment, flood forecasting services, departmental directorates for agriculture and forestry, water agencies, but also Electricité de France or research organization (CEMAGREF, universities, ...), as well as landscaping companies (la Compagnie d'aménagement des coteaux de Gascogne, la Compagnie nationale du Rhône, la Société du canal de Provence, la Compagnie d'aménagement du Bas-Rhône-Languedoc...).

These data producers install monitoring stations in the river, ensuring their maintenance, collect data, and check the feed the data bank. They make the gauging right at measuring stations and establish calibration curves that are also in the data bank. Then they validate and possibly correct the data. They are responsible for and ensure the data quality.

The Central Hydrometeorological Service and Support to Flood Forecasting Service (Ministry of Ecology and Sustainable Development) located in Toulouse, administers and manages the data bank services related to HYDRO. It also ensures the changes.
