The river water masses are derived from the BDCarthage® v3 hydrographic theme of the BDCarto®. The criteria for the realisation of the masses d'river water are: — A body of water belongs to a single hydroecoregion — The dominant fish settlement based on the fish context (Salmonicole, cyprinicole, Intermediate) — Size class (strahler confluence row) The code of mass d'water is structured as follows: Mass type code d'water + Basin code (district as defined in dce) + Increment Correspondence report DCE: this entity corresponds to WISE’s River Water Body (RWBODY) concept. __Origin__ The data are collected from the different DCE Basin __Partner organisations__ Ash, Agence de l'eau Adour-Garonne, Agence de l'eau Artois-Picardie, Agence de l'eau Loire-Bretagne, Agence de l'eau Rhine-Meuse, Agence de l'Rhone-Méditerrannée water and Corsica, Agence de l'eau Seine-Normandie __Links annexes__ * [see documentation on Sandre website](http://www.sandre.eaufrance.fr/squelettes/consulter_fiche_entite.php?dictionnaire=/db/sandre/Schemas/mdo/1.3/sandre_fmt_xml_mdo.xsd&entite=MasseDEauRiviere) [See this page on geo.data.gouv.fr](https://geo.data.gouv.fr/fr/datasets/8ae9c15f0771a1148d0a82d06b7d77ecb332ae91)
