This dataset published by the Système d'information du territoire à Genève (Geneva territorial information system) inventories regulation structures located in watercourses in the canton of Geneva, Switzerland. Alongside general civil-engineering information, each record includes an assessment of the structure's ecological impact on the environment. Entries are generally illustrated with a photograph of the structure. The layer supports local water-management and environmental-monitoring purposes.Cette couche recense les ouvrages de régulation situés dans les cours d'eau. Aux informations générales de génie civil s'ajoute une évaluation de l'impact écologique de l'ouvrage sur l'environnement. En général une photo illustre l'ouvrage.
