Survey on the use of federal hydrological data and information
The Federal Office for the Environment (FOEN) is conducting a survey to find out more about the use of federal hydrological data and information. The aim is to further improve the FOEN's services in the field of hydrology and water management and to tailor them to the needs of users. Thank you for your support!
The survey is anonymous and takes approximately 10 minutes to complete. We would be delighted if you could take the time to complete the online survey (in German or French). You can participate until 2 November 2025.
