Hydrological bulletin of the Federal Office for the Environment FOEN
The Federal Office of the Environment (FOEN) provides semiweekly (on Monday and Thursday) information about the current hydrological situation and developments expected in subsequent days. During particular events, the bulletin is published more frequently. This medium is not used to diseminate flood warnings.
The bulletin is only available in German and French. During particular
events in Italian-speaking Switzerland, the bulletin will also be
published in Italian.
