The FOEN operates an extensive network of hydrometric stations. The stations measure various parame-ters in Swiss watercourses and water bodies, for example water status, runoff, sediment transport rate, temperature and various physical and chemical properties of the water. The records, some of which go back to the 19th century, are available both on paper and in digital format. We compile data suitable for the resolution of your problem from this comprehensive archive.
Station lists provide you information on the status, measuring period, and measurement quantities of individual stations.
Measurement rows from operating stations are recorded up to the current year. However, verified but provisional digital data can usually be delivered after about 20 days. These data can also be retrieved in table form (pdf) via the Internet after about 20 days. Depending on the station, provisional and unverified data from the last seven to 40 days can be found as graphics on the Internet.
Depending on the station, definitive data from the report year can usually be released from August of the following year.
The cost of data provision depends on the volume and nature of the ordered data. Special orders, which involve significant research and processing, are billed on the basis of actual costs.
Billing is based on the FOEN's fees ordinance (Gebührenverordnung BAFU) and the federal administration's general fees ordinance (Allgemeinen Gebührenverordnung). Whether the fees can be exempted depends on the purpose of the data: data are provided free of charge to other federal authorities, cantonal authorities and universities.
We assist you in resolving your questions related to hydrological quantities. We advise you in the choice of stations and types of measurement, providing you the relevant data.
