Hydrological Data Service for watercourses and lakes

Historical data from hydrometric stations on Swiss watercourses and lakes can be ordered from the Hydrological Data Service.

Records, some of which go back to the 19th century, are available both on paper and in digital format. Data can be obtained on water levels, discharge, sediment transport, temperatures and various physical and chemical water properties.

Station lists

The station lists provide you information on the status, measuring period, and measurement parameters of individual stations.

Data currency and quality

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 in 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 federal authorities, cantonal authorities and universities.
