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.
The station lists provide you information on the status, measuring period, and measurement parameters of individual stations.
Recency and quality of data
Measurement rows from operating stations are recorded up to the current year. However, verified but provisional digital data can usually be delivered after about one month. These data can also be retrieved in table form (pdf) via the Internet after about one month. 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.
In general data are provided free of charge.
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).
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.
