Data, indicators and maps

The FOEN collects and publishes a lot of data and derived products on the topic of water. These pages contain links and overviews of the available sets of measurements and geodatasets as well as information on how to obtain current and historical data. Detailed information on individual datasets can also be found on the corresponding topic pages.

Indicators

Assessing and illustrating the status and trends of the environment with a selection of key sizes.

Water monitoring data

Links to current monitoring data on water bodies and possibilities of obtaining data.

Overview of water geodata

The FOEN publishes many maps and geodata sets on the topic of water. Many of them can be viewed on the Federal map portal. They can also downloaded as geodata sets for personal use.

Geodata models

Geodata models for the FOEN’s official geodata on the topic of Water

Waterbody catchment areas

Catchment size, the elevation of the region, gradient or land cover: the catchments and their regional characteristics are often of additional importance in an analysis of Swiss hydrological monitoring data. The catchments of Swiss waterbodies and the catchments of the FOEN hydrometric gauging stations and the major features of the regions are available as a geodataset.

Hydrographic network

The Swiss hydrographic network comprises all surface and subsurface rivers, streams and canals. Lakes are also included. Both natural and artificial water bodies are considered. The water bodies and their hydrological catchments serve as spatial references for literally any question, problem and project related to hydrology and water resources management.

Hydrological Atlas of Switzerland HADES

The Hydrological Atlas of Switzerland HADES is a collaborative work by Swiss hydrological agencies (federal offices, cantons, research institutions and private specialist offices in the water sector). For more than 30 years, it has made basic hydrological information, specialised knowledge and didactic media available to a wide range of users. The Atlas comprises the original map series of 63 printed plates, and a wide range of more recent products. These are accessible via hydrologischeratlas.ch.

Overview of monitoring networks

The FOEN operates and coordinates several monitoring networks on the topic of water. Long-term measurements at permanent gauging stations and individual readings at temporary sites enable the FOEN to keep track of water flow and quality in Switzerland’s rivers and groundwater, as well as the water level in its lakes.
