Swiss Water Bodies in a Changing Climate

16.03.2021 - There will be no general shortage, but water may be scarce depending on the region and time of year – conversely, heavier rainfall will lead to more local flooding. These and many more are the findings of the Hydro-CH2018 “Hydrological Principles of Climate Change”.

EEA report on bathing water quality 2019

08.06.2020 - Thanks to various protective measures and major advances in wastewater treatment in recent decades, water quality in Swiss rivers and lakes is now very high and virtually all are clean enough to swim in.

'Rhine 2040' programme adopted

13.02.2020 - The 16th Conference of Rhine Ministers was held in Amsterdam on 13 February 2020. It successfully adopted the 'Rhine 2040' programme, with its new and ambitious targets for biodiversity (the return of migratory fish), water quality (a reduction in micropollutants), climate change, flood defences and measures to deal with low water levels.

Water flow and flow regime

Water supply depends on natural factors and is influenced by hydropower production and climate change. The FOEN is monitoring the water flow and flow regime of Swiss bodies of water. 

Monitoring data and statistics

Current monitoring data on bodies of water, the possibility of obtaining data, information about extreme value statistics and data on the water withdrawn and returned

State of waterbodies

Despite the generally good quality of its water, residues from fertilizer and plant protection products, chemical residues from wastewater, as well as man-made structures and artificial obstacles damage surface and underground waters.

Ground water

Good quality groundwater is available in sufficient quantities almost everywhere in Switzerland. Traces of artificial, rather persistent substances are found mainly below cropland and in settlement areas.
