01.07.2019 - The Hydrological Yearbook gives an overview of the hydrological situation in Switzerland. It shows the changes in water levels and discharge rates of lakes, rivers and ground- water and provides information on water temperatures and the physical and chemical properties of the principal rivers in Switzerland.
06.06.2019 - 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.
05.06.2018 – Dive into the FOEN’s new video and experience Switzerland’s water bodies like you’ve never seen them before. Take a seat next to pilot Nino G from planet Nuxxo and accompany him on an adventure through Switzerland’s riverine landscapes.
There is a wide diversity, ranging from real-time water temperature in rivers, through groundwater protection zones to the potential for small hydropower plants. Subject-related data such as the water storage capacity of the ground or the distribution of rock strata are also included. “Topic Water” at map.geo.admin.ch.
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.
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.
