Swiss lakes at lowest-ever August levels

GENEVA: Some of Switzerland’s best-known lakes are at their lowest level ever for August after a dry year so far in 2022, the environment ministry said on Wednesday.

At the same time, discharge levels on the Rhine, one of Europe’s major rivers which starts in the Swiss Alps, have never been so low in August since records began. "There is a low water situation in Switzerland, especially on the central plateau and in the southern part of Ticino," the country’s southernmost canton, said Michele Oberhansli, from the Federal Office for the Environment’s hydrology division.

"The reason for the existing situation is a precipitation deficit in the whole year of 2022, which affects the whole of Switzerland, as well as many other European countries," she told AFP. Soil moisture is down across the country and drought is affecting forests and agriculture, she said.

Lakes Constance, Lucerne, Lugano and Walen "are currently recording water levels that have never been so low in an August month since measurements began", said Oberhansli. Meanwhile Lakes Zug and Maggiore "continue to show values well below average".

The shores of Lake Maggiore mark the lowest point in Switzerland, normally at 193 metres above sea level. Except the lakes in the Jura region in the northwest and Lake Thun, the levels of all the other larger Swiss lakes are also below the long-term average.

Meanwhile many Swiss rivers are recording readings that only occur once every two to 20 years. "Discharge values on the Reuss and Rhine have never been so low since measurements began in August," said Oberhansli.
