(sda) The level of Lake Thun exceeded the flood limit of 558.3 meters above sea level on Wednesday night, as predicted. The regional management body assessed the situation as “not dramatic”.
That said the head of this body, Heinz Wegmüller, in the morning in the regional journal Bern Freiburg Wallis from Radio SRF. Wegmüller said the fire brigade had to pump out individual cellars. And in the suburbs of Thun the lake has occasionally overflowed its banks.
The level of the Aare in Thun is still well below the damage limit. At the weekend in downtown Thun, the fire brigade set up mobile flood protection barriers at critical points. The city of Bern also took precautions.
After a blockage due to the risk of debris flows, the Grimsel and Susten passes as well as the Nufenen reopened on Wednesday morning. In contrast, the BLS interrupted the Bern S-Bahn lines 4 and 44 between Burgistein and Uetendorf due to the risk of landslides. She used replacement buses.
The risk of flooding increased in Lucerne and the canton of Zug. The level of Lake Lucerne has risen by around 20 centimeters since Tuesday evening. On Wednesday at 7.30 a.m. it was 434.70 meters above sea level and thus about one meter above normal level. The highest of five danger levels has been in effect for Lake Lucerne since Tuesday evening.
The fire brigade had strengthened the protective measures on the banks of the Reuss on Tuesday evening. Some of the sidewalks and bridges on the Reuss were closed on Wednesday morning.
The abundance of water in the Reuss is also causing problems in the canton of Zug. The municipality of Hünenberg is particularly affected, said the cantonal management staff. The Reuss dam could break with the current water situation. There is currently no danger for the youth camps in the canton of Zug.
The Zentralbahn closed its route between Hergiswil NW and Sarnen OW after the Sarner Aa had washed over the slab of a railway bridge. The train does not run between Dallenwil NW and Engelberg OW due to storm damage on Saturday.
In Uri, the situation on the Reuss calmed down. In the Urserental, where rail traffic between Andermatt and Realp was suspended on Tuesday, the trains were running again.
Landslides occurred in a number of communities. A road slipped in the Klöntal in Glarus. It can only be driven on with lighter vehicles. In Oberägeri ZG, residents of a threatened property were evacuated after a landslide. In the canton of Vaud, a slide between Cully and Rivaz fell on the road on Lake Geneva. The cleanup could take several days.
The Zurich waters were all just below alert level 4 on Wednesday morning, i.e. a few centimeters below the high water mark. However, the canton expects that this mark will be exceeded in the next few days.
Already on Tuesday evening, the building management announced that the Lake Zurich level would probably reach danger level 4 (high) due to the persistent rain.
The water level of the Limmat is also likely to rise further due to the high level of Lake Zurich. As a precautionary measure, the level of the Sihlsee dam was already lowered on Tuesday evening so as not to pollute the Limmat additionally. Boating and swimming in this river and also in the Sihl are prohibited. In general, people should stay away from the shores.
In the canton of Aargau, the water levels of the Rhine, Aare, Reuss and Limmat fell slightly below the highs of the past 24 hours. The risk of flooding remained increased.
At SBB, the railway line to the Zurich Furttal between Zurich-Seebach and Regensdorf-Watt was interrupted on Wednesday morning.
