The Kander is a river in

The source of the Kander is fed from the

Below Frutigen the river flows through Reichenbach im Kandertal, where it meets the Chiene, and Mülenen, where it meets the Suld. Finally, near the village of Wimmis, it meets the Simme. The valley downstream of Frutigen is known as the Frutigtal.[2]
The last short section of today's river, the Kanderschlucht or Kander canyon, is artificial, having been created as a result of the Kander Correction (see below). At the end of the canyon, the river flows into Lake Thun.[2]
Between Mülenen and Kandersteg, the river is followed by the
Kander Correction
The Kander originally flowed through the low lying Thun Allmend area and entered the
As the river flowed within a few hundred meters of Lake Thun, there were early proposals to divert the river into the lake, thus avoiding the Allmend and stopping the flooding. At the beginning of the 18th Century, the engineer Samuel Bodmer created plans involving a cutting through the Strättlighügel ridge that separated the river and lake.[3]
The plans were approved in 1711, and work began but was delayed by the second Battle of Villmergen. In the spring of 1713 work restarted under the direction of Bern's city architect Samuel Jenner, but with a tunnel instead of the unfinished cutting. Work was finished by the end of the year, but in 1714, the river started to enlarge the channel, causing the tunnel to collapse and creating today's Kanderschlucht or Kander canyon.[3]
The Kander correction was the first piece of major water course re-engineering in Switzerland and lack of experience subsequently led to problems. The amount of water flowing into Lake Thun was increased by 60%, with a commensurate increase in outflow through the city of Thun. This caused flooding and bank correction, which has been addressed over the years in different ways, including channeling of the Aare in 1716, a more major correction of the Aare in the 1870s, and a flood relief tunnel in the early 21st century.[3]
