The Kander is a river in

city of Thun, since 1714 it flows into Lake Thun
upstream of the city.

The drainage water from the

Engstligental with Adelboden at its south end, runs more or less parallel to the Kandertal before they converge into the Frutigtal. Continuing northwards, the Frutigtal makes a long bend to the west in order to get around the Niesen. Between Spiez and Reutigen it converges with the Simme from the left, its major tributary, and turns to the north again and flows into the Lake of Thun after a break through a hill, which used to prevent it flowing into the lake until 1714. Here the river crosses the A6 motorway
.

Course

The source of the Kander is fed from the

Kanderfirn glacier in the Blüemlisalp massif. Initially the river in an easterly direction, until it turns sharply north just south of the village of Kandersteg. This section of the valley is known as the Gastertal.[1]

In Kandersteg, the

Oeschinensee, joins the Kander. The river then runs north through Kandergrund as far as Frutigen, where it is joined by another tributary, the Engstlige.[2]

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

Rhone Valley. A road also follows the valley to Kandersteg and beyond into the Gastertal, but unlike the railway this is a dead-end, with no through road route across the mountains.[1][2]

Kander Correction

The artificially created Kanderschlucht

The Kander originally flowed through the low lying Thun Allmend area and entered the

city of Thun and Uttigen. As a result, the Allmend was repeatedly flooded.[3]

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]

Navigation

The Kander at Klus, upstream of Kandersteg

With respect to

Swiss Army rafting party's inflatable boats capsized during an attempt to navigate the river; five soldiers were killed.[4]
