Interlaken ship canal

Geschichte

The Interlaken ship canal is a 2.75km long canal in the Swiss canton of Bern. It connects Lake Thun with a quay in the town of Interlaken adjacent to Interlaken West railway station, thus allowing shipping services on the lake to serve the town and connect with railway services. It is still in regular use by the Lake Thun passenger ships of the BLS AG.The canal parallels the Aar river throughout its length. It has no locks and maintains the same water level as Lake Thun throughout. As a consequence, the water level of the canal at Interlaken West is significantly lower than that of the adjacent river and surrounding land.At the other side of Interlaken, the uppermost reach of the Interlaken section of the Aar river is used by the Lake Brienz passenger ships of the BLS AG to reach Interlaken Ost railway station. However there is no navigable connection between the two lakes, and in the 5.5km between them the Aar river drops some, passing over several weirs.HistoryShipping services on Lake Thun date back to at least 1834, when the first steamship was introduced to connect the towns of Thun and Interlaken, at each end of the lake. Interlaken is actually situated on an unnavigable section of the Aar river between Lake Brienz and Lake Thun, and initially services docked at Neuhaus, some 3km away.
