Grand Canal of Alsace

The Grand Canal of Alsace, whose initial works began in 1928 under the guidance of engineer René Koechlin, is one of the major developments on the Upper Rhine.

Designed to harness the river's hydraulic power while improving its navigability, this artificial canal stretches 52 kilometers from Kembs to Vogelgrun.

It is now lined with four hydroelectric power plants, each equipped with a lock: Kembs, Ottmarsheim, Fessenheim, and Vogelgrun. These facilities both generate electricity from the Rhine's energy and ensure smooth navigation along this section of the river.

A symbol of engineering and sustainable development, the Grand Canal of Alsace has profoundly shaped the landscape of the Upper Rhine.

Nearly a century after its inception, it remains a vital asset to the region, combining energy production and river transport.
