The character of the river has been changed over long distances by the construction of hydropower station. The Laufenburg and Schwörstadt Rapids were removed by blowing up rocks, originally to improve navigation, and later flooded due to the hydropower dams.
Between Diessenhofen and Stein am Rhein, the High Rhine has yet to be dammed. The first power plant of the Rhine river is currently at Schaffhausen; it has a damming effect to slightly above Diessenhofen. The next power plant (the Kraftwerk Reckingen) is located at Rekingen and Küssaberg. After Rekingen, the High Rhine flows freely through the Koblenz Rapids to the confluence with the Aar.
