The Tamed Rhine – Switzerland, Germany, France is a 2011 German documentary that explores the journey of the Rhine River from its origins near Schaffhausen, Switzerland, where the Rhine Falls—492 feet wide and 82 feet high—formed approximately 15,000 years ago during the last ice age. The film follows the river as it passes 20 hydroelectric power stations, the city of Basel, and a conservation area in the Petite Camargue, where efforts to breed and reintroduce salmon are underway, before reaching the city of Strasbourg.
