Switzerland's Rhine Falls (Rheinfalls) is the most powerful waterfall in Europe. Located on the High Rhine section of the great river, the Falls are located on the border between the Cantons of Schaffhausen and Zurich. They have a modest drop of 23 meters (about 75 ft.) but a substantial width of 150 meters or just under 500. Average summertime water flow is about 600 cubic meters (around 21k cubic ft.) per second, with record flows of about double that level.
