The Reichenbach Falls (German:Reichenbachfall) are a series of waterfalls on the Reichenbach stream in the Bernese Oberland region of Switzerland. They have a total drop of 250 metres (820 ft). At 90 metres (300 ft), the Upper Reichenbach Falls is one of the highest cataracts in the Alps. Today, a hydro-electric power company harnesses the flow of the Reichenbach Falls during certain times of year, reducing its flow.
