Lungerersee, Lake and reservoir in Obwalden, Switzerland.
Lake Lungern stretches over 2 kilometers in length with varying widths between 200 to 800 meters, reaching depths of 68 meters at its deepest point.
The construction of a drainage tunnel in 1836 reduced the lake level by 36 meters, transforming the water body and surrounding valley landscape permanently.
The Sarner Aa river system connects Lake Lungern to Lake Lucerne, forming an essential water network that shapes the regional identity of central Switzerland.
The lake maintains an elevation of 688 meters above sea level and receives water primarily from the Lauibach and Eibach streams throughout the year.
The underground facility near Lake Lungern contains the only indoor 300-meter shooting range in the world, attracting sports enthusiasts from many countries.
