The Myra Falls are located in a ravine in the municipality of Muggendorf in the Austrian federal state of Lower Austria. The ravine has been cut by the Myrabach, a small tributary of the Piesting.
The Myra, as the stream is also known, rises at the foot of the Unterberg from the Myralucke, a spring steeped in legend, that is fed by an underground lake. Although the Myra is only a few kilometres long, it used to power a large number of mills and sawmills in the Myra valley.
In 1899 plans were laid for "the exploitation of this waterfall for industrial purposes and thus the destruction of a natural beauty".In 1912 Lord Oskar of Rosthorn built a small pumped-storage power station at the Myra Falls, that was in operation until 1974/1975.
