Rieslochfälle, Waterfall in Bodenmais, Germany.

Rieslochfälle is a waterfall in the Riesloch gorge about two kilometres northeast of Bodenmais, where the Schwellbach, Kleinhüttenbach and Wildauerbach streams join to form the Riesbach. The falls drop over five mainly sliding steps with a total height of 55 metres, the main fall being 15 metres high. The gorge, cut into gneiss between 780 and 920 metres above sea level, is 1.6 kilometres long.

The gorge was cut by backward erosion into gneiss between 780 and 920 metres above sea level along a 1.6 km stretch. Since 1908 water has been diverted in the upper part to generate electricity, reducing the volume reaching the falls. On 28 March 1939 a 32.9-hectare area was designated the Riesloch nature reserve, and the state forestry administration added a 48.5-hectare natural forest reserve of the same name.

The gorge's name, Riesloch, refers to the ravine where the Schwellbach, Kleinhüttenbach and Wildauerbach streams merge into the Riesbach. Since 1908 water has been diverted in the upper section to generate electricity, so the falls carry less water than before. The gorge holds old mountain mixed and spruce forest with glacial relic plants such as Salix appendiculata.

The hiking paths to the waterfall are clearly marked from Bodenmais and lead to viewing areas with good sightlines of the water. The best time to visit is during warmer months when the trails are dry and easy to walk.

The gorge was carved by backward erosion into gneiss, and the rocks beneath the falls are partly covered entirely in moss. Scattered potholes, formed by swirling water, can be seen in the rock. Since 1908 water has been diverted in the upper section for hydroelectric power, so the falls carry less water than before.
