Geography

Stappitzer See, view towards Mallnitz

The lake arose during the last glacial period (Würm glaciation), when the retreat of glaciers led to a Sturzstrom landslide of debris damming up the waters in the Mallnitz valley. After many thousand years of a continuous sedimentation process, Stappitzer See confined by several debris cones is a relict from the ice age.

Plans for a reservoir power station developed by the Österreichische Draukraftwerke AG (present-day Verbund AG) in the 1970s failed due to environmental impacts and local opposition. The lake is a resting area for numerous bird species such as the black-throated loon and the western yellow wagtail, as well as a breeding ground for the little grebe, the Alpine swift, and the Eurasian crag martin. In 1986 it was declared a nature reserve; since 2008 it is a Special Protection Area according to the European Birds Directive.
