Construction edit
The barrier is a crooked gravity dam made of concrete with rubble stone cladding. It was renovated in 2000 and was the first dam in Germany to be sealed with a plastic sealing sheet (geomembrane) of PVC on the reservoir side. In 1955 it had already been reinforced with concrete on the reservoir side.
Power edit
The power capacity of the hydropower station is 300 kW; it generates 0.7 GWh per year. It is operated by the town of Bräunlingen.

Since 2008, the Kirnbergsee has been assessed as of "excellent quality" according to EU bathing water standards.[1]
