The Ofenwald Dam near Sonthofen in the Oberallgäu district in Bavaria is a flood retention basin without permanent congestion.
description
The barrier structure is the only real arch dam in Germany; only the Okertalsperre can still be called an arch dam to a limited extent.
The concrete dome wall is 22 m high above the valley floor. It was built from 1960 to 1961 (the trial damming began in 1961) and dams the Winkler Starzlach during floods with a discharge of more than 8 m³ / s. The design flood is 92 m³ / s and the overflow height is 922.00 m + NN.
The total storage space is 300,000 m³ and the normal storage space is 210,000 m³. This makes the basin the smallest water reservoir that belongs to the Free State of Bavaria . It has a pre-lock , the ore mine lock with 200,000 m³ of storage space with permanent backlog.
