Biberdämme

Biberdämme are small, earthen dams typically found in Upper Austria and Bavaria in southern Germany. They are used to regulate the flow of water in streams and rivers, especially during the winter months when snowmelt from the surrounding mountains causes water levels to rise.

Biberdämme are usually built from natural materials such as stones, branches, and soil. They may also be reinforced with wooden planks or metal mesh. The size of the dams varies, with some being as small as five meters in length, while others can reach lengths of up to 100 meters.

The purpose of Biberdämme is to prevent flooding, maintain water levels, and regulate the water supply for local irrigation and drinking water needs. They can also help to promote the growth of aquatic plants and support local fish populations. By controlling the water flow, Biberdämme also reduce the risk of ice formation and erosion of the stream banks.

The name "Biberdamm" or "Biberdämme" refers to the rabbits (biber in German) that are known to use these small dams as a crossing point, especially during the winter. This has led to the local name "Biberdämme" being associated with rabbit conservation and local wildlife.

Biberdämme are maintained and monitored by local authorities, often in cooperation with environmental organizations and local communities. As part of efforts to protect and restore these small dams, conservation initiatives have been established to promote their repair and restoration.
