The Wolterdingen flood retention basin was built between 2006 and 2012 on the outskirts of Donaueschingen- Wolterdingen in the Black Forest-Baar district , Baden-Württemberg .
construction
The flood retention basin is intended to improve flood protection on the Breg and Danube. It will significantly reduce the flood peaks of the 100-year flood. It is a dry basin that is only filled when there is high water. The possible storage capacity of the basin is 4.7 million m³. The storage area will then be 70 hectares. The building owner is the state of Baden-Württemberg.
The dam is slightly curved and has a height of 18 m above the river bed. The dam will be built continuously for fish. At normal water levels, these should be able to swim through one of three passages, the so-called eco - tunnels .
history
The groundbreaking ceremony took place on July 13, 2006 . The reinforced concrete work will be carried out from 2006 to 2008, and the hydraulic steelworks from 2006 to 2011 . The dam was dumped from 2008 to 2011. On June 29, 2012, the flood retention basin was put into operation as part of a ceremony. The construction costs are given at 23 million euros.
A trial jam was carried out before Christmas 2012. During this trial jam, a section of the L180 road was flooded, but it survived this process undamaged.
