Hochwasserrückhaltebecken Orstel, Flood retention basin in Bolheim, Germany
The Orstel detention basin is a water management facility in Herbrechtingen designed to capture and store water during heavy rainfall events. The structure consists of a curved concrete dam that holds large volumes of water over time, preventing flooding in downstream communities.
The basin was constructed in the 2000s over several years to reduce flooding risk in the region. Its completion marked an important advancement in flood protection for the surrounding communities.
The facility represents German engineering excellence in water management, incorporating concrete and steel construction techniques to protect surrounding communities.
The site is publicly accessible but offers mainly natural spaces without intensive tourist facilities. Visitors should note that this is a functioning structure and the interior of the basin looks different depending on water levels.
The facility includes special passages that allow fish to cross the dam and follow their natural migration routes. This demonstrates how modern flood control systems are designed with consideration for river wildlife.
