25 November 2019, Mecklenburg-Western Pomerania, Rostock: Workers are standing in the drained Mühlendammschleuse. The building inspection will be continued at the Mühlendammschleuse, which has been out of operation since 2011. After completion of the inspection, a sheet pile wall and a dam body will be built in the lock to secure the site for flood protection and drinking water supply from the Warnow. The city can then decide how to proceed with the lock, which is then no longer in the care of the Federal Waterways and Shipping Administration. Photo: Bernd Wüstneck/dpa-Zentralbild/dpa
