The Grütz lock is a lock in a puncture along the Lower Havel waterway near the Grütz district of the town of Rathenow .
history
In 1904 it was stipulated by law that in the area of the Lower Havel below the city of Brandenburg the drainage conditions were to be improved so that river meadows that are not diked should have dried up by June 1st of each year at the latest. As a first construction measure, the river cross-section was widened in many places. Furthermore, punctures were made in the area of river bends . Such a breakthrough occurred in the village of Grütz below Rathenow. In order to counteract adverse effects in dry periods due to the accelerated drainage due to the shortening of the flow path , dams were built at Bahnitz , Grütz and Garz . These dams consist of large needle weirs in the middle of the river, which are supposed to maintain the required water level, and small weirs on the edges. These were created with a flow width of 6.40 meters for fine adjustments. The weir systems at Grütz were completed in 1911. Barge locks for smaller watercraft were also built. The Grütz barge lock was built not far from the Grütz lock, but was demolished in the course of the renovation of the weir in 2000–2003.
In order to enable Havel shipping to overcome or bypass the weirs, tow locks were built in the breakthroughs. These each have a length of 215 meters, a chamber width of 23 meters and a gate width of 10 meters. The gradient built up by the weirs and to be overcome by the locks is only slight. The Grütz lock was completed in 1911, i.e. at the same time as the weirs.
