Staustufe Schlüsselburg, Staustufe in der Weser in Petershagen, Nordrhein-Westfalen, Deutschland
The Staustufe Schlüsselburg is a hydroelectric installation on the Weser River featuring a weir with two fields of 40 meters each and an adjacent power station. The facility controls the water level and uses the river's fall to generate electricity through its turbine system.
The barrage was built in the 1950s and completed in 1956 to regulate water levels and generate electricity. The facility changed operators multiple times, beginning with PreußenElektra, then becoming part of EON, before Statkraft took ownership in 2009.
The barrage has become a familiar landmark in the local landscape where the Weser flows through Petershagen. For residents and visitors, the structure represents how the community harnesses water for practical purposes while maintaining the river's presence in daily life.
The site is accessible to pedestrians and cyclists with flat, paved paths around the installation. It makes for a pleasant walk along the riverbank where you can observe boat traffic and the flow of water through the structure.
The installation is one of six control structures along the middle Weser that work together to manage the river's water system. This networked infrastructure demonstrates how multi-stage river regulation keeps the waterway stable.
