Staustufe Müden, Hydraulic barrage in Müden, Germany.

Staustufe Müden is a barrage on the Moselle at kilometre 37.11, between Müden and Treis-Karden in Rhineland-Palatinate. It comprises a 170 by 12 metre ship lock, an 18 by 3.2 metre boat lock and the Müden run-of-river power station of 1965, which supplies 16.4 megawatts and is run by RWE Generation Hydro. The drop height is 6.5 metres and the impounded reach is 22.27 kilometres long.

This structure was completed in 1964 as part of a major effort to improve the Moselle River for commercial freight traffic. The power plant was added shortly after, transforming the river into an energy source while maintaining its role as a shipping route.

The lock shapes how people travel and trade along this river valley, connecting the wine regions upstream and downstream. Visitors can observe commercial barges and pleasure boats passing through daily, showing how river commerce remains central to life here.

The lock lies at Moselle-km 37.11 between Müden and Treis-Karden, with the boat lock measuring 18 × 3.2 m for smaller craft. A normal passage takes 20 to 30 minutes, so allow time to watch a complete locking cycle. The site is administered by the Wasserstraßen- und Schifffahrtsamt Mosel-Saar-Lahn.

On 8 December 2024 a cargo vessel badly damaged the lower lock gate, trapping 74 ships on the Moselle. The damaged gate was removed on 13 December and replaced by nine steel beams normally kept for maintenance closures, lowered by crane; the first ship passed on 16 December, and normal operation resumed on 1 February 2025.
