Staustufe Trier, Hydraulic barrage on Moselle River in Trier, Germany.

Staustufe Trier is a water regulation structure on the Moselle with locks for boat traffic and hydroelectric generation capacity. The installation includes multiple components working together to manage river flow and produce energy.

The structure was built in the 1960s and represents a turning point in how the region manages its waterways. Its completion enabled more modern approaches to river use and power generation.

The lock's first control centre on the Moselle opened in 2021, alongside the second lock chamber, so operations are now run from Trier. The chambers carry the names of the districts they touch: the barrage lies in Trier-Euren, the adjoining Moselkraftwerk in Sankt Matthias. The fish ladder lets visitors see upstream migration past a 7.25 m drop.

The lock chambers allow boats to navigate past the height difference and travel upstream or downstream without disruption. Visitors can watch the system operate from the riverbank and explore the infrastructure from outside.

The Moselkraftwerk Trier, the run-of-river plant attached to the barrage, dates from 1961 and produces 18.8 megawatts, operated by RWE Generation Hydro. The barrage itself went into service in 1964. In 2021 the first control centre on the Moselle and the second lock chamber opened here.
