Staustufe Zeltingen, Water barrage on the Moselle River in Zeltingen-Rachtig, Germany.

Staustufe Zeltingen is a barrage on the Moselle at kilometre 123.84, between Zeltingen-Rachtig and Wehlen, with two parallel ship locks (170 by 12 metres and 210 by 12.50 metres) and a boat lock of 18 by 3.3 metres. It holds the river at 106.5 metres above sea level and has a drop of 6 metres.

Built in 1964, this locking system was the first on the Moselle to feature two parallel main chambers working together. It significantly improved shipping capacity and shaped river infrastructure for decades.

The lock lies at Moselle-km 123.84 between Zeltingen-Rachtig and Wehlen, in the Middle Moselle wine area. Its 6-metre drop and 17.64 km holding stretch sit among vineyard slopes; the lock is named after Zeltingen, the wine village on the right bank.

Visitors can watch the locks in operation from publicly accessible areas, particularly from the riverbanks and viewing platforms. The best time to see activity is during the shipping season when boats regularly pass through.

The run-of-the-river power plant at the barrage, built in 1964, has a capacity of 13.6 megawatts and is operated by RWE Generation Hydro. It uses the 6-metre head between the 106.5-metre headwater level and the lower reach. The plant sits beside the locks at Moselle-km 123.84.
