Wallstadt Lock and Weir

The expansion of the Main through the construction of barrages took place in several steps upstream. The Wallstadt barrage is in the third construction phase, which was completed between 1926 and 1941.

Locks are always interesting

The Wallstadt barrage is a barrage on the Main at Main kilometer 101.37 between Kleinwallstadt and Großwallstadt. It dams the Main over a length of 11,680 km (Klingenberg lock). The next lock downstream from the Main is almost 8.5 kilometers away in Obernau. The expansion of the Main by building barrages took place in several steps upstream. The Wallstadt barrage is in the third construction phase, which was completed between 1926 and 1941. The barrage includes a weir, a chamber lock, a boat lock, a fish ladder and a power plant. The weir system consists of three cylindrical steel gates, each of which is held at the sides by powerful concrete weir pillars standing in the river. An iron weir walkway for maintenance work runs above the weir. Between the weir and the lock chamber there is a boat lock with a usable width of 2.50 m and a usable length of 12 m.
