Railway service with a fish ladder ramp and turbine house

The Eisenbahnerwehr is an attack weir on the Lech in Augsburg-Hochzoll and Spickel-Herrenbach below the Ara bridge at river kilometers 45.6.

The weir with a width of 108 m forms an approximately 6 m high, stepped slope and lies at 467.8  m above sea level. NHN . The weir was built around 1840 to protect the 400 m above Lech Bridge of the Bavarian Maximiliansbahn .

From 2004 to 2006, a bay power plant was built on the eastern bank on behalf of LUWA Energie GmbH . With two vertical Kaplan turbines with a directly coupled generator, the power plant generates around 2.6 MW of electrical power with a water volume of 55 m³ / s, which means an average annual output of around 12 GWh. A gravel trap with a gravel sluice was installed upstream of the inlet structure to guide the bed load. In addition, a fish pass was built between the weir and the power station as a ramp-like bypass stream with 500 l / s.
