The Jettenbach dam is a weir in the Inn in the Fraham district of the municipality of Aschau am Inn . It was named after the town of Jettenbach, one kilometer to the south, in the municipality of the same name.

The system was built between 1919 and 1923 to divert headwater from the Inn to the Töging power plant via the Innwerk Canal . For this purpose, the Inn is dammed over a length of 8 km and most of the water is drained into the canal. The weir was built by the Innwerk, Bayerische Aluminum AG , in order to supply an aluminum smelter in Töging with electricity with the Töging power plant. Innwerke's successor, E.ON Wasserkraft , sold the power station, the canal and the associated dam in 2009 to the Austrian company Verbund AG .

The weir system has 6 openings, each 17 m wide. The drives of the shooters are located in a wood-clad superstructure above the weir. The inlet of the Inn Canal is almost at right angles to it. Both parts of the facility are under monument protection.

Hydropower plants

Two power plants were also built at the dam. They give off a certain amount of residual water into the Inn.

In 1924 a power plant with a single Francis turbine and an output of 0.4 MW was built on the east side of the weir . The flow rate is 5 m³ / s.

In 2004 another power plant with two Kaplan turbines and a total output of 5 MW was built on the west side . The flow rate is 35 to 50 m³ / s.
