The weir connects the northern part of the English Garden with Oberföhring. Here, the middle-Isar-channel is discharged and then flows at Moosburg back into the river. The Oberföhringer weir was renovated in 2008 and generates 5.7 million kilowatt hours of electricity per year. Since then, the Isarfish can overcome the weir over a fish ladder.

The dam Oberföhring is a weir on the Isar in the north of Munich and at the same time the inlet structure of the Mittler Isar Canal.
However, the weir itself is not a hydroelectric power station. But there is immediately below the weir a small, largely subterranean power plant, over the water from the channel is returned to the Isar.
The old salt road must have gone here in the vicinity over the Isar.
From 1896 until the construction of the weir was operated at this point a cable ferry. Mittlerer Isar GmbH began in 1918 with the planning of the canal. In 1919, the planning became the property of the Bavarian state, which began construction work to combat unemployment. Mittlere Isar AG, founded in 1921, then took over the project and completed the dam in Oberföhring until 1924. During this time, the four concrete arch bridges were built, which connect Oberföhring with the headland formed by the channel called Isarinsel.
The weir and these bridges survived the Second World War, as the demolition of the bridges before the invasion of the Americans was prevented throughout Munich. The bridge near St. Emmeram was replaced in 2003 by a modern reinforced concrete structure.
In 2002, between the Free State of Bavaria and E.ON Wasserkraft, an increase in the amount of residual water remaining in the river Isar to the current level of 15 m³ / s was agreed, as well as its use by a new power plant to be built on the weir; At the same time, the ecological conditions on the Isar between Oberföhring and Moosburg should be improved. In the following years the weir was renovated. The power plant went online in 2008; It generates 5.7 million kilowatt hours of electricity per year and the power plants on the Mittlerer Isar Canal a total of about 430 million kilowatt hours. In addition to the power plant is a new fish ladder created since 2012.
