Auer Mühlbach
# Auer Mühlbach

Auer Mühlbach is a river in Bavaria, Germany. It is a branch of the Isar in the southern part of Munich.

## History

Long before the "official" founding of the city of Munich, the water power of the Isar was used for the operation of mills. Since the Isar was a wild mountain river and until its increasing regulation from the 19th century on, it frequently changed its course and showed strong level fluctuations. The mill wheels in the Munich area were not built at the unpredictable main branch, but at a regulable, artificially diverted side branch with as constant a water flow as possible, the Mühlbach. The first written mention of the stream and a mill at Kiesingenum (today Untergiesing) is found in a document from the year 957.
