Character & environment

Due to the local geological, geographical and meteorological conditions, the Windach has a pronounced torrential. That is, it swells after rainfall sharply. This behavior resulted in the lower reaches of the river from Finning almost every year to floods, flooding the low-lying meadows and damage to the edges of the too narrow riverbed. To prevent further damage was 1961-1964 south of the Finning Windachspeicher applied in a transverse valley with glacial kettle -shaped extension as flood retention basins. Nevertheless, it was in the lower reaches of Windach in the community Eching 1999 and 2000 again to flooding, which is why there laid in 2008-2009 the riverbed of Windach part and a new flood channel was built.

Origin of the name

Windach is as river name first occupied in 1346 as " the Windah pei ," the town of the same name in 1158 as " Windaha ". The name is derived from the Old High German root word aha " water, river, stream ", and a determination word on a participle form of Old High German Wintan " squirm, turn, twirl ," Middle High German wind ' wind, twist " is expected to decline. The name means therefore probably " spiraling flow," which probably is expressed that the windings of this river change frequently strong.
