The Kirnach ( Bavaria ) is an approx. 30 km long river in the Ostallgäu district . It flows through the communities of Unterthingau , Aitrang , Ruderatshofen and Biessenhofen . It rises west of Görisried in the Kempter Forest and flows northeast of the Biessenhofen district of Ebenhofen into the Wertach .
Due to regular flooding on the lower reaches of Ebenhofen and Biessenhofen, extensive flood protection measures with guide dikes, protective walls and road elevations were carried out in 2005/2006 in the mouth area at the Kirnach power plant. A flood area was created above the Kirnach power plant, which is led past the power plant via a base ramp into the underwater area of the power plant. In the mother bed of the Kirnach 30 m³ / s remain, in the flood area 50 m³ / s flow over a wide area.
Kirnach power station
The small power station Kirnach ( 47 ° 49 '17.9 ″ N , 010 ° 37 ′ 48.6 ″ E ) is a run-of-river power station at the confluence of the Kirnach into the Wertach . The power plant operated by Vereinigte Wertach-Elektrizitätswerke has a bottleneck output of 152 kW at a flow rate of 2.1 m³ / s and is driven by a Kaplan bulb turbine. The usable fall height is 7.05 m. The dam is equipped with an automatic dam with a width of 1.50 m and a height of 1.55 m and is intended for a discharge capacity of approx. 5 m³ / s.
Weir and turbine come from the Austrian manufacturer Kössler. The power plant was rebuilt in 1999, in 2005/2006 extensive flood protection measures were carried out above the power plant with dikes, protective walls and road elevations.
