geography

Friesenquelle

The Friesenquelle near Kasendorf

The Friesenquelle ( 410  m above sea level ) is located southwest of Kasendorf . It is a typical karst spring ; With a very constant average discharge of 400 liters per second, it is one of the strongest springs in Upper Franconia . It does not dry up even in dry seasons. After the snow has melted or after heavy precipitation , the bed of the bed of the strata increases significantly. The spring water then has a deep brown color and comes from a very large catchment area that extends over the surrounding towns of Reuth, Azendorf and Welschenkahl. It emerges from caves and underground lakes . The Friesenquelle has been designated as a natural monument and by the Bavarian State Office for the Environment as geotope 477Q002. See also the list of geotopes in the district of Kulmbach .

course

Shortly after its source, the Friesenbach operates the Friesenmühle. At the powder mill in Döllnitz it takes its largest tributary, the Aubach flowing down from Thurnau . Across from Threschen it flows into the Red Main .
