Püttlach

The Püttlach is a left tributary of the River Wiesent. It is about 27 km long and flows through the Bavarian region of Franconian Switzerland in Germany.

Course
The Püttlach rises in Franconian Switzerland, south of Bärnreuth at a height of about within the parish of Lindenhardter Forst-Nordwest, near the source of the Red Main and origin of the Fichtenohe, a headstream source of the Pegnitz river. It initially flows northwest to the Pond (Püttlachweiher). There it turns sharply to the south and flows through woods. In Muthmannsreuth, it is fed from the left by the Heringsbach and, at Heringslohe, from the right by the Heroldsgraben. West of Trockau is the Herrenmühle and, in the vicinity, a sewage treatment plant. Just south of a second mill, the Heddelmühle, it is joined from the right by the Kohlbrunnbach. Near the Hasenloch it is fed from the right by the Pullendorfer Bächlein brook. It flows through the eponymous parish of Püttlach in the borough of Pottenstein. To the south of the town it makes its way through fields and meadows to an area with many small ponds. There it is boosted from the left by the Grießbach stream. It continues to flow south through a deep valley to the Hollenberg Forest. Blocked by a hill range, it turns 90 degrees to the west before cutting through the ridge and passes through the upper Püttlach valley, past the Adamsfels Cave as far as Pottenstein. In the town, the Weiherbach joins the Püttlach from the left. Nearby is another mill and, on the western edge of the town, the hammer mill. The Püttlach now flows westwards through a narrow gorge and empties into the Wiesent at Behringersmühle where the Ailsbach (or Aßbach) joins from the right (mouth height approximately ).
