The Pfengstbach is a 3.87 km long orographic left tributary of the Dhünn , a tributary of the Wupper .

geography

course

Its source is located northeast of the Nothauser Feld in the Scheuren district of the Odenthal community at an altitude of 209  m above sea level. NHN .

The stream initially flows almost northwards through the forest, then turns west and then enters the nature reserve of the same name . It now changes its direction to the northwest and meanders slightly through the wooded valley.

After the inflow of the Schmeisigbach, it then runs westwards and finally flows south of Altenberg at an altitude of 87.7  m above sea level. NHN from the left into the Dhünn.

Catchment area

The approximately three and a half square kilometers large catchment area of ​​the Pfengstbach lies in the Bechen plateau and is drained to the North Sea via the Dhünn, the Wupper and the Rhine .

It will

  • in the north by the pain Berger Siefen , the Springsiefen and the Hasselssiefen
  • in the northeast by the Bömericher Bach
  • in the east by the Buschbach
  • in the southeast by the Berger Siefen and the Meuter Bach
  • in the south by the Hortenbach

limited.

The catchment area is largely forested in the center and west, and settlement areas and agricultural zones predominate in the east. The area is characterized by clay , silt , sand and limestone of the Middle Devon .

Historical and current use

A Romanesque basilica was built in 1145 by the Altenberg Abbey as a predecessor to today's Altenberg Cathedral on the three to five meter-thick alluvial fan in the original mouth of the Pfengstbach . In order to create a dry subsoil for this purpose, the Pfengstbach was diverted at its valley exit with the help of an arched dam to the eastern edge of the Dhünntal to today's confluence south of Altenberg. In order to supply Altenberg Abbey, at least six ponds were created for fish farming after 1133, which were supplied with the necessary fresh water by the Pfengstbach. The Spezarder Mühle , located in the Pfengstbachtal, was a grain mill, which, however, did not get its water power directly from the Pfengstbach, but was supplied by the Backesberger Bach , which was dammed up to a mill pond and was led via an upper ditch to the Spezarder Mühle. Until a central water supply was established in the municipality of Odenthal at the beginning of the 1970s, numerous farms and localities gained drinking water from the sources of the Pfengstbach and its tributaries, as evidenced by several dilapidated wells .

Even today, the Pfengstbach supplies the fish ponds located on its lower course with fresh water. The Pfengstbachtal is a near-natural meadow valley with its wet and wet meadows and the side depths, a biotope for many animal and plant species and has therefore been designated as a nature reserve in large parts since 1994. In addition, it serves those seeking relaxation with its hiking trails as a local recreation area and houses a culture and forest nature trail.
