The Keltersbaumbach is a left tributary of the Godesberger Bach in Bonn and runs in the Schweinheim district in the Bad Godesberg district . Its total length is 1090 meters, its catchment area is 1.1 square kilometers.

Naming

The name Keltersbaum goes back to historical viticulture on the north-east exposed valley slope.

course

The Keltersbaumbach rises about 500 m east of the Hermann Löns monument on the southern slope of the Kottenforst plateau between Venner Straße and Marienforster Kirchweg. The stream does not have a point source, but is formed in its headwaters from several small watercourses, which are fed by layer springs that emerge from the main terrace as an aquifer.

Initially, the stream runs in a wooded area in an easterly direction, until it bends to the southeast after approx. 450 m below the agricultural area of ​​the Marienforst estate . Here he takes on some side runs. In its further course, the stream flows until it crosses under the Im Hohn road within a notched valley with sometimes high erosion rates and a pronounced SW-NE valley asymmetry. From the road underpass, it is then piped for 60 m and then crosses some private gardens, although here there is little proximity to nature. After the Keltersbaumbach has reached the state road 158, it runs parallel to it for about 180 m in a south-westerly direction in a ditch until it passes under it at Gut Marienforst and after a further 70 m in a north-east direction it flows into a still water. The overflow of this pond, which has already been partially silted up by sediment loads, then drains into the Godesberger Bach .

The stream flows through the forest area, settlement area and agricultural land. The water quality in the non-piped areas is II.

particularities

The special geological situation on the edge of the Kottenforst Plateau causes the extensive discharge of groundwater in the source area.

The beginning of the formation of sources can be dated to around 10,000 years ago ( Quaternary , Holocene ).

The water ecology in the forestry upper reaches is almost undisturbed.
