geography

course

The Lohgraben rises at an altitude of 449  m above sea level. NN in the area of ​​the city of Weißenburg in Bavaria southwest of Holzingen next to the district road WUG 5 . It first flows in a south to south-east direction and feeds a small pond, after crossing the city limits of Treuchtlingen then a larger pond with a pre-pond. Then it passes the wasteland Naßwiesen on the right bank and bends in front of the hamlet of Grönhart , a little further south, at a small tributary at about 427  m above sea level. NN abruptly on west course. On this slightly longer lower section of the run, it crosses under the district road WUG 5 and a little further on the district road WUG 3 running in the left Altmühlaue . Then it finally takes in the Schertnershofer Graben from the right , its longest tributary, and flows into the wide and flat valley floor of the river from the left and with an obtuse underflow angle at about 410  m above sea level. NN between Lengenfeld and further down Bubenheim in the middle Altmühl.

The 5.2 km long brook flows about 39 meters below its origin and thus has an average bed gradient of about 7.5 ‰; on the approximately 1.9 km long upper course section up to the turnaround it is almost 12 ‰.

Catchment area

The Lohgraben crosses an open landscape north of Treuchtlingen between the 511  m above sea level on the summit . NN height reaching Trommetsheimer Berg on the northwest edge, the highest and only wooded elevation in its approximately 7.9 km² catchment area, which is only up to 467  m above sea level. NN reaching Hungerberg on the northeastern edge and at about 473  m above sea level. NN also noticeably flatter towards the hollow of the Bubenheimer Berg on the southern edge. The catchment area has an almost circular contour; beyond the northeastern watershed, the Wöhrbach competes with the upper Swabian Rezat , which arises behind the following eastern and southeastern waters and is the next noteworthy neighboring water ; on these two sections the catchment area therefore borders on the European main watershed between the Danube on this side and the Rhine on the other side. The south-western border runs close to the route of the Altmühl, only after the Trommetsheimer Berg in the north-west does a larger tributary flow, the Lüßgraben .
