Hachinger Bach

Hachinger Bach at Unterbiberg

The Hachinger creek flows south through the towns of Munich Oberhaching, Taufkirchen, Unterhaching and Unterbiberg and enters Perlachturm in the city of Munich. He twelve kilometers long.

The Hachinger Bach created in a former glacial trough between the districts and Deisenhofen Oberhaching where the light coming from Deininger Weiher Gleißental that leads only groundwater, but no surface water is to Hachinger valley. At a length of about 100 m, the soil is always moist ground water by leaking until a small stream has formed. Since the groundwater level fluctuates greatly, there is no clear source. Thus, the stream can not fall completely dry, a water pipe is introduced into the stream beside a park path. Further groundwater access and tributaries such as the Entenbach at Taufkirchen let the water flow increase somewhat. The waterproofing Flinzschicht, which provides for the emergence of the creek, north of Unterhaching decreases sharply, and thus the groundwater. Therefore, the stream would have been there seep into the gravel of the Munich gravel plain. Since he has, however, created by his own mud deposits a reasonably dense bed, he's previously only north of the present Ost Park, seeps at the border of the districts of Perlachturm, Ramer village and Berg am Laim, underground.

Like almost all rivers in Germany it was regulated in the past and redirected according to need, eg around the airbase Neubiberg around. Meanwhile, longer sections of the riverbed were renatured, as for example in the landscape park Hachinger valley on the former airfield.

He is currently flowing in the East Park at its western edge along, crosses under the Heinrich Wieland Street and ends after another 120 m in an intake structure with automatic dirt rake. An infiltration basins adjacent to the intake structure is designed to hold at high tide the water that the intake structure can no longer take in order to prevent flooding. Since 1933, the creek is fed from this place underground through a concrete pipe up to the railway triangle south of the A94 at the southern tip of the Munich district of Bogenhausen and feeds the beginning there Hüllgraben. The pipe runs under the first Kamp wall street, pivots on the Hachinger Brook Street east to St. - Veit -Straße, under which it leads north to the confluence with the Hüllgraben. The Hüllgraben flows in John kirchener moss in the Abfanggraben, which flows into the Middle - Isar- channel at the power plant Neufinsing.

Since the 1980s, there were among the inhabitants of Berg am Laim repeatedly demands to transfer the 3.8 km long river section between East Park and Hüllgraben to the surface. From the intake structure to the pavilion at the metro station Josephsburg at the Kreillerstraße already exists, the dry creek bed, but the originally planned exposure to the Federal Garden Show 2005 failed because of the lack of budgetary resources. 2009, the excavation was again the subject of a meeting of citizens, without any concrete developments would have resulted (as of 2010 ).

The name of the creek is derived from the Bavarians Hacho who built between the 5th and the 8th century along the watercourse settlements.

Previously dried up the source of about every seven years and appeared a year later on; also the seeping of the stream you could previously not explain. For this reason, have grown up around the Hachinger Bach some legends in which the devil for the disappearance of the stream is being blamed. Other variants act of a mill on the stream to which it is to have given an inheritance dispute between two sons. Because they could not agree that God can dry up the creek in front of the mill, so that the mill was useless.
