The Gänsmühlbach is a 17 kilometer long Mühlkanal to the left of the lower course of the Isar in Lower Bavaria , which flows into the Längenmühlbach on the eastern edge of Landau an der Isar in the district of Dingolfing-Landau .
geography
The Gänsmühlbach mostly has widths of only two to three meters.
course
The Gänsmühlbach is diverted below the weir at the Gottfrieding hydropower station a little downwards from Gottfriedingerschwaige at Isar river kilometer 41.44 to the left from the drainage ditch parallel to the Isar . This flows into the Isar a little below and therefore already runs within the left flood dam. The Gänsmühlbach already flows after about two meters in an underpass to the outside of the flood dam. From then on, the water often only runs a short distance, a maximum of 1.2 km, to the left of the river, which runs very straight on the common section in an east-northeast direction.
After a flow distance of 17.29 km - as the crow flies , the mouth is only 13.2 km away from the origin - it enters the Längenmühlbach from the right on the northeastern edge of the locality of Landau an der Isar , a longer and older left-hand Mühlkanal of the Isar which is diverted significantly further up the Isar at the Altheim hydropower plant . Because this runs at a greater distance, but still quite close to the Isar, the Gänsmühlbach is its only right tributary. Former natural left tributaries to the Isar in this area now generally feed the Längenmühlbach, which is why the Gänsmühlbach, which is closely framed by this and the Isar, has no significant natural tributaries. The largest inlet Lautergraben , on the official Rosenauer Ableiter map , comes from the left, however, it tunnels under the Längenmühlbach and flows only 138 meters further south-east into the Mamminger area near the municipal boundary to Gottfrieding. The official map shows a transition from the Längenmühlbach itself to the Gänsmühlbach 350 meters above the Lautergraben tunnel; here the two mill streams are only a good 50 meters apart. This ditch can already be seen on the historical land map of the 19th century, but does not end there in the Gänsmühlbach, but in an arm of the Isar.
On the middle course almost 300 meters after the Meisingermühle, the Zwerchgraben tunnels under the Gänsmühlbach from the left, after having crossed the Längenmühlbach in a culvert 1,300 meters further upstream and northwest . A little after the second change of side on the Gänsmühlbach, it continues to flow as aging up to the urban area of Landau an der Isar. It flows into the Isar a quarter of a kilometer after the border and about half a kilometer from the town's outskirts.
In the past, the Gänsmühlbach was diverted from the Isar around 1800 meters further downstream than it is today at river kilometer 39.6. At that time it was 15.9 km long. Since the Isar deepened more and more after it was straightened, the diversion had to be relocated upstream.

Mills and hydroelectric plants
At the Gänsmühlbach there were four mills or hydropower plants, of which none have been in operation for decades due to reduced water flow:
- Meisingermühle (Waibling, Pilsting Market)
- Stadlermühle (Harburg, Pilsting Market)
- Rauchmühle (Landau an der Isar)
- Gansmühle (Landau on the Isar)
The smoke mill has been standing still since around 1940. In its place, a cabbage mill is drawn in the original position sheet 505 Gaenacker from 1837 . The water there is called Gans-Bach .
In the justification for the decision of the Landau / Isar district office of March 5, 1934, No. 513, re: Meisingermühle dam and power plant , it can be read: 2 mills were closed a long time ago. Accordingly, the Gänsmühlbach drove six mills in an even earlier time.
history
When the Gänsmühlbach came into being cannot be precisely determined, but Schweitzer (1957) limits the time to the 1830s. At that time they wanted to relocate the ship mills located on the lower Isar to Mühlbach streams. A map of the city of Landau an der Isar of the District Court-top recorder from 1798 shows the other hand, that it at least there at this earlier time already a goose Muehlbach was, until his entrance into the moss Mühlbach (now length Mühlbach) the truce limited to the north.
In the second half of the 19th century, the upper reaches of the Gänsmühlbach was relocated several times because the Isar had shifted its river bed.
In the repertory of the Topographisches Atlasblatt Landau from 1846, the water is listed as Mühlbach (Kleiner) . It also says: ... separates from the Isar at Goben, flows northeast, merges with the large Mühlbach at the Weindlschwaige.
- Bridges: 1 hour at the Oelschlag.
- Mills: the Stahrlmühle (Stadler Mühle)
Accordingly, only one mill was in operation in 1846.
Sport fishing
The Gänsmühlbach is an association water of the district fishing club Dingolfing eV, but is currently classified as uninteresting for fishing .
