The Schwarzach is a 10 km long river in the Bavarian Forest and the adjoining Danube Valley through the Lower Bavarian districts of Straubing-Bogen and Deggendorf , which flows into the Danube from the left and north-northwest at Mariaposching on the district border . The longest drainage routes in their river system are almost 20 km in length. The Schwarzach is a third order of water .

geography

course

It is created by the confluence of the Rohrmühlbach , which is approaching in its direction of flow, with the longer left Waldbach south of Markt Schwarzach and initially flows in a south-easterly direction past Kumpfmühl, Aimühl, Riedhof, Haidmühle and Haid. There at the inflow of the longest upper reaches of the Bernrieder Bach , again from the left, it leaves the Bavarian Forest into the Danube valley and runs almost south from now on. It passes Anger, Aschenau, Hochstetten, Mösl, Moosmühle and finally flows into the Sommersdorfer oxbow lake at Sommersdorf .

The last 3 km the Schwarzach flows in the artificially created Schwarzach-Sulzbach-Ableiter, which leads from the crossing under the A3 to the newly created estuary; the old one was about a kilometer further down the Danube on the outskirts of Kleinschwarzach at the end of a meandering section through which the Sulzbach flows today .

Catchment area

The Schwarzach drains 88 km² on the south-west slope of the Bavarian Forest and in its valley level to the Danube between Bogen and Deggendorf . Adjacent drainage areas are that of the arc Bach to Kinsach in the northwest and north, the Black Rain -Zuflusses Teisnach in the northeast. Further to the south, beyond the eastern watershed, the Mettenbach drains its tributaries directly to the downstream Danube. Behind the south and south-west borders of the Schwarzach catchment area, only smaller bodies of water flow into the Danube valley floodplain or from the low foothills of the Bavarian Forest.

The highest section of the total watershed limits the sub-catchment area of ​​the Bernrieder Bach to the northeast, here it has a maximum height on the ridge of the Rauhen Kulm against the Teisnach of 1050  m above sea level. NN . The largest elevation, however, is the 1089  m above sea level. NN high peaks of the Hirschenstein at the catchment triangle of Schwarzach, Teisnach and Bogenbach a little further to the north-west.

Tributaries

In its upper section, still in the Bavarian Forest, longer source brooks and tributaries usually flow into the name course from the left and from the north to the northeast, the top sources of which are in and around the Schwarzacher Hochwald and higher up on the Hirschenstein at up to 1020  m above sea level. NN .

Communities

The Schwarzach itself flows through or touches the municipal areas of Schwarzach, Niederwinkling , Mariaposching and Offenberg .
