Hoyerswerdaer Schwarzwasser

The black water at Shell joke

The black water ( Upper Sorbian Čornica ), called for better differentiation from other rivers of the same name, about the Ruhlander black water, also Hoyerswerdaer black water is a right tributary of the Black Elster in Saxony.

Course

Sources and headwaters

The black water is formed on the northern slopes of the Lusatian hill country from different source streams.

The main source is located about 200 meters north of the summit of the High rooster to 419 meters. From here, the river first flows north to Tröbigau, where it combines with two other spring-fed streams, on the one hand from Tröbigauer butter mountain ( 388 m) and the other from the stocking (derived from the Slavic tok = river ) between Tröbigauer mountain ( 401 m ) and Virgin Stein ( 373.2 m ) can occur. Next it flows westward through Schmölln and then to the northeast by Demitz - Thumitz. Last place near the brook, before it unites with the other black water, Rothnaußlitz is. Immediately before Schmölln and between Demitz - Thumitz and Rothnaußlitz the creek is dammed in smaller basins.

Another source stream is the Naundorfer water, which is sometimes referred to as black water law. It rises on the eastern slopes of the High rooster to 391 meters above sea level, only about a kilometer away from the main source, but from there flows in an easterly direction through Obernaundorf and then north through Cossern, Zockau and Neuspittwitz to the confluence with the main river near the main road 6 at Spittwitz.

Outcome

The further course of the river runs north through the town Spittwitz - there flows the silver water - and by Nedaschütz. Shortly after Spittwitz and again before Nedaschütz the valley narrows to a rocky gorge, the Nedaschützer scale. This is typical of the Upper Lusatia landscape form a Engtales arose during the Elster glaciation. The meadow valley between them should be flooded by a dam once. In Nedaschützer valley, about 200 meters above the fish Nedaschütz remnants of the already begun diversion tunnel for the black water are at the closest point to see. In Spittwitzer district scale were abandoned by the inhabitants of three of four houses. After the decision was made to build the Bautzen Reservoir, the project was stopped.

After passing under the motorway 4, where the Long Water opens, follow the places Prischwitz, Sollschwitz, Dreikretscham, Saritsch and Neschwitz. In the latter, the Pusch witzer water flows. The black water is almost completely regulated in this section. Below Neschwitz the floodplain is about 500 meters wide, while the actual river bed is 5 to 10 meters lower than its surroundings.

There follow Zescha and Königswartha with its ponds. The flood plain narrows to Königswartha at about 200 meters and widened during the transition to the Lusatian glacial valley below Königswartha again at 500 meters. At this point the river is incised only one to two meters in the floodplain.

In Königswartha several side arms from the black water branch off, including the Warthaer black water, which feeds many ponds between Caminau, Warta and Koblenz and reunited in Knappensee with the black water.

Lower reaches and estuary

In the further course is large Särchen. Here, the black water feeds the Knappensee, the carbon-free opencast lignite opencast mine Werminghoff at Knappenrode. Previously, however, diverted through a lock of the majority of the water in the black moat, a voltage applied to operating times of the pit diversion of the river. This leads from United Särchen west past the Knappensee.

The mouth of the black water in the Schwarze Elster is due to the side arms of both man-made rivers in three different places:

First, either directly south of Hoyerswerda Schwarzwassergraben on the Wudra, a straightened arm of the Schwarze Elster. Because here comes together most of the water from both black water and Schwarze Elster, this confluence can be considered as a regular black-water estuary.

Only a few hundred meters later, for small Neida, the flow also combines with the historic main branch of the river Schwarze Elster.

The original black water flows to the drain from the Knappensee by Spohla and Maukendorf to Hoyerswerda, where it is directed to the Neustadt in the Black Elster. The original junction was moved; in its place today is the housing estate Hoyerswerda -Neustadt. The present estuary is located directly on the flow of the river Schwarze Elster by the federal highway 96, making it the last of the three confluences.
