The Vincenzgraben is a left tributary of the Black Elster in Saxony . It is the main drainer of the NSG Dubringer Moor .
geography
The Vincenzgraben rises north of Zeißholz on the Zeißholzer Höhe. It flows on its upper course in an easterly direction through the Zeißholz colony and through Scheckthal and north past Dubring . At Dubringer Berg ( 161 m ) the brook takes a north-easterly direction and flows through the St. Mariensterner Klosterforst and the Dubringer Moor, where its course runs west past the Neudorfer pond area (Mittelteich, Lilienteich, Neuteich, Wusteteich). There the Vincenzgraben reaches the Hoyerswerda city area south of Michalken . The lower course of the stream runs through the village of Dörgenhausen . After 10.3 km the Vincenzgraben flows into the Black Elster opposite Groß Neida .

Revitalization
With the start of intensive mining near Zeißholz, the Vincenzgraben was used in the 20th century as the main receiving water in the area to drain the pit water. The Streitteich and the Große Mühlteich in Scheckthal were drained to lower the groundwater in the Clara III pit. The Vincenzgraben is heavily contaminated with heavy metals due to the introduction of water from Lake Clarasee and swamp water from the Grauwacket opencast mine in Oßling. In order to protect the Dubringer Moors and the Schwarzen Elster, a new regulation of the receiving water in the mining rehabilitation area is taking place, since it is not possible to discharge the mine water for neutralization into the Clarasee. The rehabilitation measures include the safekeeping of open underground routes, the cleaning of the trench and the removal of obstacles, the opening of piped sections and the partial relocation to a new route. The aim is to develop the water balance as naturally as possible.
Due to the high sulfur content of the Dubringer Moors, there is also a strong sulphate input into the Black Elster via the Vincenzgraben.
