The Mordgrundbach (also called Mordgrundwasser or Stechgrundbach ) is a tributary of the Elbe in the east of Dresden .
course
The brook rises in the Dresden Heide district ( Loschwitz district ) and flows in a westerly direction through the Mord- or Stechgrund to the Elbe. After 3.5 kilometers of flowing, the stream flows orographically right into the Elbe in Loschwitz .
The stream runs almost its entire length as an open, largely natural body of water. Only a short section of 300 meters in the headwaters is piped. The 2.6 square kilometer catchment area of the Mordgrundbach lies in the south of the Dresdner Heide and is more than 80 percent dominated by forest. The source streams ensure a high iron content in the water, which under the influence of oxygen precipitates as iron hydroxide and forms rust-colored coatings in the water bed. The name of the Eisenbornbach , which also rises in the Dresdner Heide, is due to this ossification .
After the confluence of the forest garden ditch, the Mordgrundbach flows through the Stechgrund source moor . After the inflow of the Sandquellbach and the Weißiger Graben, the Schwestern and Degele springs also contribute to the water level of the Mordgrundbach. The last tributary before the mouth is the confluence of the pond base source. The crash structure of the Mordgrundbach at the confluence with the Elbe represents an insurmountable obstacle to migration for aquatic organisms .
Origin of the term "Mordgrund"
A romantic legend has grown up around the name of the reason for the murder . According to this, the murder reason is said to have its name after an event at the end of the 13th century. At that time two lovers (Elsbeth von Clohmen and Benno von Birken) are said to have killed themselves with a stab in the back after the young and beautiful Elsbeth was forced by her father to marry the Bohemian Count Lodomar Kinsky . Before Birkens died, he killed the Bohemian count with the sword in a dispute.
The possible origin of the name in the German colonization as Markgrund , which means something like Grenzgrund, is less legendary .
According to Heinrich Meschwitz , the name goes back to the old name Moorgrund .
Water condition
Due to its catchment area of less than 10 square kilometers, the Mordgrundbach is not a separate body of water according to the European Water Framework Directive (WFD). The brook belongs to the water body type 5.1 (WFD): "Fine material rich, silicate mountain brook".
natural reserve
The catchment area of the Mordgrundbach belongs to the landscape protection areas of Dresdner Heide and Dresdner Elbwiesen and Dresdner Elbe altar . The area where it flows into the Elbe lies in the Elbe Valley FFH area between Schöna and Mühlberg .
Springs and moors
There are six springs in the catchment area of the Mordgrundbach. The best-known are the Degele spring and sister spring , which only have periodic water supply and were opened up in 1884 . These have their source areas in the beech forest and are flow sources rich in fine material. The name of the Degele spring goes back to the baritone singer Paul Eugen Degele (1834–1886), who lived on the Weißer Hirsch and donated the spring version.
The Stechgrund spring moor in the upper reaches lies in a dune depression in the forest with buckthorn bushes and individual birches . There are lush Torfmoosbestände , stocks of the Philodendron belonging Kalmus and just below occurrence of rare Arctic somatochlora .
The pond base source is a partially natural source area in the beech forest. It consists of a spring complex of several flow sources on the side of a spring pond. The spring was uncovered in 1926 when a ski jump was built. The hill doesn't exist anymore today. The source is classified as a flow source rich in fine material, as sandy substrate dominates. The spring pond serves as a spawning area for the agile frog . The water quality of the spring pond is impaired by the formation of hydrogen sulfide due to heavy fall foliage.
Buildings on the Mordgrundbach
Stechgrund Bridge
The Diebsteig forest path crosses the Mordgrundbach over the Stechgrund bridge. The bridge, already mentioned in 1572, was rebuilt in 1969 and completely refurbished in 1996.
Water catchment and water house
Shortly behind the source of the pond, there is a water catchment and a water house in Mordgrund. Built in 1850 water to provide over wooden pipes Albrechtsberg Castle with process water for the fountains. About halfway between Albrechtsberg Castle and Lingner Castle , the water pipe ran under Bautzner Strasse into the park. The additional water catchment was built in order to meet the water requirements of the Dinglinger and other Loschwitz properties. The tube ride out of the Mordgrund is the only historical aqueduct preserved in its original state in Dresden and still supplies the water features, fountains and fountains in the Albrechtsberg Palace and Park.
Mordgrundbrücke

Bautzner Strasse (part of Bundesstrasse 6 ) leads over the Mordgrund Bridge over the Mordgrund on the edge of the Dresdner Heide. The bridge was first mentioned in a document in 1420. In 1466 it was called "Mordtgrund".
The bridge was built of stone in 1587. In 1784, however, it was rebuilt as a wooden bridge and again made of stone in 1828. Near the Mordgrund Bridge is the so-called Napoleonschanze, which was built by Prussian troops in 1758 and used as an observation post in 1813. Not far from the bridge is a statue of the centaur Cheiron , created in 1902 by Otto Petrenz at the confluence of the Moritzburg-Pillnitzer Weg.
waterfall
Between the water catchment and the Mordgrundbrücke there is an approx. 2 meter high waterfall built in sandstone with an adjoining water basin, which is already recorded in maps from the 19th century. The water basin is accessible via a ramp. The historic pond path, symbolized by a fish, led over the waterfall up to the Lahmann sanatorium . After the restoration of the system in winter 2010/2011, a rainwater drain from the area of the new residential area in the former sanatorium was connected to the waterfall in 2015.
