The shepherd Bach, also Shepherd ditch, is a stream in the Lower Harz in Saxony- Anhalt, which flows through the Shepherd reason and right leads into the Uhlen stream, which drains to the Selke.
Origin and Evolution
The shepherd creek rises in flood -forming region of the resin near the home mountain in a source dump, as is typical for the lower resin. It is located approximately in the center of the triangle from the middle mountain, the mountain of flesh and the Fitzgeroder Heimberg.
In the upper reaches, in the field of Bleck Turned out, the creek has a left and a right-side inflow. Approximately half the length of the barrel reaches the Bachaue with about 200 m of their greatest width. Around here measures in an open Trapezgerinne at high water, a pressure sensor water level and a Doppler ultrasound sensor speed. At 1,755 kilometers flow is a 60 ° overflow weir ( Thompson weir).
In the lower reaches there is an underground dam. The total 2180 m long river flows at an altitude of 393 m above sea level. NN from right in the middle reaches of the creek Uhlen, shortly after it has received the Great Uhlen creek in storage pond at Forest House Uhlenstein.
Hydrological situation
At the headwaters of the creek Shepherd 1972 a total of 21 drains were created. Already the field block of the source well is dewatered in the Shepherd stream. Since 1974, mining activities led (development of a Flussspatlagerstätte ) to a local lowering of the water table. The natural flow of water with soil moisture increase ended. Since there are dry periods and episodic sudden flash floods, which the chemical and biological water quality is very impaired.
In the course of the safe keeping at the end of the mining activity, the groundwater level rose again and reached in 1999 a new stable state, but which is different from the original state. The shepherd creek falls temporarily dry in periods of low rainfall, but up to 20 m distant meadows are regularly flooded at high tide.
