River length

According to the State Survey Agency NRW, the total length of the river is indicated at 18.2 km, with the underflow is called from Heiligenkirchen with Wiembecke. In the German base map and the linguistic use of the underflow is, however, referred to the Upper Mill as Berlebecke and below it as a bone Bach. For the stretch of river Wiggenbach-Berlebecke/Knochenbach results in a length of 12 km. The underflow from the confluence of Berlebecke Wiembecke and has a length of 6.3 km, so that for the Wiembecke a length of 11.9 km, for the upper reaches of Berlebecke incl Wiggensbach results in a length of 5.7 km, where the length of the Wiggen Bach is 2.0 km.

History

→ Main article: Friedrichsthaler channel

Already in 1701 the Berlebecke was dammed in the area of ​​the later Upper mill and built by 3 locks under construction management Dutchman Hinrich Kock. The water storage level at that time was 3.80 to 4.00 m. As in 1748, the canal shipping has been discontinued, was erected in 1752 in the sluice of a mill, the Upper Mill, and so found a new use for the old lock, which could be thus obtained. The water of the Berlebecke powered three mill wheels. Moreover, in this period also the weir on the upper water above the mill was built. Before an existing vault bridge a second bridge with three segmental arches was built. The actual dam originally consisted of ten pillars of sandstone between which the wooden boards were inserted vertically adjustable. The mill was in operation until 1958, was shut down and ten years later the restaurant and expanded. At the Upper Mill Brook bone is taken from a part of its water. Prior to the rehabilitation of the land along the Fried directional Thaler channel of the bone creek was dammed just below the weir at the Upper Mill by another barrage and directed a portion of its water in a small tunnel through the right parallel to the bone creek running rampart and to feed the Friedrich Taler channel connects the castle in the center of the old town of Detmold with the " new Palace " and the Friedrich Taler equipment used. As part of the reorganization of Friedrichsthaler plants in 2008 at the Upper Mill Pond was created, which is fed by the water of the brook bone. The effluent from the pond water in turn feeds now the Friedrichsthaler channel. In addition, a large fish ladder has been created and behind the former military created a Sohlgleite that " defused " the old weir.

Flood

In addition to the flood of the century in 1946, which led to enormous damage to rivers and streams throughout north-western Germany, caused a flood in 1998 considerable damage in the catchment of the Upper Werre, including the bone creek. The largest losses were recorded in Detmold Industrial Area West, the mouth region of the bone creek. Due to an increase in the water level of the bone creek to 4 m of the creek overflowed from massive and flooded the basements of numerous companies and residential buildings as well as a transformer station, which led to a power outage. One factor that increased the flooding was the orthogonal impingement of the water of Bach's bones on the Werre, which has a lower slope than the bone creek. Therefore, there was a backlog of Werre, the flooding increased. As a consequence of this and some weaker later flood the bone Bach was moved to the last 100 meters that he no longer laterally into the Werre " shoots " and now similarly entrains the water of the Werre the principle of a water jet pump. In addition, a few hundred meters was built above the mouth of a large pumping station with two screw pumps, the dry keeps the deeper parts of the industrial area at high water and pumps the water back into the riverbed of Bach's bones.

Environment

Water quality

The upper reaches of the Berlebecke to above Heiligenkirchen represents the cleanest river course in lip and the water quality class I ( 2003) or I-II (2008 ) is assigned. From Heiligenkirchen to the confluence with the Werre the water quality deteriorated to grade II

Limestone areas form the water landscape of the bones creek and its tributaries. Neighboring communities, the city of Detmold and Horn-Bad Meinberg, if one includes the Wiembecke.

The Werre Water Association operates a level at bone Bach, whose data can be accessed online.
