The Kroll Bach in the Moosheide

The Kroll Bach is an orographic right tributaries of Glenne in North Rhine -Westphalia, Germany. It has a length of 15.3 km.

River course

The source of Kroll creek is located approximately 153 meters above sea level within the training area Senne and thus on the grounds of a military restricted area. As with most springing in this area waters a dry valley joins even when Kroll creek above the headwaters.

The waters of the flattening of the Teutoburg Forest upstream Senne landscape flows following in southwestern direction within a Kastentals from, happened after about three kilometers flow path, the former Kroll mill and then passes through the southern edge of the nature reserve Moosheide and flows through there one for the purpose of the sand trap built pond.

After crossing the main highway 33, the Kroll Bach turns to the settlement area of Hovelhof and reached the eastern edge of the village a Flussbifurkation about the flows that designated as Schwarzwasserbach right arm in a westerly direction into the Ems. The Kroll Bach performs during the further course southwest to Hovelhof over and reached underneath the town around the 121.8 -hectare nature reserve Erdgarten - Lauer meadows. Within these consisting of wet meadows and alder forest protection area of ​​the stream breaks the city of Delbrück.

To the east of the district east country is a first channel-like connection to the only slightly further south running and designated as Haustenbach in this area Glenne, but the Kroll Bach follows the Glenne in an approximately parallel course over another 2.5 miles and leads finally to the south of the east country at the level of water work into this.

The Kroll Bach overcomes during its flow path a height difference of 58 meters, thus results in an average bed slope of 3.8 ‰.

Water quality

Since the Kroll Brook in the upper reaches is within a restricted area, the water quality is at least there is hardly affected due to lack of agricultural or industrial discharges. The water structure shows in the upper reaches a largely natural state. With the entrance of the river into the Hövelhofer settlement area the water structure quality but decreases significantly and is classified as markedly to severely damaged in some sections.

History

As a result of sedimentation, as well as by the action of an elongated jam barrier Moränenwalls the Kroll Bach once had a grid-like structure of individual streams, ponds and swamps and labored through this inland delta long time the development of Hövelhofer town center. Even in 1930 lapped a part of this streams the present village. However, it began in the early 19th century with a channeling of individual Kroll creek arms and laid in this episode the northern arm dry. Some remnants of the formerly fed by this arm ponds and the stream bed are still recognizable today.

Etymology

The name of the creek Kroll was due to the shape of its inland delta probably in reference to the term " Krull ", which originally designated a fan-shaped hairstyle; or to the name " rollers " for a fan-shaped ruched kind of towels and hoods.

However, the Kroll Bach was apparently a long time a nameless waters. This is suggested by, among others, the name of a before 1700 incurred by the riverside row settlement, which was only referred to as " pond water"; and even in 1828, the former a cadastral map located at Kroll Bachstraße with the simple term " waterway " from. The name of the water body as " Krull water " is being used for the first time in a map from 1805 ( see figure).
