The Binzenlöchlesgraben is a brook in the Kraichgau in the municipality of Neulingen ( Enzkreis ) and the city of Bretten ( Karlsruhe district ). The water from the upper reaches usually sinks into the karst of the Bauschlotter Platte and mostly emerges again via the Enzbrunnen on the Salzach . In the dry valley below the sinking , a ditch called Eng runs , which also flows into the Salzach.

Upper course Binzenlöchlesgraben

The Binzenlöchlesgraben is created on a rain overflow around 500 meters west of the outskirts of Bauschlott and the castle there . At least since 1963 and at least until 1987 Bauschlott had its own sewage treatment plant , the receiving water of which was the Binzenlöchlesgraben. Today a sewer pipe runs through the valley to Bretten and on to a central sewage treatment plant near Bruchsal - Heidelsheim .

Taking a northerly direction of flow, the Binzenlöchlesgraben runs for around one kilometer through the fields of Bauschlott. Two unnamed ditches flow from the right, which drain the area north of the village and west of the federal highway 294 (Bretten– Pforzheim ). In the lower part of this section, west of the Binzenlöchlesgraben, lies a narrow strip of forest, behind which, around 400 meters from the water, is the deserted pond . The place was last mentioned in 1432, it was probably largely uninhabited by that year.

Sinking

With full entry into the Hinterbach forest area , the layer boundary between the Lower Keuper and the Upper Muschelkalk goes hand in hand ; the water of the Binzenlöchlesgraben begins to sink into the crevices and crevices of the shell limestone .

A biotope mapping characterizes the valley of the Binzenlöchesgraben in the Hinterbach forest area as a partly widened, meandering blade that is planted with hardwood in a very natural way. The creek bed is around one meter wide, earthy and stony and is only temporarily traversed.

After almost a kilometer, the water leaves the forest and flows for around 400 meters through the eponymous Binzenlöchle (also Benzenlöchle ), an area that is partly used as meadows, partly as fields. The name is first recorded in 1539 as Bentzenlöchlin , the spelling Bentzenlöchle and Bintzenlöchle have been handed down from the 18th century . Presumably it is the name of a property owner or a short form of Bernhard. At Binzenlöchle there are two deep wells for the Nussbaum water supply, completed in 1926 and 1952 . In 1972, the Binzenlöchlesgraben was laid in concrete half-shells in order to protect the wells from contamination by sewage from the building site.

Below the Binzenlöchles the ditch enters the Great Forest and crosses the border between Neulingen and Bretten, which is also the border between the Enzkreis and the Karlsruhe district . According to a biotope mapping, the temporarily aquatic body of water initially runs in a narrow blade that is up to 3.5 meters deep in the near-natural forest. The creek bed is 0.5 to 2 meters wide; alternate between loamy and stony sections. The blade changes to a valley on the sole .

In the representation of the official digital water management network (AWGN), the Binzenlöchlesgraben leaves its valley about a kilometer below the Binzenlöchles to the right, crosses the ridge on which the federal highway 294 runs, and flows from the left in the Bretten district of Ruit into a twisted section of the Salzach . In the topographic map, the water ends about one kilometer below the Binzenlöchles, with the last kilometer shown as only occasionally bearing water.

In June 1963 a combined marking experiment was carried out with 2250 grams of uranine and five tons of rock salt . At that time the water sank roughly in the Binzenlöchle. The main exit takes place after three days in the Enzbrunnen - a karst spring that lies just under four kilometers north of the Binzenlöchles directly on the Salzach. After 39 days there were traces of leaks in a deep well in the city of Bretten, which is located on the southern edge of the city in the Salzach Valley. From the results of this and other marking experiments it is concluded that there are two interconnected stratified groundwater horizons in the Upper Muschelkalk. The upper one lies in the heavily karstified lime and feeds the Enzbrunnen, the lower one with slower drainage is opened up in the Bretten deep well.

Below the sinking is a dry valley , in which the forest engineering base of the city of Bretten in the Great Forest is located around 2.5 kilometers north of the Binzenlöchles . According to the AWGN, a trench called Eng begins at the base . The topographic map shows two rivulets a few hundred meters long that unite at the base and flow north. One trickle follows the dry valley, the other, coming from the left, is created on two artificial ponds created in 1979 in the Saubrunnen forest area .

The Eng leaves the Great Forest a good kilometer north of the forest engineering base; here is the Bretten zoo on the left and a climbing forest on the right. The corridor In der Enge, which gives the water its name, borders the forest . The field name stands for a narrow, narrow valley; it is first mentioned in 1463. There is evidence of a narrow ditch for the year 1813 . The Eng follows the Salzhofen road to the north and passes a veterinary clinic and a farm. This part of the city of Bretten is also called Salzhofen ; it goes back to a village of Salzhofen first mentioned in 1283 , which later became deserted.

Almost 100 meters north of the crossing under the district road 3568 from Bretten to Sprantal , the Eng flows from the right into the Hungergraben , which flows into the Salzach from the left after a good 500 meters. The Salzach and Weißach merge in Bretten to form the Saalbach , which flows into the Rhine some 40 kilometers north of Philippsburg .

In June 2016 and apparently also in June 2015, flooding on the Eng came after catastrophic heavy rain , which particularly affected the farms in Salzhofen. In the sinking area below the Binzenlöchles, the water flow up to two meters high in June 2016 cleared out the blade base and the adjacent walls and deposited large banks of coarse rock. The heavy rain had similar consequences in one of the side blades. Pictures published in a regional news portal show flushed or displaced pipes of a culvert and piles of dead wood .
