The Deutergraben is an approximately 4¼ km long right and western tributary of the USA on the western edge of the Hessian Wetterau ; about ver km from this it is piped.

geography

course

Up, today, at Deutergraben

The Deutergraben rises at a height of about 234  m above sea level. NHN west of Bad Nauheim in the district of Ober-Mörlen , northeast of the Winterstein and north of the FFH area on the 258.9  m high Ockstädter Galgenkopf on an intensively arable cleared area.

In historical times, the Deutergraben on the large cleared area at Hofgut Hasselheck received a different course several times in ditches or pipelines made for this purpose. Before the construction of today's BAB A 5 / E 451 , it had its source (s) one kilometer west of it on the Winterstein. Then he sprang from the Schäferborn . Today the source lies in a ditch that continues northwards via piping on a dirt road, an old wine or wagon route known as the (Old) Rosbacher Strasse . Today, the Schäferborn no longer pours heavily enough that the ditch in which it lies must have a drain; rather, its water dries up a few meters below the source. An underground drainage pipe is currently shown as a source branch in maps. In the terrain it appears as a sequence of sewer shafts , a wooden stick to mark the mouth in the Deutergraben and the end of the drainage pipe itself.

View up and to the Schäferborn

The ditch that now carries water reaches the edge of a mixed forest with a very high proportion of conifers already 125 m below the beginning of its initially roughly northeastern course after a passage under an unpaved field path. Several springs in the ditch feed it more water, which after about ⅓ km reaches an old Roman hill hidden in the forest. Another 175 m further, his run ends at the edge of the forest and he turns in a 90 ° curve to the left of the open field. To the west of an unpaved field path, the Deutergraben, lined with trees, flows in curves northwards and after almost 100 m from the left at a wooden stake takes on the inflow of a drainage pipe. 50 m further on it disappears under a pile of stones. Another 50 m further there is a visible inspection shaft in the ground. Another stream flows into the northward flowing water stream from the right, i.e. west. Another inspection shaft of the same type is located 175 m further. From there, the water seems to be led under the dirt road to a third inspection shaft, into which drainages flow, then underground to a pasture with a high seat , which is just 100 m away. From there it flows again above ground in a trench with an approximately triangular to trapezoidal profile. So it flows eastwards for about 200 m to the mouth of the Stuhlgraben in the Flur Auf dem Dammacker , the local border and the Bad Nauheimer Hochwald .

Marked inflow

On the western edge of this department of the Bad Nauheim city forest, the Stuhlgraben turns 90 ° to the right and south at the end of a culvert under a path that is no longer available, flows at the boundary stones of the former Electorate of Hesse ("KH") and Grand Duchy of Hesse ("GH ") and flows 70 m after the bend from the left into the Deutergraben coming from the west, which also uses a passage under a path that is no longer available. In the Bad Nauheim city forest, a mixed forest, it has cleared a wide flood basin called Muckergraben , with many bulges through which it now meanders. Towards the Dietersbrücke , old and no longer usable bank fortifications, bed sills and a fortification of the stream bed can be seen. The stream becomes straight here; possibly the change in character has to do with the mining of turf iron ore in the 1870s north of this section. On the eastern side of the forest path to the Waldhaus inn and the "Hochwald" forester's lodge on Rosbacher Straße , the Deutergraben now takes surface runoff in a concrete trough from the trenches accompanying the path. From here a long passage leads under the forest path to the forest ponds . At its outlet there is an elaborately walled canal, below which a cast iron pipe with a shutter protrudes from the forest floor from the right. The Deutergraben can again form a bulging hollow here, which is now clearly deepened, a few meters lower than the path accompanying it to the forest ponds, and meander in further loops.

Run the Deutergraben through this apparently closed slide in the uppermost of the Bad Nauheim forest ponds, view from the side of the grave

At about 1.85 km the water flows through an apparently closed slide to the right into the first and, with almost 1,000 m², the smallest of the shallow forest ponds created in 1736 as a summer water reservoir for brine operation (deepest point in each case in the outlet area) Sign as "amphibian pond" is designated. Through flushed underground channels in the dam, the inflowing water flows past Mönch and Fluttor into the inlet of the 1,300 m² larger central pond. At its larger flood gate with monk, the embankments to the last and largest of the three ponds are reinforced by masonry. This last pond with an area of ​​2,800 m² drains under the path on its dam crest (about two meters above the pond floor). The dam itself is leaking, a trench at its foot leads the seepage water into the pond's underground outlet.

This upstream ditch is also the end of an overflow ditch that can absorb excess water from the Deuter ditch. It first leads from the uppermost pond along the path from the Dietersbrücke and then turns left, northward, into the deciduous forest. There it forms loops in wide hollows and ultimately meets the footpath from the Hochwald Clinic to the forest ponds and becomes a collector of the already mentioned seepage water. The culverts on the hiking trails are obviously old and could still come from the time the forest ponds were built.

The Deutergraben now accompanies a grave land on the right . A grassy area stretches to the left as far as a path; further north is a large new building area from the end of the 20th century, the Sichler , named after a former brickworks site including pits for clay mining (which were filled with rubble, household waste and toxic waste), earlier Called Siegler , pronounced like "Siechler" in Hessian. After a little wood, the ditch now flows through a meadow orchard with old tall trunks, where a sewage pipe comes from the Sichler, and arrives at Landesstraße 3134 or Homburger Straße .

The right bank of the Deutergraben at the Bad Nauheimer Friedhof

It crosses under a modern concrete bridge and now flows past the southern Jewish burial ground of the cemetery, where its banks are partially fortified. To the east of the cemetery up to Kreisstraße 13 or Friedberger Straße , orchards, gardens and arable land have been rebuilt since spring 2018, around km 0.5 to km 1.0. According to the planning, the stream should flow in a strip 20 m wide, free of buildings, and part of the surface runoff should be fed to it via cisterns. Regardless of this, the stream has been seeping away about 50–100 m below the cemetery for decades. His mostly dry ditch, on the other hand, continues under the county road eastwards, then on the southern edge of an older new development area, and reaches the large parking lot of the Usa wave pool and the pool itself, both of which are on the right. This is followed by a small, tree-lined sports field on the right bank and a park landscape on the left bank, which separates a row of high-rise buildings from a row of Grabeland and the United States, along with their promenade along them. At the end of the promenade, a beveled concrete pipe falls from half a meter above the water level into the trapezoidal profile of the USA.

Future planning

For decades, a bypass of the federal highway 275 from Ober-Mörlen and Bad Nauheim from the western OU Friedberg of the federal roads 3 and 455 has been planned roughly parallel to the 20 kV overhead line that crosses the Bad Nauheimer Hochwald and at Hofgut Hasselheck as well as the current one Location of the Wetterau service area to the north with its own connection to the A5 / E 451 leads into the Usatal, to the west of Ober-Mörlen on the B 275, which was completely renovated in the 2010s. Long plots of land have already been acquired for this purpose and the corridor has been cleaned up. The Deutergraben would have been affected. More recent plans of the FrankfurtRheinMain regional association in its land use plan provide for a different course, which would hit Stuhl- und Deutergraben if it were to be realized. The reason for this may be the relocation and expansion of the eastern part of the rest area, which has been planned for several years, to accommodate additional quantities of trucks so that the legal requirements for driving and rest times can be complied with.

A new development plan provides for the construction of a pedestrian and cyclist bridge over the USA just south, this is to extend the path that has accompanied the Deutergraben on the right bank since Homburger Strasse.
