The Höllachbach is about 3 km long river in the Natural Environment Backnanger Bay and in the community Leutenbach in Baden-Württemberg Rems-Murr , who in the suburb Nellmersbach arises and even with people stream in from the right and northeast in the Murr influx Buchenbach flows.

course

The origin of the Höllachbach and its uppermost course cannot be seen on site, as the entire section of the stream was channeled through Nellmersbach in the 1950s and 60s. The source is likely to be roughly at the level of the Nellmersbach train station. Here, between Wiesentalstraße and Robert-Bosch-Straße, which branch off in the same direction from Bahnhofstraße, a walkway running westwards with the street name Beim See begins , which may be a reference to the former headwaters. The twisted canal of the Höllachbach runs roughly under this path to the sports field on both sides of the crossing Schwalbenweg.

There it unites with the Brücklesbach coming from the northeast, which is also largely canalized . This begins as a permanently water-bearing dirt road about 200 m northeast of the sports field at about 315  m above sea level. NN , is slightly shorter than the Höllachbach upper course, which is just over half a kilometer long, and its catchment area is only a third as large as its 0.5 km². The combined brook then continues through the village in a south-westerly direction; the small valley basin and the street Am Brücklesbach still bear witness to the original course. On the southwestern edge of the village it then reappears as the Höllachbach .

The brook runs about 300 meters further on at about 291  m above sea level. NN with the only 0.6 km long right Sauäckergraben , which runs all the way in the open land and drains a partial catchment area of ​​0.4 km². After that, the Höllachbach flows a further 1.6 km in a south-westerly direction without any further damming, passing a small pond between trees on the left bank of less than 0.1 hectares with reed beds before crossing a field path and is then two hundred meters from one dense wood gallery. Finally it flows into about 270  m above sea level. NN on the north-western edge of Leutenbach from the right into the Buchenbach, which is moving here about northwest.

In its last 400 m the Höllachbach mostly seeps away and only carries significant amounts of water after heavy rainfall. This stream shrinkage has only been observed for about three decades; previously the stream had constant water up to its mouth.

landscape

The Höllachbach and its two tributaries run outside of the villages in scarcely deepened valleys through a landscape dominated by fields and a few pieces of trees. In the vicinity of the confluence of the Höllachbach and Sauäckergraben rivers, there is a clay pit on the right hill, which opens up the loess sediment typical of the landscape . The Höllachaue landscape park follows shortly afterwards , in which the stream has been renatured on a shorter section and a biotope has been created. This was a central compensation measure for the land consumption by building projects of the municipality.
