The Heppach is a three-kilometer long stream in the Lendsiedel district of Kirchberg an der Jagst in the Schwäbisch Hall district in northeastern Baden-Württemberg , which flows into the middle Jagst in the hamlet of Eichenau from the left and south .

geography

course

The Heppach arises almost two kilometers south of the village of Lendsiedel between the two forest islands Birkenlehle in the west and Geißholz closer to the east on a side road from the southernmost hamlet of Kleinallmerspann in the district and the city. Its course begins there in the Feldgewann Sefelsbach after a ravine cut in the road inconsistently in the left ditch at about 425  m above sea level. NHN . At the next dirt road junction it turns northwest from this road and runs through the power blade between fields  - despite the name, rather just a small hollow in the terrain - in a slightly changing direction and accompanied by a woody field. Here, too, the approximately one meter wide bed rarely carries water, but during rainy seasons it is fed from drainage pipes from the surrounding fields.

About 0.8 km after its uppermost beginning, the water flows into the 0.8 hectare red pond , also called Lendsiedler See , a reservoir that was only created in the second half of the 20th century and is almost completely surrounded by a belt of trees and bushes is. The water flows over the monk of the pond through the earth dam, the stream turns to the northeast and continues to run between fields on the Gewann Höllenwiesen .

About 1.9 km after the origin mentioned, the Heppach then takes its only significant tributary, the Teufelsbach, from Dörrmenz in the west-southwest on a cross-country lane , which is about 1.0 km long and contributes about 1.0 km² to its catchment area. The Heppach now flows almost to the north and past the village of Lendsiedel on the right slope, more like it at the western entrance to the village at about 347  m above sea level. NHN crosses the district road K 2664 Dörrmenz – Lendsiedel. Behind starts initially between buildings of the town, the new valley portion of an approximately three-quarters kilometer shell - blade with steep, forest tree-lined flanks by which it county road K 2516 to Weiler Eichenau follows the valley of the Jagst down. After the blade has opened to the left valley widening of the river there, the Heppach flows through the hamlet with its three old valley mills on its last quarter of a kilometer, is crossed by the state road L 1041, and then flows right after the return of the channel of the Mittelmühle and a little further in front of the weir of the Gaismühle / Untermühle and the stone river bridge of the Landesstraße immediately below it, behind the house Jagsttalstraße 40 at about 325.9  m above sea level. NHN from the left into the middle Jagst .

The Heppach, which is about 3.3 km long from the mentioned inconsistent origin, loses about 99 meters in height on this route, its mean bottom slope is thus about 30 ‰.

The Heppach flows almost everywhere next to grass or field paths or roads, but in a natural hollow. It has been straightened up to the tributary of the Teufelsbach, the trees and hedges that accompany it on this section have apparently been planted. Then it runs close to nature first in the wide hollow a little west of the southern Lendsiedel, in small meanders and accompanied by natural wood, then even more so in the following underflow ridge, where the wooded valley is also in small loops. He crosses Eichenau between bank walls in a trough typical of the Klingenbach lower courses through the towns on the middle Jagst.

Catchment area

The catchment area is 4.9 km² and, from a natural perspective, is located with its upper area in the lower area of ​​the Haller level of the Hohenloher and Haller level , with the middle to approximately Lendsiedel on the eastern Kocher-Jagst-Riedel then in the middle Jagsttal , both sub-areas the Kocher-Jagst Plains . Geologically, in the highest, southern parts of the catchment area, loess sediment composed of quaternary deposits dominates , below which, as the highest tertiary layer, the Lettenkeuper ( Erfurt Formation ) covers the larger part of the plateau up to the Unterlaufklinge beginning at Lendsiedel, which is cut into the Upper Muschelkalk . At the beginning of the blade there is a small abandoned limestone quarry that is designated as a geotope.

The with about 442  m above sea level. NHN highest point is at the southern tip in the forest area of Oberes Geißholz . From here on, the watershed separates most of the west from the catchment area of ​​the Scherrbach , and finally from that of the much smaller and very unstable Eichenbach . Behind the eastern watershed, the Herboldshauser Bach briefly drains the adjacent area in the area of ​​the Upper Geißholz , followed by the Schindelbach that flows further upwards at Kirchberg . All of these competitors also run roughly north to the Jagst .

The forest in the catchment area is limited to its share of goat wood, next to that of the Birkenlehle and the valley forest in the Unterlaufklinge, but overall it only makes up around one twentieth of the area. The vast majority of these is the open and hilly plateau dominated by fields. The village of Lendsiedel , bordering the beginning of the lower reaches, lies entirely in it, the small hamlet of Eichenau at the mouth about halfway. The otherwise unsettled area lies within the Lendsiedler district marking of the small town of Kirchberg an der Jagst.

Tributaries and lakes

  • RiverIcon-SmallLake.svgFlows through at about 385  m above sea level. NHN the Röteweiher reservoir , also Lendsiedler See , at the end of the Kraftsklinge , 0.8 ha.
  • Teufelsbach , from the left and west-southwest to just under 355  m above sea level. NHN at a field lane crossing already close to Lendsiedel, 1.0 km and approx. 1.0 km². Arises at about 365  m above sea level. NHN on a dirt road in the street meadows east of Dörrmenz .

Landscape protection area

The Unterlaufklinge from the lower local border of Lendsiedel is part of the landscape protection area Mittleres Jagsttal with side valleys and adjacent areas .

history

In the forest islands Geißholz and Birkenlehle there are some burial mounds , as is often the case in the high altitude areas of the surrounding Gauland landscape occupied by the forest .
