The Lein is a river in Baden-Wuerttemberg , which rises near Kaisersbach in the Welzheimer Wald and after a 57 km long, mainly eastward course in Abtsgmünd flows from the left into the somewhat smaller Kocher .
geography
course
From its origin at Kaisersbach -Eulenhof, the Lein flows steadily to the south and past Welzheim in the east. At Alfdorf - Haghof its course bends to the east and maintains this direction with slight fluctuations as far as Heuchlingen , from where it reaches Abtsgmünd and the Kocher in a north-easterly direction. Its catchment area is mainly on its left, because in its southern Obertal, on the right in the nearby Wieslauf and its tributaries, it has a strong competitor with a significantly deeper erosion base ; in the eastern central reaches to Heuchlingen, the Rems tributaries dig its water away so much that the watershed follows the Lein itself close to the south, often only a few hundred meters from the river itself. Only in the northeast-oriented lower reaches from Heuchlingen does it have any noteworthy right tributaries, here it shares the ridge around Dewangen with the Kocher in roughly equal parts . Its tributary system has roughly the shape of a ridge: the Lein itself lies in the south and west, while the larger tributaries strive towards it from the north.

Hydrology
Main hydrological strand
From a hydrological point of view, the Lein can be regarded as the main source load of the Kocher system, as it is more than twice as long at the mouth as this (57 km versus 25 km), the upper reaches of which is also exceeded in the catchment area (250 km² to 152 km²) and also has a little more water than this - despite its powerful karst springs, which also feed from areas beyond its superficial watersheds.
Flow direction
The flow direction of the flax is noticeable; it moves away from the Neckar, into which its water ultimately reaches via the Kocher, and in Abtsgmünd its valley meets that of the Kocher almost in the opposite direction, which flows there towards the west-northwest of the Neckar . The reason for this is that the course of the river Lein was created at a time when the area was still draining to the southeast towards the original Danube and the Black Sea . The same applies to the neighboring rivers "Spiegelberger" Lauter , Bibers , "Fichtenberger" Rot and the Blinde Rot, which flows into the Kocher almost in the opposite direction from a little below Abtsgmünd . The current runoff over the Kocher, Neckar and Rhine to the North Sea only arose when the Upper Rhine Rifts began to sink from the Eocene and, as a result, the deep erosion in the surrounding river system of the Rhine intensified. The main European watershed gradually shifted to the southeast in favor of the Rhine via numerous taps from the Danube tributaries .
Flood protection and retention basins
Nowadays the Lein and their northern tributaries feed numerous smaller reservoirs, many of which were created for flood protection and which, as bathing lakes (e.g. the Aichstrut reservoir), also serve for local recreation. Others are old mill lakes, because many water mills used to run along the Lein and the larger tributaries.
After recurring floods along the Lein, one in March 1956 finally gave the impetus to found the water association Kocher-Lein by the neighboring communities in 1957. For flood protection, the new association built eleven storage and retention basins between 1957 and 1982, which it still operates today . Five of these are in the Rems-Murr district, six in the Ostalb district. They are constantly dammed up into small lakes. Most of them are developed for local recreation, some are designated as bathing lakes. The eleven artificial lakes can hold back up to 14 million m³ , they are between 390 m above sea level. NHN and 500 m. ü. NHN. and its total catchment area extends over approximately 250 km². Between 1990 and 2000, as part of a renovation program, 28.5 million euros were spent, partly in facilities for remote data transmission and remote control, so that since 1997 all eleven pools can be centrally controlled and monitored.

history
In its upper reaches the Lein followed a political border for a strong century in ancient times. Between its source and the Haghof south of Welzheim, the Upper Germanic-Raetian Limes , a UNESCO World Heritage Site , ran a few hundred meters to the west parallel to it , the fortified borderline of the Roman Empire against the barbaric Germania .
