The Große Aue is a left tributary of the Böhme in the Heidekreis district in Lower Saxony . Like the Böhme, which runs parallel to the south to the west, the brook drains the southwestern edge of the Hohe Heide between Soltau and Bispingen . Its headwaters are the Great Moor near Grasengrund north of Deimern . After 13 kilometers the Große Aue joins the Böhme south of Tetendorf .

Course and natural space

The valley of the Große Aue is much wider and more elongated than the valley of the Böhme, which is about twice as large at the mouth. The brook follows one of the meltwater channels that emanated from the northeastern inland ice of the penultimate glacial period ( Wartha stage of the Saale glacial period ) and subdivide the terminal moraine of the Hohe Heide. The Heidbach flowing in from the northeast also follows such an, albeit narrower, meltwater channel, possibly also the Harber Mühlenbach , which runs parallel to the south . In nearly planar areas of the former meltwater channel (have after the last ice age Weichselkaltzeit ) fens formed partly to bogs have developed. The creation of the Great Moor in the source area of ​​the Great Aue began around 8500 BC. With first peat formations , around 5000 years BC. Chr. Began extensive bog. At the same time, further moors accompanying the water body developed . The Great Moor belongs to the south-eastern part of the Lüneburg Heath nature reserve . The Ehbläcksmoor that follows down the valley is also under nature protection. The landscape protection areas Oeninger Bruch and Upper Böhmetal follow further south .

Flora and fauna

There are numerous endangered animal and plant species in the area of ​​the Große Aue. Due to the relatively good water quality, endangered fish species such as the minnow , the Mühlenkoppe , the brook lamprey and the brook trout , as well as endangered aquatic insects, live here . The polecat and various bat species have also been observed here. Numerous, sometimes rare, plant species can be found here, including the marsh calla , the water feather , the marsh sword lily and the gale bush .

historical development

Archaeological cultures in the catchment area of ​​the Große Aue have been proven as early as the Paleolithic Age . In the area of ​​today's Great Moor , numerous devices were found, mainly from the Hamburg culture , but also from the Ahrensburg culture . Barrows from the Bronze Age are not far from the stream valleys at Deimern and Hambostel .

Human settlement and management, which was more aimed at the floodplains than the moors, replaced the alder forests that were once widespread here .

The river network of the Große Aue includes three historic watermill locations in Hambostel , Weiher and Harber . Parts of the mill in Hambostel and the reservoir oak in Weiher and Harber have been preserved to this day. The Große Aue was also used as a fishing water, for example through the Spiekerhof pond .

From the 19th century onwards , the creation of Rieselwiesen entailed extensive interventions in the structure of the water : Sections of the stream were straightened and deepened, weirs were set up and ditch systems were created. The economic use of the Great Moor in the 20th century led to an extension of the upper reaches of the stream, then known as the Aue , by almost two kilometers.

Below the Ehbläcksmoor, the Große Aue has been accompanied for several decades by the facilities of the Heidepark Soltau amusement park .
