On the German base map, however, another source stream bears the name Nahmerbach, which is located in the village of Sonnenscheid at 461  m above sea level. NN rises and flows into the former after 1.5 km.

The Nahmerbach flows predominantly in a north-northwest direction as a border brook of the communities Nachrodt-Wiblingwerde and Schalksmühle , flows through Hagen and then flows into Hagen-Hohenlimburg at an altitude of 117  m above sea level. NN from the left into the Lenne. On its 11.2 km long path, the stream runs through a height difference of 329 m, which corresponds to a mean bed gradient of 29.4 ‰.

At the Nahmerbach there are numerous former water mills, hammer mills and, in the lower reaches, other industrial plants of the Hohenlimburg cold rolling industry. The buildings that are significant in terms of industrial history include the former castle brewery, the Lennewehr, the former roller, the Giebel rolling mill , the administration building of a former copper hammer, a former factory owner's house, the Selbach hammer , the Brenscheider grain mill and the Brenscheider oil mill .

Cold rolling industry in the Nahmertal

In the 17th century, an important textile industry established itself in the Wupper valley ; Their so-called Barmer articles - braids , ribbons , threads , fabrics, clothing , etc. - were exported all over the world. But not only the raw materials had to be imported to the Wupper , also the necessary machines such as looms and spinning machines . From the beginning of the 19th century, metal wire was an essential part of the machines .

In order to meet the growing demand for wire for the machines of the Wuppertal textile industry, wire drawing shops settled in Nahmerbach and from 1850 onwards, with the advent of crinoline and corset fashion , all cold rolling plants were established . Large quantities of high-quality steel strips and special wires were produced which, in addition to the textile industry, were also used for the manufacture of bicycles and typewriters .

In the lower Nahmerbachtal to Hohenlimburg there was one of the highest densities of this branch of industry in the region towards the end of the 19th century, the Hohenlimburg small railway running parallel to the brook ensured the connection to the railway network. A few companies still produce here today despite the massive structural change . This includes the company CD Wälzholz in the company , in front of whose works a locomotive of the Hohenlimburg small railway is on display. The company JP Hüseken & Comp in Obernahmer and the Nimmertal owned a factory owner's house from the years before 1810, which is now used as a residential building. Architecturally noteworthy is the three-part facade of the Giebel company, which was built in 1925 . These industrial monuments are part of the Route of Industrial Culture .

Koenig Lake

Remains of the dam on the former Koenig Lake

At the Lame Hasen there was a reservoir , the so-called Koenig-See , which is named after the industrialist Heinrich Koenig. The pond was created to store the cooling water for the WURAG company . In the summer months, the lake used to be a popular destination. In 1995 the pond was drained when the Krupp plant closed.

In the upper reaches of the Nahmerbach there are now a few ponds that are used for trout breeding.
