The Lottenbach is a tributary of the Ruhr. It characterizes the green corridor Lottental in the southwest of Bochum in the districts of Stiepel and Querenburg .



The valley is traversed in a west-east direction by the first Stiepeler Bach , then Lottenbach , which flows into the Ruhr or the Oelbach at a length of about 3.5 km at Lake Kemnader . Its tributaries are Vosskuhlbach and Kalwesbach .


nature and environment

The water quality class varies between II and III.

The valley is hardly populated and is characterized by pastures and mixed oak and beech forests.

The Lottental is known for its amphibians , including water frogs , common toads , pond newts , mountain newts and fire salamanders . Bird species include tawny owl , great spotted woodpecker , green woodpecker and small woodpecker .

The planned expansion of the Ruhr University in the area of ​​the G buildings is intended to restrict the living space.

Settlement and industrial history in the vicinity of the Ruhr University

It is believed that the name goes back to Lotte ( Westphalian for mill ). There were at least two mills, one of them at the level of the Grünendiek farmstead and another until 1918 at the level of the Klosterbusch colliery . Another assumption is that the valley was named after the Lutten, which the Julius Philipp colliery relocated in the meadow valleys of the Stiepeler Bach in 1875 in order to reduce the water inflow in the underground structures.

Which passes through the valley road goes to the Lotte Talbahn back, a former horse-drawn railway for the transport of the valley from the mines subsidized coal to the Ruhr. This early railway line was laid out around 1830 and ran on wooden rails . In the upper part of the valley, a former retaining wall of the route was cleared a few years ago during a storm ; the archaeological findings were secured as a ground monument and are freely accessible today.

About 1 km away from the confluence with the Ruhr there are traces of coal mining, which ended here in 1959 with the closure of the Emmaglück small mine at the Julius Philipp Erbstollen .

In order to gain more pasture and settlement areas, the stream was put in a concrete channel and even completely piped in the lower course. Employees of the Biological Station Eastern Ruhr Area in Herne and the Geographical Institute of the Ruhr University Bochum determined the old stream in 1997 through on-site measurements and from land register plans from the 19th century . On November 7, 1997, around 200 pupils from the Schillerschule and Graf-Engelbert-Schule grammar schools began to renature the upper stream with a spade , shovel and hoe over a distance of at least 200 m. Typical riparian trees ( alders and willows ) were then planted.

The brook flows through a large pond and is part of the pond complex of the Botanical Garden of the Ruhr University Bochum . The valley is known in Bochum for its rich amphibian fauna . During the period of Krötenwanderung the only road is blocked every year to toads and other endangered species through April 15 for the egg-laying to provide protection during the peak traveling period from 1 March. Local nature conservation associations have been involved here since 1980.

The large quarry in Lottental, the largest geological outcrop in Bochum, the Stockumer Sattel, in which material was extracted for backfilling the mined seams of the Klosterbusch colliery, is striking . Botanical test areas are located behind the former wash house. The largest contiguous forest in Bochum, the Kalwes, is also located here .

There are other facilities of the Ruhr University Bochum in the Lottental . The teaching workshop for experimental archeology of the Faculty of History is housed in the rooms of the former Klosterbusch colliery . Stone processing, bronze casting and other techniques are tested and researched here. The experimental halls of the Faculty of Civil Engineering are located in the same building .

The "Center for Interdisciplinary Regional Research" (ZEFIR) is located in house Lottental 38. It is a central scientific institution of the Ruhr University Bochum. This is where the "Information and Qualification Center for Municipalities" in North Rhine-Westphalia (IQZ) is located.
