Feeding ducks and geese according to §55 of the Administrative Offenses Act and punished with a fine of 30 euros. This is not to annoy you. It serves to protect the animals, the cleanliness of bodies of water and bank areas and to avoid rats from leftover food lying around.

The lake is fed by the Harpener Bach, which flows through the lake from north to south and drains it into the Ruhr via the Oelbach. In the Middle Ages, two mill ponds were created as precursors to the lake at the mill of the Schulte-Suntum farm. With the construction of the Dorothea-Erbstollen at the Vollmond colliery, contamination with mine water began in the 18th century. In order to clarify the mine water, settling ponds were created. One of these settling ponds was created southwest of the Schulte-Suntum farm. While the main part of the water flowed directly into the settling pond, there was a ditch on the eastern side as a bypass that met the stream again below the pond outlet. When the Robert Müser colliery closed in 1968, the tailings pond became unnecessary. In 1976, the facility was expanded into an integral part of a local recreation area through excavation and bank and lake bottom reinforcement. https://www.bochum-tourismus.de/bochum-entdecken/parks-und-gaerten/uemminger-see.html#c10307

The Ümminger See in Bochum-Langendreer is a popular local recreation area for young and old, with a great playground and a roller skating rink. The lake is not only a popular destination for families, walkers and athletes can also find relaxation and sporting activities here. It can be walked around within two kilometers - a great distance for regular running training. https://www.bochum-tourismus.de/bochum-entdecken/parks-und-gaerten/uemminger-see.html#c10294

The Ruhr Viaduct in Herdecke spans the valley with a length of 313 m and 12 semi-circular arches, each with a span of 20 m.

Always good for a short walk, e.g. after eating in one of the Rondorf restaurants.

On July 30, 1895, the city council decided to build a waterworks and the associated dam. Professor Otto Intze from the Technical University of Aachen was commissioned with the planning and subsequent implementation. His investigations showed that the most favorable area for a dam was the Saalbach valley with its wealth of sources. At the meeting of the city council on April 14, 1897, Intze's proposals were accepted and the construction of the dam was decided. Almost a year later, the necessary land could be acquired and construction of the dam began. A quarry stone wall was erected, which was built according to the "Intze principle". This principle consisted of creating a wedge-shaped, compacted earthfill on the water side at the foot of the wall, which reached just half the height of the wall. In this way the pressure of the water on the wall could be reduced quite considerably, which enabled a lighter construction method Pump-operated pumping station and on the upper Kurfürstenstrasse, the highest point in Ronsdorf, the water tower. From here the water was fed into the Ronsdorf supply network. The dam was inaugurated on November 11, 1899. It had a storage height of around 19 meters and a capacity of 300,000 cubic meters.

The houses on the edge above are called Gibraltar

In a few places, the view of Lake Kemnader is preferable to the lower-lying footpath. Especially at special festivals on Lake Kemnader. Due to the rest of the path, which is quite poor, the foot and skate path is preferable when there is little traffic.
