The Hengsteysee is located near Hagen below the confluence of the Lenne and the Ruhr. At the time of its commissioning, the mixing of the acidic and iron-containing Lenne water with the alkaline Ruhr water resulted in increased sludge precipitation and thus an intensive cleaning effect. Today, it is primarily the Ruhrverband's ultra-modern sewage treatment plants that ensure the water quality, but the reservoirs are still essential as a fine purification stage for discharged rainwater and as a bedload trap for river gravel from the Lenne. In addition, the Hengsteysee has been used since it was commissioned as a lower basin for the Herdecke pumped storage power plant (Koepchenwerk) built by RWE. Due to the pumped storage operation, the water level in the Hengsteysee can fluctuate by up to 70 centimeters. In 1988/89, the sediment deposited up to that point, amounting to around 400,000 cubic meters, was removed from the Hengsteysee using a dredging process. s.a. Ruhrverband

A very beautiful part of the Ruhr Valley Cycle Path and the Lenne Route. Hengsteysee and Harkortsee belong together like brother and sister. Both are former bodies of water used by heavy industry that have been converted into well-used recreational waters with good water quality, flora and fauna. There are plenty of places to stop for a break around Hengsteysee and Karkortsee. Note: In many places there are designated cycle facilities (sign 237) and designated pedestrian paths (sign 239). For those walking or running, whether with children and dogs or alone, please use the paths specially set up for you and do not walk on the cycle lanes. Just as it is our duty to use the cycle lanes, it is our duty for pedestrians to use the footpath. Below the serpentine road coming from the B54 is a biker meeting point Hohensyburg 🤠 👍 If you see an "E-Biker" 🤜 there, then the steam on the gas tap

If you drive during the week, then it's ok. At the weekend, like many other tours, it is just too crowded. The Ruhr Valley Cycle Path is particularly popular

The Syberg with the Hohensyburg castle ruins, the Kaiser Wilhelm monument and the Vincket Tower is a popular destination in the south of Dortmund.

Historical monument, large square all around, great view of the Hengsteysee, Ruhr and Lenne, Hagen ... There is a flatter and a steep ascent and descent, the latter is more interesting because it contains the old mining route.
