A really beautiful corner there at the Möhnesee. Lots of space for leisure activities, whether hiking, biking or water sports. Everyone can be happy there. And if not, there are enough restaurants and cafés around the lake. 😜😁

The Möhnesee is one of the oldest dams in Germany. The 1908-1913 quarry stone barrier wall is a monument and the main attraction of the Möhnesee. The dam wall is 650 meters long and 30 meters at its highest point. The southern half of the Möhnesee is completely surrounded by the Arnsberg Forest Nature Park. The varied and extensive forest area is ideal for relaxing walks and long hikes. The circular route around the lake is great, you should plan a tour during the week, it's just too crowded at the weekend.

Calculations of the future demand for drinking and process water for the growing Ruhr area in 1904 had shown that three times the amount would be required for the existing dams in the Ruhr river system with a storage volume of 32.4 million m³, namely around 100 million m³ storage space . By 1925, it was even estimated that it would grow to almost 200 million m³. Therefore, on November 28, 1904, the general meeting of the Ruhr Dam Association decided to change the statutes to build their own dams. On May 22, 1905, the plan to build a large dam in the Möhne valley was discussed for the first time. The Möhnetalsperre was then built between 1908 and 1912[1] according to plans by the government master builder Ernst Link and a design by the Cologne architect Franz Brantzky for the dam wall at a cost of 23.5 million marks and on July 12, 1913[1] inaugurated by the Ruhr Dam Association. In the year of its inauguration, the dam was the largest dam in Europe. The former place Kettlersteich sank completely in the water. Most of the village of Delecke (Alt-Delecke) was also flooded. 140 farmsteads with 700 people had to give way to the lake.
