From mid-2007 to early 2009, the dam was completely renovated. Among other things, cracks and joints in the masonry had to be repaired, the roadway and railings had to be renewed and the arches of the flood relief had to be repaired. For the duration of the work, the top of the wall, the parking lot at the dam and the toilet facilities were closed to visitors. The renovation work, particularly on the railings and arches, has permanently changed the appearance of the dam.[8] In the years 2020 to 2022, the wall on the water side, which is stressed by the fluctuating water level, was renovated in three construction phases. In order to clear a four-meter-wide strip below the crown for work, the Lister Dam had to be lowered by 4.50 meters at a time. In this area, all joints could be chiseled out and loose stones could be anchored or replaced. After repointing and sandblasting, the character of the quarry stone masonry can be clearly seen again. A total of 30 kilometers of wall joints on both sides of the wall were treated in this way, which strengthened the Lister dam for decades to come.

The planning for the construction of the Listertalsperre goes back to the Ruhrtalsperreverein (RTV), founded in 1899, which had set itself the task of supplying water to the rapidly growing Ruhr area. Government master builder Ernst Link and construction director of the RTV had assessed the Listertal as particularly suitable when looking for other suitable locations for the construction of a dam. His report from 1905 was soon followed by the founding of the Lister Dam Cooperative, which tackled the construction of the dam with the financial support of the RTV. The ground-breaking ceremony took place on September 13, 1909, and almost three years later, on July 5, 1913, the ceremonial inauguration took place by director Kluge from Braunschweig, the head of the cooperative

The Sorpesee has the third largest dam wall of all Sauerland reservoirs. From here you have a great view over the lake. There are many benches for long breaks. The cycle path leads over the wall around the reservoir and is in excellent condition. Sometimes it is shared by skaters and hikers. Partly the route leads through very beautiful forest sections.

What else can one say about the Biggesee, it's simply a beautiful area, ideal for cyclists, of course, as it's easily accessible all around
