This dive site, Bütgenbach Stausee, is situated approximately 100 meters from the dam, with a strict requirement to maintain a minimum distance of 50 meters from the dam wall. Access is convenient via a narrow path leading down a staircase directly into the water, categorizing it as a shore dive. Underwater, divers can explore a unique artificial course connected by a rope, featuring various objects such as rings and a catamaran, typically found at depths ranging from 10 to 16 meters.
As a freshwater lake, the marine life primarily consists of typical European freshwater species. While specific details are not provided, divers might encounter common fish like perch, pike, or various smaller schooling fish. Aquatic plants are likely present, providing habitat around the shallower areas and the artificial structures of the course.
The best time to visit would generally be during the warmer months for more comfortable conditions, though year-round diving is possible with appropriate cold-water gear. A key highlight is practicing navigation and buoyancy on the structured underwater course. Divers must purchase day or annual tickets in advance at the Worriken holiday park information desk. It is suitable for all levels, particularly beginners, and also offers good opportunities for freediving due to its accessible depths.
