Hennesee

Hennesee is a reservoir located in the Sauerland region of North Rhine-Westphalia, Germany. It was created by the damming of the Hennesee river, a tributary of the Ruhr. The primary purpose of the Hennesee is flood control and water supply for the surrounding areas. Construction of the dam began in 1947 and was completed in 1952. The reservoir has a significant capacity and plays a role in the water management system of the Ruhrverband, the organization responsible for managing water resources in the Ruhr river basin.

The Hennesee is also a popular recreational area. Its shores are developed with various amenities catering to tourists and locals. Activities such as swimming, sailing, windsurfing, and fishing are commonly enjoyed on and around the lake. Several hiking and cycling trails surround the Hennesee, offering scenic views of the landscape. A notable feature near the reservoir is the Hennesee Tower, a observation tower providing panoramic vistas of the lake and the Sauerland hills. The area is a significant contributor to local tourism, drawing visitors throughout the year, especially during the warmer months. The water quality of the Hennesee is regularly monitored to ensure its suitability for both its functional purposes and recreational use.
