Edersee

Edersee is a reservoir in the state of Hesse, Germany, formed by the Eder Dam on the Eder River. It lies in the district of Waldeck-Frankenberg, near the town of Waldeck and the municipality of Edertal, and it is closely associated with the Kellerwald-Edersee National Park. The reservoir serves multiple roles, including flood control, hydroelectric power generation, water regulation, and recreation, and it is one of Germany’s largest reservoirs by volume.

Construction of the dam began in the early 20th century and was completed in 1914. The creation of the lake required the relocation of several villages and farmland that stood in the valley. Since then the Edersee has become a major recreational area, attracting visitors for boating, swimming, fishing, and hiking.

Geography and features: The lake extends along the Eder valley for a considerable distance, forming a long, winding body of water with a substantial shoreline. It covers roughly 11 square kilometers and reaches depths of several tens of meters at its deepest points. The dam itself is a substantial concrete structure that creates a reservoir of wide geographic scale.

Surroundings and protected area: Much of the shoreline lies within the Kellerwald-Edersee National Park, a UNESCO World Heritage Site known for its beech forests and natural landscapes. The area supports diverse wildlife and a network of hiking trails, viewpoints, and visitor facilities.

Recreation and access: In addition to water sports, the Edersee hosts marinas, boat rental, beaches, and seasonal events. It remains a focal point of tourism in northern Hesse, closely linked to nearby towns and to the national park.
