The reservoir has a total capacity of approximately 171.7 million cubic meters of water.
Construction of the main dam wall, completed in 1965, required the resettlement of several villages in the valley.
The reservoir is managed by the Ruhrverband, a regional water management association.
The Biggesee system consists of two connected basins: the Biggesee and the smaller Listersee.
The dam wall at the Bigge end reaches a height of 52 meters above the valley floor.
Diving is permitted at the designated 'Taucherbucht' (Diver's Bay) near the dam wall.
Biggesee is one of the largest reservoirs in Germany, serving as a primary water management system and recreational hub in the Sauerland region. The reservoir was created by damming the Bigge and Lister rivers, resulting in a complex, multi-armed water body. It acts as a flood control mechanism for the Ruhr river basin and supplies drinking water to the surrounding region. The area features a dedicated fleet of passenger ships that navigate between designated piers. The shoreline is heavily utilized for swimming, sailing, and windsurfing. A network of cycling and hiking paths circles the reservoir, including a trail that crosses the prominent Biggetalsperre dam wall. The Bigge power plant remains active, utilizing the water pressure for hydroelectric energy generation.
The pedestrian walkway on top of the Biggetalsperre dam wall provides an unobstructed view of the water and surrounding forested hills.
Use the designated parking areas near the dam wall for immediate access to panoramic views.
Rent a bicycle to navigate the extensive paved perimeter paths, which are often faster than walking between viewpoints.
Check the ferry operating calendar in advance, as schedules are seasonal and weather-dependent.
Attempting to swim in areas outside the marked 'Badestellen' (official bathing spots) due to hidden underwater currents and depth changes.
Passenger ferry services operate strictly from spring through early autumn; trail access is open year-round.
Maintain noise levels near residential camping sites and respect designated swimming zones.
