Lech Dam 23, also known as Mandichosee, is an important dam on the Lech between Landsberg am Lech and Augsburg. It was put into operation in 1979 and serves both to generate energy through hydropower and as a popular local recreation area. The reservoir covers an area of around 160 hectares and is located in the municipality of Merching in the Aichach-Friedberg district.
Technical details:
• Dam: The dam consists of a gravity dam with a weir, combined with an earth dam.
• Hydroelectric power plant: The associated run-of-river power plant uses the energy of the Lech to generate electricity.
Leisure and recreation:
The Mandichosee has developed into a popular leisure paradise. Visitors can enjoy various activities here:
• Swimming: There are several beaches and lawns that invite you to relax.
• Water sports: Sailing, surfing and stand-up paddling are popular sports on the lake.
• Fishing: The lake offers good conditions for anglers.
• Hiking and cycling: There are well-developed paths around the lake that are ideal for walks and bike rides.
There is also a beach volleyball court, a playground and a kiosk with toilet facilities. A water rescue station ensures the safety of bathers.
Ecological importance:
In addition to recreational use, Lake Mandicho also plays an important role in flood protection and the ecology of the Lech. The barrage regulates the water level and protects the surrounding areas from flooding. In addition, measures have been taken to improve the ecological situation, such as the construction of fish ladders to ensure passage for migratory fish species.
Lake Mandicho thus combines technical functions with nature conservation and leisure activities and is a valuable recreational area for the people in the region.
