Forggensee, Artificial lake in Ostallgäu, Germany
Forggensee is an artificial lake in Ostallgäu, Germany, covering more than 15 square kilometers. The body of water lies south of Füssen near the Alps and ranks among the largest reservoirs in the country.
The reservoir was created in 1954 through the construction of a dam on the Lech River. The work led to the resettlement of more than 250 people from the valley and the flooding of old settlement areas.
The name comes from a hamlet that disappeared beneath the water. Today the reservoir supports power generation and flood control while remaining open for leisure activities.
The water level changes considerably, especially in winter when it drops by several meters. Best access is through shore roads in the area, where parking and boat launch points are available.
When the level drops in winter, old Roman traces and remains of Stone Age hunting camps reappear. These finds show that the valley was inhabited thousands of years ago.
