Sylvenstein Damis an earthenembankment damin theIsarvalley, in the alpine part ofUpper Bavaria,Germany which impounds the Sylvenstein Reservoir (German:Sylvensteinspeicher).
In the 1920s, severalhydropowerplants were built in thetributaryof the upper Isar River such as ones at theAchenseeandLake Walchen Power Plant.Therefore, the river ran nearly dry during the dry season, and the low water flow affected the town ofBad Tölz.A reservoir was established to ensure a minimum water level in the river. During the dry season, avolumetric flowof 4 cubic metres per second is released to prevent the Isar from running dry. Additionally, the reservoir providesflood controlfor the Isar River betweenBad Tölzand Munich.
The dam is 44 metres (144 ft) high and 180 metres (590 ft) long. It was built between 1954 and 1959. Since 1959, the water has also been used to operate a hydropower plant of 3.2 MW. The plant was upgraded in 2000 with new turbines to generate 3.8 MW.
During the2005 European floods,the reservoir's maximum capacity was reached. Consequently, excess water was released into the Isar River. Without the dam construction, the flooding in 2005 would have been even more severe than it actually was.
A small village namedFallwas flooded in 1959. TheFaller-Klamm-Brückeconnects road traffic to the North (Bundesstraße 307).
