N2 - The Sylvenstein dam with a height of 41 m was constructed in southern Germany 1954 to 1959. The dam is founded on highly permeable alluvial deposits with a thickness up to 100 m, that were grouted by a grout curtain. For the dam core bentonite-improved sandy gravel was used. After 10 years of operation permeability increased in some zones, which were grouted 1972. Further observation indicated recent irregularities in the core. The field investigation results indicate, that the reduction of water pressure drop in the core should be caused by aging of the material. The reconstruction measures are reported.
