In order to comply with the latest German technical standards and safety regulations, the Ennepetal Dam with a 96-year history is being retrofitted. Drainage systems and monitoring corridors were constructed using tunnel boring machines and were completed in August 1998. The renewal of the bottom of the scupper and the portal tower has also recently begun.
