Since August 2022, the company HTB Baugesellschaft m.b.H. has been renovating the paths to the dam stages, individual basins, dam walls, etc. Due to the inaccessibility, many of the required construction materials and machines had to be brought to the site by helicopter. We would like to thank all the companies involved for the smooth operation. Especially in times of energy shortage, maximizing our own power supply is our highest interest.
