The gravity concrete dam is 136m high with a crest length of 1300m. Over 300 Huggenberger sensors with Carlson technology were installed around 1994. In 2021, we carried out a functional test of the existing instruments then we upgraded the system from manual to semi-automatic by installing Hek-Mux Boxes.
In 2022, after the rehabilitation of the existing shafts we installed some new 76m long plumblines consisting of direct pendulums. We also supplied automatic Huggenberger Telelot VDD2v4 systems for measuring the horizontal deformations of the dam.
