The masonry dam of the Urft reservoir was built from 1900 to 1904. An examination of the dam's stability according to today's standards gave reason to drive inspection galleries in the dam, to carry out in-situ tests in order to determine the characteristics of dam and underlying rock and to install an extensive measuring programme. Based on the test and monitoring results, a three-dimensional model was elaborated and calibrated, which made it possible to proof the dam's stability under consideration of the three-dimensional load-carrying action of the dam.
