Abstract: The hydropower plant "Višegrad" is located on the Drina River upstream of Višegrad. Many seepage occurrences have been observed since the construction. Over time, the measured quantities of seepage water under the dam body increased significantly: from 1.4 m3/s (1990) to 14.68 m3/s (2012). Investigations were implemented during 2008-2009 period to define the directions of groundwater movement. Repair design was developed based on subject investigations. Repair was implemented with continuous monitoring of the effects of installation, on a complex monitoring system, and real-time data processing in the mathematical model results of which were then used to adjust and direct the works. The works were carried out in 2 phases. The inert materials were installed in the first phase, while the consolidation was carried out in the second phase. The total water losses from the reservoir at the end of the repair works were reduced to 3.74 m3/s. This paper presents the investigation activities carried out before and during the repair works, which facilitated the big success of works on the remediation of the HPP "Višegrad" dam.
