Considering the burst of the dam as a potential catastrophe, since the tailings would flood Gornji Milanovac, the dam has been upgraded in time. It is fit to survive the earthquake of the 9.0 magnitude on Richter scale. In 2013 devices for early notification in case of a quake were installed and are directly connected to the state seismology institute. During the major 2014 Southeast Europe floods, the lake accumulated additional of water, which would otherwise flood the town. The flood wave from the slopes of the Rudnik was damped and effectively prolonged over five days instead of sweeping all at once. The treating apparatus allows for the clean water to be let through the dam into the Despotovica river. Several projects are being developed. In 2018 a new system for evacuation of the water in case of emergency will be installed, while by 2023 a new plant will be built which will further treat the wastewaters.
