The Novat tailings dam is located in the upper basin of the Novat stream, which flows through the Ursul stream into the Vaser River. Mention should be made that the basins of the Vaser River and Viseu are protected areas, which do not allow any discharges downstream and require the repumping of the cleared waters back to the flotation of Baia Borsa mine. Overtopping of the main and downstream dams, with their partial destruction, occurred on 10 March 2000 as a result of the torrential rains falling across the entire surface of the Novat stream receiving basin. Before the accident occurred, deposits from the tailings dam reached 802.0 maSL, with the clear water mirror at 804.50 maSL. The paper deals with the safety of Novat tailings dam after the accident in March 2000.
