The waterfall is supplied by a karst spring under an almost vertical limestone wall. Because of its karst nature, the spring has a relatively large discharge due to its underground drainage in the mountains of Kanin. During the driest periods, water flux is around , and reaches up to after extensive rains. The stream (also called Boka) flows for about over a rocky shelf before falling over the rocks as a spectacular waterfall. This happens in two not so clearly separated stages, of which the upper one has a height of , and the lower one . The width of the two stages is around .
