However, after WWII and, especially, during the "Golden 70's", thanks to the numerous industrial plants built within the town, Lebane grew substantially and its population increased more than fivefold. The fastest pace of growth was in the period from 1977 to 1985, thanks to an unfortunate event – in 1976 Lebane was hit by a catastrophic flood. Then unregulated river Jablanica, swollen after a long rainy period, broke on June 6, spilled out of its banks and caused enormous material damage Lebane. Flood toll was paid and human victims (killed two people).
