Iška

The Iška is a river of central Slovenia. Part of the river valley—the Iška Gorge or Iška Canyon (Iški vintgar)—separates Lower Carniola from Inner Carniola. The river is 31 km long. After flowing past Strahomer, the river follows an almost straight line and joins the Ljubljanica River, and therefore belongs to the Sava and Black Sea basins.

The part of the river between Iška Vas and Strahomer disappeared underground during the 2010 Slovenia floods, on the night of 20 September 2010.
