About this water

Short karst spring river near Split — one of the key remaining habitats of the endemic softmouth trout under significant urban and environmental pressure. Spring-fed and thermally stable. WFD ecological status is 'Poor', reflecting the challenges facing this short urban-fringe river. Very limited fishing access due to the conservation status of the endemic softmouth; scientific and conservation interest is high, but recreational value is tightly constrained.
