Vipava at Uhanje (Dulanov mlin)
Where the upper Vipava leaves the flat Ajdovščina plain at Uhanje, the river narrows and the weir of Dulanov mill (also called Klemšetov mill) deepens it enough for diving. Upstream of the weir the river undercuts the left bank into a pool up to 3.5 m deep where a big Soča (marble) trout lurks, and after about half an hour the bed becomes too shallow to continue. Below the weir there is only a small 2.5 m plunge pool circled by a shoal of large, shy fish. The bed is weedy gravel with good visibility at low water.
Tiefe: 0–3.5 m
