Idrijca at Slap ob Idrijci
At Slap ob Idrijci the Idrijca squeezes through a narrow gorge in hard rock, dammed long ago for a mill and now also for a small hydropower plant. Below the weir the gorge is more than 5 m deep and opens past the bridge into a wide pool, where a large shoal usually circles while big fish lurk singly in the gorge; there is also a small underwater cave under the weir. A second, separate dive is possible in the calm stretch above the weir, over 3.5 m deep for some 500 m. In summer the water reaches 22 °C, and the sheet rates it ideal for beginners, training and night dives.
depth: 0–5 m
