Idrija river pools at Podravno
The Idrija (not to be confused with the Idrijca) forms the Slovenia–Italy border in its upper course. Below Kambreško, in one of the most remote corners of Slovenia near the dying villages of Rog, Kosi and Podravno, it has a few larger pools known to few locals, which is why they are so full of life. The round pool below a waterfall is about 15 m wide and 4 m deep, and an elongated pool a few minutes downstream is about 20 m long and 3 m deep. Trout rest in the deepest water, chub and barbel hide under rocks, and crayfish boldly stand their ground.
depth: 0–4 m
