Jama Poltarica (Krka tributary spring cave)
Poltarica is the first right-bank tributary of the Krka, 400 m from the Krka spring; members of the Novo mesto caving club dug into the cave in 2003 and found large halls with an underground river. Divers swam the 15 m long, 2.5 m deep inflow sump into a 100 m water hall and later found a continuation at 13 m depth that added 70 m before narrowing. Other dives explored outflow sumps 12 m and 5 m deep. The Blatni rov canyon fills with torrential water in high flow.
Tiefe: 0–13 m
