Obrh (creek)
Obrh Creek is a short, disappearing river in southern Slovenia. It is part of the Ljubljanica watershed and begins where two streams, Mali Obrh (Little Obrh) and Veliki Obrh (Big Obrh), meet in the Loška Dolina area. Veliki Obrh is fed by Brežiček Creek and Viševski Brežiček Creek.
After their confluence, Obrh flows through the limestone of the Lož Karst Field, where much of the water drains underground into sinkholes and into the Golobina Cave, about 850 meters away. The stream then reappears at the Stržen River spring, about two kilometers to the northwest on the southeast edge of the Cerknica Karst Field.
From there, Obrh’s waters continue through a sequence of rivers to the Black Sea: Stržen → Rak → Unica → Ljubljanica → Sava → Danube → Black Sea.
Name note: Obrh comes from a Slovene word meaning a powerful karst spring that surfaces below a cliff and forms a deep spring feeding into a valley; this origin is linked to the idea of “at the summit” of a watercourse.
