Obrh Creek () is a losing stream that originates and terminates in the Loà ¾ Karst Field in the Municipality of Loà ¡ka Dolina. It is a watercourse in the Ljubljanica watershed. It is created by the confluence of Little Obrh Creek () and Big Obrh Creek (); the latter is fed by two tributaries: Breà ¾iÃÂek Creek and Vià ¡evek Breà ¾iÃÂek Creek (). The confluence, at which point it is simply named Obrh, lies west of the village of Pudob. In the northwest, limestone part of the karst field, Obrh Creek starts to drain into many sinkholes, and higher water flows into Golobina Cave. The stream re-emerges at the spring of the Strà ¾en River to the northwest on the southeast edge of the Cerknica Karst Field.
The name Obrh comes from the Slovene common noun obrh, referring to a powerful karst spring that usually surfaces below a cliff, creating a small deep lake that flows into a valley. The noun is originally a fused prepositional phrase, *ob vÃÂrxÃÂ 'at the summit' (i.e., at the highest point of the watercourse).
