Trebišnjica wellsprings group

Trebišnjica wellspring-group is a system of two geographically and hydrologically distinct principal groupings of strong karstic springs, Trebišnjica and Čeplica, which together constitute source of the Trebišnjica river. Wellsprings are located just below town of Bileća in Bosnia and Herzegovina. The entire area where springs are situated is submerged under Bilećko Lake since 1968, with construction of Trebinje-1 Hydroelectric Power Station and its dam at Grnčarevo village.[3]

Springs

The Trebišnjica river emerges under the karstic plateau on which town of Bileća sits. There are two main spring-groups, first in immediate proximity of town itself, and second some 3 kilometers downstream at Ćeplica village.

Trebišnjica spring-group

The Trebišnjica spring-group below Bileća, at 325 m (1,066 ft) a.s.l.,[1] is composed of three major wellspring outlets, "Dejanova Pećina", "Vrelo Oko", and "Nikšičko Vrelo".

Čepelica spring-group

Another submerged springs are Čepelica river spring-group ("Čeplica spring-group"), located at Ćeplica village, 3.25 kilometres (2.02 mi) further down the stream from first group, at 324 m (1,063 ft) a.s.l.[1] The Čepelica river itself was less than 2 kilometres (1.2 mi) long seasonal river, and flowed through valley of "Luke" (literally transl. Bay, Haven, Harbour; figuratively transl. glade(s), meadow(s)) before it meet Trebišnjica at "Mistialj" confluence. The Čepelica spring-group consists of two main karst hydrological features, Wellspring Čepo (Vrelo "Čepo") with three main outlets, and group of smaller estavelles (sinkholes) and springs on the left-bank side of the Čeplica river streambed.
