Vrutak, artificial reservoir in Bosnia and Herzegovina

Vrutak is a small reservoir in Bosnia and Herzegovina situated near the village of Hutovo in flat countryside. The water is calm and clear, bordered by green grassy banks and surrounded by fields and patches of woodland.

Lake Vrutak was created in 1979 by the construction of the Čapljina Hydroelectric Power Plant, for which it serves as the upper compensation basin. It is the last and smallest of three artificial reservoirs in the Trebišnjica hydropower system, after Bilećko Lake and Trebinjsko Lake. Water reaches it from the Trebišnjica via a 65 km concrete-lined canal.

Its name, "vrutak", is the local word for a karst spring, although the basin itself is fed by the 65 km concrete canal from the Trebišnjica rather than by a spring.

The reservoir lies at the western end of Popovo Polje by Hutovo, reached by local roads from the Čapljina and Stolac direction. Water arrives via a 65 km concrete channel from the Trebišnjica, and a tunnel 8.1 km long and 8 m in diameter carries it to the Čapljina plant. The banks are working infrastructure, not a landscaped park, so there are no marked trails or facilities; walking is on uneven ground.
