Lake Slivnica, lake in Slovenia

Lake Slivnica is an artificial reservoir by the village of Gorica pri Slivnici, about 5 km south of Šentjur. It was formed in 1976 by dams on the Dobrinski potok and Ločnica streams. The lake is 5 km long, 0.5 km wide, up to 14 m deep and covers 8.4 ha. The Ločnica flows in and the Voglajna flows out.

The lake was created in 1976 behind a dam built across two streams to supply water for a nearby steel plant in Štore. After the factory stopped needing the water, the reservoir remained and became managed for flood control and public recreation.

Locals around Lake Slivnica built the country's first road underpasses for frogs, and during migration season they set up barriers along the roads to prevent large numbers from being run over. The lake itself is used for fishing and tourism, and the eastern shore holds an ichthyological and ornithological reserve.

The area is easy to reach by car from Šentjur or Gorica, or by bus from nearby towns. A dedicated bicycle path runs around the water, and walking trails are freely accessible for visitors throughout the day.

Locals built Slovenia's first road underpasses for frogs here, and during migration season they also set up barriers along the roads to stop large numbers of the animals being run over. The lake and its shores hold over 100 bird species and 32 fish species, along with lampreys, crabs and shellfish.
