About Bilećko Lake#

Bilećko Lake (Bilećko jezero) is an artificial reservoir near the town of Bileća in southeastern Bosnia and Herzegovina. It was created by damming the Trebišnjica river and serves hydroelectric and water-management purposes.

The lake has an irregular shoreline with bays and wooded slopes and is used locally for fishing, boating and lakeside recreation. Roads and viewpoints around the town provide access to scenic stretches of the reservoir.

The reservoir was formed in the mid-20th century when a dam was constructed on the Trebišnjica river as part of regional hydroelectric and irrigation works. The creation of the lake changed the local landscape and economy by submerging river valleys and extending water storage capacity.
