Jablaničko Lake (Bosnian: Jablaničko jezero) is a large artificially formed lake on the Neretva river, right below Konjic where the Neretva briefly expands into a wide valley. The river provided lot of fertile, agricultural land there, before the lake flooded most of it. The lake was created in 1953 after construction of a large gravitational hydroelectric dam near Jablanica in central Bosnia and Herzegovina.

The lake has an irregular elongated shape. Its width varies along its length. The lake is a popular vacation destination in Bosnia and Herzegovina. Swimming, boating and especially fishing are popular activities on the lake. Many weekend cottages have been built along the shores of the lake. There are 13 types of fish in the lake's ecosystem.

But this, in fact, is not an advantage as the lake suffered from poor management of water and fisheries. Without any scientific and management plans or research, local fisheries and angling management introduced alien, non-indigenous or non-native species, either deliberately or accidentally, which did more harm and damage than good.

As the Neretva has many endemic and fragile species of fish that are near extinction, introductions of the invasive species, Pike Perch (Stizostedion lucioperca L.), is completely destroying native endemic and highly endangered fish like Strugač (Leuciscus svallize svallize Heck. et Kn.) or (Squalius svallize). and Glavatica (Salmo marmoratus) (also known as Gonjavac).

This area has developed a tourism niche on the lake. With several good restaurants on its shore. The entire length of the lake is lined with pensions, hotels, private rooms and campgrounds. The lake has some of the best fishing in the country as proved by the locals standing on the side of the road selling their 'catches of the day' - large carp, trout, bass and other fish.

Jablanicko Lake is safe for swimming but we recommend it only to good swimmers as there is no lifeguards or any other safety mechanisms in case of an emergency. The campgrounds are very simple. There is access for campervans and places to pitch a tent but no hook-ups for electricity or water. The place is usually crowded with local people.

Thing we recommend is a train ride Sarajevo - Mostar - Sarajevo, and part by the Jablaničko lake, which by many is the European most beautiful one.
