The lake was formed as a result of the construction of a high concrete arch dam on the Neretva River.
Water levels can drop by up to 30 meters during periods of high electricity demand at the Jablanica hydroelectric plant.
The reservoir area covers approximately 1,440 hectares during maximum capacity.
It acts as a primary habitat for several endemic fish species native to the Adriatic watershed.
During the summer, the lake's surface temperature is frequently ideal for swimming in designated coves.
The submerged village of Glogošnica is occasionally mentioned by local divers as a historical site now under the reservoir's surface.
Lake Jablanica is a 25-kilometer-long artificial reservoir created by the construction of the Jablanica Dam on the Neretva River in 1955. It serves as a regional hub for recreational boating, swimming, and freshwater angling, with popular fish species including carp, trout, and catfish. The lake spans multiple municipalities, including Jablanica and Konjic, and is bordered by steep, mountainous terrain typical of the Dinaric Alps. Its water level fluctuates significantly depending on the operations of the hydroelectric power plant. The surrounding landscape provides a distinct green-blue contrast against the limestone cliffs of the Prenj and Čvrsnica mountains. The area is frequented by local fishing enthusiasts who utilize the lake's diverse shoreline access points for small-craft mooring.

Check local water levels before bringing a boat, as low levels can expose jagged rocks near the shore.
Bring specialized footwear for rocky entry points if you plan on swimming.
Consult local anglers for the best spots, as fish movement changes with the depth fluctuations of the dam.
Avoid swimming near the dam structure itself for safety and security reasons.
Practice 'pack-in, pack-out' waste disposal to preserve the reservoir's water quality.
