river flowing in Bosnia and Hercegovina and in Croatia. The Neretva River rises on Lebršnik Mountain and flows northwest past Konjic to Jablanica (Jablaničko) Lake, then southwest via Mostar to enter the Adriatic Sea. Its total length is 140 miles (225 km). The upper course of the river runs through canyons and gorges in uninhabited country. The Jablanica Dam created a lake for a hydroelectric station. The lower valley of the Neretva enjoys the Mediterranean climate of the Dalmatian coast.
