reaches town of Konjic. This section is also better known as the Upper Neretva (), and here river flows generally from east-southeast to north-northwest as do most Bosnia and Herzegovina rivers belonging to the Danube watershed, and covers some with an average elevation of 1.2%. Right below Konjic, the Neretva again expands into a third and largest valley which provided fertile agricultural land before it was flooded by large artificial reservoir, Jablaničko Lake, formed after construction of a Jablanica Dam near town of Jablanica. The second section begins from the confluence of the Neretva and the Rama between Konjic and Jablanica where the Neretva suddenly takes almost 180° degrees turn toward east-southeast and flows the short leg before reaches town of Jablanica, from which point turns again toward south. From Jablanica, the Neretva enters third and the largest canyon on its course, running through the steep slopes mountains of Prenj, Čvrsnica and Čabulja reaching in depth. Three hydroelectric dams operate between Jablanica and Mostar. When the Neretva expands for the second and final time, it reaches its third section. This area is often colloquially called the "Bosnian and Herzegovinian California". The last of its course forms wide alluvial delta, before the river empties into the Adriatic Sea.
