Its total length is , of which are in Bosnia and Herzegovina, while the final are in the Dubrovnik-Neretva County of Croatia. The Neretva watershed is in total; in Bosnia and Herzegovina with the addition of the Trebišnjica river watershed and in Croatia, . The average discharge at profile Žitomislići in Bosnia and Herzegovina is /s and at the mouth in Croatia is /s in addition to the Trebišnjica River's /s. The Trebišnjica River basin is included in the Neretva watershed due to a physical link of the two basins by the porous karst terrain. The hydrological parameters of Neretva are regularly monitored in Croatia at Metković.


Sections

Geographically and hydrologically the Neretva is divided into three sections. Its source and headwaters

The river source is at 1,227 meters above sea level and consists of five small and distinct wellsprings. On its 90 kilometers course through the first section the Neretva cuts two distinct deep and narrow canyons and two distinct wide and fertile valleys, around

and then around Glavatičevo, before it reaches town of Konjic. This section is also better known as the Upper Neretva ( bs, Gornja 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

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

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.

Upper Neretva

The upper course of the Neretva river is simply called the Upper Neretva '' ( bs, Gornja Neretva)''. It includes numerous streams and well-springs, three major glacial lakes near the river and more lakes scattered across the mountains of Treskavica and Zelengora in the wider area, mountains, peaks and forests, flora and fauna of the area. The Upper Neretva has water of Class I purity and is almost certainly the coldest river water in the world, often as low as 7–8 degrees Celsius in the summer months. Rising from the base of the Zelengora and Lebršnik Mountain, Neretva headwaters run in undisturbed rapids and waterfalls, carving steep gorges reaching in depth.


Rakitnica River

The Rakitnica is the main tributary of the first section ''( bs, Gornja Neretva)''. The Rakitnica River forms a long canyon, out of its length, that stretches between Bjelašnica and Visočica to the southeast from Sarajevo. From the canyon, a hiking trail along the ridge of the Rakitnica canyon drops 800 m below, to the famous village of

The village is inaccessible from the first snows in December until late April and sometimes even later, except by skis or on foot.


Middle Neretva

Hydrographically the Middle Neretva section begins from town of Konjic, but after the construction of Jablanica Hydroelectric Power Station and flooding of large fertile valley between Konjic and Jablanica, known simply as "Neretva" since Middle Ages, the new point for hydrographical division became dam of the Jablanica HPP where also is a place of confluence of the rivers Neretva and Rama. Here the Neretva river suddenly takes almost 180° degrees turn toward east-southeast and flows the short leg before it reach town of Jablanica. From this point it turns again toward south and enters third and the largest canyon on its course, running through the steep slopes of the mountains of Prenj, Čvrsnica and

, reaching between in depth. This section is characterized with steep and relatively narrow canyon, and rugged karstic geology and hydrology. Four enormous vales-size rifts appear in the mountainsides forming canyon walls, two from each sides of the river, intersecting with the main canyon almost perpendicularly. The Neretva receives only four small streams in this section, all running through these side-vales, which are relatively short. Going downstream from Jablanica, first two from each side are the Glogošnica stream, its eponymous canyon and small village, at the left, and the Grabovica stream with eponymous canyon and historical village, from the right side. Further downstream two much larger vales appear again on each side, first on the right the stream of Drežanka and its large and steep valley, with two eponymous villages, Donja (Lower) and Gornja (Upper) Drežnica, and than Mostarska Bijela, as one of the most pristine vales in Bosnia and Herzegovina, with its eponymous uniquely characteristic subterranean stream, embedded deep into the Prenj mountain, on the left. Although these streams are of low outflow, there are also numerous wellsprings rising on both sides of the canyon at the river banks, with high-capacity discharge. Three large hydroelectric power stations operate in this section of the Neretva, between Jablanica and Mostar, namely Grabovica HPP, Salakovac HPP and Mostar HPP.


Lakes

Jablanica lake Jablanica ( sr-cyr, Јабланица) is a common South Slavic toponym, derived from ''jablan'', "Lombardy poplar", literally meaning "place of lombardy poplar". It may refer to: Albania * Jablanica Mountain, in eastern Albania and the west of ...
is a large artificial lake on the Neretva river, right below Konjic where the Neretva expands into a wide valley. The river provided fertile, agricultural land before the lake flooded most of it. The lake was created in 1953 after construction of a largegravitational hydroelectric dam near Jablanica in central Bosnia and Herzegovina. The lake has an irregular, elongated shape, and its width varies along its length. The lake is a popular vacation destination.


Lower Neretva

Downstream from the confluence of its tributaries, the Trebižat and Bregava Rivers, the valley spreads into an alluvial fan covering . The upper valley, the 7,411 hectares in Bosnia and Herzegovina, is called Hutovo Blato.


Hutovo Blato wetlands

The Neretva Delta has been recognised as a Ramsar site since 1992, and Hutovo Blato since 2001. Both areas form one integrated Ramsar site that is a natural entity divided by the state border. The

, covers protected areas in Croatia and Bosnia and Herzegovina. Since 1995, Hutovo Blato has been protected as ''Hutovo Blato Nature Park'' and managed by a public authority. The whole zone is protected from human impact and provides habitat for many plants and animals. The historical site Old Fortress Hutovo Blato is in the Nature Park. Gornje Blato- Deransko Lake is supplied by the karstic water sources of the Trebišnjica River, emerging from bordering hills. It is hydro-geologically connected to the Neretva River through its effluent, the Krupa River, formed out of five lakes (Škrka, Deranja, Jelim, Orah, Drijen). Large portions are permanently flooded and isolated by wide groves of reedbebds and trees. It represents a more interesting preserved area.


Krupa River

The Krupa River is a Neretva left tributary and the main water current of Hutovo Blato, which carries the waters from Gornje Blato and Svitavsko Lake into the Neretva River. The length of Krupa is with an average depth of . The Krupa does not have a specific source, but is an arm of Deransko Lake. Also, the Krupa is a unique river in Europe, because it flows both ways. It flows both towards and back from its mouth. This happens when a high water level causes Neretva to push Krupa in the opposite direction.


Neretva Delta wetlands

Passing towns and villages in Bosnia and Herzegovina, the Neretva spills out into the Adriatic Sea, building a wetland delta that is listed under the Ramsar Convention as internationally important. In this lower alluvial valley in Croatia, the Neretva River splinters into multiple courses, creating a delta covering approximately 12,000 hectares. The delta in Croatia has been reduced by extensive land reclamation projects, reducing the river flows to just three branches from the original twelve. The marshes, lagoons and lakes that once dotted this plain have disappeared and only fragments of the old Mediterranean wetlands survive. Wetlands, marshes and lagoons, lakes, beaches, rivers, hummocks (limestone hills) and mountains compose the delta, with five protected areas with a total area of 1,620 ha. These are ornithological, ichthyologic and landscape reserves.


Endemic and endangered species

Dinaric karst water systems support 25% of the total of 546 fish species in Europe, many endemic. The Neretva River, together with four other areas in the Mediterranean, has the largest number of threatened freshwater fish species. The degree of endemism in the karst ecoregion is greater than 10%. Multiple fish species have small habitats and are

, so they are included on the Red List of endangered fish . The Adriatic basin has 88 species of fish, of which 44 are Mediterranean endemic species, and 41 are Adriatic endemic species. More than half of the Adriatic river basin species of fish inhabit the Neretva, the Ombla, the Trebišnjica, the Morača Rivers and their tributaries, and more than 30 are endemic.


Invasive species

A pike perch (''Sander lucioperca'' Linnaeus 1758) (also see ''Sander'' (genus)) population in the Neretva River watershed was observed in 1990 for the first time. The Rama River, a right tributary of the Neretva, and its

species. Population estimates have increased in the Neretva accumulation lakes. This fact confirms previous scientific assumptions of Škrijelj (1991, 1995), who predicted the possibility of pike perch displacement (migration) from Ramsko Lake to the Rama River and then further downstream to the river and its lakes. In 1990 the perch population made up 1.95% of the fish population in Rama Lake. Within a decade this rose to 25.42% in the nearby Jablaničko Lake. The fast pace of pike perch population growth and displacements is expected to match the environmental conditions from the mid-ecological valence of this fish. In this sense, it is the established continuous and accelerated growth of the population dynamics of pike perch in Jablaničko Lake, a relatively good representation in

The benefits brought by hydroelectric dams have come at an environmental and social cost. The waters of the Neretva river with its two main tributaries, the Rama and the Trebišnjica, are already harnessed by 9 (nine) Hydroelectric power plants with large dams, four on Neretva main stream, one with a major dam on the Rama tributary, and another three on the Trebišnjica River.

Projects in Upper Neretva

The government of the Bosnia and Herzegovina has unveiled plans to build three more hydroelectric power plants with dams over 150.5 metres in height upstream from the existing plants, beginning with Glavaticevo Hydro Power Plant in the village of Glavatičevo, then going upstream to Bjelimići Hydro Power Plant and Ljubuča Hydro Power Plant located near the eponymous villages; and another, by the Republic of Srpska, at the Neretva headwaters gorge, near the source of the river. It is similarly opposed by environmental organizations and NGO's, such as Zeleni-Neretva Konjic and the World Wildlife Fund. Meanwhile, Bosnia and Herzegovina entity,

, was preparing a parallel plan to form a large, protected area as a national park which would include the entire region of Gornja Neretva ''( en, Upper Neretva)'', and have within the park the three hydroelectric plants. The latest idea is that the park should be divided in two, where the Neretva should be excluded from both and would become the boundary between parks. Those who oppose the plan wish to have the area turned into the ''National Park of Upper Neretva'' and would leave the park without substantial development.Silenced Rivers: The Ecology and Politics of Large Dams, by Patrick McCully, Zed Books, London, 1996


Projects in Ulog

Since 2000's, the other entity of Bosnia, Republica Srpska, developed plans to construct up to eight Hydroelectric power plants, seven small hydroelectric power plants, and one large, namely ''HE Ulog'', on the stretch of the Neretva with high ecological value, which lies within the entity administrative lines. This stretch consists of around 40 kilometers of the Neretva course between its source and entity line at

. Irregularities in planning and design, flawed the environmental impact study and the complete absence of research work on the ground related to the geological instability of the terrain, as well as irregularities in the implementation of tenders and the issuance of environmental and construction permits, are particularly noteworthy. In the environmental impact study, the only significant impact, one that should be reflected on the downstream part of the Neretva watercourse, is completely ignored. Such drastic disregard in planning and designing, considering that the facilities of ''HE Ulog'' are located on the very line of demarcation of two ethnically based entities, which makes the downstream of the river located entirely in another administrative entity, where all the ecological consequences resulting from the use of Neretva water and the production of electricity will be felt exclusively, introduces, besides environmental, also an ethnic and political dimension to the issue.


The Upper Horizons - Trebišnjica

In recent times the Republic of Srpska government finished the project named ''The Upper Horizons'' ( bs, Gornji horizonti), a large hydroelectric project that diverted underground waters in the Neretva watershed to the Trebišnjica plant and others in the Trebišnjica basin. This project was opposed by NGO's in Bosnia and Herzegovina and Croatia. They argued that the project would increase

Cultural and historical significance


Early history

During antiquity, the Neretva was known as Narenta, Narona and Naro(n), and was the inland home to the ancient Illyrian tribe of Ardiaei. They became ship builders, seafarers and fishermen. Archaeological discoveries of Illyrian culture dealt both with daily and religious life such as the discovery of ancient Illyrian shipwrecks found in Hutovo Blato, in the vicinity of the Neretva River. After intense excavations in the area of Hutovo Blato in the autumn of 2008,

that probably functioned as a trading post, as well as many sunken boats, fully laden with wine pitchers – so-called '' amphorae'' – from the 1st century BC. Archaeologist Adam Lindhagen claimed that it was the most important Illyrian ruin.


Roman period

One of the most significant monuments of Roman times in Bosnia and Herzegovina is Mogorjelo. Located 1 kilometer south of the town of Čapljina, Mogorjelo remnants of the old Roman suburban ''Villa Rustica'' from the 4th century represents ancient Roman agricultural production and estate, mills, bakeries, olive oil refinery and forges. The Villa was destroyed in the middle of the 4th century, during the invasion of western Goths. Surviving residents did not restore it to its original splendor. The name of Mogorjelo is thought to be derived either from the Slavic word for "burn" (Slavic – goriti) or that at the end of the 5th century the church was built on the ruins of the Villa, and was dedicated to ''St. Hermagor – Mogoru''.


Middle Ages

In the Early Middle Ages, the South Slavic

culture survived.


Ottoman period

The Old Bridge was commissioned by Suleiman the Magnificent in 1557 to replace an older wooden suspension bridge. Construction began in 1557 and took nine years: according to the inscription the bridge was completed in 974 AH, corresponding to the period between 19 July 1566 and 7 July 1567. Memories and legends and the name of the builder, Mimar Hayruddin (student of the Old/Great Sinan ( Mimar Sinan / Koca Sinan), the Ottoman architect) were preserved in writing. Charged under pain of death to construct a bridge of such unprecedented dimensions, the architect reportedly prepared for his own funeral on the day the scaffolding was finally removed from the completed structure. Upon its completion it was the widest man-made arch in the world. Associated technical issues remain obscure: how the scaffolding was erected, how the stone was transported from one bank to the other, and how the scaffolding was maintained during construction. On 9 November 1993, during the war in Bosnia and Herzegovina it was destroyed by sustained artillery shelling. After the war, immediate plans were raised to reconstruct the bridge as a symbol of peace and ethnic harmony, literally bridging the two sides of the conflict. They attempted to reuse as much original material as possible. Salvage operations, funded by the international community, raised the stones and the remains of the bridge from the river bed. Missing elements or parts that were not usable were cut from the original quarry. Now listed as a World Heritage Site, the bridge was rebuilt under the aegis of UNESCO. Its 1,088 stones were shaped according to the original techniques, at a cost of about €12 million. The grand opening was held on 23 July 2004. It is traditional for the town's young men to leap from the bridge into the Neretva. The practice dates back to 1566, the time the bridge was built, and an event was held every summer in front of population. The first recorded instance of someone diving off the bridge is from 1664. In 1968 a formal diving competition was inaugurated and held every summer. Počitelj is situated on a hill near Mostar and is easily accessible by bus. As with many other Bosnian sites, this town is Ottoman in design. It is a historic fortified town with a hostel (

World War II: Battle of the Neretva

The famous '' Battle of Neretva'' is a 1969 Oscar-nominated motion picture depicting events from the Second World War and the actual Battle of the Neretva. Codenamed '' Fall Weiß'', the operation was a German plan for a combined attack launched in early 1943 against Yugoslav Partisans throughout occupied Yugoslavia. The offensive took place between January and April 1943. The operation used to be known, in socialist Yugoslav times, as the

In popular culture

Celebrated Bosnian and Herzegovinian poet, Mak Dizdar often used the river Neretva as motif in his poetry, alongside other historical, cultural and natural feature of his native Herzegovina. The famous '' Battle of Neretva'' is a 1969 Oscar-nominated motion picture depicting events from the World War II and the actual Battle of the Neretva. Many folk songs are written or performed with the Neretva as main theme.
