The world’s shortest rivers
Apr
Powerful, long, meandering lazily for hundreds and sometimes thousands of kilometers – this is the image that usually comes to mind when we think of a river. Meanwhile, there are watercourses in the world so short that a minute’s walk is enough to walk along the entire course. Despite their small size, they still remain full-fledged rivers: they have a clear source, current and outlet. The world’s shortest rivers are intriguing – they are small, but geographically no less fascinating.
The world’s shortest rivers – why isn’t their ranking obvious?
Classifying the world’s shortest rivers is not at all as obvious as it might seem. The problem begins already at the stage of measurement, because in the case of such short watercourses it is of great importance where the source ends and the actual course of the river begins, as well as where the mouth should be determined. This is why there is no single universally valid ranking, and there have been disputes over the places in such rankings for years.
Nevertheless, several rivers are regularly indicated as extremely short. It is to them that we will take a closer look.
Reprua River: shortest and coldest
In the vicinity of Gagra, on the Black Sea, flows the Reprua, an 18-meter-long river, although some descriptions also mention a value of 27 meters. Its water flows from a karst spring associated with the Arabika massif – an area famous for one of the deepest cave systems on Earth – and after only a dozen meters it flows into the Black Sea.
The uniqueness of the Reprua is due not only to its length, but also to the characteristics of the water: icy, maintaining a temperature of about 10-11°C all year round, very clear and constantly fed by underground water flowing through a system of limestone rocks. Thanks to this, Reprua is considered one of the coldest rivers of the Black Sea coast. Interestingly, part of its resources go to the water supply system of the Gagra region, although this only accounts for about one-tenth of the total flow.
Its name refers to an Abkhazian legend about a warrior and his siblings. According to it, the river was formed from the tears of three sisters, daughters of an underground spirit, who came out of a cave to find their brother. When they learned that he had fallen in battle, they began to mourn his fate, and their tears formed three small rivers, including Reprua.
Tamborasi River – almost square
In the Indonesian province of Southeast Sulawesi, in the regency of Kolaka, flows the Tamborasi, a river most often described as about 20 m long. It is about 15 m wide, which, with such a short course, gives it quite remarkable proportions. It flows from an underground spring at the foot of a rocky hill, crosses a narrow coastal strip and, after less than 20 m, flows into Bone Bay.
What sets Tamborasi apart is not only its proportions, but also its surroundings. The river runs right next to the beach, amidst tropical greenery, and its water is sometimes described as very clear and having a distinctly turquoise hue. As a result, it gives the impression of a natural pool or a short link between the source and the sea, rather than a classic river. It is this contrast – microscopic in length and very picturesque in location – that has made Tamborasi one of Indonesia’s most recognizable geographical peculiarities.
Ombla River as a source of water and energy
In the Croatian village of Komolac, not far from Dubrovnik, there is the Ombla – a river about 30 meters long. It flows from a powerful karst spring at the foot of the Golubov Kamen massif and after just a few dozen meters joins the waters of the bay that is part of the Adriatic – Rijeka Dubrovačka.
The Ombla has been used as part of Dubrovnik’s water supply system since 1897, and remains an important source of drinking water for the city today. Mills have also long been associated with the river, and in recent years the topic of building a hydroelectric power plant has been regularly revisited. However, the project is highly controversial due to concerns about nature, the karst system and the safety of the investment.
D River, or river-symbol
The D River flows in the US state of Oregon, connecting Devils Lake to the Pacific Ocean at Lincoln City. The official Oregon State Parks website states that its length is 120 feet, or about 36.6 meters, although older listings also showed a figure of 440 feet (about 134 meters). Its course can be traced at a glance: it flows out of Devils Lake, crosses a narrow strip of the city and almost immediately ends at a wide beach on the Pacific Ocean.
The location of the D River, by the way, is one of its greatest peculiarities. The river flows practically in the heart of the seaside resort and has quickly become one of the most recognizable symbols of Lincoln City.
Roe River – famous for its shortness
In Great Falls, Montana, there is the Roe River, whose length is 201 feet, or about 61 meters. The entire course runs from Giant Springs to the Missouri River, thus from one of the largest freshwater springs in the United States to one of the most important rivers in North America. This juxtaposition alone is impressive: a powerful spring with a very high capacity and a river so short that the whole thing can be encompassed by a glance.
Today it remains a major attraction at Giant Springs State Park and a place frequented by tourists who want to see for themselves how short a river can be.
Dispute over the world’s shortest river
It was the D River and the Roe River that for years stood at the center of the most famous dispute over the title of the world’s shortest river. First the D River was pointed out, then – since 1989. – the place was taken by the Roe River. It was not just a geographical dispute, by the way – the residents of both localities were heavily involved in the battle for the record, treating it as a source of local pride and a basis for promotion.
This fierce rivalry between the two localities has grown to such an extent that in 2006. Guinness World Records dropped the world’s shortest river category altogether, deeming it too difficult to conclusively determine.
