The Samarga (Russian: Самарга) is the northernmost river in the Primorsky Krai territory in the far eastern part of Russia. It is 218 kilometres (135 mi) long, and has a drainage basin of 7,760 square kilometres (3,000 sq mi),[1] making it the largest coastal river in the northern Sikhote-Alin mountain range. It flows into the Sea of Japan. The river system is a unique and relatively untouched centre of biodiversity in the Eastern Sikhote–Alin mountains because it is in a remote and mountainous region.
Location
The river is located in the northeast Primorsky territory of Russia. The northern and western boundaries of the river's watershed form the border between Primorsky territory and Khabarovsk territory. It confluences into the Sea of Japan at Samarga, a small town on the coast of the sea. In the estuary on the sea side, there is a kind of blind creek named the "Samrga duct" which extends for about 5 kilometres (3.1 mi).
Tributaries and watershed
Numerous small tributaries form a dense and extensive network in the watershed of the river.
The major left-hand tributaries of the Samarga, facing downstream, are: the Perepadnaya (30 kilometres (19 mi) long), the Dagdy (70 kilometres (43 mi)), the Moi (45 kilometres (28 mi)), the Isimi (45 kilometres (28 mi)), and the Agzu (30 kilometres (19 mi)).[2] The Sobu, Zova, Dzolu, Kalashnikov, Takhalo, and Kipreinyi, among others, are minor tributaries.
The major right-hand tributaries are: the Pukhi (60 kilometres (37 mi) long), the Kuksi (30 kilometres (19 mi)), and the Bolshaya Sokhatka (36 kilometres (22 mi)).[2] The Bugu, Zaami, and Unty are minor tributaries.
The Samarga’s average discharge is between 74 and 242 cubic metres (2,600 and 8,500 cu ft) per second. Its catchment area is around 7,760 square kilometres (3,000 sq mi).[3] The length of the watershed boundary is 515 kilometres (320 mi). Floods are common in the summer and autumn.
Fish
The Samarga watershed is so far the only place in the Primorsky territory with very high fish biodiversity and high natural fish productivity. The diversity of habitats provides for a wide variety of fish species.
A wide variety of fish, nearly 20 species –such as
The production topography of the Samarga is also very interesting. The lowest part of the river – from Unty Creek to the river mouth – is a zone of

There are currently four small towns in the area: Yedinka, Peretychikha, Samarga and Agzu in the watersheds of the Yedinka and Samarga. According to the 2001 Census, the total population in the riverine watersheds is about 800 people, representing various ethnic groups. Out of this number, 140 belong to the
