The Indigirka (Russian: Индиги́рка ; Yakut : Индигиир , romanized: İndigîr ) is a river in the Sakha Republic in Russia between the Yana to the west and the Kolyma to the east. It is 1,726 kilometres (1,072 mi) long. The area of its basin is 360,000 square kilometres (140,000 sq mi).
34-514: The isolated village of Russkoye Ustye , located on the delta of the Indigirka, is known for the unique traditional culture of the Russian settlers whose ancestors came there several centuries ago. Some historians have speculated that Russkoye Ustye was settled by Pomors in the early 17th century. In 1638 explorer Ivan Rebrov reached the Indigirka. In 1636–42 Elisei Buza pioneered the overland route to
68-469: A large delta , consisting of a number of streams (each one being labeled on Russian maps as a photo ka ( river arm )) and islands. About 100 kilometres (62 mi) before reaching the East Siberian Sea ( 70°48′45″N 148°54′58″E / 70.8126°N 148.9162°E / 70.8126; 148.9162 ), the river splits into two major northeast-flowing streams . The left (westernmost) arm
102-465: A locally recorded legend, the villagers' ancestors originally left European Russia during Ivan the Terrible 's persecution campaigns in the late 16th century, although, as Rasputin suggests, reaching the Indigirka may have taken them a long time. The first known record of the community of Russkoye Ustye is in the reports of the explorer Dmitry Laptev , who had to spend a winter there in 1739 when his boat

They can also occur inland, on alluvial fans , or where a tributary stream bifurcates as it nears its confluence with a larger stream. In some cases, a minor distributary can divert so much water from the main channel that it can later become
170-572: A single localion, which was given the name Polyarnoye. However, the inhabitants continued to refer to it colloquially as Russkoye Ustye, and this name was officially restored in 1988. A Siberian writer, Valentin Rasputin , dedicated a chapter of his non-fiction book, " Siberia, Siberia " (originally published in 1991) to the people of this isolated traditional community. Even though the locals "seemed to be fashioned entirely out of prejudice", he favorably compares their ability to pass moral judgments with

It is the largest river on the planet that links two major river systems. The Huai River in China splits into three streams. The main stream passes through the Sanhe Sluice, goes out of the Sanhe river, and enters the Yangtze River through Baoying Lake and Gaoyou Lake . On
272-753: Is known as the Russko-Ustyinskaya Protoka ; the right arm, the Srednyaya Protoka (Russian for the "Middle Arm"). Further downstream, the third major arm, the Kolymskaya Protoka splits off the Srednyaya Protoka as its right (eastern) distributary, thus justifying the "middle" moniker for the Srednyaya Protoka. While Srednyaya Protoka means the "Middle Arm", the names of the main western and eastern arms indicate their relative location as well. The Kolymskaya Protoka , or Kolymskoye Ustye
306-565: Is the arm one located on the eastern side, i.e. the "Kolyma side" of the delta (the arm closest to the Kolyma , the eastern neighbor of the Indigirka). The Russko-Ustyinskaya Protoka , apparently known earlier as simply Russkoye Ustye is the arm one located on the western side, i.e. the "Russian side" of the delta (meaning, the side closest to the (European) Russia). These days the name of the Russko-Ustyinskaya Protoka appears as if it were formed from
340-626: The Chersky Range . At the point where it crosses the Chemalgin Range the river narrows and flows into a deep gorge, forming rapids. Where it is joined by the Moma river from the southeast, the Indigirka reaches the Momo-Selennyakh Depression, a wide intermontane basin and the middle course of the river begins, where its valley expands. Turning northwards, the Indigirka cuts deeply across
374-730: The Clutha River , splits into two arms, the Matau and the Koua , some 10 kilometres from the South Island's Pacific Coast. A large island, Inch Clutha , lies between the two arms. Many of the rivers crossing the Canterbury Plains in the central South Island are braided rivers , and several of these split into separate branches before reaching the coast. Notable among these is the Rangitata River ,

The Bamu River splits into several channels close to its mouth, among them the Bebea , Bina , Dibiri , and Aramia . The Kikori River also splits into a multitude of channels as it crosses the plains close to the Gulf of Papua. The Purari River splits into three major channels as it approaches its mouth. New Zealand's second-longest river,

In North America such a branching river is called a braided river . In Louisiana , the Atchafalaya River is an important distributary of the Mississippi River . Because the Atchafalaya takes a steeper route to

Distributary A distributary , or a distributary channel is a stream channel that branches off and flows away from a main stream channel. It is the opposite of a tributary , a stream that flows towards and into another stream or river. Distributaries are

In British Columbia , Canada, the Fraser River has numerous sloughs and side-channels which may be defined as distributaries. This river's final stretch has three main distributaries: the North Arm and the South Arm , and a few smaller ones adjoining them. Examples of inland distributaries: The Casiquiare canal

Ust-Nera , a gold-mining center, is the largest settlement on the river. The Indigirka teems with a variety of fishes. Among the most valuable are several whitefish species, such as vendace , chir , muksun , inconnu ( nelma ), omul , etc. The Indigirka forms
680-507: The Indigirka river system. At about the same time, Poznik Ivanov ascended a tributary of the lower Lena, crossed the Verkhoyansk Range to the upper Yana, and then crossed the Chersky Range to the Indigirka. In 1642 Mikhail Stadukhin reached the Indigirka overland from the Lena. Zashiversk on the Indigirka was an important colonial outpost during the early days of Russian colonization. It

The locality's name is probably based on the name of the river channel on which it is located, and which, too, has been known historically as the Russkoye Ustye . These days the channel is also known under the name Russko-Ustyinskaya Protoka that is formed from the locality's name. The original name of the channel, Russkoye Ustye, can be loosely translated as "the westernmost arm" [of

Russkoye Ustye is located in the delta of the Indigirka River , about 80 kilometers (50 mi) from the fall of the main western channel of the Indigirka's delta into the East Siberian Sea of the Arctic Ocean . Russkoye Ustye was settled several centuries ago by ethnic Russians, who mixed to some extent with the indigenous Even people . As no agriculture is possible at this Arctic location, they developed an economy based on hunting, fishing, and trapping. Since

These terms may refer to a distributary that does not rejoin the channel from which it has branched (e.g., the North, Middle, and South Arms of the Fraser River , or the West Channel of the Mackenzie River ), or to one that does (e.g. Annacis Channel and Annieville Channel of
918-477: The name of the old Russian village Russkoye Ustye situated there, but originally the opposite is likely to have been the case, the village is named after the river arm (the Russkoye Ustye ) on which it was located. Several flat islands are formed by the channels of the delta. Listed from the east to the west, the major ones are: Russkoye Ustye Russkoye Ustye ( Russian : Ру́сское У́стье ; Yakut : Русскай Устье , romanized: Russkay ustye )

Historically, the peoples of Russkoye Ustye were spread out over tens of kilometers, living in solitary houses or tiny hamlets of three to four houses (there were six houses in the hamlet where Zenzinov stayed). Around 1940–1942, the authorities arranged for them to move into

Due to the remarkable geographic isolation of the settlement, its residents preserved much of their ancestors' beliefs, customs, and folklore into the 19th and 20th century, which made Russkoye Ustye a favorite destination for Russian ethnographers and cultural anthropologists, such as Gerhard von Maydell . Linguists visited

It is speculated that the original settlers, possibly of Pomor origin, arrived to the delta of the Indigirka as early as the first half of the 17th century. More skeptical researchers believe that the second half of the 17th century would be a more likely time for the initial settlement. According to

The noun ustye means "the river mouth" and the adjective Russkoye ("Russian") apparently refers to this channel's being the one located the farthest to the west (i.e., the one closest to [European] Russia). Similarly, the easternmost channel of the delta has been known as the Kolymskoye Ustye, i.e., the river mouth closest to the Kolyma (the Indigirka's neighbor to
