Distributary

North America

In Louisiana, the Atchafalaya River is an important distributary of the Mississippi River. Because the Atchafalaya takes a steeper route to the Gulf of Mexico than does the Mississippi, over several decades the Atchafalaya has captured more and more of the Mississippi's flow, after the Mississippi meandered into the Red River of the South. The Old River Control Structure, a dam which regulates the outflow from the Mississippi into the Atchafalaya, was completed by the Army Corps of Engineers in 1963. The dam is intended to prevent the Atchafalaya from capturing the main flow of the Mississippi and stranding the ports of Baton Rouge and New Orleans.

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:

• Teton River—a tributary of Henrys Fork in Idaho—splits into two distributary channels, the North Fork and South Fork, which join Henrys Fork miles apart.
• Parting of the Waters National Landmark within Wyoming's Teton Wilderness on the Continental Divide where North Two Ocean Creek splits into two distributaries, Pacific Creek and Atlantic Creek, which ultimately flow into their respective oceans.
• Kings River (California) has deposited a large alluvial fan at the transition from its canyon in the Sierra Nevada mountains to the flat Central Valley. Distributaries flow north into the Pacific Ocean via the San Joaquin River and south into an endorheic basin surrounding Tulare Lake.
• The Qu'Appelle River, in Saskatchewan and Manitoba, is a distributary of the South Saskatchewan River. Its flow is controlled by the Qu'Appelle River Dam. This dam forms the southern arm of Lake Diefenbaker.

South America

The Casiquiare canal is an inland distributary of the upper Orinoco, which flows southward into the Rio Negro, forming a unique natural canal between the Orinoco and Amazon river systems. It is the largest river on the planet that links two major river systems.

Europe

• The IJssel, the Waal and the Nederrijn (Lower Rhine) are the three principal distributaries of the Rhine. These are formed by two separate bifurcations within the Rhine–Meuse–Scheldt delta.
• The Gilgestrom, the Rußstrom and the Atmath are the three principal distributaries of the Nemunas Delta (Memeldelta).
• The Akhtuba River is a major distributary of the Volga. The bifurcation occurs close to, but before, the Volga Delta.
• The Tärendö River in northern Sweden is an inland distributary, far from the mouth of the river. It begins at the Torne River and ends at the Kalix River.
• The Little Danube in Slovakia branches off from the Danube near Bratislava, and flows into the Vah before rejoining the main river near Komárno. The area in the middle is the largest freshwater island in Europe.
• The Abbey River, Limerick, in Ireland is a distributary arm of the River Shannon. It rejoins the Shannon to form an island upon which King John's Castle is built.

Asia

Eastern Asia

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 the east bank of Hongze Lake, another stream goes out of Gaoliangjian Gate and enters the Yellow Sea at the port of Bidan through Subei Guan'gai Zongqu, the main irrigation channel of Northern Jiangsu); its total length is 168 kilometers. The third stream leaves the Erhe lock on the northeast bank of Hongze Lake, passes the Huaishuhe River to the north of Lianyungang city, and flows into Haizhou Bay through the Hongkou.

Southeast Asia

The Tha Chin River and Noi River are distributaries of the Chao Phraya River in Thailand, splitting off from the latter about 200 kilometers upstream from the Bay of Bangkok.

The Brantas River in East Java, Indonesia, branches off into two distributaries, Mas River, also known as Surabaya River, and Porong River.

The Hong River in Northern Vietnam has notable distributaries such as the Day River, Ninh Co River and the Luoc River. All of these rivers empty into the Gulf of Tonkin.

Indian Subcontinent

• Kollidam River is a distributary of the Kaveri River.
• Himalayan rivers including Ganges, Brahmaputra and Indus plus many tributaries form inland distributaries over vast alluvial fans as they transition from the mountain region to the flat Indo-Gangetic Plain. These areas are highly flood-prone, for example the 2008 Bihar flood on the Kosi River.
• Padma River is the main distributary of the Ganges in Bangladesh.
• Hoogli River is a Ganges distributary that flows through India, whereas most of the Ganges-Brahmaputra complex enters the sea through Bangladesh.
• Nara River is a distributary of the Indus River.

Africa

• The Nile River has two distributaries, the Rosetta and the Damietta branches. According to Pliny the Elder it had in ancient times seven distributaries (east to west):
  • The Pelusiac
  • The Tanitic
  • The Mendesian
  • The Phatnitic
  • The Sebennytic
  • The Bolbitine
  • The Canopic

See History of the Nile Delta.

• The Okavango River ends in many distributaries in a large inland delta called the Okavango Delta. It is an example of distributaries that do not flow into any other body of water.

Oceania

Australia

A number of the rivers that flow inland from Australia's Great Dividing Range form distributaries, most of which flow only intermittently during times of high river levels and end in shallow lakes or simply peter out in the deserts. Yarriambiack Creek, which flows from the Wimmera River into Lake Coorong, and Tyrrell Creek, which flows from the Avoca River into Lake Tyrrell, are two distributaries in Victoria. The Narran River flows from the Balonne River in Queensland into Narran Lake in New South Wales.

Papua New Guinea

Many of Papua New Guinea's major rivers flow into the Gulf of Papua through marshy, low-lying country, allowing for wide, many-branched deltas. These include the Fly River, which splits into three major and several minor rivers close to its mouth. 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

New Zealand's second-longest river, 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 two arms of which are separated by the low-lying Rangitata Island.
