Another potentially major threat to this species is habitat degradation: coral reefs in the Persian Gulf face bottom trawling, coastal development (especially large-scale land reclamation projects such as in the United Arab Emirates), Turkish dams on the Tigris-Euphrates river system, draining of marshes in Iraq, and oil spills.

Brisbane River cod

All naturally occurring Maccullochella cod in east coast drainages ultimately originate from Murray cod, Maccullochella peelii that entered an east coast river system, likely the Clarence, via a natural river capture event somewhere between 0.62 and 1.62 million years ago (mean estimate 1.1 million years ago), as estimated by DNA divergence rates.

Cetopsidae

East of the Andean Cordilleras, the Cetopsinae occur in the Aroa and Yaracuy River basins along the Caribbean versant of northern Venezuela, through the Orinoco River system and the coastal rivers of the Guianas, south through the Amazon basin to the southern portions of the Río de la Plata basin.

Chitwan National Park

In the north and west of the protected area the Narayani-Rapti river system forms a natural boundary to human settlements.

Cocoa Thrush

In the southeast Basin, it is in the Tapajos River and Xingu River drainages; also two thirds of the adjacent river system, the lower AraguaiaTocantins River drainage.

Cotter River System

A feature of the Namadgi National Park, the Cotter River System is one of two main sources for the Australian Capital Territory's water supply, the other being the Queanbeyan River located north of the Australian Capital Territory in New South Wales.

Nevertheless, the Cotter River System is a larger catchment area and due to recent drought conditions the Queanbeyan River has been seen as obsolete in comparison.

Eastern freshwater cod

Murray cod entered an east coast river system, likely the Clarence, via a natural event somewhere between 0.62 and 1.62 million years ago (mean estimate 1.1 million years ago), as estimated by DNA divergence rates.

Geography of Angola

South of the divide some rivers flow into the Zambezi River system and thence to the Indian Ocean, others to the Okavango River (as the Cubango River is called along the border with Namibia and in Botswana) and thence to Lake Ngami and the Okavango Swamp in Botswana.

Kopai River

Microliths of crystalline stone and petrified wood from about 1250–1000 BC are found in many places in the Ajay-Kunur-Kopai river system.

Kunur River

Microliths of crystalline stone and petrified wood from about 1250–1000 BC are found in many places in the Ajay-Kunur-Kopai river system.

Manggahan Floodway

On September 26, 2009, at about 6:00 pm PST, the 50-mph "Tropical Storm Ketsana" (called "Ondoy" in the Philippines) hit Metro Manila and dumped one month's rainfall in less than 24 hours, causing the Marikina River system, including the Manggahan Floodway, to burst its banks very rapidly.

Mountain galaxias

They are found from southern Queensland to the Adelaide Hills in South Australia, and while occurring widely in the Murray-Darling river system, are also found in eastern and southern coastal systems as well.

Murray River Flag

The Murray River Flag is flown from paddle steamers and other vessels in the Australian States of Victoria and South Australia that ply the waters of the Murray-Darling river system.

Ringed Antpipit

The range of the Ringed Antpipit is the entire Amazon Basin, the Guianan region, Marajó Island, and the southeast Orinoco River Basin region in eastern Venezuela; also the downstream half of the neighboring Amazon Basin river system in the southeast, the Araguaia-Tocantins River, with the range ending easterly on the Atlantic coast of Brazil's Maranhão state.

Siniloan River

The Siniloan River (Tagalog: Ilog ng Siniloan), also known as the Romelo River, is a river system that runs through Siniloan, Laguna on the island of Luzon, in the Philippines.

Slate-coloured Hawk

This corridor is about 700 km wide, and includes the confluence areas downstream of the major rivers: Rio Negro, Madeira, Tapajós, Xingu, and the outlet section of the Tocantins River in the southeast Basin's neighbouring river system, Araguaia-Tocantins.

Soča

According to the Roman historian Strabo, the river named Aesontius which in Roman times flowed past Aquileia to the Adriatic Sea was essentially the Natisone and Torre river system.

Spotted galaxias

This may cause a re-evaluation of the spotted galaxias specimens occasionally recovered in the Murray-Darling river system, which until now were assumed to be accidental translocations via the Snowy Mountains Hydro-Electric Scheme.

Timeline of Goan history

One person was killed during violent protests by farmers and environmental activists opposed to the construction of a Thapar-DuPont Nylon 6,6 nylon cord yarn factory which they feared would pollute the state's extensive river system.

Trinity Broads

Situated to the north west of Caister-on-Sea, the Trinity Broads are on a tributary of the River Bure, but there is no navigable link to the main river system, and they are therefore virtually undisturbed.

Virgin spinedace

Populations are known at various locations in the Virgin River system, including the North Fork and East Fork of the Virgin River in Zion National Park, the Santa Clara River, Beaver Dam Creek, and Ash Creek.

White Nile

The Bahr al Jabal passes through Juba, the capital of South Sudan, which is the southernmost navigable point on the Nile river system, and then to Kodok, the site of the 1898 Fashoda Incident that marked an end to the 'Scramble for Africa'.
