Question: The Crocs River is a tributary of a river given what nickname?
Context: Waterfall Country (or sometimes Waterfalls Country) is the name given to an area around the head of the Vale of Neath in South Wales where an unusually large number of publicly accessible falls are to be found.  The area is loosely defined but generally includes the group of falls on the Nedd Fechan, Pyrddin, Hepste and Mellte rivers, all of which lie in the country between the villages of Pontneddfechan and Ystradfellte in the southern part of the Brecon Beacons National Park.  All of these falls lie within or on the boundary of the county of Brecknockshire, now part of the unitary authority of Powys.  A few miles further west are Henrhyd Falls on the Nant Llech, a tributary of the Tawe and to the southwest are Melin Court Falls on the Melin Court Brook, a tributary of the River Neath.  These, along with Aberdulais Falls on the Dulais, a further tributary of the Neath are also encompassed by the term 'Waterfall/s Country' by some writers.

The Eerste River is a short river; its length has been given as 40 km.  The major tributary, Kuils River, is approximately 30 km long to its point of confluence with the Eerste River.

The length of the river given in the Infobox is the length using the shorter east channel. The Youghiogheny Scenic & Wild River is a river given special protected status by the state of Maryland.

This page is a list of present-day bridges over the River Seine and its channels, sorted by département, and then sorted from downstream to upstream.

The Saint John River (French: "Fleuve Saint-Jean" ; Maliseet: "Wolastoq"( )) is a river, approximately 418 mi long, located principally in the Canadian province of New Brunswick, but also in and arising from the province of Quebec and the U.S. state of Maine.

Along that portion of the Atlantic shoreline of North America that lies between the St. Lawrence River and the Mississippi River, the Saint John River is the second longest waterway; only the Susquehanna is longer.  It has been nicknamed the "Rhine of North America" for its scenery.  The river is regulated by hydro power dams located at Mactaquac, Beechwood, and Grand Falls, New Brunswick. The Ecorse River is an 18.8 mi river in southern Michigan.  Because of its small size, it is often identified as Ecorse Creek.  It flows through the Downriver section of Metro Detroit, and is a tributary of the Detroit River.  The early French settlers named it the "Rivière aux Écorces" ("bark river").  The river was given this name because of a custom, of the local Native American tribe, of wrapping its dead in birch or elm bark, and burying them at the mouth of the river.  The river has two branches, which meet at Council Point Park in the city of Lincoln Park, where Pontiac once held a council in 1763 before attacking Fort Detroit.
