When combined with its headstreams the 'Peace' and the 'Finlay', what becomes the second longest river in North America at 4,241 kilometres (2,635 mi)?
"southern branch (the Parsnip River) taken by Mackenzie. This northern branch would come to be known as the Finlay River. Finlay perhaps thought that this route might present a less complicated conduit to the Pacific. No record remains of the expedition except in the writings of Samuel Black, who ascended to the source of the Finlay in 1824, noting that ""he had studied Finlay’s chart."" Nonetheless, it would appear from the information Black had that Finlay had only made it as far as the Ingenika River, about 130 km north of the Finlay River's confluence with the Peace. Indeed, Black's"

"river basins that drain the continents. The largest river basin in North America is that of the Mississippi, covering the second largest watershed on the planet. The Mississippi-Missouri river system drains most of 31 states of the U.S., most of the Great Plains, and large areas between the Rocky and Appalachian mountains. This river is the fourth longest in the world and tenth most powerful in the world. In North America, to the east of the Appalachian Mountains, there are no major rivers but rather a series of rivers and streams that flow east with their terminus in the Atlantic"

"Mississippi River The Mississippi River is the second longest river of the United States and the chief river of the second-largest drainage system on the North American continent, second only to the Hudson Bay drainage system. Its source is Lake Itasca in northern Minnesota and it flows generally south for to the Mississippi River Delta in the Gulf of Mexico. With its many tributaries, the Mississippi's watershed drains all or parts of 32 U.S. states and two Canadian provinces between the Rocky and Appalachian Mountains. The main stem is entirely within the United States; the total drainage basin is ,"
"Missouri River is the longest river on the North American continent. The Missouri River was one of the main routes for the watershed expansion of the United States during the 19th century. The Ohio River runs 981 miles (1582 km) long, starting at the meeting of the Allegheny River and the Monongahela River in Pittsburgh, Pennsylvania; ending in Cairo, Illinois, where it then flows into the Mississippi. The Ohio River flows through six states, including, Illinois, Indiana, Ohio, Kentucky, Pennsylvania and West Virginia. The river is a location with the capacity to provide enough water for over five million people."
"Missouri River The Missouri River is the longest river in North America. Rising in the Rocky Mountains of western Montana, the Missouri flows east and south for before entering the Mississippi River north of St. Louis, Missouri. The river takes drainage from a sparsely populated, semi-arid watershed of more than half a million square miles (1,300,000 km), which includes parts of ten U.S. states and two Canadian provinces. When combined with the lower Mississippi River, it forms the world's fourth longest river system. For over 12,000 years, people have depended on the Missouri River and its tributaries as a source"
"all watercourses drain eastward toward the Atlantic, but a large number terminate in lakes and swamps or become lost in the thirsty soils of the Pampas and Patagonia. The four major rivers systems are those that feed into the Río de la Plata estuary, those made up of the Andean streams, those of the central river system, and those of the southern system. The Paraná, the second-longest river in South America after the Amazon, flows approximately 4,900 km and forms part of the borders between Brazil and Paraguay, and Paraguay and Argentina. Its upper reaches feature many waterfalls. It is"
"Amazon River The Amazon River (, ; Spanish and ) in South America is the largest river by discharge volume of water in the world, and by some definitions it is the longest. The headwaters of the Apurímac River on Nevado Mismi had been considered for nearly a century as the Amazon's most distant source, until a 2014 study found it to be the Cordillera Rumi Cruz at the headwaters of the Mantaro River in Peru. The Mantaro and Apurímac join, and with other tributaries form the Ucayali River, which in turn meets the Marañón River upstream of Iquitos, Peru,"

When measured from its longest stream source (most distant source from the sea), Brower's Spring in Montana, the source of the Missouri River, it has a length of 3,710 miles, making it the fourth longest river in the world after the Nile, Amazon, and Yangtze. When measured by the largest stream source (by water volume), the Ohio River, by extension the Allegheny River, would be the source, and the Mississippi would begin in Pennsylvania. The Mississippi River runs through or along 10 states, from Minnesota to Louisiana, and"

Yeats was ultimately pardoned: Edisto River The Edisto River is one of the longest free-flowing blackwater rivers in North America, flowing over 250 meandering miles from its sources in Saluda and Edgefield counties, to its Atlantic Ocean mouth at Edisto Beach, South Carolina. It rises in two main tributaries (North Fork & South Fork) from springs under the Sandhills region of West Central South Carolina, just to the south of the Piedmont Fall Line. It is the longest and largest river system completely contained by the borders of South"
"on for many years, the historic consensus of geographic authorities has been to regard the Amazon as the second longest river in the world, with the Nile being the longest. However, the Amazon has been measured by different geographers as being anywhere between long. It is often said to be ""at least"" long. The Nile is reported to be anywhere from . Often it is said to be ""about"" long. There are many factors that can affect these measurements. A study by Brazilian scientists concluded that the Amazon is actually longer than the Nile. Using Nevado Mismi, which in 2001"

By discharge, it is the second-largest contiguous U.S. river draining into the Pacific, after only the Columbia River, which has almost ten times the flow of the Sacramento. The Colorado River, which reaches the Gulf of California just south of the US-Mexico border near the southeast part of the state, is far larger than the Sacramento in terms of length and drainage area but has a"

The major drainage basins bordering that of the Sacramento are that of the Klamath in the north, the San Joaquin and Mokelumne to the south and the Eel River in the west. The Russian River also lies to the west and the endorheic (closed) Honey Lake and Eagle Lake basins to the north. On the east side are many endorheic watersheds of the Great Basin including the Truckee River and"

The river (main stem and North Branch) is approximately long, with a drainage area of about 14,700 square miles (38,000 km). In terms of area, this makes the Potomac River the fourth largest river along the Atlantic coast of the United States and the 21st largest in the United States.

It is a river in west-central Mexico that begins in Mexican Plateau at an altitude over above sea level, and ends where it empties into Lake Chapala, Mexico's largest lake, near Guadalajara, Jalisco. Lake Chapala is the starting point of Río Grande de Santiago, which some treat as a continuation of the Lerma"
