mouth As a result, the length measurements of many rivers are only approximations In particular, there has long been disagreement as to whether the Amazon or the Nile is the world's longest river The source of a river may be hard to determine because a river typically has many tributaries Among the many sources, the one that is farthest away from the mouth is considered as the source of the river, thus giving a maximal river length In practice, the tributary with the farthest source is not always the one given the name of the river For example, the farthest source of the Mississippi River

system is the source of the Jefferson River, a tributary of the Missouri River which in turn is a tributary of the Mississippi However, a different (and shorter) tributary is identified as the

Mississippi When the river is measured from mouth to farthest source, it is called the Mississippi-Missouri-Jefferson Also, it is hard to state exactly where a river begins as very often rivers are formed by seasonal streams, swamps, or changing lakes In this article, length means the length of the longest continuous river channel in a given river system, regardless of name

The mouth of a river is hard to determine in cases where the river has a large estuary that gradually widens and opens into the ocean; examples are the River Plate and the Saint Lawrence River Some rivers like the Okavango or Colorado not have a mouth; instead they dwindle to very low water volume and eventually evaporate, or sink into an aquifer, or get diverted for agriculture The exact point where these rivers end will vary seasonally

The length of a river between source and mouth may be hard to determine due to issues of map scale Small scale maps (those showing large areas) tend to generalize, or "smooth" lines more than large scale maps (those showing small areas) According to the generally accepted ideal, length measurements should be based on maps that are of a large enough scale to show the width of the river, and the path measured is the path a small boat would take down the middle of the river Even when detailed maps are available, the length measurement is not always clear A river may have multiple channels, or anabranchs The length may depend on whether the center or the edge of the river is measured It may not be clear how to measure the length through a lake Seasonal and annual changes may alter both rivers and lakes Other factors that can change the length of a river include cycles of erosion and flooding, dams, levees, and channelization In addition, the length of

meandering can change significantly over time due to natural or artificial cutoffs, when a new channel cuts across a narrow strip of land, bypassing a large river bend For example, due to 18 cutoffs created between 1766 and 1885 the length of the Mississippi River from Cairo, Illinois, to

New Orleans, Louisiana, was reduced by 218 miles (351 km).[1]

These points make it difficult, if not impossible, to get an accurate measurement of the length of a river The varying accuracy and precision also makes it difficult to make length comparisons between different rivers without a degree of uncertainty

One should take the aforementioned discussion into account when using the data in the following table For most rivers, different sources provide conflicting information on the length of a river system The information in different sources is between parentheses

] Notes

 When the length of a river is followed by an asterisk , it is an average of multiple

information sources If the difference in lengths between given information sources is

significant, all lengths are listed Likewise, if the lengths from secondary information sources are similar, they are averaged and that figure has an asterisk

 Scientists debate whether the Amazon or the Nile is the longest river in the world

(11)

New evidence, (dated 16 June 2007) obtained from a high-altitude scientific venture in the

Andes, claims that "the Amazon is longer than the Nile by 100km, with its longest headwater

being the Carhuasanta stream originating in the south of Peru on the Nevado Mismi

mountain's northern slopes and flowing into the Río Apurímac"[6] However, the origin of the

river at Nevado Mismi had already been known more than one decade earlier (see Jacek Palkiewicz), and satellite based measuring from this origin to the Amazon mouth has resulted in not more than 6,400 km (see "discussion" and Discussion Apurímac River)

 Generally, the most commonly used/anglicised name of the river is used The name in a

native language or alternate spelling may be shown

 The exact percentage of each river in countries may be disputed (including the effects of

political frontier disputes) or unknown

Louis Saint Lawrence River along the New York-Quebecborder
