  List of rivers by length - Encyclopedia, History, Geography and Biography
The mouth of a river may be hard to determine in cases where the river has a large estuary that gradually widens and opens into the ocean; examples are the Amazon River and the Saint Lawrence River.
The length of a river between source and mouth may be hard to determine because of a lack of precise maps.
In these cases, the measured length of a river will depend on the scale of the map on which the measurement is based; in general, due to the fractal quality of a river, the larger the scale, the longer the resulting length measurement.

Rivers begin at their source in higher ground, either rising from a spring, forming from glacial meltwater, flowing from a body of water such as a lake, or simply from damp, boggy places where the soil is waterlogged.
River management is an ongoing activity as rivers tend to 'undo' the modifications made by man. Dredged channels silt up, sluice mechanisms deteriorate with age, levees and dams may suffer seepage or catastrophic failure.

The Yukon is the nation's third longest river; at 1,980 official miles from its source in the Nisutlin River of the Yukon Territory to its mouth in the Bering Sea, it is outstretched only by the Missouri (2,540 miles) and the Mississippi (2,350 miles).
The Tanana is one of four rivers on the USGS list that starts where a glacier ends; its official beginning, with the Nabesna River, is in meltwater from the Nabesna Glacier, 659 miles from its mouth.
Another listed river starting at a glacier is the Susitna, which gathers enough water from the Susitna Glacier and its tributary streams to achieve 15th rank in discharge---51,000 cubic feet each second on average.

 ofr87-242--Largest Rivers in the United States
Rivers are considered large on the basis of one or more of three characteristics: total length from source to mouth, area of basin (watershed) drained by the stream, and average rate of flow (discharge) at the mouth.
River lengths or river-length data are affected not only by some of the natural and artificial causes noted in the preceding paragraph, but also by the precision of various techniques of measurement, by the scale of available maps or aerial photographs, and by somewhat arbitrary decisions.
For the Mississippi River system as a whole, the longest continuous river channel is from the Missouri River headwater source in Montana to the mouth of the Missouri to the Gulf of Mexico, a combined length of about 3,710 miles.

 [E] - America's Troubled Waters : Can They be Saved?
Today, however, the river might more aptly be called the “Big Boondoggle.” Shortly after World War II, most of the river’s natural character was altered by dams and channels to create a deep, rock-lined barge canal and a series of slack water reservoirs.
Among the river’s more than 200 varieties of fish are such species as the striped bass, Atlantic sturgeon and American shad, all of which utilize it as a spawning ground.
This subsequently altered the river’s course, destroyed 5,000 feet of prime salmon spawning habitat, and formed a maze of warm-water ponds and wide shallow channels where salmon predators flourish.

 Case Study: The Tisza-Szamos Cyanide Pollution   (Site not responding. Last check: 2007-11-04)
The cyanide pollution of the rivers Szamos and Tisza was caused by AURUL, an Australian-Romanian joint venture that is situated in Romania’s Baia Mare (Nagybánya) region.
The average concentration — according to the data of the Hungarian environmental laboratories — was 18 mg/l in the six-hour run-off interval, which is 180 times more than the level of the “very polluted” category according to the Hungarian standards for surface waters.
The extremely critical water pollution was worsened due to the meteorological situation of the time (ice on the rivers, low flow rate) and as a consequence the pollution could not dilute rapidly.
