The Middle Mississippi is relatively free-flowing. From St. Louis to the Ohio River confluence, the Middle Mississippi falls 220 feet (67 m) over 180 miles (290 km) for an average rate of 1.2 feet per mile (23 cm/km). At its confluence with the Ohio River, the Middle Mississippi is 315 feet (96 m) above sea level.
The Upper Mississippi River covers approximately half of the Mississippi River's length. About 850 miles (1,370 km) of the river is navigable from Minneapolis-St. Paul (specifically, the Coon Rapids Dam in the City of Coon Rapids, MN) to the Ohio River. The river sustains a large variety of aquatic life, including 127 species of fish and 30 ...
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 351 kilometres (218 miles). [10] These points make it difficult, if not impossible, to get an accurate measurement of the length of a river.
The longest rivers of the United States include 38 that have main stems of at least 500 miles (800 km) long. The main stem is "the primary downstream segment of a river, as contrasted to its tributaries". [1]
= 6,371.009 kilometers = 3,958.761 statute miles = 3,440.069 nautical miles. = Distance between the two points, as measured along the surface of the Earth and in the same units as the value used for radius unless specified otherwise.
River miles are used in a variety of ways. The Commonwealth of Pennsylvania, in its 2001 Pennsylvania Gazetteer of Streams, lists every named stream and every unnamed stream in a named geographic feature in the state, and gives the drainage basin area, mouth coordinates, and river mile, specifically the distance from the mouth of the tributary to the mouth of its parent stream.
