The Mississippi River is one of the most important rivers on the North American continent, stretching over 2,300 miles from its source in northwestern Minnesota to its confluence with the Gulf of Mexico in the southern state of Louisiana. It is not only the fourth longest river in the United States – it is also the largest and most powerful river in terms of moisture runoff and sediment deposition. The massive watershed of the Mississippi River supplies over three-fourths of the nation’s freshwater, waters over 26 states, and provides the culture and livelihood of millions of people. So the question remains: is the Mississippi River the biggest river?<\/p>\n

In terms of size, the Mississippi is not the largest river in the U.S. The Missouri River, which it meets downstream, is actually the longest at 2,341 miles in length. The Mississippi River itself is over 2,300 miles long, while the longest river in the entire world, the Nile, stretches over 4,160 miles. However, the Mississippi River has the largest drainage area among all North American rivers, with an estimated total drainage area of 1,245,000 square miles – that’s larger than the nations of Egypt and France combined. The river is responsible for draining nearly 40% of the United States, and supplying water to more than 600 tributaries across 26 states from Minnesota to Louisiana.<\/p>\n

The Mississippi is also powerful in terms of velocity and discharge rate. The average discharge rate for the Mississippi River is about 600,000 cubic feet per second – that’s enough to supply the entire water requirements of a city the size of Pittsburgh, Pennsylvania. The rate is even greater during the rainy season, reaching a peak of over 1 million cubic feet per second.<\/p>\n

The total volume of water discharged by the Mississippi River into the Gulf of Mexico each year is so significant that it is often referred to as the “third coast of the United States”. In addition to providing water to millions of people, the river supplies essential nutrients and vital sediment to the wetlands of the region, making it one of the most productive ecosystems in the world.<\/p>\n
