History of the Mississippi<\/h2>\n

The Mississippi River has a history that spans thousands of years, from its origins as a small, seasonal stream to its current status as a major North American waterway. Over the centuries, it has served as an important spiritual and material resource for the many cultures that have resided along its banks. Primarily, it served as a crucial transportation route for Native American societies and early settlers alike. As with many North American rivers, the Mississippi has witnessed a long history of industrialization, navigation, and agricultural development. From the mid-19th century onwards, it became a major hub of commercial and industrial growth, with many cities and towns forming around the river’s various bends, levees, and tributaries.<\/p>\n

Composition and Dimensions of the Mississippi River<\/h2>\n

The Mississippi River, at over 2,000 miles long, is one of the world’s longest waterways. It’s usually stated as being 2,320 miles long, but this figure can fluctuate depending on conditions and the accuracy of measurements taken. The Mississippi is part of the combined 4,000-mile-long Mississippi-Missouri-Ohio river system, making it even longer.
\nThe Mississippi originates in Lake Itasca, Minnesota and ends at its mouth in the Gulf of Mexico near New Orleans, Louisiana. Its drainage basin covers about 1.25 million square miles in 31 states, from Minnesota in the North, to Louisiana in the South. The width of the Mississippi’s main channel, or deepest part, varies depending on the climate and flow conditions. It can be anywhere from 50 to 70 feet wide at its narrowest points. At its widest parts, the river can measure up to 110 feet wide.<\/p>\n

The Flow of the Mississippi River<\/h2>\n

The Mississippi River’s flow is greatly affected by many human influences, such as dams, levees, and other engineering works. Additionally, the river has experienced several natural disasters, including major floods and droughts, which can drastically change the water level in certain parts of the river.
\nThe river’s flow is primarily controlled by the two main tributaries, the Missouri and Ohio rivers. These rivers also wax and wane based on the water conditions. During flooding events, the combined flow of the Mississippi-Missouri-Ohio river system can be as massive as 3.2 million cubic feet per second—much faster than the average flow of 600,000 cubic feet per second.<\/p>\n

Navigability of the Mississippi River<\/h2>\n

The Mississippi River is naturally a very navigable river and is also an important transportation route for water borne cargo. The first steamboat to navigate on the Mississippi was the Zebulon Pike in 1811. Commercial navigation on the river soon followed and has remained a vital part of the river’s activity throughout its history.
\nThe U.S. Army Corps of Engineers maintains many levees along the Mississippi, but flooding is still a major hazard and has caused untold damage over the centuries. Countless communities, landscapes, and infrastructure have been destroyed due to floods, including the Great Mississippi River Flood of 1927, a natural disaster which resulted in over 700,000 people being displaced and billions of dollars of damage.
\nIn terms of actual navigability, the Mississippi is typically suitable for a wide range of vessels. For example, the U.S. Coast Guard allows vessels up to 1,000 feet long, 150 feet wide, and 50 feet draft to safely navigate the river.<\/p>\n
