Overview
The Mississippi River is the second longest river in the United States and one of the most iconic in the country, considered to be the lifeblood of the American Midwest. The river forms a major portion of the boundary between the United States and Canada, moving through ten U.S. states and two Canadian provinces before ending in the Gulf of Mexico. The Mississippi River is inextricably linked to the history of the United States and continues to play a major role in the economy, transportation, ecology and culture of the region. This article will explore the geography of the Mississippi River, providing an overview of the continent in which it is located, as well as its physical features, major sources, and key watersheds.
Location
The Mississippi River is located in the North American continent, making it one of the most important rivers on the continent. It is often referred to as the “Father of Waters” and is one of the primary sources of transport for people and goods. Although the Mississippi River is the “longest in the U.S.,” it is actually quite short compared to other rivers in the world, such as the Amazon and the Nile.
The river starts in Lake Itasca, in north-western Minnesota, and travels southward for more than 2,320 miles before emptying into the Gulf of Mexico. Along the way, it passes through ten U.S. states and two Canadian provinces. The countries through which it flows and the cities it touches vary depending on the part of the river. For example, at its source the river only passes through Minnesota and Wisconsin, but further downstream it touches Illinois, Arkansas, and Louisiana, among others.
Physical Features
The Mississippi River is a deep and meandering river, with many curves, bends, and islands. It has several tributaries and relies upon several lakes, bayous, and swamps to regulate its flow and provide water. The main channel is deep enough to support large vessels in most sections, with the exception of the upper portions of the river, which can be treacherous to navigate.
The most remarkable feature of the river is the number of oxbow lakes, many of them created by the natural meandering of the river. Oxbow lakes are formed when the river takes a sharp turn, often leaving behind a large loop of water which eventually gets cut off from the main river.
Sources
Apart from Lake Itasca, which is considered the primary source of the Mississippi River, the river is also fed by numerous streams and other bodies of water. Some of the major tributary streams of the river include the Missouri River, the Ohio River, the Arkansas River, and the Red River, among others.
Each of these tributaries contributes to the overall volume of the Mississippi River, but the Missouri River is considered to be the longest and most important, contributing more than one-third of the total volume. The Ohio River, on the other hand, is the second largest contributor to the volume of the Mississippi River, while the Arkansas River is the third largest. Additionally, the Red River also contributes a significant amount of water to the total volume of the river.
Watersheds
The Mississippi River has a vast watershed, covering almost all of the central and northern part of the United States and a large portion of Canada. The watershed is divided into two distinct regions: the Upper Mississippi River Basin and the Lower Mississippi River Basin. The Upper Mississippi River Basin consists of parts of Minnesota, Wisconsin, Iowa, Illinois, Nebraska, South Dakota, North Dakota, and Arkansas, while the Lower Mississippi River Basin includes large portions of Louisiana, Mississippi, and Tennessee, among other states.
The Mississippi River Basin is rich in biodiversity and is home to a wide variety of wildlife, including numerous species of mammals, birds, reptiles, and fish. Additionally, the river also serves as a critical source of fresh water for millions of people in the United States and Canada.
Economy
The Mississippi River is an important artery for international trade and commerce in the United States and is a key contributor to the economy of the region. It is a major source of transportation for humans and cargo, as well as a source of power generation. Additionally, the river is home to numerous ports and terminals, which serve as hubs for international trade.
Moreover, the Mississippi River is also a major source of freshwater and also provides essential water resources for agricultural, industrial, and municipal uses. Due to its ecological significance and its critical economic importance, the river is heavily regulated by the United States Environmental Protection Agency (EPA).
Culture
The Mississippi River plays a large role in the culture of the region, as it has been an important part of the local folklore and the literary works of many well-known authors. The river has been famously mentioned in the works of authors such as Mark Twain and Ernest Hemingway, and its presence looms large in the music, movies, and popular culture of the United States.
In addition, the river has served as a backdrop for numerous films and television shows, such as “Huckleberry Finn” and “Hannibal,” which focus on the unique culture and environment of the region. Additionally, the river has been featured in numerous popular songs, serving as a potent symbol of freedom and adventure for millions of Americans.
Ecology
The Mississippi River plays a crucial role in the ecology of the region, serving as a major source of nutrients, sediment and organic material. In addition, the Mississippi River also serves as a major migratory route for numerous migratory birds, and its wetlands are a vital source of habitat and nesting grounds for various species of wildlife.
Additionally, the Mississippi River is an important source of freshwater and is home to numerous endangered species of fish. Additionally, the river plays an important role in regulating the water cycle and influencing polar ice cap melting and sea level rise.
Conservation Efforts
Since the Mississippi River is an integral part of the ecology and economy of the North American continent, numerous efforts are being made to ensure its preservation and conservation. Various organizations, such as the Mississippi River Basin Alliance and the Nature Conservancy, are working hard to ensure the enhancement and protection of the river and its tributary watersheds.
The U.S. government has also taken several measures to protect the river and its watershed, such as creating a network of national parks and monuments, as well as establishing laws to protect the river’s wetlands, floodways, and water quality. Additionally, the EPA is working hard to promote the conservation and protection of the Mississippi River, by implementing a number of initiatives and programs.
Pollution
The Mississippi River is vulnerable to pollution, due to the presence of numerous industrial and agricultural sites along its course. This has resulted in hazardous substances, such as nitrates, phosphorus, and pesticides, entering the river and contaminating its water supply. Moreover, runoff from cities and towns has also caused significant water pollution, resulting in the death of aquatic life and the degradation of water quality in the river and its tributaries.
Additionally, a number of pollutants, such as mercury and lead, are often deposited in the river by industry and mining activities. Furthermore, sewage and wastewater from urban centers can pollute the river, leading to the deaths of fish and other wildlife. Consequently, strong measures are necessary to protect the river and its tributaries from further pollution.
Floods and Levees
The Mississippi River basin is prone to severe flooding and extreme weather conditions, as the river is constantly changing its course. In order to protect against floods, vast levee systems are constructed along the river’s length, as well as numerous dams, floodways and other control systems.
These infrastructure projects are used to divert water from populated areas and to buffer the effects of extreme flooding. The levees and dams are also critical for the transportation of goods and services, as it allows for the creation of boat routes and canals for commercial vessels.
Sediments and Deltas
The Mississippi River carries vast amounts of sediment, which are deposited at the river’s end points and at several islands along its course. The accumulation of these sediment deposits forms several large and active deltas, which serve as powerful buffers against waves, storms, and hurricanes.
The largest and most active delta is the Mississippi Delta, which is located at the mouth of the Mississippi River and is composed of several large and small islands. The delta is home to a rich and vibrant ecosystem, composed of several species of plants and animals, as well as providing a habitat for several aquatic species unique to the delta.
Conclusion of the Mississippi River
