SUB-BASIN PROFILE
Lower Mississippi River Sub-basin
The Lower Mississippi River Basin is a crucial and dynamic region in the United States, extending from Cairo, Illinois, to the Gulf of Mexico. Here’s an overview:
Area: The basin covers parts of several states, including Illinois, Missouri, Kentucky, Tennessee, Arkansas, Mississippi, and Louisiana.
Length: The Lower Mississippi River flows approximately 990 miles from its confluence with the Ohio River at Cairo, Illinois, to the Gulf of Mexico.
Landscape: The region features a mix of alluvial plains, loessal bluffs, and coastal wetlands.

Unlike the upper sections, it has no locks or dams, but it is managed with levees and dikes to control flooding and maintain a navigable channel.
Flood Control: The Mississippi River and Tributaries Project includes levees, floodways, and spillways to manage flood risks and protect communities.
Ecosystems: The basin supports diverse ecosystems, including wetlands, bottomland hardwood forests, and a variety of aquatic habitats. These areas are vital for wildlife and provide important ecological services.

Agriculture: The fertile floodplains are used extensively for agriculture, producing crops like cotton, soybeans, and rice.
Recreation: The basin offers numerous recreational opportunities, including fishing, boating, and wildlife observation.
Water Supply: It provides water for millions of people and supports various industrial activities.

Habitat loss and water quality degradation are also significant concerns.
Infrastructure: Maintaining and upgrading the aging infrastructure, including levees and navigation channels, is a continuous challenge.
