      By Lower Mississippi-Gulf Water Science Center      December 13, 2016    

## Groundwater levels

### Water levels in the shallow aquifer have shown declines in recent years.

## MAP study area

## Irrigation in the delta

## Delta wildlife

The Mississippi Alluvial Plain is one of the most productive agricultural regions in the Nation and depends on groundwater for irrigation. The MAP area constitutes the third largest area of irrigated cropland in the United States. The area is approximately 29,000 square miles (19 million acres) and includes parts of the States of Missouri, Tennessee, Arkansas, Mississippi, and Louisiana.

The U.S. Geological Survey (USGS) Water Availability and Use Science Program (WAUSP) is supporting a regional groundwater availability study of the Mississippi Alluvial Plain (MAP) to provide stakeholders and managers information and tools to better understand and manage groundwater resources. The study focus is on quantifying the status of the groundwater system in the MAP and determining how groundwater resources respond to development.  Advanced characterization of the MAP, synthesis of field data, and numerical modeling will be used in the study.See more about the study here.
