Here you will find maps created by Lower Mississippi-Gulf scientists that lend visual identity to our data. The maps you find in this section were devised by our scientists using Geographic Information Systems (GIS) that help us interpret the data through spatial and geographic imagery.

The Mobile River Basin in Alabama, Georgia, Mississippi, and Tennessee is one of the 59 study units that are part of the U.S. Geological Survey's National Water-Quality Assessment (NAWQA) Program.
June 1 marks the beginning of hurricane season. Should storms arrive on the Louisiana coast, the people in coastal communities across the State, along with many Federal, State, and local agencies will need to know how the storms are affecting the coastal and low-lying areas.The USGS maintains an extensive network of coastal gages that provides critical time-sensitive water level.

As part of their mission to protect public health and aquatic ecosystems, Alabama state agencies need accurate and representative streamflow statistics to establish realistic and applicable criteria for both water quality and water quantity (fig. 1).
The Arkansas Groundwater - Quality Network is a web map interface that provides rapid access to the U.S. Geological Survey's (USGS) NWIS and the U.S. Environmental Protection Agency's (EPA) STORET databases of ambient groundwater information. The interface enables users to perform simple graphical analysis and download selected water-quality data.
Beta version 4 is now available for most states on a trial basis, and version 3 remains available. Beta version 4 provides a single user interface (at http://streamstatsags.cr.usgs.gov/streamstats/) for all states that are implemented, rather than separate applications for each state, as in versions 2 and 3, and the user interface is more user friendly than previous versions.
StreamStats is a Web-based tool that provides streamflow statistics, drainage-basin characteristics, and other information for USGS streamgaging stations and for user-selected ungaged sites on streams. When users select the location of a streamgaging station, StreamStats provides previously published information from a database. When users select a site on an ungaged stream,
Static flood-inundation map libraries consist of maps that have been created in advance of a flood that are ready to be served through the Internet. Each library consists of a set of flood extent and depth maps developed for predetermined stream stage intervals (for example, a map for each one foot of stage).
