SPARROW, a modeling tool for the regional interpretation of water-quality monitoring data. The model relates in-stream water-quality measurements to spatially referenced characteristics of watersheds, including contaminant sources and factors influencing terrestrial and aquatic transport. SPARROW empirically estimates the origin and fate of contaminants in river networks and quantifies...
The U.S. Geological Survey (USGS) works closely with the Mississippi Department of Transportation (MDOT) to provide information to be used by the MDOT for economical and optimum design of highway-drainage structures. The MDOT spends millions of dollars annually for highway construction. Streamflow records, hydrologic analyses of basins, and hydraulic analyses of the flooding potential at...
The National Water-Quality Assessment (NAWQA) Program is designed to describe the status and trends in the quality of the Nation's surface-water and ground-water resources and to provide a sound understanding of the natural and human factors that affect the quality of these resources. As part of the program, investigations will be conducted in approximately 60 areas -- called study units...
The objective of the Mississippi water-use effort is to collect site-specific or aggregated water-use information to be used in studying and managing the water resources of our State, to store the information in a computerized data base, and to disseminate it to the public through reports and publications.
The USGS collects water-quality samples from about 25 wells (of an approximately 100-well network), annually in order to determine and evaluate the ground-water resources of Harrison County, Mississippi. Since 1997, water samples have been collected at selected wells screened in the Citronelle, Graham Ferry, Pascagoula, Hattiesburg, and Catahoula Sandstone aquifers and are analyzed for field...
Long-term water-level records are needed to evaluate the effects of climatic variations on the recharge to and discharge from the ground-water systems, to provide a data base from which to measure the effects of development, to assist in the prediction of future supplies, and to provide data for management of the resource.
The U.S. Geological Survey, in cooperation with the Mississippi Department of Environmental Quality, U.S. Department of Agriculture-Natural Resources Conservation Service, Mississippi Department of Transportation, U.S. Department of Agriculture-Forest Service, and the Mississippi Automated Resource INformation System developed a 1:24,000-scale Watershed Boundary Dataset for Mississippi...
Floods are the most common and widespread of all natural disasters in the United States and are the leading cause of weather related deaths. Advances in technology have improved warning systems and have helped to decrease the loss of life over the past 50 years. Several sources of information are available to citizens and public officials to help make timely decisions regarding flood awareness...
The National Water Information System (NWIS) web application provides access to surface-water, groundwater, water-quality, and water-use data collected at approximately 1.5 million sites across all 50 states.
The National Water Information System (NWIS) Mapper provides access to water-resources data at over 1.5 million sites across the U.S., including current and historical data. Users can search by site type, data type, site number, or place.
See Current Water Conditions for Mississippi using our new interactive map. Here you can find information on Groundwater, Surface Water and Water Quality.
The interactive sea-level rise visualization tool results from a collaborative effort between NOAA's Coastal Services Center, USGS WARC, and USGS Mississippi Water Science Center. The tool illustrates the scale of potential flooding, but not the exact location, and does not account for erosion, subsidence, sediment accretion, or future construction.
USGS data portray selected structures data, including the location and characteristics of manmade facilities. Characteristics consist of a structure's physical form (footprint), function, name, location, and detailed information about the structure. The types of structures collected are largely determined by the needs of the disaster planning and response and homeland security organizations.
Boundaries data or governmental units represent major civil areas including states, counties, Federal, and Native American lands, and incorporated places such as cities and towns.
The National Hydrography Dataset (NHD) and Watershed Boundary Dataset (WBD) are used to portray surface water on The National Map.
The USIEI is a comprehensive, nationwide listing of known high-accuracy topographic and bathymetric data for the United States and its territories. The project is a collaborative effort of the USGS and NOAA with contributions from other federal agencies. The inventory supports the 3D Elevation Program and the Integrated Ocean and Coastal Mapping effort. This resource is updated in Spring and Fall.
The 3DEP products and services available through The National Map consist of lidar point clouds (LPC), standard digital elevation models (DEMs) at various horizontal resolutions, elevation source and associated datasets, an elevation point query service and bulk point query service. All 3DEP products are available, free of charge and without use restrictions.
Orthoimagery data typically are high resolution aerial images that combine the visual attributes of an aerial photograph with the spatial accuracy and reliability of a planimetric map. The National Map offers public domain, 1-meter orthoimagery for the conterminous United States with many urban areas and other locations at 2-foot or finer resolution.
The National Map offers a collection of small-scale datasets, most of which are at 1:1,000,000. The National Map publishes two data collections at one million-scale: one for Global Map users and one for National Map users. In terms of vector geometry, the lines, points, and areas in these data collections are identical. The difference is in the attributes assigned to these features.
Consistent synthesis, integration, storage, and availability of fundamental data is critical to meeting the needs of USGS Science. We develop databases for hydrography, topography, invasive species, water resources, and many other datasets utilized by resource managers.

“From the mountains to the coast, the southeastern U.S. contains ecosystems that harbor incredible biodiversity. Many of those ecosystems are already highly at risk from urbanization and other human land-use change. Identifying the ecosystems at risk from climate change will help inform conservation and management to ensure we don’t lose that biodiversity.” (Jennifer Constanza, report author)
