Heavy rainfall occurred across Louisiana during March 8-19, 2016, as a result of a massive, slow-moving southward dip in the jet stream, which moved eastward across Mexico, then neared the Gulf Coast, funneling deep tropical moisture into parts of the Gulf States and the Mississippi River Valley. The storm caused major flooding in north-central and southeastern Louisiana. Digital flood-inundation maps for a 30-mile reach within the community of Slidell near the Pearl River in St. Tammany Parish, LA was created by the U.S. Geological Survey (USGS) in cooperation with Federal Emergency Management Agency (FEMA) to support response and recovery operations following a March 8-19, 2016 flood event. The inundation maps depict estimates of the areal extent and depth of flooding corresponding to 15 high-water marks (HWM) identified and surveyed by the USGS following the flood event.

The U.S. Geological Survey (USGS) documented the extent of flooding along a reach of the Pearl River through the metropolitan area of Jackson, Mississippi following the flood event of February 10-26, 2020. The event was a result of heavy precipitation over a 72-hour period combined with pre-existing saturated soil conditions in the upper portions of the Pearl River basin. USGS streamgages 02482000 Pearl River at Edinburg, MS and 02482550 Pearl River at Carthage, MS recorded 8.2 and 8.6 inches of precipitation respectively for the period of February 10-13. On February 17, the Pearl River crested at USGS streamgage 02486000 Pearl River at Jackson, MS at 36.67 feet (270.06 ft North American Vertical Datum of 1988) which was the highest peak since 1983 and fourth highest peak since record began in 1901. The USGS recovered and surveyed 72 high-watermarks along a 19-mile valley reach of the Pearl River in the Jackson area. This reach extended from the Ross Barnett Reservoir dam downstream to the city of Byram. These high-watermarks represent headwater flooding along the Pearl River main stem and backwater flooding along multiple tributaries. Peak elevations were also recorded at seven tributary hydrograph stations within the study reach. The high-watermark elevations were used to develop maps depicting the areal extent and depths of the flood. A water surface profile of this event was also compared to profiles documented following the April 1979 and May 1983 flood events. The file types contained in this data release include shapefiles, rasters, graphic (jpg), comma-separated values (csv) files, and metadata.

This map is one of 18 produced for the final open-file report: An Investigation of Potential Geothermal Energy Sources in Mississippi, DoE Contract No. EG-77-S-05-5361; Edwin E. Luper, Principal Investigator; Mississippi Geological, Economic and Topographical Survey; Jackson, Mississippi; 1978. Maps produced include areas of central and southern Mississippi, including all or portions of Adams, Amite, Attala, Calhoun, Carroll, Claiborne, Clarke, Copiah, Covington, Forrest, Franklin, George, Greene, Hancock, Harrison, Hinds, Holmes, Humphreys, Issaquena, Jackson, Jasper, Jefferson, Jefferson Davis, Jones, Lamar, Lauderdale, Lawrence, Leake, Leflore, Lincoln, Madison, Marion, Newton, Pearl River, Perry, Pike, Rankin, Scott, Sharkey, Simpson, Smith, Stone, Sunflower, Walthall, Warren, Washington, Wayne, Wilkinson, and Yazoo Counties. Each map is contoured along a single isothermal surface: Maps 1-A through 1-E: 158F (70C) Maps 2-A through 2-E: 212F (100C) Maps 3-A through 3-E: 248F (120C) Map 4: 302F (150C) Map 5: 356F (180C) Finally, a location map of the 401F (205C) isotherm well is labeled Map 6. Maps 1, 2 and 3 were constructed at approximate scale of 1:250,000. These were broken into 5 sections each. The remaining maps were constructed at approximate scale of 1:500,000. These maps were contoured manually by the staff of the MGS in 1978. Many of the reference marks appear to be incorrectly drawn, so a best-fit methodology was used on the scanned maps to attempt to place them in their appropriate relative location in georeferencing.

This lidar data was collected primarily for flood plain mapping within Pearl River County, MS. The data were processed into separate Bare Earth and First Surface products. The two were subsequently classified (bare earth and unclassified) and merged to create one data set. The data were collected from 1-8 Feb 2003. One flight was reflown on 30 March 2003.

An Investigation of Potential Geothermal Energy Sources in Mississippi, DOE Contract No. EG-77-S-05-5361; Edwin E. Luper, Principal Investigator; Mississippi Geological, Economic and Topographical Survey; Jackson, Mississippi; 1978. The objective of this study was to assess the geo-temperature regime in the subsurface of the south-central and southern portion of the state of Mississippi. The area includes the Mississippi Salt Basin, the Jackson Dome, and related minor structural features within the state. In order to accomplish the objective, it was necessary to accumulate sufficient data to construct isothermal maps on six temperatures.The geothermal gradient is expressed in degrees Fahrenheit per hundred feet of depth. Results of this study have indicated that there are areas in south and south-central Mississippi that are favorable for further development of the geothermal resource within the state. The assessment of the geo-temperature regime is the first step in the exploration process and serves to isolate the more prospective areas. The report 'Investigation of Potential Geothermal Energy Sources in Mississippi, Open File Report 1 '(PDF) comprises 35 pages, including maps and index map. For Convenience, the Index Map is reproduced as a separate file and is available as a PDF. This data was submitted by the Mississippi Department of Environmental Quality - Office of Geology and made available for distribution through the AASG National Geothermal Data System.Maps produced include areas of central and southern Mississippi, including all or portions of Adams, Amite, Attala, Calhoun, Carroll, Claiborne, Clarke, Copiah, Covington, Forrest, Franklin, George, Greene, Hancock, Harrison, Hinds, Holmes, Humphreys, Issaquena, Jackson, Jasper, Jefferson, Jefferson Davis, Jones, Lamar, Lauderdale, Lawrence, Leake, Leflore, Lincoln, Madison, Marion, Newton, Pearl River, Perry, Pike, Rankin, Scott, Sharkey, Simpson, Smith, Stone, Sunflower, Walthall, Warren, Washington, Wayne, Wilkinson, and Yazoo Counties. The isothermal maps that are included with this report have been labeled as follows - Map 1: 158 F (70 C) isotherm. Map 2: 212 F (100 C) isotherm. Map 3: 248 F (120 C) isotherm. Map 4: 302 F (150 C) isotherm. Map 5: 356 F (180 C) isotherm. Map 6: 401 F (205 C) isotherm. The first three isothermal maps were constructed using an approximate scale of 1 to 250,000. Due to their size, they were divided into five sections as shown on the Index Map. The two remaining isothermal maps, as well as the 401 F (205 C) location map, were constructed using an approximate scale of 1 to 500,000. These maps were contoured manually by the staff of the MGS in 1978. Many of the reference marks appear to be incorrectly drawn, so a best-fit methodology was used on the scanned maps to attempt to place them in their appropriate relative location in georeferencing.
