A major element of the USGS mission is the documentation of the extent and magnitude of extreme hydrologic events, like floods and droughts. The South Atlantic Water Science Center is a leader in monitoring extreme water conditions, from droughts and falling groundwater levels to floods and storm-tide surges to water-quality problems.

Rising floodwaters overtopping a local bridge. Charlotte-Mecklenburg Hydrologic Network
Date Published: July 6, 2017

The U.S. Geological Survey (USGS) has been collecting streamflow data in North Carolina for more than 100 years. In the Charlotte and Mecklenburg County area, a hydrologic data-collection network has been established to collect not only streamflow data but also rainfall data. In response to the floods of August 1995 and July 1997, the U.S. Geological Survey Cooperative Water Program and...

Date Published: May 20, 2017

Preventing flood hazards, such as the hurricane induced storm surge, from becoming human disasters requires an understanding of the relative risks floods pose to specific communities and knowledge of the processes by which flood waters rise, converge, and abate. Historically, hurricane-induced storm tides have been documented through measurement of high-water marks left on structures or...

September 2009 Flooding. Chattahoochee River near Whitesburg (02338000)
Date Published: February 8, 2017

Many days of continuous heavy rain in mid-September 2009 resulted in flooding in many parts of Georgia, especially in north Georgia and the Atlanta region. The rains produced streamflows of record proportions. rivers and streams had magnitudes so great that the odds of it happening were less than 0.2 percent in any given year. In other words, there was less than a 1 in 500 chance that parts of...

Tar River Basin Flood-Inundation Mapping Sites, N.C.
Date Published: February 1, 2017

The U.S. Geological Survey (USGS) has created flood-inundation maps for selected streamgage sites in North Carolina. These maps depict the approximate area that would be inundated at selected water levels, ranging from approximately top-of-bank to the maximum observed water level. The inundated areas depicted on these maps are approximate, and accuracy of the maps is a function of the accuracy...
