The passage of Hurricane Matthew during October 7–9, 2016, resulted in heavy rainfall that caused major flooding.

The peak stages and streamflows that occurred following Hurricane Matthew are documented in a USGS Open-File report published in December 2016 by the USGS South Atlantic Water Science Center.

The heavy rains and storm surge Hurricane Matthew produced caused severe flooding in many parts of the south east, resulting in almost 40 peak flood records. As the flood waters continue to recede from some affected areas, the U. S. Geological Survey will continue its efforts to record this historic flooding. Click here to learn more about the work the USGS has completed for Hurricane Matthew.

Hydrologic characterization of Bushy Park Reservoir, South Carolina, 2013–15

The Bushy Park Reservoir is a relatively shallow impoundment in a semi-tropical climate and is the principal water supply for the 400,000 people of the city of Charleston, South Carolina, and the surrounding areas including the Bushy Park Industrial Complex. Although there is an adequate supply of freshwater in the reservoir, taste-and-odor water-...
