Neuse River at Smithfield, North Carolina Flood Map Files from October 2016

These polygon boundaries, inundation extents, and depth rasters were created to provide an extent of flood inundation along the Neuse River within the community of Smithfield, North Carolina. The upstream and downstream reach extent is determined by the location of high-water marks, not extending the boundary far past the outermost high-water marks. In areas of uncertainty of flood extent

Shift Adjusted Ratings for Georgia, North and South Carolina Stream Gages

Use the URL below to view the shift-adjusted rating table for any USGS site. Stage-discharge relationships (ratings) are primarily developed from a graphical analysis of multiple streamflow measurements. 

Replace the ♦♦♦♦♦♦♦♦ with a USGS site number.
