annual runoff forthe entire Neuse River Basin upstream from Kinston for the period 1983-99 (the period after the com- pletion of Falls Dam) was about 14 inches. 40,000 - Falls (site 20) - Clayton (site 221 35,000 - Goldsboro (site 27) - Kinston (site 281 Cl 30,000 z 0 ~ ~ ~ 25,000 ~ ii520,OOO ~ u " ~ 15,000 "' ~ u ~ is 10,000 5,000 0 10 15 20 25 301 10 SEPTEMBER 1999 Flooding was much less widespread in the Cape Fear River Basin than in the Tar-Pamlico and Neuse River Basins, The most 31 severe flooding occurred near Wilmington and along the Black and Northeast Cape Fear Rivers, near the location where Hurricane Floyd made landfall. New maximum water-level records were established on Hood Creek (site 41), Blaek River (site 42), and Northeast Cape Fear River (site 43), and flood recurrence intervals at those sites were between 100 and in excess of500 years (table 3). On the Northeast Cape Fear River, the September 1999 maximum water level exceeded the previous record by almost 3.4 feet, and the peak flow was 50 percent !,'feater than the previously recorded peak flow, which occurred in 1962 (table 3). 15 OCTOBER 20 Cape Fear River Basin 25 Figure 10. Streamfiow in the Neuse River at four locations between Falls Dam and Kinston, September-October 1999, Dam to the total flow at Goldsboro and Kinston was less than might be expected if the Neuse River were unregulated and if contributions to streamflow were proportional to drainage area. Another way to express the differ- ence between flow contributions from the upper N euse River Basin and the basin downstream from Falls Dam is in equivalent inches of runolT. The flow from Falls Dam during September was equivalent to 1.9 inches of run- off from the 772-mi2 drainage basin upstream from the dam. The runoff from the 1,920-mi2 portion of the Neuse Basin between Falls Dam and Kinston during September was 8.5 inches. In comparison, the average Neuse River flooding in Goldsboro, N.C.

Two Months of Flooding in Eastern North Carolina, Septcmbcr-Qctobcr 1999 Other River Basins The number of streamgages in northeastern North Carolina is small relative to those in the Tar-Pamlico and Neuse River Basins, so the extent and magnitude of flooding in that region is not as easily determined.
