<br />Figure 9. Stage hydrographs for the Neuse River at Kinston, September-October
<br />1999, and near Goldsboro. September-October 1996 and 1999,
<br />
<br />at Goldsboro (site 27, fig. 7) from
<br />September 7 until the end of October,
<br />and the water level at Kinston (site
<br />28, fig, 7) was still 1.5 feet above
<br />flood stage at the end of October,
<br />There are 16 USGS streamgaging
<br />stations in the Neuse River Basin
<br />downstream from and including
<br />Clayton (site 22, fig. 7); not all sites
<br />are included in table 3 and figure 7.
<br />New records for maximum water
<br />levels were established at 14 of the
<br />16 sites, except at Swift Creek (site
<br />24) and Middle Creek (site 25),
<br />which are the westernmost of the
<br />16 gages. This means that, with the
<br />
<br />River (site 33); maximum water
<br />levels recorded at these sites
<br />exceeded previously established
<br />maximum values by 2.6 feet (site 26,
<br />with 80 years of record) to almost
<br />7.2 feet at site 30, where more than
<br />40 years of streamflow data have
<br />been recorded (table 3),
<br />Contributions to streamflow Irom
<br />the upper Neuse Basin (upstream
<br />from Falls Dam) were small relative
<br />to contributions downstream
<br />from Clayton (fig. 10). During
<br />September, flow at Falls Dam
<br />accounted for about 10 percent
<br />of the total flow volume at
<br />Goldsboro and about 8 percent
<br />of the lotal monthly flow vol-
<br />ume at Kinston, In contrast, the
<br />drainage area at Falls Dam
<br />represents about 32 percent of
<br />the total drainage area at Golds-
<br />boro and about 29 percent of the
<br />drainage area at Kinston. During
<br />October, the volume of water
<br />released Irom Falls Dam was
<br />equivalent to about 26 percent
<br />of the total flow volume at
<br />Goldsboro and about 22 percent
<br />of the total flow volume at
<br />31
<br />Kinston. Hence, in both Septem-
<br />ber and October, the volume of
<br />flow contributed by Falls
