Subject Low-flow characteristics for unnamed tributary to South Prong Anderson Creek in Harnett County
Mr. Huysman,
Forwarded below are low-flow estimates provided in response to a recent request you made concerning an unnamed
tributary to South Prong Anderson Creek in Harnett County. In completing the estimates earlier this week, I requested the
development of an invoice for $250 that was to be attached at the end of this message.
Given the focus on preparations in anticipation of a possible federal government shutdown, the invoice has not been
developed. I will follow up with another email containing an invoice at a later date. In the meantime, the low-flow
estimates are being provided for your use and assessment as needed.
Thank you for your patience.

Dear Mr. Huysman,
In response to your inquiry about the low-flow characteristics for a location on an unnamed tributary to South Prong
Anderson Creek in Harnett County (station id 0210338840, drainage area 0.35 sqmi), the following information is
provided:
A check of the low-flow files here at the USGS North Carolina Water Science Center does not indicate a previous
determination of low-flow characteristics for the point of interest identified in your email dated March 4, 2011. No USGS
records of discharge are known to exist for your point of interest, and streamflow data is very limited in this part of Harnett
County.
There are records of miscellaneous measurements at a downstream USGS partial-record site on South Prong Anderson
Creek near Lillington (station id 02103390, drainage area 7.57 sqmi) in vicinity of your point of interest. However, all but
two of two of the measurements are crest-stage gage measurements used for flood-frequency analysis. The two
remaining low-flow measurements are both zero flow, made during the month of September in 1954 and 1968.
Where no or insufficient data is available for a low-flow analysis, a determination of low-flow characteristics is based on
assessment of low-flow yields at nearby locations where such statistics have previously been determined. The low-flow
characteristics that are provided have been computed by correlating the runoff characteristics of a nearby stream in
vicinity of the request site.
Please note the flow estimates do not account for the presence of any diversions or regulation, present or future, which
may occur upstream of the request site.
Previously published low-flow information for streams in your area of interest...
The most recent low-flow information published for streams in Harnett County is in a basinwide low-flow report completed
in 2001. It is USGS Water-Resources Investigations Report 01-4094, "Low-flow characteristics and discharge profiles for
selected streams in the Cape Fear River Basin, North Carolina, through 1998 " (Weaver and Pope, 2001). An online
version of the report is available through http://nc.water.usgs.gov/reports/wriO14094/. The report provides the low-flow
characteristics (based on data through 1998) for continuous-record gaging stations and partial-record sites within the
Cape Fear basin. The report also provides low-flow discharge profiles (7Q10, 30Q2, winter 7Q10, and 7Q2) for the Cape
Fear River and selected tributaries within the basin.
Considering the above information, please be aware of the following: The data provided in the above referenced report
are based on periods of record ending in advance of the drought conditions that have occurred since publication of the
report. In some North Carolina basins, the low-flow conditions observed during the recent droughts (1998-2002, 2007-09,
2010-11) have resulted in lower low-flow statistics. No formal statewide investigation has been completed to document
the changes in low-flow statistics since the droughts. However, where updated analyses have been completed for
selected stations, the changes in pre-drought versus updated 7Q10 discharges have shown varying percentage changes
of decline. For instance, at a nearby long-term continuous-record gaging station on Flat Creek near Inverness in Hoke
County (station id 02102908, drainage area 7.63 sqmi, records since June 1968), the 7Q10 declined about 31 percent
between the 1998 and 2010 climatic years.
Note: The climatic year is the standard annual period used for low-flow analyses at continuous-record gaging stations. It
runs from April 1 through March 31 and is designated by the year in which the period begins. For example, the 2010
climatic year is from April 1, 2010, through March 31, 2011.
Several pieces of information to consider...
(1) A drainage area of 0.35 sqmi was determined for your point of interest on the tributary to South Prong Anderson
Creek.
(2) Streamflow data and, correspondingly, low-flow characteristics that would be based on such data are very limited in
your area of interest. In Table 1 of the above referenced report, there are three nearby sites in vicinity of your point of
interest for which low-flow discharge estimates are provided. Expressing these estimates as low-flow yields (again, flow
per square mile of drainage area, or cfsm) provides some indication of the yield ranges that could potentially be applicable
to your point of interest. The 7Q10 low-flow yield range is from about 0.01 to 0.10 cfsm (with an average of about 0.07
cfsm). The 30Q2 low-flow yield range is from about 0.10 to about 0.33 cfsm (with an average of about 0.23 cfsm).
(3) As plotted on Plate 1 of the above referenced report, the Anderson Creek basin is located across the boundary
between Hydrologic Areas 3 (Sand Hills) and Hydrologic Areas 1 and 2 (Coastal Plain sandy and clay soils). There are
regional low-flow relations available for HA3, but none available for HA1 and HA2. While the basin for your point of
interest appears to be within HA3, the occurrence of two historical discharge measurements at zero flow raises some
question as to the exact nature of the soils in the basin.
(4) Mean annual runoff for streams in this area is mapped in the above referenced report as being approximately 1.2 to
1.3 cfsm.
Putting together the above pieces of information...
Applying the above ranges in low-flow yields (in item #2) to a drainage area of 0.35 sqmi results in following low-flow
estimates:
7Q10 = 0 to 0.04 cfs (average 0.02 cfs) ==> use zero flow (see comment below)
30Q2 = 0.04 to 0.12 cfs (average 0.08 cfs)
Applying the yield for mean annual runoff (item #4) to the drainage area results in an estimated average discharge of
about 0.4 to 0.45 cfs.
Given the very low range in estimated 7Q10 discharge combined with (1) recognition of the two historical measurements
at zero flow at the downstream partial-record site and (2) recognition of the declines in low-flow statistics following the
recent drought episodes, it is my judgment that the appropriate 7Q10 estimate for your point of interest is very likely zero
flow.
A charge of $250.00 for accessing and processing information has been assessed to partially offset these costs. An
electronic invoice covering processing costs for these data is attached to this email as a PDF file. Instructions for
sending your payment are shown on the invoice.
This information is considered preliminary and subject to revision pending further analysis as further data were to become
available, and is made available through our cooperative program of water-resources investigations with the North
Carolina Department of Environment and Natural Resources.
Hope this information is helpful. If you have any questions regarding this information, please contact me at the phone

Thank you.

Subject: Initial USGS response concerning low-flow inquiry ... Re: 7Q10 Request, UT South Prong Anderson Creek,
Harnett County, NC
Chris,
In response to your inquiry about the flow statistics (7Q10, mean annual flow) for a location on an unnamed tributary to
South Prong Anderson Creek in Harnett County, the following initial response is provided:
A check of the low-flow files here at the USGS North Carolina Water Science Center does not reveal any previous
determination for your point of interest. A rough delineation of the drainage basin (using mapping software) upstream
from your point of interest indicates the drainage area to be in range of 0.3 to 0.4 sqmi.
A preliminary assessment of available information at nearby locations where low-flow estimates were published in a
basinwide low-flow report for the Cape Fear River basin (Weaver and Pope, 2001; available online at
http://nc.water.usgs.gov/reports/wri014094/) leads me to believe a 7Q10 estimate for your point of interest is likely zero
flow.
The mean annual flow yield for this area is estimated between 1.2 and 1.3 cubic feet per square mile drainage area
(cfsm). Once a more firm drainage area is determined, it can be applied to this yield range to estimate the mean annual
flow. The yield values were obtained from plate 2 included in a statewide low-flow report by Giese and Mason (1993,
available online at
http://pubs.er.usgs.gov/#search:advance/page=1/page size=100/series cd=WSP/report number=24030).
Please understand this information is based on a preliminary assessment. Further analyses are needed to confirm the
initial assessment, and a fee of $250 per site is required for completion of a more in-depth assessment and formal
determination of estimates. If you want us to complete a more in-depth assessment, please let me know and we'll
proceed from there. The assessment would be completed within four weeks, and the response would be made via email
with an invoice attached to the email message.
Hope this information is helpful. Please call if you have questions.
Thank you.
