A plan of stream flow measurement for Briarwood Subdivision
(Briarwood) was submitted August ivis�.©n

approved by Noco Division of Environmental Management by
letter dated September 2 19930

BRUSHY FORK CREEK
Whereas USGS does not maintain a gauging station on
unnamed Sri butar to g g this
YBrushy Fork Creek, determination of
7Q10 flow is based on comparison of flow measurements
at the tributaryto the results�s made
from USGS gauging station
No. 02114450 on Little Yadkin River. The results
were plotted on a graph (FIGUREof each
g p 1) and a best fit line was
constructed through the corresponding data points.
the 7Q10The
value represenLing flow of the USGS gauging station
was extended from its axis. The best fit line was extended
points until
thru the data
it intersected with the extended
7Q10 flow value for the gauging station. At this
point, the
intersection coordinate was ex
tended to the axis for the
tributary to ascertain the projected 7Q10 flow. 201 DATA COLLECTION
Flow measurements were taken on the tributaryas '
in the approved prescribed
pp procedures. Measurements were made by
constricting flow thru a pipe and then
p collecting the flow
in a container. Each measurement consisted
of measuring the
amount of flow colle
cted (gallons) in a fifteen (15) second
interval.
Due to the timing of the initiation of flow measurements
relative to the need to collect
c� measurements as quickly as
practical during the more preferable period of the he year
(fall), measurements
were taken as soon as a suitable period
of no precipitation occurred and made dailywhile while these
conditions persisted. In so doing, five (5) measurements
were obtained by mid -November and should be indicative of
base flow conditions.
Measurements on each day were repeated a minimum
(3) times and the average of three
g was recorded as the result.

For information purposes, a reading was made of the
instantaneous
gauge level at the USGS station® A ' was made to record the measurement video tape

Dear Mr. Horne:
September 2, 1993
Subject: Proposed Plan of Stream Flow Measurement
Briarwood Subdivision NC0028746
Stokes County
The stream flow measurement plan submitted has been reviewed by the Technical
Support Branch and a simple change in the methodology proposed would be requested. The
plan calls for the use of a five gallon bucket as a measuring device. Tom Zembrzuski, [USGS
pointed out that, 1 duringthe measurement period(s)]
the stream flow is similar to that portrayed in
the pictures attached to this report, these buckets will fill up too fast for an accurate measurement.
The general time frame required for an accurate measurement needs to be from ten to fifteen,
(10-15) seconds. In other words, a container more in the vicinity of twenty-five (25) gallons would
be appropriate. The only other item(s) requiring comment were two technical problems that can
be easily remedied by an amendment letter form you; (1) submission of the final results
calculations, extrapolations, etc. need to be sent to: '
Donald L. Safrit, P.E.
Assistant Chief for Technical Support
Division of Environmental Management
Water Quality Section
PO Box 29535
Raleigh, NC 27626-0535
and (2), the calculations, [page 3] for Average Measurement (gal/sec) = 5 gallons / T(sec) should not be
5
divided by five. The calculation for Average measurement (gal/sec) should read as follows:
(# buckets * 5) / total seconds.
After discussing this plan with Tom Zembrzuski and Robert Mason, [USGS] the Technical
Support Branch will concur with their assessments of this plan. It was at Robert Mason's
suggestion that you take pictures of the site for verification. Mason also suggested that a video
recording of the measurement process be taken for further documentation. The Technical
P.O. Box 29535, Raleigh, North Carolina 27626-0535 Telephone [phone] FAX [phone]
An Equal Opportunrty Affirmative Action Employer 50% recycled/ 10% post -consumer paper

Support Branch feels this is a valid solution to any documentlion problems which may arise
during this process.
The use of a pipe as a release to this dam was discussed with Mr. Mason. He felt that it
would be appropriate to insert a pipe at the bottom of the stream dam to create a 'drop' of the
release for placement of the container to take measurements. Mr. Mason's understanding of this
set up was that leakage could occur around the insertion point of this pipe; if anything, this would
lead to more conservative measurement.
Because of current weather conditions, (i.e. lack of rain for an extended period of time) it
is imperative to begin this study immediately. The report implies these measurements will be
taken sometime in September or October, but immediate implementation would derive more
representative results. The Division of Fnvironmental Management will need documentation as to
what changes will be made in the submitted plan, (i.e. the size of measuring container you will use,
will this process be taped on video, and what Average Measurement (gal/sec) formula will you
use).
If you require any more information on this matter, please contact Mr. Farrell Keough at
[phone].
