ATTENTION. Mr. Marl E. Ray
Gentlenem
This 3s in responee.to Yam' letter of January 5, 1973 by chioh you
supplied your Report port on Investigation of Wiggins Mill Dam and Fla tausei
with plans showing proposed repair work (as wall as data on the proposed
BuCkhorn water supply dam) , for approval under Sec. 11 .215.27 of tiro Jam
Safety Law of 1967. Affected State agenciee have been consulted, and the
pleel have been reviewed.
Your plan includes provision for re1easfxk; flows to maintain the 7-day
1O yeax° minimum at all times, as is requirod b; the lair. The dater Q w1ity
Division of this Office advises that this required minimum flow is 2.0 cf's .
Your plensl are satisfactory =der the requirements of the Dam Safety
Law and this letter constitutes the approval required by that law. You
advise that no time has as yet been set for the commencement and completion.
of the work; ply Furnish them when they do become available.
Sincerely ,

Dear Er. Ray:

November 19, 1971 .
This letter is to confirm our estimates of stream. low for several sites

These estimates are based :..ors discharge measurements made during -the

discharge records since 1964, at station 2-903.3, Contentnea Creek -near
Luca= (at Bu h rn dam site), and records from nearby. long-term gaging
stations. ``" 1 3 : , »;
During our phone conversation, Mr. Barlow meaticned that a figure of 7
cfs had been used by others as the 7-day, 10-year minimum at or near
your point of interest at NC 581. We can only surmise that this figure
was based on the 7--day, 10-year flow of 0.043 cfsm shown for Coatentuea
Creek at Hookerton or. page. 103 of WSP 1761. The drainage area -Of 729
atuare miles at Hookerton is several times as large as the drainage='ar•ea
at your .points of interest. Available records indicatethat the area
between your pointsof i.cterest and the Hookerton gage is 3enera11y

thus the data as outlined previously, per force overrode the :iookertoa
data.

It is hoped that the above data will met your planning and design needs
for the proposed Wilson r,,ater supply.
For the District Chief, Ralph C. Heath..
