Results of Sediment Investigation of Wyatt FadowLake

Dear Mr. Farlow�
After heavy storms on May 15, 2010 you contacted NCIDOT and NCDENIR about turbid water and silt
reaching your lake, We were aware nf the silt loss from the project and had notified the proper agencies
and our Roadside Environmental Unit \oinvestigate, The investigation revealed that recoverable silt did
migrate downstream from the project approximotg|y90Ofeet. The silt was removed by hand from the
stream to that point and the stream was monitored for possible accumulation of sift that could be removed
from the system. Minor amounts of silt were beyond this point, but the deposits were not enough to be
recovered. A logging operation that was upstream may have also contributed to the film of silt.
Very turbid water discolored your lake for several days on some occasions.
Dn October 25.20i8. the Beotevhnica Engineering Unit completed a pond sediment investigation atyour
property. Attached are the findings and observations uf the investigation. The sediment samples show
that all locations have less than half an inch of recent sediment thickness. /\ film ofsediment that iynot
retrievable did reach your lake.
|n conclusion, NCDOT has investigated the sediment hn your lake and conclude that a thin film did reach
your lake. It is improbable that the recent sediments observed in the samples collected from your lake
result from construction activities related to the WS-311 Bypass Project. Nn matter the source ufthe
sediment |n your lake, itim not feasible turemove the thin film oJ recent sediment. VVn will continue to
rnonitor the stream for retrievable deposits from the US-311 Bypass Project until it is stabilized.
