1. Detailed description of the site including existing site conditions and Aerial Site Map;
Physiography and Land Use
The Site is located in the Carolina Slate Belt portion of the Piedmont ecoregion of North Carolina. Regional
physiography is characterized by dissected, irregular plains with moderate to steep slopes and low to
moderate gradient streams over boulder and cobble-dominated substrate (Griffith et al. 2002). Onsite
elevations range from a high of 780 feet National Geodetic Vertical Datum (NGVD) at the upper reaches
of the Main Channel to a low of approximately 740 feet NGVD at the Site outfall (USGS Reidsville, North
Carolina 7.5-minute topographic quadrangle) (Figure 3, Appendix A).

The Site provides water quality functions to an approximately 0.4-square mile (270-acre) watershed at
the outfall (Figure 3, Appendix A). The watershed is dominated by pasture, agricultural land, and sparse
residential development along the outskirts of Reidsville. Impervious surfaces account for less than 5
percent of the upstream watershed land surface.

Land use at the Site is characterized by livestock pasture, hay fields, and disturbed forest. Livestock have
unrestricted access to Site streams. A narrow riparian fringe has developed on the stream margins that
is composed of opportunistic species, invasive species, and a few mature tree species.

Water Quality
The Site is located within the Cape Fear River Basin in United States Geological Services (USGS) 14-digit
HUC 03030002010010 and North Carolina Division of Water Resources (NCDWR) Subbasin 03-06-01. Site
hydrology drains to Unnamed Tributaries to Lake Hunt (Stream Index Number 16-2-2-(1)), which has been
assigned a Best Usage Classification of WS-III, B; NSW (NCDWR 2013). Water Supply III (WS-III) are waters
used as sources of water supply for drinking, culinary, or food processing purposes where a more
protective WS-I or –II classification is not feasible. These waters are also protected for Class C uses and
are generally in low to moderately developed watersheds. Streams with a Class B designation are
protected for all Class C uses including aquatic life propagation and survival, fishing, wildlife, secondary
recreation, and agriculture, in addition to primary recreation. Primary recreational activities include
swimming, skin diving, water sking, and similar uses involving human body contact with waters on an
organized or frequent basis. The designation NSW (Nutrient Sensitive Waters) includes areas with water
quality problems associated with excessive plant growth resulting from nutrient enrichment.

The North Carolina Department of Environment Quality (NCDEQ) has assembled a list of impaired
waterbodies according to the Clean Water Act Section 303(d) and 40 CFR 130.7, which is a comprehensive
public accounting of all impaired waterbodies. An impaired waterbody is one that does not meet water
quality standards including designated uses, numeric and narrative criteria, and anti-degradation
requirements defined in 40 CFR 131. The unnamed tributaries to Lake Hunt that Site hydrology drains to
is not listed on the NCDENR draft 2016 or final 2014 303(d) lists (NCDEQ 2014, NCDEQ 2016).

Soils and Land Form
Based on Web Soil Survey mapping (USDA 2016), the Site contains six soil series as follows (Figure 4,
Appendix A).

Table 2. Site Soils
Map Unit
Symbol
Map Unit Name
(Classification) Hydric Status Description
CgB2 Clifford sandy clay loam
(Typic Kanhapludults) Non-hydric
This series consists of well-drained, moderately
eroded soils found along 2-8 percent slopes. The
parent material is saprolite derived from schist
and/or gneiss.
CsA Codorus loam
(Fluvaquentic Dystrudepts) Non-hydric
This series consists of moderately well-drained
and somewhat poorly drained soils found on 0-2
percent slopes in floodplains. The parent
material is alluvium derived from schist, gneiss,
phyllite, and other metamorphic rocks.
DcB Davie sandy loam
(Aquultic Hapludalfs) Non-hydric
This series consists of somewhat poorly-drained
soils found along 2-8 percent slopes. The parent
material is residuum from intermediate or mafic
metamorphic or igneous rock.
FrE2 Fairview-Poplar complex
(Typic Kanhapludults) Non-hydric
This series consists of well-drained, moderately
eroded soils found on 15-25 percent hill slopes
on ridges. The parent material is saprolite
derived from schist and/or gneiss.
NaB Nathalie sandy loam
(Typic Fragiudults) Non-hydric
This series consists of well-drained soils found
along 2-8 percent slopes. The parent material is
residuum from felsic igneous or metamorphic
rock.
PpD2 Poplar Forest sandy clay loam
(Typic Kanhapludults) Non-hydric
This series consists of well-drained soils found
along 8-15 percent slopes. The parent material is
residuum from felsic or intermediate, high-grade
metamorphic or igneous rocks high in mica
content.

Existing wetlands and drained hydric soils were delineated by a licensed soil scientist (NC LSS # 1233);
results of the delineation are depicted on Figure 4 (Appendix A) and the Site includes approximately 0.69
acres of disturbed wetland and 0.96 acres of drained hydric soils. A soil boring log is included in
Appendix B.

1.2.2 Stream Characterization
Stream geometry and substrate data have been evaluated to orient stream restoration based on a
classification utilizing fluvial geomorphic principles (Rosgen 1996). This classification stratifies streams
into comparable groups based on pattern, dimension, profile, and substrate characteristics. Primary
components of the classification include degree of entrenchment, width-depth ratio, sinuosity, and
channel slope.

Cross-sectional measurements were utilized to characterize existing stream channel conditions. The
location of each cross-section is depicted in Figure 4 (Appendix A). Cross-sectional data indicate that Site
streams accessed by livestock are downcutting and eroding laterally. The channels are characterized by
incised (G-type and Ge-type) channels with bank-height ratios ranging from 2.3 to 3.1 (data is presented

in Figure 4, Appendix A and Table 3). Channel impacts have resulted in little to no riffle-pool morphology,
disturbed instream habitat (lack of gravel and cobble substrate), oversized channel cross-sectional areas
(existing channels are 3 to 6 times the bankfull channel cross-sectional area), and an inability to access
Site floodplains during overbank events (Table 3).
