Smith Creek Watershed Restoration Plan (May 2008) 1
EXECUTIVE SUMMARY
The Smith Creek Watershed is 34,500 acres and is located in Warren County, North Carolina.
The Smith Creek Watershed is part of the larger Roanoke River Basin.
Agriculture is the main pollution source that this project aims to address. The nonpoint source
pollutants that are targeted in this effort include: excess nitrogen, excess phosphorus,
sedimentation, pathogens/bacteria and low dissolved oxygen.
The primary objective of this project is to develop and implement a watershed restoration plan to
address the severe sedimentation problems of Smith Creek, in the Roanoke River Basin. The
Smith Creek Agriculture Sediment Initiative will restore degraded waters by targeting and
implementing best management practices (BMPs). The BMPs will directly reduce sediment
delivery to the listed impaired waters. Other benefits can be expected as well since many of the
proposed BMPs will prevent off-site movement of pesticides, phosphorus, nitrogen, and fecal
coliform. Improvements in streambank stability and habitat for fish and macroinvertebrates will
also be realized. Smith Creek is listed on North Carolina’s 2002, 2004 and 2006 303(d) lists
because of biological impairment and low dissolved oxygen. Erosion and sedimentation from
agriculture has been identified as the potential source of impairment. The overall goal is
removing Smith Creek from the NC 303(d) list.
The Division of Soil and Water Conservation and the Warren Soil and Water Conservation
District developed and are implementing a watershed restoration plan for Smith Creek. This
plan addresses the nine key elements required by U.S. EPA. The project will identify and
prioritize sites to accelerate BMP implementation in Smith Creek, using Section 319 funds to
supplement ACSP funds targeted by the Soil and Water Conservation Commission (SWCC).
The Smith Creek Agricultural Sediment Initiative will address the severe sedimentation
problems found in Smith Creek by installing necessary best management practices on
agricultural sites. These practices include but are not limited to field borders, grassed waterways,
livestock exclusion, heavy use area protection, long term no till, and sod based rotation. Warren
Soil and Water Conservation District and the DSWC will prioritize the necessary BMPs that are
needed to prevent further water quality degradation from nonpoint source pollutants.
An estimated 6,000-ton reduction of sediment is expected from the implementation of Best
Management Practices (BMPs) within the Smith Creek Watershed. The majority of this
reduction will be from implementing sediment reducing agronomic farming practices such as
long-term no-till and sod based rotation. Vegetative and structural BMPs, such as field borders,
grassed waterways, and heavy use protection areas will also play a vital role in reducing the
amount of sedimentation entering into the creek and its tributaries. Such sediment controls can
repair gulley erosion that may be occurring at the edge of the agricultural field.
Implementation of livestock exclusion practices will also be a vital component of the success of
this project. BMPs installed on sites where cattle have been allowed access to the streams may
show the most benefits to water quality in the shortest timeframe. Excluding animals from the
creek and repairing the streambanks with native vegetation and additional engineering work, as
necessary, should decrease the levels of turbidity at the previous sample sites.
Smith Creek Watershed Restoration Plan (May 2008) 2
The overall goal of the community education program in the Smith Creek watershed is to
develop an atmosphere that encourages long-term protection and improvement of water
resources in the watershed (see Appendix E for a copy of the educational brochures).
Various educational opportunities will be included within the implementation phase of the
project that will include the following objectives:
• Increase public awareness of the value of clean water
• Increase public awareness of how common activities contribute to nonpoint source
pollution and poor water quality
• Increase public awareness of how conservation practices can reduce negative impacts on
water quality and habitat degradation
• Increase public awareness of how the protection of water quality can contribute to the
environmental and economic benefits of the watershed.
Estimated technical assistance that will be needed to effectively implement this project is
$32,625. However the Warren SWCD is providing their services without reimbursement to
implement this project. An additional $108,000 will be needed to assist landowners in installing
BMPs on priority sites. The Warren SWCD has placed this watershed as a priority on their NC
Agriculture Cost Share Strategy Plan. A total of $130,000 was requested to adequately fund the
Smith Creek Agricultural Sediment Initiative and was awarded via the Section 319 Program
beginning FY06 (July 15, 2005).
It is estimated that additional funding in excess of $130,000 is needed to implement conservation
measures throughout the Smith Creek watershed in order to continue to work towards addressing
the nonpoint source pollution concerns and to ultimately remove Smith Creek from the North
Carolina 303(d) list.
Smith Creek Watershed Restoration Plan (May 2008) 3
INTRODUCTION
The Smith Creek Watershed is 34,500 acres and is located in Warren County, North Carolina.
The Smith Creek Watershed is part of the larger Roanoke River Basin.
Agriculture is the main pollution source
that this project aims to address. The
nonpoint source pollutants that are
targeted in this effort include: excess
nitrogen, excess phosphorus,
sedimentation, pathogens/bacteria and low
dissolved oxygen.
The estimated load reduction from
implementing this project is 14,000
pounds of nitrogen saved, 8,800 pounds of
phosphorus saved, and 3,500 tons of soil
saved. The estimated load reduction
calculations were derived from several
methods such as Revised Universal Soil
Loss Equation, North Carolina
Agricultural Nutrient Assessment Tool,
Nitrogen Loss Estimation Worksheet and
other approved erosion reduction
equations.
The primary objective of this project was to develop and implement a watershed restoration plan
to address the severe sedimentation problems of Smith Creek, in the Roanoke River Basin. The
Smith Creek Agriculture Sediment Initiative will restore degraded waters by targeting and
implementing best management practices (BMPs). The BMPs will directly reduce sediment
delivery to the listed impaired waters. Other benefits can be expected as well since many of the
proposed BMPs will prevent off-site movement of pesticides, phosphorus, nitrogen, and fecal
coliform. Improvements in streambank stability and habitat for fish and macroinvertebrates will
also be realized. Smith Creek is listed on North Carolina’s 2002, 2004 and 2006 303(d) lists
because of biological impairment and low dissolved oxygen. Erosion and sedimentation from
agriculture has been identified as the potential source of impairment. The overall goal is
removing Smith Creek from the NC 303(d) list.
The Warren County Soil and Water Conservation District (SWCD) and the USDA-NRCS staff
are providing technical information, engineering assistance, and oversight of the installation of
the BMPs. The Division of Soil and Water Conservation (DSWC) worked with the district using
the NC Agriculture Cost Share Program (ACSP) infrastructure for financial assistance.
The state’s 303(d) list denotes many streams in North Carolina as being impaired by sediment
from agricultural sources. Beginning in 2000, the North Carolina Association of Soil and Water
Conservation Districts (NCASWCD) and the Soil and Water Conservation Commission (SWCC)
Figure 1: Smith Creek Watershed Location Map
Smith Creek Watershed Restoration Plan (May 2008) 4
began the Agricultural Sediment Initiative to target more than 50 stream segments on the 303(d)
list to implement agricultural BMPs to address this water quality concern. The SWCC has
targeted more than $1,000,000 to these streams, and Section 319 and Clean Water Management
Trust Fund grants have supplemented Commission allocations in Brasstown Creek (Clay and
Cherokee Counties), Ararat River (Surry County), Little Troublesome Creek (Rockingham
County), Haw River (Alamance County), and Contentnea Creek (Pitt, Greene, and Lenoir
Counties).
According to the 2001 Roanoke River Basinwide Water Quality Plan and the 2002, 2004 and
2006 NC 303(d) Impaired Waters Lists, Smith Creek is biologically impaired, and it is also
impaired due to low dissolved oxygen. Erosion and sedimentation from agriculture was
identified as being the potential source for the impairment. Corrective action is needed to
achieve the goal of ultimately removing Smith Creek from the NC 303(d) list.
The Division of Water Quality (DWQ) 2001 Roanoke River Basinwide Water Quality Plan
stressed the need for restoration work and corrective action in the Smith Creek Watershed.
Nonpoint source pollution has been identified as the contributor of most of the negative impacts
on the creek. The Basinwide Plan suggests that an increase of voluntary BMPs need to be
implemented on agricultural lands prior to substantial improvements in water quality being
detected. The NC ACSP as well as federally funded programs are continually being utilized
throughout Warren County. However the local priority for these programs has been placed on
the Tar-Pamlico River Basin because of the 30% Nitrogen Reduction Requirement from
Agriculture. Thus, adequate financial support to assist farmers in the installation of BMPs to
address the extensive sedimentation problems in the Smith Creek Watershed has not been
available.
The Division of Water Quality 2006 Roanoke River Basinwide Water Quality Plan states that
water quality in the Smith Creek watershed is expected to improve by the end of the next
assessment period (August 2009), due to the many efforts from the Warren County SWCD in
implementing projects in this watershed. In March 2005, Warren SWCD received an EPA
Section 319 grant totaling over $48,000 to restore Smith Creek by targeting nonpoint source
pollution and implementing BMPs. In addition, Warren SWCD was granted additional funding
of approximately $150,000 to carry out their projects in the Smith Creek watershed. This
Watershed Restoration Plan is part of the larger project that also includes educational efforts and
the implementation of agricultural BMPs.
PROJECT DESCRIPTION
The Division of Soil and Water Conservation and Warren Soil and Water Conservation District
developed and are implementing a watershed restoration plan for Smith Creek. The project will
identify and prioritize sites to accelerate BMP implementation in Smith Creek, using Section 319
funds to supplement ACSP funds targeted by the SWCC. The Smith Creek Agricultural
Sediment Initiative will address the severe sedimentation problems found in Smith Creek by
installing necessary best management practices on agricultural sites. These practices include but
are not limited to field borders, grassed waterways, livestock exclusion, heavy use area
Smith Creek Watershed Restoration Plan (May 2008) 5
protection, long term no till, and sod based rotation. Warren Soil and Water Conservation
District will prioritize the necessary BMPs that are needed to prevent further water quality
degradation from nonpoint source pollutants.
The NC Association of Soil and Water Conservation Districts, the Soil and Water Conservation
Commission and the DSWC are committed to and believe the Smith Creek Agricultural
Sediment Initiative will directly reduce sediment delivery to the targeted impaired stream. It will
also reduce nitrogen and phosphorus losses, fecal coliform delivery, and pesticides.
The Division of Soil and Water Conservation as well as the Warren Soil and Water Conservation
District understand the importance of addressing all nonpoint source contributors within the
watershed. Therefore an education and outreach program will be conducted for the residents of
the area including the community of Norlina. Brochures were developed and distributed that
focus on fertilizer application on home gardens and lawns and septic tank maintenance. This
method of outreach provides the residents ample information regarding the watershed in which
they live and the importance of keeping it clean. Contact information for local agencies that can
provide further technical assistance for their individual needs will also be provided.
MONITORING AND DATA COLLECTION
Monitoring will be conducted with cooperation between the Division of Soil and Water
Conservation, Warren Soil and Water Conservation District (SWCD) and the Environmental
Sciences Section (ESS) of Division of Water Quality. ESS conducted monitoring prior to BMP
implementation to establish a baseline. This initial data will serve as the point in which we will
be able to document changes before and after the final stages of the project.
Benthic macroinvertebrate surveys were conducted in the summer of 2004, thus this information
can be utilized as the baseline for this measure. The next scheduled benthic macroinvertebrate
survey is to be conducted in 2009. All data collected will be shared with the DWQ’s Planning
Branch in order to assist them with their Basinwide Planning initiatives.
The Warren SWCD will be conducting field assessments as well. These calculations will
estimate the reduction in soil loss and nutrient loss using the North Carolina Agricultural
Nutrient Assessment Tool and the Revised Universal Soil Loss Equation.
The Division of Soil and Water Conservation will be meeting with the Division of Water Quality
to develop a plan for monitoring for the Spring of 2009 and beyond.

PUBLIC INVOLVEMENT
Environmental education opportunities exist for the citizens within the watershed through
various avenues.
Ecology Field Days
Warren SWCD is committed to their annual environmental field days in which they educate
school age children on the benefits of conservation, agricultural BMPs and rural/urban BMPs.
Annual Agricultural Outreach Event
A joint effort with the Natural Resources Conservation Service (NRCS), Farm Service Agency
and the Warren SWCD is involved in organizing this annual dinner for the agricultural
community. Each represented agency promotes the programs and services that they offer as well
as update the audience on the status of current projects.
Warren County Government Day
Sponsored by Warren County, each department has the opportunity to participate by including a
booth in the event. At this time the Warren SWCD educates citizens about their services as well
as rural/urban conservation practices.
Cost Share Tour
Warren SWCD sponsors this event to educate the local and state leaders and officials on the
agricultural initiatives that are occurring within Warren County.
Warren County High School Agriculture Tours
This unique opportunity allows the Warren SWCD staff to be included in the Agriculture
Science curriculum. Staff provides education information in a classroom setting to the students
then takes them on field tours to see conservation at work. The information that is covered in the
lesson includes conservation, stream bank protection, erosion control and buffers.
Annual Contests
Each year the Warren SWCD promotes Poster contests for grades 3-6; Essay contests and Public
Speaking Contests for grades 7-8. Each year the NC Association of Soil and Water Conservation
Districts establishes a current environmental issue as the topic.
NC Envirothon
The Warren County SWCD promotes high school teams of 5 students to participate in the NC
Envirothon. This program tests the knowledge and skills of the team on the following subjects:
Forestry, Aquatics, Soils, Current Environmental Issues, and Wildlife. The SWCD staff assists
Smith Creek Watershed Restoration Plan (May 2008) 7
the students throughout the school year in educating and training their teams on these topics.
This hands-on approach to learning is a great opportunity for all students and staff.
Education meetings that have taken place for the Smith Creek project include:
• Warren SWCD spoke about the Smith Creek Watershed project to 185 people attending
the annual USDA Outreach meeting (October 26, 2006)
• Warren SWCD gave a slide presentation to approximately 125 local high school students
in the FFA/agricultural class covering BMPs that were going to be installed in the Smith
Creek Watershed (November 1, 2006)
• Warren SWCD conducted a BMP Field Tour with approximately 50 local high school
FFA/agricultural students that showcased multiple farm sites exclusively in the Smith
Creek Watershed (November 14, 2006)
MEASURES OF SUCCESS
Implementation of BMPs that will achieve the greatest decrease in sedimentation within Smith
Creek will be the primary factor during prioritization of cost share applications. Applications
will be solicited with a specific deadline established. A site visit will be conducted for all
applicants to evaluate the erosion problems and suggest solutions to correct the issue. Such
practices that may be suggested as corrective measures include but are not limited to grassed
waterways, field borders, livestock exclusion from the creek by fencing, and heavy use
protection areas. This project will also focus on promoting agronomic farm management
techniques that will also decrease the sediment load into the water body. These practices include
sod-based rotation and long term no till. Information will be collected at each site such as slope,
crop rotation, farm management practices, drainage area and size of gullies, if applicable, in
order to calculate the potential soil loss before and after BMP installation. The Revised
Universal Soil Loss Evaluation calculations will be utilized in this process. Each applicant will
then be ranked based upon the reduction of soil loss and distance from stream, at minimum.
As work is accomplished through this initiative, a direct result may be removal of Smith Creek
from the NC 303(d) list. The water quality monitoring data will give specific results as to the
effectiveness of BMP implementation. A comparative analysis of the field assessments with the
water quality improvements would be an asset to future projects.
WATERSHED CHARACTERISTICS
Watershed Description
The Smith Creek Watershed is 34,500 acres and is located almost entirely within Warren
County. This watershed is part of the larger Roanoke River Basin system, which ultimately
flows into the Albemarle Sound.
Smith Creek Watershed Restoration Plan (May 2008) 8
The Smith Creek Watershed contains seven major tributaries as well as Smith Creek (see Figure
2). The major tributaries are: Ellington Branch, Newman’s Creek, Cabin Branch, Terrapin
Creek, Malone’s Creek, Blue Mud Creek and Reedy Branch.
Figure 2: Map of Smith Creek Watershed and Major Tributaries.
According to the U.S. Census Bureau, Warren County had a median household income of
$27,812 in 2004, compared to a statewide median household income of $40,863 and a national
median household income of $44,334. Therefore, funding such as this Section 319 grant allows
for farmers in Warren County to implement best management practices that they and the local
Soil and Water Conservation District would not otherwise have the means to install.
The population of Warren County increased by almost 16% from 1990 to 2000, going from
17,265 to 19,972. The population is expected to increase to 22,237 by 2010 and 24,183 by 2020.
The township of Smith Creek has not experienced a significant change in population from 1970
to 2000, going from 2,020 to 2,198, with increases to 2,330 in 1980 and 2,266 in 1990.
However, the township of Smith Creek did have 297 new dwelling units in 1990 compared to
1970.

Soils
The soils of the Smith Creek Watershed located in Warren
County N.C. are contained entirely within the Piedmont
geographic section of the state. Three main geologies make up
the watershed: granite, granite-gneiss and fluvial sediments
(flood plain material). One percent or less of the watershed
contains soils derived from coastal plain remnants, or
"capping". The upland soils are derived from the acid
crystalline granite based rocks.
For a more detailed look at the soils contained within the
Smith Creek Watershed, please refer to the available Warren
County Soils Maps and the Warren County Soils Legend
(Figure 3). At present, there is an ongoing Progressive Soil
Survey underway in Warren County. As of this report, about
98 percent of the Smith Creek Watershed has complete soils
mapping available.
Note that these are the major soil units found in Smith Creek Watershed. They are by no means
the only soils found in Smith Creek. Also be aware that none of the areas depicted on the
General Soils Map are purely the soil unit depicted. The depiction merely means that these areas
are predominated by that particular soils unit.
Cecil and Pacolet - Characterized as very deep, well drained soils with red colored, clayey
subsoil. These soils are considered suitable for most uses and practices common to the area.
Vance - These are very deep, well-drained soils with yellowish colored clayey subsoil. Generally
suitable for agriculture, but may have limitations where permeability of water is concerned.
These soils are not generally recommended for residential development.
Appling and Wedowee - Basically the "yellow" counterpart to Cecil and Pacolet soils. Appling
and Wedowee may even have a slight advantage over their red counterpart (especially for
agriculture) due to a generally thicker surface horizon. These soils are also considered suitable
for most uses and practices common to the area.
Helena - Characterized as very deep, moderately well drained soils with clayey, yellow subsoil.
Usually suitable for agriculture except during extremely wet periods, this soil is generally not
recommended for building site development or any practice with might be adversely affected by
wetness or slow permeability.
Chewacla and Wehadkee - These are very deep somewhat poorly and poorly drained soils with
loamy subsoils. Commonly known as flood plains, these soils exhibit a high water table. Unless
Figure 3: General Soils Map of the Smith
Creek Watershed
Smith Creek Watershed Restoration Plan (May 2008) 10
drained and protected from frequent flooding, these soils make for a poor choice in any usage
except woodland or the occasional pasture or hayland. Few acres of these soils are used in
agriculture.
Wake-Louisburg-Saw - These soils have characteristics that range from very shallow to bedrock
to deep and droughty. Not considered a desirable soil for agriculture or development, but a
sizable amount is used in the former. Most of its agricultural acreage is used as pasture because
of bedrock at the surface that would impede conventional agricultural equipment.
Mattiponi - These soils are moderately to well drained, clayey soils derived from coastal plain
"capping". They are found on the highest elevations in the county and contain many "inclusions"
of the above-mentioned upland soils. Mostly suitable for agriculture and other uses, this soil is
limited in acreage and should be considered a minor component in the Smith Creek Watershed.
According to the Warren County-2022 Comprehensive Development Plan (Land Use Plan), soils
with characteristics best suited for agriculture, contain significant environmental features, or
have significant wetland classifications, need to be protected. Caution should be exercised when
developing around all surface water locations and groundwater recharge/discharge points.
Careful development of these areas needs to be enforced to manage stormwater runoff and
sedimentation of water resources, wetlands, and floodplains. Land surrounding these surface
water sources can act as a buffer to minimize negative impacts on water quality, provide tree
cover, and add to open space conservation for the County.
Land Use
The land use in the Smith Creek Watershed is approximately 55% wooded land, 43%
open/undeveloped land and 2% urban/residential.
Land use changes in the past 5-10 years within the watershed include agricultural operations that
have changed farming practices from conventional planting methods to soil saving, high residue
management conservation tilled methods. Along with the reduction of row crops such as
tobacco to planting permanent cover such as fescue and/or trees. Also, some farmland has been
retired and homes built.
While Warren County is classified as rural, with a predominantly agricultural economy, there is a
growing commercial and industrial component, specifically near the US-158 and I-85 corridor
(Warren County-2022 Comprehensive Development Plan, 2002).
Water Quality
A map showing existing Best Management Practices is provided (Figure 4) and a corresponding
table describing the type of BMP at each locations can be found in Appendix A.
Smith Creek Watershed Restoration Plan (May 2008) 11
Appendix B contains photos and descriptions for sites that are in need of agricultural BMPs.
Table 4 in the Implementation Program section of this plan summarizes the BMP needs compiled
in Appendix B.
As development occurs, the impact on water resources becomes greater, increased housing and
industry reduces available land cover, affects water quality and agriculture (Warren County-2022
Comprehensive Development Plan, 2002). This same development will affect aquatic habitats
by changing vegetative cover, increasing stream temperature, and reducing the food supply for
aquatic life.
Nonpoint source pollution can include uncontrolled agricultural practices, distribution of
pesticides and fertilizers, sediment runoff from construction sites, or runoff from an overflowing
wastewater station or septic drain field (Warren County-2022 Comprehensive Development
Plan, 2002).
The Warren County-2022 Comprehensive Development Plan states, “although agricultural
practices are the most prevalent cause for impaired water quality and watersheds, Warren County
Figure 4: Locations of Existing BMPs in the Smith Creek Watershed.
Smith Creek Watershed Restoration Plan (May 2008) 12
has done well (in comparison to other areas in NC) in proper agricultural practices to maintain
water quality and protect its watersheds. In addition, farmers have been using BMPs (Best
Management Practices) to reduce nitrogen and phosphorus being discharged into surface waters
around their land.”
Identification of Causes and Sources of Pollution that Need to Be Controlled
The Roanoke River Basin is included in the NC Division of Water Quality Basinwide planning
program. This program identifies impaired waters and their potential sources for impairment.
Recommended actions are also included in the completed Basinwide Plan in hopes to restore
these waters to full use support ratings. The Smith Creek watershed has been listed as an
impaired stream on the NC 303(d) Impaired Waters for many years. The assessment in 1998
stated that the biological integrity of this watershed was impaired. The Division of Water Quality
based these determinations on benthic macroinvertebrate studies. In 2002 Smith Creek continued
to be included on the 303(d) list with the addition of declining dissolved oxygen levels. The 2004
and 2006 303(d) lists also include Smith Creek as being biologically impaired, as well as
impaired due to low dissolved oxygen. Erosion and sedimentation from agriculture are identified
as being the potential source for the impairment.
The NC Division of Water Quality Basinwide Assessment Reports stated that the lowest levels
of dissolved oxygen concentrations within the entire Roanoke River Basin were from Smith
Creek, near Paschal. This data was collected from an ambient monitoring station at the lower
end of the creek in 1999. In addition approximately 25% of all samples taken at this site were
less than the water quality standard of 5.0 mg/l. Stagnant conditions, caused by beaver dams, are
suggested to be another contributor to the low dissolved oxygen levels and biological
impairment.
The 2004 Stressor Survey supported the fact there are several pasture-based beef cattle
operations where the animals have direct access to streams. Smith Creek Watershed is also the
home of confined animal operations including: 2 dairies, 2 swine operations, and 3 poultry
operations. Currently there are no NPDES permitted discharges within the watershed. Norlina is
the only incorporated town within the watershed with a population of approximately 1,000
residents.
The Division of Soil and Water Conservation (DSWC) and Warren Soil and Water Conservation
District (SWCD) will assess the local sources of sedimentation in the watershed beginning with
those identified in the 2004 Stressor Survey. Development and implementation of a watershed
restoration plan to address high-priority sources will be coordinated with the Division of Water
Quality – Environmental Sciences Branch, the Division of Water Quality Basinwide Planning
staff as well as the Ecosystem Enhancement Program staff.
In June 2004 further assessment of the watershed took place in which a more in depth analysis
was made. Similar conclusions were made regarding habitat degradation and biological
impairment. This Stressor Survey also generated an explanation for the very high iron
concentrations. Previously, the reports stated that 86% of the 50 samples taken between 1994 and
Smith Creek Watershed Restoration Plan (May 2008) 13
1999 exceeded the water quality standard for iron. The Basinwide Assessments show that over
the past fifteen years this conductivity trend has been increasing. Such high levels of iron are not
unusual because of their presence in the local soils, however the increase of these soils entering
into the surface water from sedimentation could be the source.
Erosion and sedimentation from agriculture was identified as being the potential source for the
impairment. Approximately 55% of the land use in the watershed is wooded, 43%
open/undeveloped and 2% urban/residential. The Smith Creek Watershed has slopes from 2% to
greater than 15% in areas. This variability in landscape results in the area being highly
susceptible to erosion, primarily from agriculture. Most of the cropland is conventionally tilled
which contributes a great amount of sedimentation into the Smith Creek.
Smith Creek Watershed Restoration Plan (May 2008) 14
PROJECT GOALS
Estimate of the Load Reductions
An estimated 6,000-ton reduction of sediment is expected from the implementation of Best
Management Practices (BMPs) within the Smith Creek Watershed. The majority of this
reduction will be from implementing sediment reducing agronomic farming practices such as
long-term no-till and sod based rotation. Vegetative and structural BMPs, such as field borders,
grassed waterways, and heavy use protection areas will also play a vital role in reducing the
amount of sedimentation entering into the creek and its tributaries. Such sediment controls can
repair gulley erosion that may be occurring at the edge of the agricultural field.
Implementation of livestock exclusion practices will also be a vital component of the success of
this project. BMPs installed on sites where cattle have been allowed access to the streams may
show the most benefits to water quality in the shortest timeframe. Excluding animals from the
creek and repairing the streambanks with native vegetation and additional engineering work, as
necessary, should decrease the levels of turbidity at the previous sample sites.
While the practices applied are primarily aimed at reducing sediment losses, phosphorus and
nitrogen losses reductions are anticipated as well (estimated to be 15,000 lbs and 25,000 lbs
respectively according to PLAT/NLEW methods).
Pasture Based BMP System
A typical beef operation pasture based system in the Smith Creek Watershed consists of free-
range animals that have open access to various watercourses through the watershed.
The Warren SWCD will promote the use of pasture related BMPs to offset this water
quality/sedimentation problem. In most cases BMPs such as livestock exclusion, heavy use
protection areas and alternative watering systems along with rotational grazing will be
implemented. It is estimated that the installation of livestock exclusion (fencing) alone will save
a minimum of 12 to 23 tons per acre of soil from future degradation of the streambanks.
Cropland BMPs
Warren County producers in the Smith Creek Watershed are producing tobacco, cotton,
soybeans, corn, small grain and hay crops. Warren SWCD has implemented an aggressive
erosion control program on this watershed. Some of the BMPs installed on cropland and the
estimated soil loss reduction are listed below.
Table 1 contains estimates of tons of soil saved per acre when particular BMPs are implemented,
on soils that are commonly found throughout the Smith Creek Watershed.

IIe – Soils that have moderate limitations that reduce and restrict their use
IIIe – Soils that have severe limitations and require strategic planning
IVe – Soils that have very severe limitations and require a higher degree of planning
Description of NPS Management Measures to Achieve Goals
The goal of the watershed implementation plan is to reduce the amount of sedimentation that
occurs in the Smith Creek watershed from agricultural operations. The overall purpose of this
initiative is to reestablish the biological integrity of the waters so that they can become fully
supporting for aquatic life and secondary recreation within the next five years. Management
measures will rely heavily on installing sediment control practices approved by the NC Soil and
Water Conservation Commission. A full description of the agricultural and stormwater BMPs
that are recommended to reduce sedimentation in the Smith Creek Watershed can be found in
Appendix C. The following management actions will need to be taken to successfully meet this
goal:
Control Sediment and Nutrients from Pasture Operations
The objective of this action is to prevent future sedimentation and nutrient loading due to cattle
access to surface waters. Those operations that allow cattle to use the stream as a water source
and crossing will be the priority for technical assistance and financial assistance. Heavily
overgrazed pastures adjacent to the creek and its tributaries will also be a parameter in the
prioritization process. These areas will be corrected by installing BMPs that include but are not
limited to the following:
Smith Creek Watershed Restoration Plan (May 2008) 16
• Heavy use protection areas
• Livestock exclusion system
• Alternative water sources
• Streambank stabilization
• Stream crossings
The Warren SWCD, Natural Resource Conservation Service (NRCS) and the Division will
provide technical assistance related to these practices.
Financial support will be provided for the installation and 10-year maintenance of these
practices, as funds are available. These funds are awarded based upon established water quality
criteria such as proximity to the stream and total reduction of the sediment and nutrient
contribution. Warren SWCD will be responsible for routine inspections of installed practices.
Control Sediment and Nutrients from Row Crop Operations
The objective of this action is to prevent future sedimentation and nutrient loading from row crop
agricultural fields. Farms that are currently not practicing crop residue management and
conservation tillage, as well as those sites that have severe gully erosion occurring on their fields
will be placed as priority sites. These areas will be improved by installing BMPs that include but
are not limited to the following:
• Sod based rotation
• Long-term no till
• Field borders
• Streambank stabilization
• Filter strips
• Grassed waterways
The Warren SWCD, NRCS and the Division will provide technical assistance related to these
practices.
Financial support will be provided for the installation and maintenance of these practices, as
funds are available. These funds are awarded based upon established water quality criteria such
as proximity to the stream, total reduction of the sediment and nutrient contribution and wildlife
benefits. Warren SWCD will be responsible for routine spot checks of installed practices.
Identify Water Flow Management Strategies
Smith Creek watershed is a rural community that is composed of primarily agriculture and forest
land. In such an environment it is not uncommon for storm debris to block the natural drainage
ways causing water flow to decline or stop all together. An excessive beaver population can
also contribute to conditions that cause water stagnation. Warren County is a participating
member of the Beaver Management Assistance Program (B-MAP). This program is not intended
to eradicate the entire beaver population, however the program will reduce the population at a
particular site to prevent adverse environmental and negative economic problems. The Warren
Smith Creek Watershed Restoration Plan (May 2008) 17
SWCD will coordinate efforts to address such sites so that it would decrease flooding hazards as
well as increase the flow of Smith Creek.
Coordinate Streambank Stabilization Projects
Although it has been suggested that the primary source of the sedimentation in the watershed is
agricultural operations, the Division and the Warren SWCD are committed to identifying sites
along Smith Creek and its tributaries in which streambank stabilization is required. In many
cases, the natural stream channel may be deteriorating because of the scouring affect of unusual
storm events. On sites where cattle may have been allowed access to the creek, streambank
reconstruction and stabilization may be required.
When such instances occur, the Warren SWCD will work diligently to initiate and oversee the
repairs of the creek. Partnering agencies such as the NRCS, the Division of Soil and Water
Conservation and the Ecosystem Enhancement Program may be contacted to provide required
engineering assistance to properly stabilize the area.
Smith Creek Watershed Restoration Plan (May 2008) 18
IMPLEMENTATION PROGRAM
Schedule for Implementing the NPS Management Measures
Landowner applications for financial assistance will be accepted until September, on an annual
basis. The next stage will be to prioritize each application based upon water quality benefits
expected from the desired BMPs. Installation of BMPs will continue throughout the year
pending weather conditions.
Table 2 contains the schedule for implementing BMPs in the Smith Creek Watershed. Table 3

Measurable Milestones
Annual progress reports will be utilized to determine whether objectives are being met. This
information will include BMPs installed during the current cycle as well as to date. Projects that
have been planned but not yet implemented will be reported to demonstrate future water quality
benefits. Data will be included regarding the amount of sediment that has been reduced due to
the implementation of this project. Nitrogen and Phosphorus reductions will also be included.
Monetary comparisons between amounts that were used from cost share funding verses actual
installation costs will be a component of our accountability. The change in water quality
improvements will be documented throughout the project with the assistance of DWQ-
Environmental Sciences Section (ESS) and their monitoring services.
Criteria for Determining Loading Reductions
The Revised Universal Soil Loss Equation formula (RUSLE) will be used to determine the tons
of soil lost prior to BMP installation as well as after. RUSLE takes into consideration the soil
type of the site, slope, cropping sequence and residue management practices. The North Carolina
Agricultural Nutrient Assessment Tool (NCANAT) will be utilized to determine the amount of
Nitrogen and Phosphorus reduction that will be achieved. This accountability tool utilizes the
inputs for RUSLE as well as the following data to calculate the estimated reductions:
• Nitrogen uptake efficiencies for major crops in NC
• Nutrient reduction credits for installed BMPs

Appendix D contains documentation for Gully Erosion Computation and the Revised Universal
Soil Loss Equation Worksheet.
Water Quality Monitoring
An agricultural sediment baseline was determined for each site. This data enabled a baseline to
be established and will allow for a reduction to be calculated. Each contract will be required to
maintain the BMPs per the Soil and Water Commission Standards/NRCS Standards. These sites
will also be included in annual spot checks to assure compliance. Each site will be mapped to
demonstrate the location and proximity to Smith Creek and its tributaries. This information will
be provided to the Division of Water Quality to contribute to their Roanoke Basinwide Planning
Program. The Environmental Science Branch will also be able to utilize this information to
provide an explanation of future water quality monitoring data.
Education and Outreach
The overall goal of the community education program in the Smith Creek watershed is to
develop an atmosphere that encourages long-term protection and improvement of water
resources in the watershed (see Appendix E for a copy of the educational brochures).
Various educational opportunities will be included within the implementation phase of the
project that will include the following objectives:
• Increase public awareness of the value of clean water
• Increase public awareness of how common activities contribute to nonpoint source
pollution and poor water quality
• Increase public awareness of how conservation practices can reduce negative impacts on
water quality and habitat degradation
• Increase public awareness of how the protection of water quality can contribute to the
environmental and economic benefits of the watershed.
Education Activities
• Ecology Field Days: Warren SWCD is committed to their annual environmental field
days in which they educate school age children on the benefits of conservation,
agricultural BMPs and rural/urban BMPs.
• Annual Agricultural Outreach Event: A joint effort with NRCS, Farm Service Agency
and the Warren SWCD and involves organizing an annual dinner for the agricultural
community. Each represented agency promotes the programs and services that they offer
as well as update the audience on the status of current projects.
Smith Creek Watershed Restoration Plan (May 2008) 21
• Warren County Government Day: Sponsored by Warren County, each department has the
opportunity to participate by including a booth in the event. The Warren SWCD educates
citizens about their services as well as rural/urban conservation practices.
• Cost Share Tour: Warren SWCD sponsors this event to educate the local and state
leaders and officials on the agricultural initiatives that are occurring within Warren
County.
• Warren County High School Agriculture Tours: This unique opportunity allows the
Warren SWCD staff to be included in the Agriculture Science curriculum. Staff provides
education information in a classroom setting to the students and then takes them on field
tours to see conservation at work. The information that is covered in the lesson includes
conservation, stream bank protection, erosion control and buffers.
• Annual Contests: Each year the Warren SWCD promotes Poster contests for grades 3-6;
Essay contests and Public Speaking Contests for grades 7-8. Each year the NC
Association of Soil and Water Conservation Districts establishes a current environmental
issue as the topic.
• NC Envirothon: The Warren SWCD promotes high school teams of 5 students to
participate in the NC Envirothon. This program tests the knowledge and skills of the team
on the following subjects: Forestry, Aquatics, Soils, Current Environmental Issues, and
Wildlife. The SWCD staff assists the students throughout the school year in educating
and training their teams on these topics. This hands-on approach to learning has proven
to be a great opportunity for all students and staff.
Educational activities completed to date as part of this project include:
• October 26, 2006: During the annual USDA Outreach meeting, Larry West spoke briefly
about the Smith Creek Watershed Project to the crowd of 185 people who were in
attendance.
• November 1, 2006: Larry West conducted a slide presentation to the local High School
FFA/agricultural class illustrating BMPs that were going to be installed in the Smith
Creek Watershed.
• November 14, 2006: Larry West conducted a BMP field tour with the local High School
FFA/agricultural class students that showcased multiple farm sites exclusively in the
Smith Creek Watershed. Approximately 50 students participated in the Smith Creek
Watershed BMP tour.

Estimate of the Technical and Financial Assistance Needed
Section 319 Agricultural Sediment Initiative
Estimated technical assistance that will be needed to effectively implement this project is
$32,625. However the Warren SWCD is providing their services without reimbursement to
implement this project. An additional $108,000 will be needed to assist landowners in installing
BMPs on priority sites. The Warren SWCD has placed this watershed as a priority on their NC
Agriculture Cost Share Strategy Plan. A total of $130,000 was requested to adequately fund the
Smith Creek Agricultural Sediment Initiative and was awarded via the Section 319 Program
beginning FY06 (July 15, 2005).
The programs to implement the grant will be promoted by conducting BMP field tours,
developing media articles, conducting workshops at local high school agricultural class,
conducting presentations to local cattleman's association, civic groups, local business meetings
and other commodities groups as deemed necessary. It is estimated that 950 hours will be
dedicated to this task.
The Warren SWCD anticipates that assistance in the planning, designing, installation and
certification process will consist of a combined 1,920 hours from the Warren SWCD, NRCS Soil
Survey office, Warrenton NRCS and NRCS Area II Staff.
Smith Creek Watershed Restoration Plan (May 2008) 23
It is estimated that a total of 2,870 hours with a cost of $65,000 will be required to meet the
objectives described above.
Additional Conservation Measures and Funding Needed in the Smith Creek Watershed

11 Heavy use protection area $6,000
Total $130,076
The estimated cost is representative of the 75% cost share rate. These sites need to be addressed
in Smith Creek. However, the problem in this watershed (and most other ones) is that most
Smith Creek Watershed Restoration Plan (May 2008) 24
landowners do not have the initial money to pay for completed conservation practices and wait
for the reimbursement from conservation agencies.
Sites 1 through 11 just represent a snapshot of the Smith Creek watershed. It is not realistic to
think that all conservation issues will be resolved in any impaired watershed. Lack of money is
the driving factor, but sometimes the landowner just is not interested in doing what is
environmentally sound. But, the Smith Creek project (Phases I and II) will make a positive
impact on the water quality in this watershed.

BUDGET SUMMARY
This project was funded under the United States Environmental Protection Agency Section 319
Grant Program, administered by North Carolina Division of Water Quality.
Table 5 contains the budget summary for the Smith Creek Watershed Project. While the project
was underway, the Warren Soil and Water Conservation District decided to do the majority of
the work for the Watershed Restoration Plan instead of subcontracting the work out to a
consultant. This resulted in the WRP being done at a cost less than originally anticipated and
therefore the remaining money was moved to the Construction (BMPs) line item. This line item
change allowed more Best Management Practices to be implemented, therefore increasing the
water quality benefits in the Smith Creek Watershed.
