Deep Creek Watershed Structure 5D Mitigation Project Year I of 5 Monitoring Report
Dinkins Bottom Wetland Mitigation Site November 2010

1.0 Project Overview
The Deep Creek Mitigation Project (Site) is located in Yadkin County, North Carolina within the
Northern Inner Piedmont Eco- Region of the Yadkin River Basin (USGS HUC 03040105). The
Site consists of three separate mitigation projects (Dinkins Bottom Wetland Restoration, Carl
Shore Stream Restoraiton and Effie G. West Stream Enhancement Sites) that were a component
of the mitigation plan to address wetland and stream impacts resulting from the construction
ofthe multiple - purpose Structure 5D.. The Structure 5D is part of The Deep Creek Watershed
Work Plan that was approved for operations on January 31, 1958. The project was authorized
through the Watershed Protection and Flood Prevention Act — Public Law 83 -566, as amended
(US U.S.C. 1001 - 1008). The project sponsors were the Yadkin Soil and Water Conservation
District andYadkin County Board of Commissioners.
Structure 5D is a multiple - purpose structure that was designed for flood prevention and
municipal /industrial water supply in the Deep Creek Watershed. The Structure 5D is located on
South Deep Creek immediately upstream from old US 421 and has a, drainage area of 25.01
square miles (sq.mi.). The surrounding land use consists of forestland, cropland, grassland, and
miscellaneous or built -up land. Approximately 12.7 acres (ac) of seasonally saturated bottomland
hardwood habitat were inundated due to the permanent pool of Structure 5D. Both stream and
wetland mitigation issues were addressed within this project.
1.1 Project Goals and Objectives
The following mitigation goals were established within the Deep Creek Watershed to
compensate for the unavoidable loss of seasonally saturated hardwood habitat areas.
1. Restore approximately 16.8 ac of wetland,
2. Improve water quality by increasing nutrient removal and transformation as well as
removing sediment and possible toxic materials,
3. Enhance wildlife habitat through the increased storage of surface and subsurface storage,
and
4. Provide an outdoor education classroom for Yadkin County by developing of trails and a
boardwalk through the restored wetland.
This report serves as the Year aHe (2010) annual monitoring report of the five year monitoring
plan for the Dinkins Bottom Wetland Restoration Site of the Deep Creek Mitigation Project.
1.2 Project Location
The Dinkins Bottom Wetland Restoration Site is located southeast of the Town of Yadkinville,
approximately 14 miles downstream of Structure 5D. The project is located in the Yadkin -Pee
Dee River Basin, Catalog Unit 03040105 with a watershed land use dominated by rural pasture
land and forest. The area selected for restoration is a 26 ac tract, which included 16.8 ac suitable
for wetland restoration and 9.2 ac for upland hardwood habitat, education trails/boardwalk, and
gravel access roads and parking lots.

Hydric soil boundaries within the project area were determined in the field by Bill Woody,
NRCS Soil Scientist, Salisbury, NC. The dominate soil mapping units perthe Yadkin County
Soil Surveywithin thel6.8 acreproject area are Augusta silt loam, Chewacala silt loam, and
Wehadkee silt loam. The remaining 9.2 acres consist of State fine sandy loam and Wickham fine
sandy loam, 7 to 12% slope, eroded.
To access the site from Charlotte, North Carolina, take Interstate 77 North for approximately 62
miles to exit 73A (US -421 South). Follow US -421 South to exit 249, Baltimore /Dinkins Bottom
Road and turn right at the end of the exit ramp onto Dinkins Bottom Road. Take Dinkins
Bottom Road approximately 1 mile and turn left onto Farmington Road. Please refer to Figure 1
for a location map of the project site.
2.0 Monitoring Success Requirements
Annual monitoring will consist of collecting hydrologic and vegetative data to assess the project
success based on the restoration goals and objectives. The site will be monitored for five years
(beginning in 2A� with an annual monitoring report submitted to the corps within 30 days of
the monitoring activities.
2.1 Wetland Hydrology
Wetland hydrology attainment will be monitored in accordance to the United States Army Corps
of Engineers (USACE) (2003) standards as stated in the mitigation plan (2005). The target
wetland hydrological success criterion is saturation or inundation for at least 5 percent of the
growing season in the lower landscape (floodplain) positions. To achieve the above hydrologic
success criterion, groundwater levels must be within 12- inches of the ground surface for 10
consecutive days, which is 5 percent of the April 11 to October 30 growing season.
2.2 Wetland Vegetation
Planted vegetation will be monitored for five years following a stem count protocol, which
consists of counting woody stems within the established vegetation plots. To achieve vegetative
success criteria the average number of planted stems per acre must exceed or meet 320
stems /acre after the third year of monitoring, 288 stems /acre after four years, and 260 stems /acre
after the fifth year of project monitoring.
2.3 Reference Photograph Points
Permanent photographic reference points established along the wetland will be used to support
the qualitative visual assessments for the annual monitoring and subjectively evaluate success of
vegetation and hydrology.
2.4 Maintenance and Contingency Plans
Potential problem areas, such as unsuccessful vegetation establishment or hydrology attainment
will be evaluated during the annual monitoring. If, during the annual review of the wetland area,
a failure is noted, the areas will be evaluated and discussed with appropriate personnel to

determine if remedial maintenance measures are required to resolve the problem. If remediation
of an area is required, a proposal will be submitted for the needed work.
3.0 Year 1 Monitoring Results
Results from the 2010 wetland monitoring effort indicate that the Dinkins
mitigation goals in all proposed areas.
3.1 Hydrology Assessment
Seven groundwater monitoring gauges are located on site. The me
measured bi- weekly from January to October in order to capture hydrologic data during the
growing season. Automated gauges have been installed and are programmed to download water
levels daily. These gauges will be used to report hydrology success criteria for all upcoming
monitoring years.
Groundwater monitoring results from the 2010 monitoring year indicate that four of the seven
groundwater gauges (1, 2, 3, and 7) achieved the wetland success criteria of saturation for 10
consecutive days (5 %) during the growing season. Gauges 5 and 6 did not meet the wetland
success criteria. However, topographic constraints may be contributing to the lack of wetland
hydrologic success at these gauges. Groundwater gauge 4 was noted as unknown due to the lack
of data available. This gauge most likely will meet success criteria once daily monitoring is
recorded in the subsequent monitoring years. Please refer to Appendix 2 for wetland monitoring
data and a summary table of the wetland criteria attainment.
3.2 Vegetative Assessment
The 2010 vegetation monitoring results indicated that the Site is meeting vegetative success
criteria. The average site density is approximately 936 planted stems per acre, which exceeds the
year one goal of 320 planted stems per acre. There is an average of 50 live planted stems per
plot. A review of the natural recruits monitored indicates an increase in the average site density
of approximately 1,672 stems per acre. There is an average of 109 recruitment stems per plot.
Please refer to Appendix 2 for more detailed information on the 2010 vegetation data.
In summary, the Dinkins Bottom site has met the wetland and vegetation mitigation goals for
monitoring year 1. The background information provided in this report is referenced from the
mitigation plan. Please refer to Appendix 2 for more detailed data tables and plots for
monitoring year one and Appendix 3 for representative photographs.
