The Site consists'of three separate mitigation projects (Dinkins. Bottom Wetland Restoration, Carl ° Shore Stream Restoration 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 of the a rultiple- purpose Structure 5D. `The Structure 5D is part of the Deep Creek Watershed Work Plan that was approved for operations on January 31,J958. 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' and Yakin County Board of Commissioners. Structure 5D is a multiple- purpose structure that was designedf for flood prevention and . municipal/industrial water supply in the-Deep Creek Watershed. The Structure 5D is located on South V ep 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 efor 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 removin sediment and possible toxic materials, 3. Enhance wildlife habitat through °the increased storage of surface and subsurface storage This report serves as, the Year four (2012) annual monitoring -report °of the five year monitoring plan for, the Dinkins Bottom Wetland Restoration site of -the Deep Creek Mitigation Project. i 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 suitable for wetland restoration and 9.2 ac for upland hardwood habitat, education trails/boardwalk, and °gravel access roads and parking lots. Page 3 of 6 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 per the Yadkin County Soil Survey within the 16.8 acre project area are Augusta silt loam, Chewacala silt loam, and Wehadkee silt- loam. The remaining 9.2 acres consist of State fine sandy loam and Wichham 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 °bnto.Dinkins Bottom Road. Take. Dinkins e, r Bottom :Road approximately 1 mile, site on right. 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 2009) with anaannual 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 wedand (" 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 March 45- 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, Page 4 of.6 a failure is noted, the areas will be evaluated and discussed with appropriate personnel to e, determineif remedial maintenance measures are required to resolve the problem., If remediation Of aK area is required, a- proposal will be submitted for the needed work. 3.0 Year 4 Monitoring Results Results from the 2012 wetland monitoring.effort indicate that the Dinkins Bottom Site is meeting mitigation goals in all proposed areas. 3.1 Hydrology Assessment 'Eight groundwater monitoring gauges are located on site. We installed the #8 well in February of 2012: 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 2012 monitoring year indicate that six of the eight groundwater gauges (1,2;3,4, 7 & 8) achieved the wetland success criteria of saturation for 10 a :'consecutive days (5 9/6), during the growing season. Gauge 6 did not meet the wetland success criteria. °However, topographic constraints may be contributing to the lack of wetland hydrologic success at these,gauges. ° Please refer to Appendix 2 for wetland monitoring data and a summary table of the wetland criteria attainment. ( 3.2 Vegetative Assessment ° ,a e The 2012 vegetation monitoring results indicated that. the *Site is meeting vegetative success criteria. The average site density is approximately 840 planted stems per acre, which exceeds the year four goal of 288 planted stems per acre. There is an average of 42 live planted stems per plot. There b was, a concern of too many Sweet Gum in plots 8 and 9 so we performed a hack & squirt method in the fall of 2011 & 2012, in order to thin some of these unwanted° species. The results should show up in the 2013 Stem Count. Please refer to appendix 2 for more detailed information on the 2012 vegetation data. In summary, the Dinkins Bottom site has met the wetland and vegetation mitigation goals for monitoring year 4. The background information provided in this report is referenced form the mitigation plan. Please refer to Appendix 2 for more detailed data tables and plots for monitoring year four and Appendix 3 for representative photographs. 8 Deep Creek Watershed Structure 5D Mitigation Project Dinkins Bottom Wetland mitigation Site .-Page 5 of 6 Year 4 of 5 Monitoring Report November 2012 APPENDIX I -FIGURES Figure L.
