Tree species in immediate surrounding area are species that typically prefer drier conditions. Jean said not to waste money on trying to save these wells. • Tree thinning will be good for the site. Jean said not to cut all unwanted species and to be careful not to cut good species that have come in on their own. • Restoration area, in total, is lacking around 2 acres. Jean said that is would probably be best just to buy the remaining acres from EPA. Effie West • This site has relatively good quality just based on the mayflies, stoneflies, caddisflies, and crayfish found. • Some of the live stakes are not doing so well. Jean said to watch out for damage from deer. • Overall quality of site will increase with more shade. Carl Shore • Stream quality not as good as Effie West because of runoff from agriculture upstream. Increasing shade will help with turbidity and creating a better habitat for sensitive benthic invertebrates. • Live Stakes are doing much better at this site, may need to spray for Privet soon. • Beaver damage needs to be a little more controlled 1.0 Project Overview The Deep Creek Mitigation Project (Site) is located in Yadkin County, North Carolina within die 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 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 die multiple- purpose Structure 5D. The Structure 5D is part of die 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 die Yadkin Soil and Water Conservation District and Yakin 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 foresdand, 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 wedand 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 die unavoidable loss of seasonally saturated hardwood habitat areas. 1. Restore approximately 16.8 ac of wedand. 2. Improve water quality by increasing nutrient removal and transformation as well as removing sedihnent and possible toxic materials, 3. Enhance wildlife habitat through die increased storage of surface and subsurface storage This report serves as the Year three (2011) annual monitoring report of the five year monitoring plan for die Dinkins Bottom Wedand Restoration site of die Deep Creek Mitigation Project. 1.2 Project Location The Dinkins Bottom Wedand Restoration Site is located southeast of die town of Yadkinville, approximately 14 miles downstream of Structure 5D. The project is located in the Yadkin -iPee 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 wedand 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 die 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 Wicliliam fine sandy loam, 7 to 129,/o 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 die end of die exit ramp onto Dinkins Bottom Road. Take Dinkins 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 an annual monitoring report submitted to the corps within 30 days of die 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 die growing season in die 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- 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 die established vegetation plots. To achieve vegetative success criteria die 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 die 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 die 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 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 3 Monitoring Results Results from the 2011 wedand monitoring effort indicate that the Dinkins Bottom Site is meeting mitigation goals in all proposed areas. 3.1 Hydrology Assessment Seven groundwater monitoring gauges are located on site. 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 2011 monitoring year indicate that five of the seven groundwater gauges (1,2,3,4 and 7) achieved die wetland success criteria of saturation for 10 consecutive days (5 (yo) during the growing season. Gauge 6 did not meet die 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 die wetland criteria attainment. 3.2 Vegetative Assessment The 2011 vegetation monitoring results indicated that the Site is meeting vegetative success criteria. The average site density is approximately 908 planted stems per acre, which exceeds the year three goal of 320 planted stems per acre. There is an average of 46 live planted stems per plot. There was a concern of too many Sweet Gum and Sycamore in plots 6, 8 and 9 so we performed a hack & squirt method in the fall of 2011 in order to dun some of these unwanted species. The results should show up in die 2012 Stem Count. Please refer to appendix 2 for more detailed information on the 2011 vegetation data. In summary, the Dinkins Bottom site has met the wetland and vegetation mitigation goals for monitoring year 3. 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 three and Appendix 3 for representative photographs.
