The MDCRS is a riparian system in the Upper Yadkin Pee-Dee River Basin (3040101 8-digit cataloging unit) in Yadkin County, North Carolina. The site’s natural hydrologic regime had been substantially modified through the relocation and straightening of the existing stream channels, livestock impacts, and clearing of riparian buffer. This completed project will restore streams impacted by pasture and agriculture to a stable headwater ecosystem with a functional riparian buffer and floodplain access. The MDCRS is protected by a 40.2 acre permanent conservation easement, held by the State of North Carolina. The site is located approximately 0.5 miles north of East Bend, NC. Specifically, the site is 0.2 mile north on Shady Grove Church Road (SR-1538) from its intersection with Shoals Road (SR-1546). The North Carolina Ecosystem Enhancement Program (NCEEP) published the Upper Yadkin Pee-Dee River Basin Restoration Priorities (RBRP) in 2009. The project’s 14 digit CU (03040101110070, Grassy Creek and Horne Creek) was identified as a Targeted Local Watershed (TLW) in the RBRP. The goals and priorities for the MDCRS are based on the information presented in the Upper Yadkin Pee-Dee River Basin Restoration Priorities: maintaining and enhancing water quality, restoring hydrology, and improving fish and wildlife habitat (NCEEP, 2009). The project will support the following basin priorities: - Managing stormwater runoff - Reducing fecal coliform inputs - Improving/restoring riparian buffers - Reducing sediment loading - Improving stream stability - Reducing nutrient loading - Excluding livestock and implementing other agricultural BMP’s - Protecting high-resource value waters, including water supply watershed designated waters The project is also located in the Ararat River Local Watershed Plan (LWP) study area. The Ararat River was designated a LWP Study Area due to poor water quality and aquatic habitat degradation issues, as well as the presence of good candidate sites for stream restoration in rural catchments (NCEEP, 2009). The stressors within the Ararat River LWP are erosion and sedimentation, missing or degraded riparian buffers, stormwater runoff, and nutrient and fecal coliform “hot spots” (NCEEP, 2013). The goals for the project are to: - Restore channelized and livestock-impacted streams to stable C and B type channels. - Restore a forested riparian buffer to provide bank stability, filtration, and shading. The project goals will be addressed through the following objectives: - Relocate or stabilize channelized and/or incised streams to connect to a floodplain or floodprone area. - Install a cross-section sized to the bankfull discharge. - Create bedform diversity with pools, riffles, and habitat structures - Fence out livestock to reduce nutrient, bacterial, and sediment impacts from adjacent grazing and farming practices to the project tributaries - Plant the site with native trees and shrubs and an herbaceous seed mix. Project construction was completed in December 2019 and project planting was completed in March 2020. The 13,505 linear feet of streams at MDCRS were enhanced and restored by re-meandering the stream and by tying the bankfull elevation to the historic floodplain where feasible. The entire site was planted to Mill Dam Creek Restoration Site KCI Associates of NC, PA DMS Project #97136 2 MY03 Monitoring Report establish a forested riparian buffer. The site was constructed as designed with only minor modifications from the design plan. These modifications generally consisted of slight adjustments in the alignment and spacing of riffles/pools due to bedrock encountered during construction. Several areas of additional bank stabilization were also installed. On February 6, 2020, shortly after construction was completed and before woody stems had been planted, the site received over 6 inches of rain in a 24 hour period. This storm caused significant damage to portions of the site and required repairs to be completed in March 2020. These repairs mainly involved repair of bank erosion through the installation of live lifts, removal of aggradation from the stream channel, and regrading areas of floodplain scour. Approximately 500 cubic yards of topsoil were also brought in and placed on the floodplain in areas of severe floodplain scour. Additional heavy precipitation events took place in the fall of 2020. These events cause isolated areas of bank erosion and the movement of a boulder sill. In July 2021, these areas were repaired by sloping back the eroding banks, reapplying coir matting, installing new live stakes, and repairing the damaged boulder sill on UTHC 4-1. The monitoring components were installed in March/April 2020. Five automatically recording pressure transducer stream gauges that take a reading every 10 minutes were installed: one each in the upper third of T1A, T5A, and T8A to document flow within those reaches, and two on UTHC to record the occurrence of bankfull events. Cameras were installed in the vicinity of each of the flow gauges and set to record a short video once a day to provide additional verification of flow. Two automatically recording pressure transducer groundwater monitoring gauges were installed within pre-existing wetlands on the site to monitor wetland hydrology and ensure the existing wetlands on the site are not adversely affected by the restoration project. One of these gauges is located in the vicinity of the pre-existing wetland on the left bank of T7 and the other is located within the pre-existing wetland on the right bank of T8. To determine the success of the planted mitigation areas, eighteen 10 m x 10 m permanent vegetation monitoring plots were established. An additional twelve 10 m x 10 m random temporary vegetation monitoring plots are sampled during each monitoring year as well. The locations of the planted stems relative to the origin were recorded within the permanent plots and the species and height of each planted stem were recorded for all plots. Any volunteers found within the plots were grouped into size categories by species, but separate from the planted stems. Twelve permanent photo reference points were established and are taken annually. Thirty-two permanent cross-sections (24 riffle cross-sections and 8 pool cross-sections) were also established and a detailed longitudinal profile of the stream was taken. Wolman pebble counts were performed at all of the riffle cross-sections. The cross-section measurements are repeated in monitoring years 1, 2, 3, 5, and 7, but the longitudinal profile will only be repeated if there are concerns about bed elevation adjustments. Reports will be submitted to DMS each year. SUCCESS CRITERIA Vegetative success criteria for the stream mitigation is 260 woody stems/acre after five years, and 210 woody stems/acre after seven years. Trees in each plot must average seven feet in height at Year 5 and ten feet in height at Year 7. Volunteer species must be present for a minimum of two growing seasons and must be a species from the approved planting list to count toward vegetative success. A single species may not account for more than 50% of the required number of stems within any plot. A minimum of four bankfull events must also be recorded during the monitoring period. All project streams must show a minimum of 30 continuous days of flow within a calendar year (assuming normal precipitation) A “normal” year is based on NRCS climatological data for Yadkin County with the 30th and 70th percentile thresholds as the range of normal, as documented in the USACE Technical Report “Accessing and Using Meteorological Data to Evaluate Wetland Hydrology, April 2000.” Bank height ratios (BHR) should not exceed 1.2 and the entrenchment ratios (ER) should be 2.2 or greater. BHR and ER at any measured riffle cross-section should not change more than 10% from the previous Mill Dam Creek Restoration Site KCI Associates of NC, PA DMS Project #97136 3 MY03 Monitoring Report condition during any given monitoring interval (e.g. no more than 10% between years 1 and 2, 2 and 3, 3 and 5, or 5 and 7). Visual assessments will also be used to identify problem areas. MONITORING RESULTS The MY03 vegetation monitoring was conducted between August 1 and 4, 2022. All of the 30 vegetation monitoring plots had greater than 260 woody stems/acre. The average stem density across all the surveyed plots is 805 planted stems/acre. Including volunteers, the site averaged 1,209 stems/acre. A supplemental planting of the wetland located at the top of T3 was completed on October 25, 2021. Due to the prolonged periods of saturation in this area, as well as the rapid growth of the herbaceous vegetation in MY01, the majority of the planted woody stems in this wetland did not survive. Thirty one-gallon size containerized trees were planted within this area. Species were chosen that could best tolerate extended periods of saturation. Please see Appendix C – Vegetation Plot Data for a list of the species and quantities that were planted. Invasive species were treated on the site in July 2022. This treatment focused on Chinese privet growing in areas of existing woodline that were not cleared as part of construction. The MY03 cross-sections survey took place between January 9 and 12, 2023. None of the 32 cross-sections had a bank height ratio greater than 1.2. Two of the 32 cross-sections have an entrenchment ratio less than 2.2. These two cross-sections are XS6 and X12 and both are located in enhancement reaches where the stream work that was completed consisted of cutting a floodplain bench along one bank. Neither reach shows signs of instability and these lower than desirable entrenchment ratios are remnants of the pre-project conditions. The heavy precipitation events that took place in 2020 have caused some cross-sections to shift from their baseline or MY01 alignment. Two notable examples of this are XS8 and XS13. Since the repairs that took place in MY02, these cross-sections have remained stable and not shifted any further. Further movement within these areas is not anticipated. There are two cross-sections that have shown significant adjustment between MY02 and MY03. These cross-sections (XS24 and 25) are both located on the lower section of T6. The stream bed at XS24 (riffle) had aggraded by approximately 0.4’ between baseline and MY01, but since then it has remained relatively stable while the stream banks have continued to aggrade. XS25 downcut by approximately 0.5’ between the baseline and MY01 surveys before starting to aggrade. Between MY01 and MY02, it aggraded by approximately 0.5’, returning to the baseline stream bed elevation. Between MY02 and MY03 it aggraded an additional 0.5’. T6 is a small stream with an un- stabilized section above the project reaches. Cattle have access to this un-stabilized reach and so it provides a major source of sediment to the project streams. These fluctuations in the bed and bank elevation are part of the natural processing of the heavy sediment load through the system. Despite the changes in elevation, the stream alignment has remained stable and there is no evidence of bank erosion through this reach. KCI will continue to monitor this area closely but does not believe that these changes represent a threat to project success. During 2022, the stream gauge on UTHC-1 recorded 9 bankfull events, while the stream gauge on UTHC- 3 recorded 5 bankfull events. All three of the reaches being monitored for flow demonstrated more than 30 consecutive days of flow during 2022. The gauge on T1A recorded a maximum of 34 consecutive days. The gauge on T5A recorded flow for 303 consecutive days (the entire period of record for 2022) and the gauge on T8A recorded a maximum of 217 consecutive days. The gauge data was further verified by the cameras on site. Based on the video recordings obtained from the cameras, T1A had a maximum of 104 consecutive days of flow, T5A had a maximum of 114 consecutive days of flow, and T8A had a maximum of 92 consecutive days of flow. The differences between the number of days of flow documented by the cameras versus the gauges is largely due to extended periods of time during which the cameras were obscured by vegetation during the growing season and periods of time when the stream flow was at levels too low for the gauges to record. Mill Dam Creek Restoration Site KCI Associates of NC, PA DMS Project #97136 4 MY03 Monitoring Report On August 15, 2022, the IRT met on-site to evaluate the site conditions and see the results of the July 2021 repairs. At this meeting the IRT requested that KCI add live stakes to the outer bend areas that were repaired. This work will be completed in February 2023. The IRT also requested that KCI keep an eye on the structures on site and the invasives. While no areas of thick invasives were noted, there were scattered individuals of Chinese privet, mainly in areas of the site that had existing woodlines. Similarly, none of the structures on site had failed, but a few were seen to be potentially starting to pipe. KCI will continue to monitor these areas to ensure they don’t become a threat to project success. Overall the site is functioning as designed with no major problem areas or threats to project success identified during MY03. REFERENCES NCDENR, Ecosystem Enhancement Program. 2009.

The site was damp from a previous rain and the weather was mild and slightly overcast. The group walked most of the restoration portions of T6 and UTHC3. We also drove to the top of the site where we walked T1A and T1. The comments from the site walk are listed below. - Pay attention to invasives. There were no areas of thick invasives, but there were some scattered in the easement around the areas of the site that had not been cleared for construction. - In some portions of the buffer, the sycamores are the most notable tree. Watch the diversity data from the veg plots and supplement if necessary. - Take photos of the crossings, from the stream and include those in future monitoring reports. - Overall, the site is well vegetated with thick herbaceous vegetation. Some areas of Priority 2 restoration have less vegetation on the floodplain/benches. Watch those areas for future vegetation vigor. - A couple of structures were found to be piping. Pay attention to those to make sure the structures are still maintaining function and not degrading. - Some of the previously repaired areas from flood damage were lacking in live stakes. KCI will add live stakes to those areas during this upcoming dormant season. - There was a previous encroachment area near the bottom of T1, where the landowner had driven inside the easement as short cut between two gates instead of going outside of the easement. We checked this area during the site walk and it did not appear that this was still an issue, but we will continue to pay attention to this area and document any future encroachments. These comments were all discussed at the site walk and this meeting memo will be included in the MY03 monitoring report. Generally, the site was viewed positively, with the stream and buffers all looking healthy and functioning. The meeting ended around 3pm.
