sections Overall, the stream channel bed form and banks are stable and have not changed significantly compared to as -built conditions n Although the reach meets the criteria for success, beaver are abundant in the area and have persistently recolonized the Site after prior removal efforts The beaver are active with dams above and below the Site as well as within the Site boundaries at the upper 0 end They were removed most recently in late 2010 and re- established dams in 2011 As per the North Carolina Ecosystem Enhancement Program another removal effort has been contracted with monthly monitoring scheduled for the Site until closeout The beavers presence has altered the function of the stream Instead of a flowing stream, parts of the site are characterized as a lentic system The stream has experienced limited flow in the summer months promoting vegetation growth in the channel This O condition has been caused by a combination of factors including multiple dry summers, beaver dams above the Site, and the low slope of the stream channel Morntonng Year 8 (2011) 1 December 2011 Key Branch Stream and Wetland Restoration (NCEEP Project 206) Anson County NC 1 0 INTRODUCTION 1 1 Project Description The Site encompasses 118 acres and is located in Anson County between Lower White Store Road (SR 1252) to the west and Mineral Springs Church Road (SR 1240) to the east (Figure 1) 12 Purpose In order to demonstrate successful mitigation, the Site must be monitored for a minimum of five years or until approved for close -out by the regulatory agencies Success criteria are based on federal and state guidelines for stream and wetland mitigation (USACE 2003) Criteria for wetland hydrologic conditions, restored stream channel stability, and vegetation survival are included in this document The following report describes the monitoring results for groundwater hydrology, stream channel stability, and planted vegetation during the 2011 growing season at the Key Branch Restoration Site 1 3 Project History Fall 2003 Construction November 2003 Site Planted March -

wetlands Areas meeting hydrology between 5 percent and 12 5 percent of the growing season can be classified as wetlands depending upon such factors as the presence of wetland vegetation and hydric soils If wetland parameters are marginal as indicated by vegetation and hydrological monitoring, consultation with EEP personnel and regulatory agencies will be undertaken to determine the extent of wetland restoration in these areas A jurisdictional determination will be performed in early 2012 to determine the extent of wetland areas at the Site The growing season in Anson County begins March 11 and ends November 23 (258 days) These dates correspond to a 50 percent probability that air temperatures will not drop below 28 °F or lower after March 22 and before November 15 Minimum wetland hydrology is required for at least 12 5 percent of this growing season, for Anson County, 12 5 percent of the growing season equals 30 consecutive days 22 Hydrologic Description On -site hydrologic monitoring was initially facilitated by fourteen, continuously recording groundwater gauges located throughout the wetland restoration area (Figure 2) One of the gauges could not be located in 2009, reducing the number to 13 During the 2011 monitoring season, groundwater data was collected monthly from all monitoring gauges 23 Results of Hydrologic Monitoring 2 3 1 Site Data The maximum number of consecutive days that groundwater was within 12 inches of the surface was determined for each groundwater gauge This number was converted into a percentage of the 258 -day growing season The results are summarized in Table 1 and indicate that all gauges exhibited saturation for at least 6 2 percent of the growing season The average saturation period for all gauges was 60 1 days (23 3 %) ranging from 16 to 107 days (6 2 and 41 4 %) Ten of the thirteen gauges met success criteria by maintaining saturation for more than 30 days The remaining three gauges maintain saturation for 5 to 12 5 percent of the growing season C Appendix B contains hydrographs of the daily water depth recorded for each groundwater gauge In general, groundwater levels show a typical pattern of flooding or Monitonng Year 8 (2011) 3 December 2011 Key Branch Stream and Wetland Restoration (NCEEP Project 206) Anson County NC high water table during the winter to early spring, followed by a summer and early fall drawdown period, punctuated by peaks of associated precipitation events Table 1 Key Branch Hydrologic Monitoring Results Monitoring , � � Success Abe D Number�of Days" Gauge 9 <5% 5-125% >12 5% Actual % ' Gauges mega ODates Success Cntena KBMG1 ✓ 391 March 11 — 101 June 19 KBMG2 ✓ 232 March 9 60 KBMG3 ✓ 232 March 9 60 KBMG5 ✓ 178 March 11 — 46 April 25 KBMG6 ✓ 41 4 March 11 — 107 June 25 KBMG7 ✓ 391 March 11 — 101 June 19 KBMG8 ✓ 193 March 11 — 50 April 29 KBMG9 ✓ 159 March 11 — 41 April 20 KBMG10 ✓ 9 3 March 27 — 24 April 19 KBMG11 ✓ 8 9 March 17 — 23 April 18 KBMG12 ✓ 407 March 11 — 105 June 23 KBMG13 ✓ 6 2 March 30 — 16 April 14 KBMG14 ✓ 182 July 17 — 47 August 30 2 3 2 Climatic Data Figure 3 shows a comparison of 2011 monthly rainfall to the historic range of normal precipitation for Wadesboro, NC (State Climate Office of NC, CRONOS Database) The historic range of normal precipitation is determined from rainfall data collected between 1948 and 2011 Figure 3 depicts the range of normal rainfall between the 30 percent and 70 percent of all observations compared to the actual 2011 monthly rainfall amounts Monthly rainfall amounts were below the 30th percentile during five months of the growing season The months of July, September and October received average rainfall, while May received above average rainfall The total rainfall of 25 36 inches for the year Morntonng Year 8 (2011) 4 December 2011 Key Branch Stream and Wetland Restoration (NCEEP Project 206) Anson County NC through November is below the historic average of 41 52 inches for the same time period 3 0 STREAM ASSESSMENT 31 Stream Monitoring Requirements The Site stream monitoring plan requires an assessment of geomorphologic parameters in keeping with the U S Army Corps of Engineers (USACE) "Stream Mitigation Guidelines', dated April 2003 The monitoring plan includes the protocol and provisions for providing photographs and channel stability analysis on a yearly basis Global Positioning System (GPS) equipment was used along with metal detectors to locate existing cross section pins Twelve permanent cross - sections were located and surveyed A 3,000 foot longitudinal profile of the restored channel was surveyed beginning near station 13 +00 (Figure 2 A -B) Bank stability and overall condition of the stream was assessed during the cross - section and longitudinal profile surveys Lateral photographs were collected at each cross - section (Appendix D) A stream monitoring gauge located in the channel provides stream flow elevation data to verify bankfull events 32 Post Construction Conditions The project involved the construction of approximately 6,200 linear feet of channel using a Priority 1 restoration approach Engineered structures included -hook vanes, log vanes, rock cross vanes, rootwad revetments, step pools, and additional bank sloping A step pool was installed at the beginning and end of the reach to maintain grade A rootwad complex was installed in the apex of numerous bends with cover logs for habitat Cross vanes, log vanes, and -hook vanes were installed throughout the reach to direct higher flow velocities into the center of the channel Throughout the entire reach the inner berm was maintained, enhanced, or created as channel modifications were made 33 Results of Stream Monitoring The mitigation plan stipulated the placement of a permanent monitoring cross - section every 20 bankfull widths A total of twelve cross sections were surveyed Three cross - sections were identified as riffles, cross sections 5, 10, and 12 For this report only cross sections containing riffles were used in the comparison of channel morphology presented below in Table 5 Data shown in Table 6 includes all cross sections surveyed along the reach Overall the stream survey data indicates a stable channel with very little lateral or vertical movement The stream gauge registered seven bankfull events during the 2011 monitoring year (March 28, April 1, April 6, April 10, May 12, May 15 and May 28), further demonstrating stream stability Bankfull Events for the eight year monitoring period are presented in Table 2 Monitonng Year 8 (2011) 5 December 2011 Key Branch Stream and Wetland Restoration (NCEEP Project 206) Anson County NC D Table 2 Bankfull Events Year s Evaluation Method s Number of Events �Mo'nitoni4Firm 2004 USGS Goose Creek Gauging Station 3 NCDOT 2005 N/A N/A NCDOT 2006 Stream Gauge 1 2 The Louis Berger Group 2007 Stream Gauge 1 and 2 N/A The Louis Berger Group 2008 N/A N/A Atkins 2009 N/A N/A Atkins 2010 Stream Gauge 1 3 Atkins 2011 Stream Gauge 1 7 Atkins 0 Although the restored reach met criteria for success, beaver are abundant in the area and have persistently recolonized the Site after prior removal efforts Beaver are active with dams above and below the Site as well as within the Site boundaries at the upper end (Figure 2, Appendix A) They were removed most recently in late 2010 and re- established dams in 2011 As per the North Carolina Ecosystem Enhancement D Program another removal effort has been contracted with monthly monitoring scheduled for the Site until close out The beavers presence has altered the function of the stream Instead of a flowing stream, parts of the site are characterized as a lentic system The stream has experienced limited flow in the summer months promoting vegetative growth in the channel This condition has been caused by a combination of factors including multiple dry summers, beaver dams above the Site, and the low slope D of the stream channel Monitonng Year 8 (2011) 6 December 2011 C� 1, Table 3 Baseline Stream Data Summary Kev Branch Stream and Wetland Restoration Site -
