sections (3 riffles and 3 pools) Overall, the stream channel bed form and banks are stable, pool depths and widths remain consistent with the constructed geometry, and bed features indicate no significant aggradation or degradation Based on the cross - sections, longitudinal profile and visual observations, the channel dimensions have not changed significantly compared to as -built conditions and the channel classifies as a Rosgen E -type stream Wetland Hydrology Assessment Success criteria for wetland hydrology require that restored wetland areas be inundated or saturated by groundwater within 12 inches of the ground surface for a period of time during the growing season NCEEP Contract No D06066 -A 1 2012 Monitoring Report THIS PAGE INTENTIONALLY LEFT BLANK NCEEP Contract No D06066 -A 2 2012 Monitoring Report CHOWAN RIVER BASIN HERTFORD (CU03010204) COUNT`( ;2581 omo y �{i p — Z O ,freestw¢o ?

BLANK NCEEP Contract No D06066 -A 4 2012 Monitoring Report consistent with other wetlands located in similar settings The growing season in Hertford County begins on March 28 and ends on November 7 (225 days) In order to achieve hydrologic success, saturation within 12 inches of the ground surface is required for between 12 and 28 consecutive days (5 to 12 5 percent) The results of the Year 5 hydrologic monitoring indicate that all gauges exhibited saturation within 12 inches of the ground surface for at least 7 6 percent of the growing season The period of saturation ranges from 17 to 57 days or (7 6 and 25 3 %) with an average of 25 6 days (114%) of the growing season Based on Year 5 hydrologic monitoring, success criteria for wetland hydrology has been achieved 2.0 PROJECT BACKGROUND 2.1 Project Objectives Site restoration activities included the excavation of a new stream channel, limited floodplam excavation, removal of stumps and debris, existing channel backf►]ling, on -site drainage ditch removal, and final grading and soil preparation within the adjacent floodplam These activities were proposed in order to reintroduce surface water flood hydrodynamics from a 0 9- square mile watershed along the newly restored length of stream and floodplam The new channel was constructed to reflect regional stream characteristics and accommodate bankfull flows Characteristic wetland soil features, groundwater wetland hydrology, and hydrophytic vegetation communities are expected develop in areas adjacent to the constructed channel Wetland and adjacent slope soil surfaces were restored and the Site reforested to promote riparian and upland slope hardwood communities Plant community associations were designed to mimic various indigenous communities described by Schafale and Weakley (1990), including Coastal Plain Levee Forest, Cypress -Gum Swamp, Mesic —Mixed Hardwood Forest, and Coastal Plain Small Stream Swamp Specific ecological benefits anticipated as a result of on -Site restoration activities are as follows • Stream channel restoration will reintroduce stable bankfull dimension, pattern, and profile along restored stream reaches, which is expected to enhance lotic habitat quality and stream function • Floodplam excavation adjacent to restored streams will restore the characteristic flood regime, as well as provide a lateral hydrologic input to restored wetland areas adjacent to the UT and within the greater Cutawhiskie Creek floodplam • Restored and enhanced wetland areas will help to improve water quality via nutrient removal, increase local vegetative biodivers►ty, provide wildlife habitat, and serve as a forested corridor, linking the Site with adjacent forested areas 2.2 Project Structure, Restoration Type, and Approach The primary restoration features within the Site include the UT to Cutawhiskie Creek and approximately 11 9 acres of drained, hydric soils The UT had been dredged and straightened, such that it did not exhibit stable dimension, pattern, and profile features Side -cast material (spoil piles) from dredging was deposited along the west bank of the former channel A moderate headcut (approximately 2 foot drop in elevation over 20 linear feet of stream channel) was observed near the upstream (north) extent of the Site boundary, indicating vertical instability Due to its high level of entrenchment caused by dredging, large flooding events were confined within the former channel NCEEP Contract No D06066 -A 5 2012 Monitoring Report On -site restoration activities provide the

forest, pastureland, roadside shoulders, and residential lots Row crops including soybeans, cotton, and corn are actively cultivated on the Site and surrounding areas The Site is immediately adjacent to active rowcrop agriculture and timberland There is no livestock or poultry production in the vicinity Timber is actively harvested from adjacent forested areas A large, contiguous bottomland hardwood stand was harvested dust west of the Site along the Cutawhiskie floodplain in the spring of 2006 The Site encompasses approximately 22 9 acres of primary and secondary floodplain associated with Cutawhiskie Creek The Site includes a UT that flows into Cutawhiskie Creek from the north (Figure 1) Portions of the Site had been logged prior to restoration activities, while other areas within the Site were actively managed for timber or agricultural production Prior to restoration, the Site vegetation was generally characterized by NCEEP Contract No D06066 -A 6 2012 Monitoring Report bottomland hardwood forests along un- logged areas on the Cutawhiskie Creek floodplam and low terraces, row crops including soybeans and corn, and successional communities associated with cut -over

areas be inundated or saturated by groundwater within 12 inches of the ground surface for a period of 5 to 12 5 percent of the growing season The growing season in Hertford County begins on March 28 and ends on November 7 (225 days) In order to achieve hydrologic success, saturation within 12 inches of the ground surface is required for between 12 and 28 consecutive days during the growing season (5 to 12 5 percent) The results of the Year 5 hydrologic monitoring indicate that all gauges exhibited saturation within 12 inches of the ground surface for at least 7 6 percent of the growing season (Appendix C) The average saturation period for all gauges was 25 6 days (114%) ranging from 17 to 57 days (7 6 and 25 3 %) Figure 3 (Appendix C) shows a comparison of 2012 monthly rainfall to historical precipitation for Hertford County The figure shows average rainfall data collected between 1948 and 2012 and compares 30 percent and 70 percent of all observations with the actual 2012 monthly rainfall amounts to determine average Monthly rainfall amounts were below the 30`h percentile during four months of the growing season Table X summarizes wetland hydrology criteria for Year 5 monitoring 4.0 METHODOLOGY No unavoidable deviations from initially prescribed methodologies were implemented as part of Year 5 monitoring activities 5.0 REFERENCES Lee, Michael T, R K Peet, S D
