Please give a brief project description below. * The proposed work is intended to improve the health of the stream ecosystem by improving channel stability and habitat quality, along with improving riparian and streamside vegetation conditions. This will be accomplished with the construction of instream structures using trees found on site fashioned in the channel to protect eroded stream banks and create high quality aquatic habitat features. The desired condition is to have high quality riparian areas and aquatic habitat features that maintain hydrologic function, floodplain connectivity, enhance stream stability, and minimize erosion. The proposed action is needed at this time, at these locations, because taking no action would lead to further erosion and sedimentation which, in turn, would cause further damage to aquatic habitat and the maintenance of state designated uses. The following channel enhancement and stabilization techniques are planned in this reach to improve degraded conditions and reverse the trend to improving conditions: 1) With a medium sized trackhoe construct channel features, e.g. point bars and floodplain (bankfull benches) where appropriate. Access for the equipment would be from a Forest Service road and off -road on the floodplain without construction of a road bed. Only vegetation would be cleared for equipment access and any compaction would be obliterated as the equipment leaves the area and access would be blocked. 2) Fell live trees from within 100 feet of the stream and incorporate large wood structures into the channel at designed locations to enhance channel stability and aquatic habitat diversity, e.g. riffles and pools. 3) Erosion control measures would be implemented on all disturbed soil. Please give a couple of dates you are available for a meeting. 1 /21 /2021 1 /28/2021 Please attach the documentation you would like to have the meeting about.

Signature Submittal Date 1/14/2021 Moccasin Creek Stream Enhancement Project Uwharrie Ranger District, National Forests in North Carolina Submitted by: Brady Dodd, NFsNC Hydrologist, April 2020 & January 2021 Existing Condition: The Moccasin Creek drainage is within the Outlet Uwharrie River Watershed (Hydrologic Unit Code 030401030505) in the Badin Lake Recreation Area (Figure 1). This area of Moccasin Creek is a priority for restoration and enhancement because there is a need to restore hydrologic function and aquatic habitat within these headwater reaches and reduce sedimentation to downstream reaches of Moccasin and McLeans Creeks, both streams classified by the state as Class C, WS-IV water supply use. .Moccasin Creels Stream Enhancement Project - Project Area inclusn-e of Reset on m ] 1%I ccasin -Fnnhe Sale?u•eas I-V Fmtn ngi 4 r A .� ' r-WA ARRlE 1 I.4 , Project Area :.r r � i � r � �. --•N A T 1 N A I-� \_ �� F O R E S I t I Figure 1.

Map of enhancement project stream reaches. This stream network of Moccasin Creek extends approximately 3 miles from the Forest Service Road FS597 crossing downstream to just below FS544 at the junction with West Branch, a drainage area of 2.44 square miles (Figure 2). The channel is a Rosgen "C" stream type, experiencing a degraded condition/function in stream ecosystem health because of past management activities, including tree harvest in the riparian area, farming, increases in stream peak flows from forest roads, and loss of large woody debris. These influences have caused channel down -cutting and a loss of floodplain accessibility during frequent flooding (25-year flood and less), resulting in excessive channel bank erosion (Figure 3). Evidence of recent gold panning was found on the stream bank, but this activity appears to be a small contributor to erosion. Figure 3. Photo of typical stream channel condition in Moccasin Creek. Moccasin Creek Stream Enhancement Project 2021 2 1 P a g e Proposed Action: Based on field assessments of stream conditions, erosion and sedimentation are the largest stressors on the aquatic environment. The proposed work is intended to improve the health of the stream ecosystem by improving channel stability and habitat quality, along with improving riparian and streamside vegetation conditions. This will be accomplished with the construction of instream structures using trees found on site fashioned in the channel to protect eroded stream banks and create high quality aquatic habitat features. The desired condition is to have high quality riparian areas and aquatic habitat features that maintain hydrologic function, floodplain connectivity, enhance stream stability, and minimize erosion. The proposed action is needed at this time, at these locations, because taking no action would lead to further erosion and sedimentation which, in turn, would cause further damage to aquatic habitat and the maintenance of state designated uses. The following channel enhancement and stabilization techniques are planned in this reach to improve degraded conditions and reverse the trend to improving conditions: 1) Using Regional Curve data (Appendix A) for the proposed channel dimensions are as follows: a. Moccassin Creek at confluence with McLeans Creek (Sites 10-20), 2.44 square mile drainage: i. Bankfull Cross -Sectional Area: 39.3 feet2 ii. Bankfull Discharge: 169.2 cfs iii. Bankfull Width: 17.4 feet iv. Bankfull Mean Depth: 2.0 feet b. Moccasin Creek upstream reaches (Sites 1-9 & 21-28), 0.9 square mile drainages: i. Bankfull Cross -Sectional Area: 19.9 feet2 ii. Bankfull Discharge: 82.5 cfs iii. Bankfull Width: 11.4 feet iv. Bankfull Mean Depth: 1.45 feet Proaosed chanizes in several cross -sections and lonizitudinal Drofile are Dresented in Appendix B. 2) With a medium sized trackhoe construct channel features, e.g. point bars and floodplain (bankfull benches) where appropriate. Access for the equipment would be from a Forest Service road and off -road on the floodplain without construction of a road bed. Only vegetation would be cleared for equipment access and any compaction would be obliterated as the equipment leaves the area and access would be blocked. 3) Fell live trees from within 100 feet of the stream and incorporate large wood structures (Figures 5 - 6) into the channel at designed locations to enhance channel stability and aquatic habitat diversity, e.g. riffles and pools.
