Biologists with the North Carolina Wildlife Resources Commission are familiar with habitat values in the area. These comments are provided in accordance with the provisions of the Fish and Wildlife Coordination Act (48 Stat. 401, as amended; 16 U.S.C. 661-667d) and the North Carolina Environmental Policy Act (G.S. 113A-1 through 113A-10; NCAC 25). The project is to construct a j-hook on the left bank to replace a wooden fish structwe lost during the 2004 floods. In addition, four large boulders are proposed downstream to provide fish habitat in an area just above the Highway 181 Bridge. This portion of the project may not occur unless approved by North Carolina Department of Transportation (NCDOT) due to nght-of--way issues related to the bridge. A preliminary site visit was conducted by this office and Mr. Bob Brown, Fish biologist on June 19, 2007. Mr. Kevin Barnett with the NC Division of Water Quality also attended the site visitation. Brown and Rainbow trout are known for this area of the Linville River. The activities proposed should provide increased fish holding habitats. Accordingly, we will not object to the project providing the activities are implemented so as not to cause bank or bridge instability. State-of--the-art natural channel design structures and techniques, including well placed and installed fiber logs, fiber matting, j-hooks, w-weirs, and root wads are preferred techniques as these methods tend to restore natural channel dimensions, including the natural thalweg. The following conditions are recommended for inclusion in permits and certifications for the project: • In stream work and land disturbance within the twenty-five (25) foot wide buffer zone are prohibited during the brown and brook trout spawning season of October 15 through April 15 to protect the egg and fiy stages of trout from off-site sedimentation during construction.

Where this is not possible or practicable, equipment used should be new or low-hour and well maintained. Spill containment equipment should be readily available during equipment work in channel. Where the project disturbs buffers, temporary or permanent native herbaceous vegetation should be established on all bare soil wrthm five (5} days of ground disturbing activities in the twenty-five (25} foot trout buffer to provide long-term erosion control. We encourage use of fiber matting. Onsite vegetation and materials may be used for stream bank stabilization when practicable. Restored banks should be replanted with autochthonous (native) plants like silky dogwood, rhododendron, dog hobble, red maple, silky willow, tag alder, black willow, sycamore, river birch, or other native woody species. We continue to have general water quality concerns about the Linville River associated with upstream activities and impacts. For this specific project, we recommend additional consultations with the NCDOT to determine if j-hooks, w-weirs or other natural design structures can enhance fish holding, natural channel habitats, and bridge stability. Thank you for the opportunity to review and comment on this project during the early planning stages. If you have any questions regarding these comments, please contact me at 336-769- WILD (9453).
