SUBJECT: Walker WNCSI Project
Cove Creek, Watauga County
Dear Ms. Amschler:
Biologists with the North Carolina Wildlife Resources Commission (NCWRC) reviewed an
application to stabilize 2,002 ft of Cove Creek and temporarily impact 15 ft of stream in
Watauga County. I attended a site visit on January 27, 2022. Our comments on this application
are offered for your consideration under provisions of the Clean Water Act of 1977 (33 U.S.C.
466 et. seq.) and Fish and Wildlife Coordination Act (48 Stat. 401, as amended; 16 U.S.C. 661-
667d).
Wild trout should not be impacted by project activities, and a trout moratorium is not required for
the project. However, Cove Creek is recognized by the NC Natural Heritage Program as part of
the Watauga River Aquatic Habitat, rated Very High for the richness of rare species it contains.
The Eastern Hellbender (Cryptobranchus alleganiensis, US Federal Species of Concern, NC
Special Concern) is found in Cove Creek, and in order to avoid detrimental impacts to this
species it is important to use excellent erosion and sediment control on the project.
The application proposes to address unstable reaches of channel by installing a bankfull bench
and a series of in -stream structures including j-hooks, cross vanes, constructed riffles, toewood,
and boulder revetments. The project would be constructed between June and July 2022.
According to Adam Williams, a woody buffer of native plants of 15 ft in width will be
established. We strongly recommend that a native riparian buffer of at least 30 ft in width be
established and maintained.
Because hellbenders have been found in Cove Creek, NCWRC staff will conduct surveys of the
project area before construction.

We offer the following recommendations to minimize impacts to fish and wildlife resources:
I. Be vigilant with sediment and erosion control during site staging, construction, and cleanup.
Disturbed areas should be stabilized at the end of each day.
2. Work should be done at low flows, and flows diverted around in -stream work areas to
minimize fine sediment loss to the stream. Work should be performed from the banks as
much as possible, and instream equipment use be minimized.
3. Any erosion control matting used should be free of nylon or plastic mesh, as this type of
mesh netting frequently entangles wildlife and is slow to degrade, resulting in a hazard that
may last for years.
4. The project manager should reach out to Lori Williams (lori.williamsgncwildlife.org ) and
Andrea Leslie (andrea.lesliegncwildlife.org) at least three weeks before construction begins
so that hellbender surveys can be conducted.
5. Native rocks potentially used by hellbenders should be left undisturbed during construction
activities. These rocks are typically large flat rocks at least a foot in diameter.
6. Project staff should be on site during in -stream activities to watch for hellbenders. If animals
are disturbed during construction, they should be captured in a bucket and moved away from
the area of disturbance. Please notify Lori Williams if hellbenders are found.
7. We recommend that a woody buffer as wide as possible (we recommend at least 30 feet) be
planted on the stream as infrastructure allows in order to ensure project success. A wide
forested buffer can ensure greater bank stability, filter overland pollutants, and provide
habitat for birds and other wildlife.
Thank you for the opportunity to review and comment on this project. Please contact meat
