South Fork New River, Ashe County
Dear Ms. Fuemmeler:
Biologists with the North Carolina Wildlife Resources Commission (NCWRC) reviewed an
application to stabilize 130 feet of the South Fork New River in Ashe County. 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).
Project activities should not impact wild trout and do not need to be avoided during the trout
moratorium. However, the South Fork New River is recognized by the NC Natural Heritage
Program as the South Fork New River Aquatic Habitat, rated Exceptional for the richness of rare
species it contains. Rare and listed species found in the river in the vicinity of the project include
Green Floater [Lasmigona subviridis, US Federal Species of Concern (FSC), NC Endangered],
Seep Mudalia (Leptoxis dilatata, NC Threatened), Eastern Hellbender [US FSC, Special Concern
(SC)], Spike (Elliptio dilatata, NC SC), and Kanawha Darter [Etheostoma kanawhae, NC
Significantly Rare (SR)]. These rare species are especially sensitive to sediment, and excellent
erosion and sediment control is essential to minimize impacts to these species.
The application proposes to stabilize an eroding reach of bank through sloping the bank, planting
native woody and herbaceous vegetation, and installing one in -stream rock vane. Most work will
be done from the bank, but some instream access may be necessary for proper installation of the
rock vane. We support this project, as it should address bank erosion and reduce instream
sediment.

We offer the following recommendations to minimize impacts to the aquatic community:
1. In -channel work should be accomplished as quickly as possible and vigilance used in
sediment and erosion control during site preparation, construction, and clean up. Disturbed
areas should be seeded, mulched and/or matted as soon as possible, preferably at the end of
each work day.
2. 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.
3. For the rock vane installation, we recommend diverting flows around the work area
especially at the bank tie in locations to reduce the risk of fine sediment liberation and loss.
4. Shelter rocks potentially used by Hellbenders should be left undisturbed during construction
activities. Shelter rocks are typically large flat rocks at least a foot in diameter. 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 (lori.williamskncwildlife.org ) if
hellbenders are found.
5. We recommend that a woody buffer of at least 30 feet be planted on the stream banks as
infrastructure allows in order to ensure project success.
