SUBJECT: Cavioli Project
New River, Alleghany County
Dear Ms. Amschler:
Biologists with the North Carolina Wildlife Resources Commission (NCWRC) reviewed an
application to stabilize 338 ft of the New River in Alleghany 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 New River is recognized by the NC Natural Heritage Program as the
South Fork New River and 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
Purple Wartyback (Cyclonaias tuberculata, NC Endangered), Logperch [Percina caprodes, NC
Threatened (T)], Mimic Shiner (Notropis volucellus, NC T), Eastern Hellbender
[Cryptobranchus alleganiensis, US Federal Species of Concern (FSC), NC Special Concern
(SC)], Mudpuppy (Necturus maculosus, NC SC), Spike (Eurynia dilatata, NC SC), Seep
Mudalia (Leptoxis dilatata, NC SC), Kanawha Minnow (Phenacobius teretulus, NC SC),
Kanawha Rosyface Shiner [Notropis sp. 1, NC Significantly Rare (SR)], Appalachia Darter
(Percina gymnocephala, NC SR), Pygmy Snaketail (Ophiogomphus howei, NC SR), Brook
Snaketail (Ophiogomphus aspersus, NC SR), and Splendid Clubtail (Gomphurus lineatifrons,
NC SR). It is likely that hellbenders are in the project footprint. Due to the sensitivity of these
species to fine sediments, it is essential that excellent erosion and sediment control be maintained
during the project.
The application proposes to stabilize an eroding reach of bank on the New River through sloping
the bank, planting native woody and herbaceous vegetation, and installing two in -stream rock

vanes. Most work will be done from the bank, but some instream access may be necessary for
proper installation of the rock vane.
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. Work should be performed during low flows. For the rock vane installation, we recommend
diverting flows around the work area especially at the bank tie in location to reduce the risk
of fine sediment liberation and loss.
4. NCWRC staff will likely survey the site before project construction for rare animals. We ask
that the project manager coordinate with Andrea Leslie (andrea.lesliegncwildlife.org) and
Lori Williams (lori.williamsgncwildlife.org) to ensure access to the site, and we ask that the
project manager reach out to them at least three weeks before construction begins.
5. 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.williamsgncwildlife.org) if
hellbenders are found.
6. To increase habitat diversity, we recommend incorporating stable woody debris into the
project design.
7. 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.
