This letter is to request Section 401 Water Quality Certification from the North Carolina
Division of Water Quality for U.S. Forest Service project: Little Buck Creek Dam
Decommissioning and Stream Improvements Proiect. Located on the Nantahala National Forest,
Tusquitee Ranger District in Clay County, North Carolina, this project is situated on Little Buck
Creek and Buck Creek, in the Little Tennessee River Basin.
The following three sites are proposed for rehabilitation and stabilization:
Site A: The Forest Service is proposing to remove the earthen dam structure and restore natural
drainage patterns and eliminate a high hazard dam. Recent inspections show indications of
structural and seepage problems with the dam. This project is located just upstream from two
road crossings which may be affected in the event of a dam failure. Approximately 500 feet of
stream restoration would be required from the dam to the inlet of the existing reservoir.
Additionally, restoration of the stream channel at the pond site would reconnect approximately
0.2 mile of streams by eliminating an aquatic organism passage barrier.
Site B: Removal of the log check dam in Little Buck Creek and reconstruction of the stream
bank would stabilize the stream channel and restore it to a natural condition.
Site C: Installation a boulder vane structure in lower Buck Creek would direct stream flow away
from the eroding stream bank adjacent to the Forest Service Road and prevent further erosion.
This project would improve water temperatures within the Buck Creek watershed and provide
improved habitat conditions for the native aquatic species within the watershed by restoring the
stream water temperatures and aquatic passage, and increasing stream habitat complexity.
A copy of the 404 permit application has also been sent to the N.C. Wildlife Resources
Commission and U.S. Fish and Wildlife Service for review. An Erosion and Sediment Control
Plan will be submitted to NC Division of Land Quality since disturbed area is greater than one
acre.
Enclosed are the following materials:
Five copies of the Pre - Construction Notice (version 1.3), application for 404 permit
(Nationwide Permit #27), with the Letter of Delegation of Authority
Five copies of the vicinity map and site plans for the project
Caring for the Land and Serving People Printed on Recycled Paper
• Five copies of the signed NEPA documentation (Decision Memo) for the project
• A check made payable to the Division of Water Quality for $570.00 since the length of
stream channel impacts is more than 150 feet

3. Project Description
3a. Describe the existing conditions on the site and the general land use in the vicinity of the project at the time of this
application:
Site A: The earthen dam is located on National Forest System lands in Clay County, North Carolina,
approximately 9 miles northeast of the town of Hayesville, NC. This action will restore natural drainage
patterns in the Little Buck Creek drainage; a state identified Outstanding Resource Water. The existing pond
was created by the previous land owners for private use. The earthen dam impounded approximately 0.6 acre
of Little Buck Creek in its headwaters.
Site B: An existing log check dam within Little Buck Creek has caused severe stream bank erosion and
channel widening. The log was installed at an elevation that is too high; therefore, it causes the stream
channel to be too wide and shallow. The site is located adjacent to a dispersed camp site and immediately
downstream of Forest Service Road 71.
Site C: A section of Forest Service Road 350A is located in close proximity to Buck Creek. Due to steep
terrain adjacent to the road, the road cannot be relocated away from the stream. Stream bank erosion is
occurring at this site and is threatening the existing road which also serves as the primary access for private
landowners downstream of the location.
3b. List the total estimated acreage of all existing wetlands on the property:
—0.4 acre of wetlands.
3c. List the total estimated linear feet of all existing streams (intermittent and perennial) on the property:
Site A —500 feet in the Little Buck Creek drainage.
Site B —50 feet in the Little Buck Creek drainage
Site C —50 feet in Buck Creek
3d. Explain the purpose of the proposed project:
Site A: The Forest Service is proposing to remove the earthen
dam structure and restore natural drainage patterns and
eliminate a high hazard dam. Recent inspections show
indications of structural and seepage problems with the dam
(see photos). This project is located just upstream from two
road crossings which may be affected in the event of a dam
failure. Approximately 500 feet of stream restoration would be
required from the dam to the inlet of the existing reservoir.
Additionally, restoration of the stream channel at the pond site
would reconnect approximately 0.2 mile of streams by
eliminating an aquatic organism passage barrier.
Site B: Removal of the log check dam in Little Buck Creek and
reconstruction of the stream bank would stabilize the stream
channel and restore it to a natural condition.
Site C: Installation of a boulder vane structure in lower Buck Creek
would direct stream flow away from the eroding stream bank
adjacent to the Forest Service Road and prevent further erosion.
This project would improve water temperatures within the Buck
Creek watershed and provide improved habitat conditions for the
native aquatic species within the watershed by restoring the stream
water temperatures and aquatic passage, and increasing stream
habitat complexity.
Page 4 of 14
3e. Describe the overall project in detail, including the type of equipment to be used:
SITE A:
Temporary gravity pumps will be utilized in conjunction with supplemental pumping systems to drain the
pond. Heavy equipment, such as trackhoes will be utilized to excavate the earthen berm. The existing
discharge flume, culverts, and related hardware will be removed. As needed, heavy equipment will be utilized
to restore natural contours (dimension, pattern and profile) of the Little Buck Creek stream channel affected
by the pond. Waste material will be removed from the site and native vegetation will be reestablished. Best
management practices to prevent nonpoint- source water pollution will be utilized to protect water quality
throughout the duration of the project. Approximately 500 feet of stream restoration would be required from
the dam site to the inlet of the existing pond to remove sediments and reestablish a stream environment.
Natural channel design concepts would be implemented to design channel dimension, pattern and profile
using reference reach data from the up and down stream reach.
The following stream work is proposed:
1. The earthen dam fill material would be removed (estimated 1,533 cubic yards of material) and
deposited and stabilized (graded, seeded and mulched) on adjacent areas including old roads.
2. Reservoir sediment deposits that restrict construction of the designed channel would be removed to
adjacent areas and stabilized (estimated depth of 1 foot of material).
3. Construct a channel with dimension, pattern, and profile to fit the site as defined by existing bedrock
and boulders, and the reference reach located up and down stream.
4. Incorporated into the channel design would be structures that mimic the natural involvement of trees
and boulders into the aquatic system. These structures could include J -hook vanes, vanes, root wads,
toe -wood, and woody debris placement that would promote wetland habitat.
5. Constructed stream banks would be covered with native seed and Coir matting, and planted with live
stakes and potted plants. The remaining disturbed soil would be seeded and mulched and planted with
potted plants.
Site B:
One existing log check dam within Little Buck Creek would be removed to restore the natural
width/depth ratio and to protect the stream banks. A new stream bank would be constructed and
revegetated.
Site C:
One boulder vane would be installed within Buck Creek adjacent to FS Road 350A using a trackhoe.
This structure will be placed at an elevation that will direct water away from the eroding stream bank
and also create a downstream scour pool.

D. Impact Justification and Mitigation
1. Avoidance and Minimization
1 a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing project.
Construction at the existing pond site would occur largely in the absence of streamflow since streamflow would be
pumped around the excavation work. Still, temporarily increases in turbidity are likely from the work, especially when
streamflow is first released to the new channel, but because of erosion control features (transplants, coir matting, etc.) the
amount would be minimal. Potential adverse impacts would be avoided by minimizing excessive excavation and adhering
to the State turbidity standard. Stream work is expected to be completed over a three week period.
b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques.
A. Minimize the area and degree of soil disturbance that reduces infiltration capacity and permeability, and destroys protective
forest floor and ground cover.
B. All hazardous materials will be stored outside of flood -prone areas and surrounded with sediment fence to reduce the risk of
materials reaching the river.
C. Work activities would not be scheduled on rainy days.
D. Heavy Equipment Operation.
1. All equipment shall be cleaned before entering the project area and stream, so as to reduce the risk of fine grained
sediment and oils and grease from entering the stream. This would also reduce the risk of invasive weed spread
onto the Forest.
2. Do not operate on wet soils when they are most susceptible to damage and erosion.
3. Operate heavy equipment on slopes less than 12 percent so as to reduce the risk of soil erosion. Avoid operating
heavy equipment on over- hanging stream banks.
4. Move large woody debris in a manner that minimizes disturbance of the forest floor, exposure of mineral soil, or
degradation of stream bank stability.
E. Install sediment fence to trap potential sediment. Stabilize any disturbed area at the end of each workday.
F. Re- vegetate exposed soils as soon as possible to take advantage of the loose soil conditions for seeding.
1. Exposed soil will be covered with straw mulch or erosion control matting at the end of the project. Matting will be
secured in place with stakes and live stakes where conditions allow.
2. Temporary seeding will occur on all bare soil within five days of ground disturbing activities to provide long -term
erosion control.
3. Stabilize channel banks with a native seed mix as work is completed.
G. Do not move sediment trap devices until the vegetation in the disturbed areas has been established.
H. During on -going operations inspect the site frequently; inspect occasionally during inactive periods.
1. Check for potentially damaging or failing situations that may cause unacceptable water quality impacts.
2. Correct failing situations as soon as practical.
I. Conduct visual inspections of streams while the work is being conducted to maintain acceptable turbidity levels.
Use a skilled heavy equipment operator, trained in stream restoration and construction of in- stream structures. Instruct the
operator to minimize disturbance to the streambed.
2. Compensatory Mitigation for Impacts to Waters of the U.S. or Waters of the State

Little Buck Creek Dam Decommissioning
and Stream Improvements Project
Background
The project consists of three
separate sites (Figure 1) located on
National Forest System lands,
Tusquitee Ranger District, in Clay
County, North Carolina,
approximately 9 miles northeast of
the town of Hayesville, NC.
The goals and objectives of this
project are to improve the health of
the stream ecosystem by improving
channel stability and habitat
quality, along with improving
riparian and streamside vegetation
conditions. The desired condition
is to have high quality riparian
areas and aquatic habitat features
that maintain hydrologic function,
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 designated uses.
Site A: This action will restore
natural drainage patterns in the
Little Buck Creek drainage; a state
identified Outstanding Resource
Water. The existing pond was
created by the previous land
owners for private use. The earthen
dam impounded approximately 0.6
acre of Little Buck Creek in its
headwaters (Figure 2).

Little Buck Creek Dam Decommissioning and Stream Improvements Project 2015
Figure Z Photo of existing dam of Little Buck Creep
Site B: An existing log check dam within Little Buck Creek has caused severe stream bank
erosion and channel widening. The log was installed at an elevation that is too high; therefore, it
causes the stream channel to be too wide and shallow. The site is located adjacent to a dispersed
camp site and immediately downstream of Forest Service Road 71.
Site C: A section of Forest Service Road 350A is located in close proximity to Buck Creek. Due
to steep terrain adjacent to the road, the road cannot be relocated away from the stream. Stream
bank erosion is occurring at this site and is threatening the existing road which also serves as the
primary access for private landowners downstream of the location.
Proposed Action
Site A: The Forest Service is proposing to remove the earthen dam structure and restore natural
drainage patterns and eliminate a high hazard dam (Figures 3 & 4). Recent inspections show
indications of structural and seepage problems with the dam. This project is located just
upstream from two road crossings which may be affected in the event of a dam failure.
Approximately 500 feet of stream restoration would be required from the dam to the inlet of the
21Page
Little Buck Creek Dam Decommissioning and Stream Improvements Project 2015
existing reservoir. Additionally, restoration of the stream channel at the pond site would
reconnect approximately 0.2 mile of streams by eliminating an aquatic organism passage barrier.

3 1 P a g c
Little Buck Creek Dam Decommissioning and Stream Improvements Project 2015
Figure 4. Little Buck Creek dam, project Site A, proposed stream rehabilitation.
Temporary gravity pumps will be utilized in conjunction with supplemental pumping systems to
drain the pond. Heavy equipment, such as trackhoes and bulldozers will be utilized to excavate
the earthen berm. The existing discharge flume, culverts, and related hardware will be removed.
As needed, heavy equipment will be utilized to restore natural contours (dimension, pattern and
profile) of the Little Buck Creek stream channel affected by the pond. Waste material will be
removed from the site, deposited in the nearby road cut and forest area (Figure 3) and native
vegetation will be reestablished. Best management practices to prevent nonpoint- source water
pollution will be utilized to protect water quality throughout the duration of the project.
Approximately 500 feet of stream restoration would be required from the dam site to the inlet of
the existing pond to remove sediments and reestablish a stream environment (Figure 4). Natural
channel design concepts would be implemented to design channel dimension, pattern and profile
using reference reach data from the up and down stream reach.
The following stream work is proposed:
1. The earthen dam fill material would be removed (estimated 1,533 cubic yards of
material) and deposited and stabilized (graded, seeded and mulched) on adjacent areas
including old roads.
4 1 P a g e
Little Buck Creek Dam Decommissioning and Stream Improvements Project 2015
2. Reservoir sediment deposits that restrict construction of the designed channel would be
removed to adjacent areas and stabilized (estimated depth of 1 foot of material).
3. Construct a channel with dimension, pattern, and profile to fit the site as defined by
existing bedrock and boulders, and the reference reach located up and down stream.
4. Incorporated into the channel design would be structures that mimic the natural
involvement of trees and boulders into the aquatic system. These structures could include
J -hook vanes, vanes, root wads, and toe -wood.
5. Constructed stream banks would be covered with native seed and Coir matting, and
planted with live stakes and potted plants. The remaining disturbed soil would be seeded
and mulched and planted with potted plants.
Site B: One existing log check dam within Little Buck Creek would be removed to restore the
natural width/depth ratio and to protect the stream banks. A new stream bank would be
constructed and revegetated.
Site C: One boulder vane would be installed within Buck Creek adjacent to FS Road 350A using
a trackhoe. Installation a boulder vane structure in lower Buck Creek would direct stream flow
away from the eroding stream bank adjacent to the Forest Service Road and prevent further
erosion. This project would improve water temperatures within the Buck Creek watershed and
provide improved habitat conditions for the native aquatic species within the watershed by
restoring the stream water temperatures and aquatic passage, and increasing stream habitat
complexity.

Log Vanes
Description
These structure serves to decrease stress in the near -bank region while promoting scouring in the
downstream pool. Logs are placed at an angle to the stream bank, gradually inclining in elevation until
they are located near % bankfull elevation directly adjacent to the stream bank. Water flowing
downstream is forced over these logs towards the middle of the channel, effectively scouring out a pool
below. The quantity of log vanes may be increased, decreased, or eliminated entirely at the direction of
the designer. Such variations in quantity will not be considered as alterations in the details of
construction or a change in the character of the work. The beaver dam simulation -cross vane is designed
to back up water to create a wetland feature.
Materials
Trees to be used for the vane shall be provided by the Forest Service from near the site. All log materials
shall be at least 10 inches in diameter. A sheet of non woven geotextile fabric (4oz, or greater) shall be
placed the length of the vane arm on the upstream side, stapled to the top log in a manner that they will
be covered by back fill material. Back fill material shall be obtained from the stream channel bed.
Installation
A trench shall be dug in such a manner that the footer and header logs are buried beneath the bed
surface elevation at least three feet. An excavator, with a bucket that includes a hydraulic thumb, shall
be used to place logs under the supervision of Designer. Logs shall be tightly sealed with no gaps
between the header and footer log. Filter fabric shall be placed on the upstream side of the structure
and backfilled with materials excavated on -site to prevent the washout of sediment through log gaps.
Filter fabric shall extend from the bottom of footer log to the finished grade elevation and shall be
placed the entire length of the structure. Header and footer logs shall be tied in securely to the bank in
81Page

Cross Valley Debris - Beaver Dam Simulator
Description
This feature is constructed to mimic a beaver dam to maintain existing reservoir- wetland characteristics when a
dam is removed.
Materials
Trees and brush to be used for the structure shall be provided by the Forest Service from near the site. Shrubs and
willow shall be provided by the Forest Service from near the site. Seed, mulch, coir matting, and riparian
plantings (live stakes, potted material, etc.) shall be provided and installed by the contractor.
Installation
The basic concept is to place logs perpendicular to the valley bottom slightly arched upstream in the center. Logs
should be placed so they touch the ground as much as possible and smaller logs, branches and woody debris
placed on the upstream side, and Coir matting placed over that. Coir matting shall be staked into the ground to
hold it in place and additional small woody debris placed over it. Where the ground is too wet to allow heavy
equipment logs can be pushed into the area from the drier side slopes using equipment and smaller woody
material can be brought in by hand. On average the surface should be flat across the valley however the pour -
point(s) should be located to conned to the downstream channel as much as possible. Downstream grade control
might be needed to ensure channel stability. Therefore, consider adding structures such as log- vanes, woody
riffles, and boulder placement downstream of this feature.

Toe - wood /Sod mat (bankfull bench)
Description
This structure serves to protect a length of stream bank by biulding a new bank with a bankfull area where one did
not exist before due to unstable conditions (See Toe - wood /Sod mat detail below). The structure creates a large
undercut bank providing an abundance of aquatic cover type habitat.
Materials
Trees and brush to be used for the structure shall be provided by the Forest Service from near the site. Shrubs and
willow shall be provided by the Forest Service from near the site. Excavated soil shall be hauled off the site and
dumped within 5 miles by the contractor. Seed, mulch, coir matting, and riparian plantings (live stakes,
potted material, etc.) shall be provided and installed by the contractor.
Installation
The channel shall be excavated to build a bench on the channel bottom on the outside of the meander
bend. Its elevation shall be well below determined low water elevation. A deep pool shall be
constructed where the new thalweg will be located, and excavated material shall be used to build the
point bar and back fill the structure. Footer logs laying parrallel to the stream channel shall be placed on
the bench, then the toe -wood on top of that. Toe -wood shall consist of a mixture of sizes, but include
several large tree stems with root wads attached. Stems shall be pushed into the bank were possible.
Trees, brush, and limbs shall all be used to fill this area with woody debris, and be placed up to the low
flow elevation. Bundles of live stakes, e.g. willow, shall be placed on top of the woody debris and alluvial
backfill shall be placed on the structure (amount determined by Designer). Shrubs, excavated from
nearby, shall be placed on top of the toe -wood up to the bankfull elevation. This shrub mat will replace
the "sod mat". From the bankfull elevation the verticle slope shall be excavated to the 2:1 slope (run to
rise). Excavated soil material shall be scattered on the adjacent terrace. All slopes shall have seed,
mulch, and coir matting installed. Riparian plantings shall be installed on the slope and during the plant
dormant season, live stakes shall be installed in the bench and bank.

Decision Memo
Buck Creek Watershed Improvement Project
Tusquitee Ranger District, Nantahala National Forest
Clay County, North Carolina
For Additional Information Contact:
Tusquitee Ranger District
123 Woodland Drive
Murphy, North Carolina 28734
(828) 837 -5152
Decision
I have decided to implement a watershed improvement project within the upper Buck Creek
watershed on the Tusquitee Ranger District, Nantahala National Forest, Clay County, North
Carolina. My decision will decommission an earthen dam on Little Buck Creek, restore fish passage
at five road crossings, remove log -check dams which are causing stream bank erosion, and restore a
stream bank at an old ford that is diverting streamflow around a natural waterfall barrier (this barrier
is preventing invasion of brown trout into a Southern Appalachian brook trout population).
Additional watershed improvements would include vegetating disturbed stream banks, maintenance
of one - existing -k- dam, repairing-one road- glide; restoration-of- stream - channels- using-natural -charm -ei --- - - - - --
design techniques at the existing pond site and five fish passage improvement sites.
Restoration of stream channels will include excavation and reshaping of stream banks at specific
locations and installation of rock and/or log J -hook structures to stabilize stream banks. All
disturbed soils will be stabilized to prevent erosion. This analysis includes effects determinations
for Sites 3, 4, 7, 8, 10, 11, 13, 15, 16, 18, 19, 20, 22, and 23 (see the Appendix to this DM). All
other sites identified on the map will be analyzed in a later document.
Reasons for Categorical Exclusion of Project
Decisions may be categorically excluded from documentation in an Environmental Impact
Statement or Environmental Assessment when they are within one of the categories identified in
the Code of Federal Regulations 36 CFR 220, and when there are no extraordinary circumstances
related to the proposed action. This project is excluded under 36 CFR 220.6(e)(17) Restoring
wetlands, streams, riparian areas or other water bodies by removing, replacing, or modifying
water control structures such as, but not limited to, dams, levees, dikes, ditches, culverts, pipes,
drainage tiles, valves, gates, and fencing, to allow waters to flow into natural channels and
floodplains and restore natural flow regimes to the extent practicable where valid existing rights
or special use authorizations are not unilaterally altered or canceled, 36 CFR 220.6 (e)(19):
"Removing and /or relocating debris and sediment following disturbance events (such as floods,
hurricanes, tornados, mechanical/engineering failures, etc.) to restore uplands, wetlands, or
riparian systems to pre - disturbance conditions, to the extent practicable, such that site
conditions will not impede or negatively alter natural processes"; and 36 CFR 220.6 (e)(20):
"Activities that restore, rehabilitate, or stabilize lands occupied by roads and trails, excluding
National Forest System roads and National Forest System trails to a more natural condition that
may include removing, replacing, or modifying drainage structures and ditches, reestablishing
vegetation, reshaping natural contours and slopes, reestablishing drainage -ways, or other
activities that would restore site productivity and reduce environmental impacts. "
a. Federally listed endangered or threatened species, designated critical habitat,
species proposed for Federal listing or area proposed as critical habitat, and
regionally sensitive (S) species:
A biological evaluation completed on February 3, 2015 determined that the project is not
likely to adversely affect the northern long -eared bat and Indiana bat. Concurrence with
these determinations of effect was made by the US Fish and Wildlife Service on March 2,
2015. There will be no impacts to any other proposed, endangered, or threatened species.
Implementation of the Buck Creek Watershed Improvement Project will have no impacts
(1) to any regionally sensitive aquatic species because none occur within the treatment
areas and because no off -site effects would occur to any aquatic resources; (2) to any
regionally sensitive botanical species because none occur in the project area; and (3) to
any regionally sensitive terrestrial wildlife species because none occur in the project area.
b. Floodplains, wetlands, or municipal watersheds:
Some project activities will occur in the floodplain and in riparian areas that were
artificially converted to wetlands when the pond across Little Buck Creek was
established. Project activities in the floodplain are designed to restore natural conditions;
the Forest Service will obtain necessary and appropriate permits from the US Army
Corps of Engineers prior to conducting any activities in jurisdictional wetlands. No
project activities will occur in municipal watersheds.
c. Congressionally designated areas, such as wilderness, wilderness study areas, or
national recreation areas:
None are located in the areas where project activities will occur.
d. Inventoried roadless areas (IRAs):
None are located in the areas where project activities will occur.
e. Research natural areas (RNAs):
The project areas does not include any RNAs
f. American Indian and Alaska Native religious or cultural sites, archaeological sites,
or historic properties or areas:
An archeological review completed in February 2015 determined that the project is an
Exempt Undertaking.
Purpose and Need for the Action
The purpose and need for the proposed treatments include restoring streams and riparian areas by
removing, replacing, or modifying water control structures and restoring native brook trout to the
watershed. Engineering assessments have identified seepage at the base of the dam on Little
Buck Creek as well as other structural concerns with the dam. US Forest Service engineers have
recommended that this dam be removed to eliminate safety concerns related to dam failure,
particularly at downstream campsites.
Scoping and Public Involvement
Providing public notice and identifying issues important to the public - - the scoping process - -
was conducted in February 2015 through direct telephone and e-mail correspondence with
individuals, groups, and other state and federal agencies known to be experts in watershed
management practices in the Southern Appalachian ecoregion. This rapid and targeted scoping
was conducted due to (1) the safety issues with the dam presented in the purpose and need
section and (2) because these types of watershed projects are conducted relatively infrequently
by the Nantahala National Forest and some of the persons contacted for this project are not
normally consulted on terrestrial land management projects. No negative comments were
received.
Public Notification
This Decision Memo and accompanying vicinity and unit maps will be posted on the NFsNC
web page at www.fs.usda.gov.nfsnc. This Decision will also be reported in the NFsNC Schedule
of Proposed Actions (SOPA) distributed by the Forest Supervisor's Office, Asheville, NC.
Findings Required by Other Laws
Forest Plan Consistency — The actions in this decision are consistent with the Land and Resource
Management Plan for the Nantahala and Pisgah National Forests and all amendments to the
Endangered Species — Implementing the actions in this decision will not affect threatened or
endangered species, or result in loss of any other species' viability, or create significant trends
towards Federal listing of the species under the Endangered Species Act.
Cultural Resources — The actions in this decision will not adversely affect any sites listed, or
eligible for listing, in the National Register of Historic Places, nor will they cause the loss or
destruction of significant scientific, cultural or historic resources.
Notice, Comment, and Appeal Opportunities
This project is not subject to administrative review.

Re: Removal of Little Buck Creek Dam, Tusquitee Ranger District, Nantahala National Forest,
Clay County, ER 15 -0758
Dear Mr. Hicks:
Thank you for your letter of March 20, 2015, regarding the above - referenced undertaking. We have reviewed
The Documentation and Assessment of the Little Buck Creek Dam and offer the following comments.
We understand the US Forest Service would like to remove the earthen dam structure, referred to as Little
Buck Creek Dam, and restore the natural stream channel so brook trout can be introduced to the creek and its
tributaries. We concur with your findings that the Little Buck Creek Dam is not eligible for listing in the
National Register of Historic Places, as it lacks historical, architectural and cultural significance. Thus, the dam's
removal will not affect any historic properties which may be in the area.
The above comments are made pursuant to Section 106 of the National Historic Preservation Act and the
Advisory Council on Historic Preservation's Regulations for Compliance with Section 106 codified at 36 CFR
Part 800.
Thank you for your cooperation and consideration. If you have questions concerning the above comment,
contact Renee Gledhill- Earley, environmental review coordinator, at 919- 807 -6579 or
environmental .reviewO..ncdcr.eov. In all future communication concerning this project, please cite the above
referenced tracking number.
Sincerely,
