Re: Lake Adger Navigation Channel Maintenance Dredging
Response to USACE Comments and Provision of Additional Information
Action ID: SAW-2015-007888
Dear David:
On behalf of the North Carolina Wildlife Resources Commission (NCWRC), Anchor QEA of North
Carolina, PLLC, is pleased to provide this response to the U.S. Army Corps of Engineers' (USACE's)
comments and provide additional information for the Lake Adger navigation channel maintenance
dredging (Action ID: SAW-2015-007888). The comments and request for additional information'
were in response to the Application for Department of the Army Permit Form 4345 (dated June 12,
2020; received by USACE June 16, 2020); Anchor QEA received them via email on September 14,
2020.
Responses to Comments on Corps Comments and Request for Additional
Information - Lake Adger Dredging Project, September 14, 2020
1. Submit an Alternative Analysis
USACE Comment Received September 14, 2020:
Under the Section 404(b)(7), the alternative analysis requires the applicant to demonstrate
there are no practicable alternatives to the proposed discharge that would have a less adverse
effect on the aquatic environment. Noncompliance with this requirement is sufficient basis for
the Corps to deny the project permit. Also, the unavailability of practicable alternatives does
not necessarily result in issuance of a permit. Compensatory mitigation cannot be used to
satisfy the alternative analysis.
The applicant must demonstrate to the Corps that the proposed project is the least
environmental damaging practicable alternative (LEDPA) to achieve the project's purpose. The

404(b)(1) guidelines requires selecting the LEDPA, provided it does not result in greater adverse
environmental consequences. No discharge of dredge or fill material shall be permitted if there
is a practicable alternative to the proposed discharge which would have less adverse impacts on
the aquatic ecosystem, so long as the alternative does not have other significant adverse
environmental consequences.
Alternatives must be practicable, feasible, and accomplish the project's purpose and need. An
alternative is practicable if it is available and capable of being done taking into consideration
cost, existing technology, and logistics in light of overall project purpose.
Alternatives not involving discharges into special aquatic sites are presumed available and have
less adverse impact on aquatic ecosystem, unless clearly demonstrated otherwise. Special
aquatic sites are sanctuaries and refuges; wetlands; mud flats vegetated shallows; coral reefs;
and riffle and pool complexes.
The analysis must include the no action alternative, the proposed project, and a sufficient
number of alternatives to demonstrate the applicant has considered alternatives to the
proposed project which may impact more or less aquatic resources. The analysis should clearly
state each alternative and document the rational and findings of each alternative. Each
alternative should state the extent of impacts to aquatic resources, effects to federally protected
species and historic properties, estimated cost, and summarize the construction methodology
and logistics.
Based on the submitted information for the proposed project, the Lake Adger dredging project
is considered water dependent by the Corps. The activity does require access or proximity to or
sitting within special aquatic sites (wetlands) which are within the Corps' project Area.
Therefore, you will not need to look at off -site alternatives in your analysis.
Response on Behalf of NCWRC
An alternatives analysis has been provided in Attachment A.
2. Final Design and Plans
USACE Comment Received September 14, 2020:
Provide final design and plans for the dredging and spoils disposal activities. The plans need to
include a vegetation monitor plan for the new or enhanced wetlands of the spoils disposal
areas. The plans should include the estimate volume of dredged material for the initial
dredging episode and the expected volumes for future maintenance dredging episodes.

January 15, 2021
Page 3
Response on Behalf of NCWRC
The 90% Design Set is included as Attachment B. Final design, plans, and means -and -methods will
be developed following selection of the dredging contractor.
The 90% Design Set references the Wetland Monitoring Plan which is included as Attachment C. The
wetland monitoring plan is not included in the 90% Design Set as it is expected to be issued as a
separate contract from dredging activities.
The 90% Design Set includes the estimated volume of dredged material for the initial 6,800 cubic yards
dredging episode. The 90% Design Set does not include expected volumes of future maintenance
dredging episodes as this volume will be dependent on future accretion rate which has not been
estimated, however the 90% Design Set does include an estimate of placement area volumes.
3. Aquatic Resources
USACE Comment Received September 14, 2020:
Provide an evaluation and discussion of the existing conditions of the aquatic resources
proposed to be impacted and how these resources will change based on the proposed project.
Response on Behalf of NCWRC
The existing conditions that will be impacted temporarily or permanently by the proposed dredging
activities are open water and wetland areas. The existing and anticipated future conditions are summarized
in the below table. The initial dredging project will result in a net increase of up to 3.0 acres of wetland.

4. FEMA Floodplain
USACE Comment Received September 14, 2020:
The project is located within the FEMA designated 700-year floodplain. The project must
comply with applicable FEMA-approved state and local floodplain management requirements.
Provide a copy of the approved FEMA permit or other documentation that indicate the project
meets these requirements.
Response on Behalf of NCWRC
A Floodplain Development Permit, issued by the Floodplain Administration for Polk County (issued
December 15, 2020) is provided in Attachment D. The permit requires that a no -rise certification is
provided within 30-days of project completion.
5. Schedule
USACE Comment Received September 14, 2020:
Provide a schedule for the dredging and disposal area activities for the initial episode of
dredging and an estimate of how often future dredging activities will be conducted.
Response on Behalf of NCWRC
The 90% Design Set (Attachment B) includes a Sequence of Construction for the dredging
contractor. Dredging and wetland establishment for the initial dredging episode is anticipated to
follow the following approximate schedule:
• Weeks 1 and 2: Mobilization to Site, marking of delineated wetlands extents, preparation of
wetland placement areas, and preparation for turbidity monitoring
• Weeks 3 to 5: Dredging activities
• Weeks 6 and 7: Demobilization and complete wetland placement activities
• Week 7 for several months: Monitoring of wetland placement area settlement to determine
planting timing, per wetland monitoring plan
• Two weeks following adequate settlement: Wetland planting activities
• Up to 2 years: Implementation of wetland monitoring plan
The occurrence of future dredging activities will be dependent on rates of future accretion and needs
to maintain the navigation channel; however, an initial estimate is that maintenance dredging will be
required every 5 years.

The Division acknowledges that the applicant's intent is to enhance and/or create wetlands as a result of this project,
however the Division recommends that this should be monitored and that a detailed course of action should be
developed should the project inadvertently cause a loss of wetlands. We recommend that the monitoring plan include
a requirement for a new jurisdictional determination (in areas of dredge spoil fill) and that NCWAM evaluations be
conducted to ensure that the wetlands to be filled by dredge material do not lose jurisdiction or incur a degradation of
function. We recommend that any approvals include a condition that should either [result in] loss of jurisdiction or loss
of function, the Permittee would be required to provide a mitigation plan to compensate for the loss. The creation of
new wetland areas within the lake may be proposed as "permittee responsible mitigation" provided they satisfy
mitigation site criteria at the time of proposal.

It will be the goal of the dredging activities to minimize public exclusion from the navigation channel and to maintain access
to the public boat ramp. It is estimated that the navigation channel may be off limits to the public for up to 3-weeks,
although efforts will be made during this time to maintain some access to the Lake. Dependent on the selection of means -
and -methods by the contractor and pending approval by the project engineers and stakeholder discussions, dredging
activities may require the Lake to be drawn down, which may limit access from the navigation channel to the Lake.

ALTERNATIVES ANALYSIS
Lake Adger Navigation Channel Maintenance Dredging Project
Anchor QEA of North Carolina, PLLC
ANCHOR
,�
SIZ QEA ` L-4-1
December 18, 2020
This alternatives analysis was developed to support a permit application for the Lake Adger
Navigation Channel Maintenance Dredging Project (Lake Adger Project) compliant with permit
requirements under Section 404(b)(1) of the Clean Water Act. In its review of the North Carolina
Wildlife Resources Commission (NCWRC)'s permit application for the proposed Lake Adger Project,
the U.S. Army Corps of Engineers (USACE) requested' NCWRC analyze alternatives to the proposed
project to "demonstrate there are no practicable alternatives to the proposed discharge that would
have a less adverse effect on the aquatic environment" (i.e., "the proposed project is the least
environmental damaging practicable alternative [LEDPA] to achieve the project's purpose"). This
alternatives analysis for the Lake Adger Project includes a summary of information requested in
USACE's comment letter.
As stated by USACE in their September 14, 2020, comment letter, the Lake Adger Project is
"considered water dependent [and] require[s] access or proximity to or sitting within special aquatic
sites (wetlands) which are within the Corp's project Area. Therefore [this alternatives analysis does]
not need to look at off -site alternatives."
This analysis summarizes the proposed alternative and presents four additional alternatives that were
considered during development of the 30% Design Submittal, with rationale for why each of the
considered alternatives was not selected.
Summary of Proposed Alternative
Per the Application for Department of the Army Permit Form 4345 (dated June 12, 2020; received by
USACE June 16, 2020), the proposed alternative includes an initial dredging event to remove
6,800 cubic yards (cy) of soft sediment from the navigation channel, with placement of the soft
sediment within the Lake Adger footprint as beneficial use for habitat creation, including wetland
creation and enhancement, or creation of upland areas. The dredged material placement areas will
be bounded by an initial containment structure designed to hold the sediment in place. This initial
structure will be constructed of biodegradable and/or temporary containment materials (e.g., coir
fiber biologs, haybales, or an equally effective alternative). Secondary turbidity controls (e.g., silt
fences or silt curtains depending on water levels) will assist with sedimentation control. Following

ecological benefits. In addition to the planting, the site will be seeded with a wetland seed mix
containing a variety of obligate and facultative wetland species to provide additional species
diversity and ground cover. The proposed alternative will improve the long-term environment to the
aquatic ecosystem through the development of additional wetlands.
The following summary information was requested by USACE in their September 14, 2020, comment
letter to support evaluation of this alternative:
• Extent of Impacts to Aquatic Resources — 21.2 acres
• Effects to Federally Protected Species and Historic Properties — None
• Estimated Cost — $1,300,000 to $1,800,000
• Summary of Construction Methodologies and Logistics
— Sediment will be dredged using hydraulic dredging equipment
— Dredged material slurry will be pumped through pipeline and discharged within the
designated dredged material placement areas
— Dredged material placement areas will be constructed using a combination of coir logs,
haybales, or equally effective alternative as sediment containment with secondary
turbidity measures of silt fences, silt curtains, or similarly effective materials
— Native emergent wetland and upland species identified at the nearby reference
wetlands will be planted on the dredged material to stabilize the material and provide
ecological benefits
Other Alternatives Considered
The following alternatives were considered in addition to the proposed alternative:
• No action
• Deep -water placement within Lake Adger
• Placement in an upland confined placement area
• Alternative dredged material placement methodologies within the proposed dredged
placement areas
• Construction of Permanent Containment Structure Around the Proposed Dredged Placement
Areas
No Action
The navigation channel provides public boat access from the boat ramp at the western end of the
lake to the main lake and is adjacent to the Lake Adger marina. The accretion of sediments within the
navigation channel has resulted in difficult transit for waterway users attempting to safely access
Lake Adger. Channel deepening is required to facilitate a safe navigable access channel to Lake
Adger. NCWRC is responsible for maintaining adequate water depths for the public boat ramp and
marina under an agreement with Polk County.

December 18, 2020
Page 3
This alternative was not selected due the NCWRC agreement to maintain the navigation channel, and
the public support for doing so in a safe manner.
The following information was requested by USACE to support evaluation of this alternative:
• Extent of Impacts to Aquatic Resources — None
• Effects to Federally Protected Species and Historic Properties — None
• Estimated Cost — $0
• Summary of Construction Methodologies and Logistics — Not applicable
Deep -Water Placement Within Lake Adger
This alternative would consist of dredging approximately 6,800 cy of sediment from the navigation
channel, with dredged material placement in deep -water portions of Lake Adger. The redistribution
of sediment associated with this alternative would be expected to contribute to ongoing sediment
buildup behind the Turner Shoals hydroelectric dam and within the Lake Adger aquatic system, result
in ecological impacts, and reduce the effective storage capacity of the water -supply reservoir. It is
anticipated that deep -water placement of dredged material in Lake Adger would contribute to the
need for future Lake dredging activities that would be costly, result in future additional impacts to
aquatic resources, and require identification of an alternative placement area.
This alternative was not selected due to the potential for future dredging work being required from
deep -water portions of Lake Adger.
The following information was requested by USACE to support evaluation of this alternative:
• Extent of Impacts to Aquatic Resources — estimated 20 to 30 acres depending on the
distribution of placement
• Effects to Federally Protected Species and Historic Properties — None
• Estimated Cost — $1,000,000 (excluding potential future re -dredging work)
• Summary of Construction Methodologies and Logistics
— Sediment would be dredged using hydraulic or mechanical dredging equipment and
material would be placed into a dredged material scow
— Material would be placed using a long -reach excavator positioned onshore or on a
barge
Placement in an Upland Confined Placement Area
This alternative would consist of dredging approximately 6,800 cy of sediment from the navigation
channel, with dredged material placed in a confined placement area located immediately adjacent to
Lake Adger. The public parking area adjacent to the boat ramp is the most suitable location for this
alternative; however, this area cannot be practicably converted into an upland confined placement
area without compromising and limiting the functionality of the public parking lot. Additionally, this

December 18, 2020
Page 4
option would require dewatering operations resulting in additional cost and turbidity control
requirements
This alternative was not selected due to no appropriate placement area being identified immediately
adjacent to Lake Adger.
The following information was requested by USACE to support evaluation of this alternative:
• Extent of Impacts to Aquatic Resources — 5.5 acres (assuming no special aquatic sites, such
as wetlands, are impacted by the construction and operation of an upland confined
placement area)
• Effects to Federally Protected Species and Historic Properties — None (assuming no
federally protected species or historical properties would be impacted in the upland confined
placement area)
• Estimated Cost — $1,500,000 to $4,000,000
• Summary of Construction Methodologies and Logistics
— Sediment would be dredged using hydraulic or mechanical dredging equipment
• If hydraulic dredging equipment is used, dredged material would be transported
via pipeline and discharged within the upland confined placement area;
dewatering would be required (e.g., geotubes or filter presses) to handle the
quantity of water generated
• If mechanical dredging equipment is used, dredged material would likely be
transported in a scow; a long -reach excavator positioned in the uplands would be
used to offload dredged material into the confined placement area
Alternative Dredged Material Placement Methodologies within the Proposed Dredged
Placement Areas
This alternative would consist of dredging approximately 6,800 cy of sediment from the navigation
channel, with dredged material placement in the same proposed dredged material placement as in
the proposed alternative. The methodology for placement would differ from the proposed
alternative as dredged material would be placed using mechanical methods such as a long -reach
excavator operating from a barge or constructed work area or an amphibious excavator. This
equipment would have limited placement reach, result in impacts to the placement areas, and
require construction of a staging area within the existing wetlands. Additionally, the transfer of
dredged sediment to the placement construction equipment would result in increased risk of
turbidity impacts and transfer of the sediment in less confining equipment such as a scow rather
than within a hydraulic transfer hose.
This alternative was not selected because the equipment necessary to complete this work would be
more invasive and destructive of special aquatic areas (i.e., wetlands and mudflats) during
construction than the placement methodologies in the proposed alternative.

December 18, 2020
Page 5
The following information was requested by USACE to support evaluation of this alternative:
• Extent of Impacts to Aquatic Resources — 21.2 acres (same as proposed)
• Effects to Federally Protected Species and Historic Properties — None
• Estimated Cost — $1,300,000 to $3,000,000
• Summary of Construction Methodologies and Logistics
— Mechanical dredging with placement in a dredged material scow
— Dredged material offloading facility to move material from scows into dredged material
placement area.
— Dredged material placement area construction using biodegradable and/or temporary
containment materials (e.g., coir fiber biologs, haybales, or an equally effective
alternative)
— Material placement within the designated dredged material placement areas using a
long -reach excavator or an amphibious excavator
— Native emergent wetland and upland species identified at the nearby reference
wetlands will be planted on the dredged material to stabilize the material and provide
ecological benefits
Construction of Permanent Containment Structure Around the Proposed Dredged Placement
Areas
This alternative would consist of constructing the containment structure from inorganic or less
degradable materials, such as geotubes, rock, or wood cribs.
The use of inorganic materials found in geotubes or matting will likely result in damaged and
partially broken-down material entering the environment, as removing them from the containment
area following settlement will be extremely difficult. Additionally, placement and use of these
products within the placement area will require additional construction traffic within the placement
area that can lead to unnecessary ecological disturbances. Biodegradable geotubes are a relatively
new technology, but are less suitable for containing fine sediment, and the biodegradable materials
have a lower strength that may reduce containment success.
Less biodegradable, natural options such as rock or wood cribs would require the import of materials
from off site. The placement of these materials in a configuration to contain placed dredged material
would be difficult on the in situ soft sediments. Their additional weight (compared to biodegradable
alternatives such as coir tubes) would likely require additional material to build a foundation prior to
constructing the containment structure. The use of timber will be difficult to secure during flood
events, and likely require a secondary layer of geofabric to contain sediment.
This alternative was not selected because the equipment necessary to complete this work would be
more invasive and destructive of special aquatic areas (i.e., wetlands and mudflats) during

December 18, 2020
Page 6
construction, and the import of either biodegradable or non -biodegradable materials from off site
will introduce materials into the environment that will have an undetermined long-term effect.
The following information was requested by USACE to support evaluation of this alternative:
• Extent of Impacts to Aquatic Resources — approximately 25 acres (same as proposed, with
additional operational areas required and larger containment structure)
• Effects to Federally Protected Species and Historic Properties — None
• Estimated Cost — $1,300,000 to $3,000,000
• Summary of Construction Methodologies and Logistics
— Sediment will be dredged using hydraulic dredging equipment
— Dredged material slurry will be pumped through pipeline and discharged within the
designated dredged material placement areas
— Dredged material placement areas will be constructed using either inorganic or less
degradable materials as sediment containment with secondary turbidity measures of silt
fences, silt curtains, or similarly effective materials
Conclusion
Six alternatives were evaluated on the basis of cost, environmental impact, constructability and
implementability. Based on this evaluation the alternative proposed in the Application for
Department of the Army Permit Form 4345 would have a less adverse effect on the aquatic
environment while being implementable and constructible. The proposed project is the LEDPA to
achieve the project's purpose.

WETLAND MONITORING PLAN January 12, 2021
Lake Adger Navigation Channel Maintenance Dredging Project
Anchor QEA of North Carolina, PLLC, in Consultation with North Carolina Wildlife Resources
Commission
A plan for maintenance dredging of the public boat ramp and marina navigation channel has been
developed by engineering consultant Anchor QEA of North Carolina, PLLC in consultation with North
Carolina Wildlife Resources Commission (NCWRC). A component of this plan involves in -lake
placement of dredged material to create stable habitat features in proximity to existing wetlands and
transitional areas in the forebay of Lake Adger. The placement areas have been identified on sheet
C4 of the 90% Design Set submitted with the Response to USACE Comments and Provision of
Additional Information'.
Monitoring the stability of the placement areas and the success of planted vegetation will be
performed by NCWRC staff or a qualified contractor according to the following protocol:
1. Prior to any dredging or placement activity under this permit, NCWRC will send notification to
the North Carolina Division of Water Resources (DWR) Environmental Specialists and the
U.S. Army Corps of Engineers (USACE) representative with jurisdiction over this project. This
notification will describe the proposed dates of dredging and placement activity and include a
map identifying the locations and extents of the proposed maintenance dredge and material
placement for habitat creation.
2. The dredging contractor will perform a certified as -built survey of the extents and topography of
the completed placement area(s) at the end of the dredging and placement phase. The
contractor's surveyor will set and locate a benchmark at the high point of each placement area.
As -built surveys will be submitted to NCWRC for each dredging and placement operation for
inclusion in the monitoring reports.
3. Prior to planting, the elevation benchmarks will be monitored to assess settlement and
consolidation of the placed sediment over time. Monitoring of settlement on a weekly and/or
monthly basis will allow project engineers to estimate that adequate settlement has occurred
prior to planting.
4. Following adequate assessment, the planting contractor and project engineers will estimate
total areas and numbers of each planting type, and submit a plan to NCWRC prior to initiating
planting.

5. Following planting, the planting contractor will prepare a report for NCWRC listing the date,
species, and numbers of plantings at each placement area. Once this report has been received,
DWR and the USACE will be notified that planting operations have been completed.
6. Six months following completion of planting operations, NCWRC (or contractor) will perform an
assessment and report on the condition of the placement area(s) and any other related
temporary impacts that will have been replanted. Starting with the initial report, this information
will be compiled and forwarded to DWR and the USACE. A standard form will be developed to
include the following information for planted placement areas associated with each dredging
operation:
a. The dredging contractor's as -built survey map, estimates of pre -planting settlement, and
the planting contractor's record.
b. A visual and photo assessment of the planted areas. Photos may be taken from a boat as
viewed from different perspectives and/or from the air by an unmanned aerial system. If
significant issues of plant community failure are observed, then NCWRC will map and note
the problems in the report and will coordinate corrective actions, if needed.
c. The elevations and coordinates of benchmarks previously set on the placement areas will
be surveyed and recorded. The elevations and positions will be assessed relative to those
surveyed and recorded for the contractor as -built report to measure the extent of any
consolidation or movement of the placed material. Any apparent instabilities will be
documented.
7. During the monitoring period, any observed problems, instabilities or significant plant
mortalities will be noted and communicated to DWR and the USACE. NCWRC staff will begin an
evaluation of problems and develop a plan for remediation, if required.
8. Subsequent monitoring of planted areas will take place at 6-month intervals for a period of
3 years after the initial report for the specific activity. Photos, survey data, and observations will
be appended to the initial report. At the end of monitoring Year 2, NCWRC, DWR, and the
USACE may review conditions of the wetland plantings and decide if the monitoring interval can
be reduced to once per 12 months or if there is a need for additional monitoring.
9. Each new dredging episode will require monitoring reports for the resulting placement and
planting. Subsequent placement area(s) will be subject to the monitoring plan and time frame
described in the above steps.

Re: Lake Adger Navigation Channel Maintenance Dredging
Standard Department of Army Application Form 4345
To Whom It May Concern,
On behalf of the North Carolina Wildlife Resources Commission (NCWRC), Anchor QEA of North
Carolina, PLLC, is pleased to provide this Application to the U.S. Army Corps of Engineers (USACE) for
the Lake Adger navigation channel maintenance dredging. This letter provides additional information
to supplement the attached Application for Department of the Army Permit Form 4345 from October
2012 (the Application; Attachment A).
Background
Lake Adger is located in Polk County, North Carolina. The lake is on the Green River and impounded
by the Turner Shoals Dam. The lake is approximately438 acres. AVicinity Map and a Project Area
Map are included on sheets G1 and E1, respectively, in the provided 30% Design Submittal for Lake
Adger Navigation Channel Maintenance Dredging (30% Design Submittal; Attachment B).
NCWRC has estimated that an initial dredging event in 2020/2021 will remove 6,800 cubic yards (cy)
of soft sediment from the navigation channel. This includes 3,800 cy to maintain adequate water
depths in the navigation channel for recreational use and 3,000 cy to address sediment loss incurred
during the lower Big Hungry dam removal in 2014.
It is proposed to place the initial estimated 6,800 cy of soft sediment within the Lake Adger footprint
as beneficial use for habitat creation, including wetland creation and enhancement, or creation of
upland areas.
To facilitate future maintenance dredging activities, the 30% Design Submittal includes defined areas
referred to as cells (Al, A2, 131, and Cl) with a total estimated capacity for approximately 12,000 cy1
For the purposes of estimated volume of removed versus placed sediment during the 30% design stage, a one-to-one volume is
assumed (i.e., no bulking or compaction will occur during the dredging and placement process). It is also assumed that average
placement depth will be up to the full pool elevation of 911.61 feet.

of soft sediment placement. Future maintenance dredging within the navigation channel or sediment
discharge within the design cells may occur under this permit through a renewal/modification
process.
Additional Information to the Application
The following subsections address specific blocks of the Application (Attachment A).
Block 17. Directions to the Site
Attachment C includes directions to the Lake Adger boat ramp from Asheville, North Carolina.
Block 18. Nature of Activity
The NCWRC is proposing maintenance dredging within the Lake Adger navigation channel to
remove accumulated sediment. The navigation channel provides public boat access from the boat
ramp at the western end of the lake to the main lake and is adjacent to the Lake Adger marina.
During initial proposed dredging activities in 2020/2021 an estimated 6,800 cy of soft sediment will
be dredged from the navigation channel and placed for beneficial use within the Lake Adger
footprint for habitat creation, specifically wetland creation and enhancement, or creation of upland
areas.
The 30% Design Submittal depicts the Activity, including existing conditions, project areas, and
design details associated with the proposed maintenance dredging. After comments are received
from USACE, the 30% Design Submittal will be updated to a 60% Design Submittal, followed by the
100% Design Submittal for construction.
Anticipated disturbance for the Activity area will be approximately 22.3 acres, which includes the
following:
• Staging area: 0.5 acres
• Navigation channel dredging disturbance area: 4.5 acres
• Material placement disturbance area: 17.3 acres, including 3.9 acres of dredged material
placement areas, allowance for sedimentation control, and access
The following subsections summarize aspects of the activities.
Pre -Design Investigations
The following pre -design investigations have been completed to support development of the 30%
Design Submittal and will be further used for developing the 60% Design Submittal followed by the
100% Design Submittal for Construction.

Bathymetric and Topographic Surveys
Bathymetric and topographic surveys were completed of the Activity area, and of an area of naturally
occurring wetlands and uplands near the proposed Activity (the reference wetland) in September
and October 2018. The majority of the topographic survey was performed using an unmanned aerial
system to collect LiDAR (Light Detection and Ranging) and RGB (red, green, blue) imagerywhen the
lake's water level was drawn down 5 feet below normal. Traditional bathymetry surveying methods
were used in areas that could not be dewatered, including in the navigation channel.
The topographic contours developed by the survey (Attachment D) are included in the 30% Design
Submittal.
The survey determined that the top of the overflow at the Turner Shoals Dam is at elevation 911.61
feet North American Vertical Datum of 1988 (NAVD88), as surveyed by Hayes, James & Associates,
Inc, dated October 9, 2018 (Attachment Q. The elevation of 911.61 feet NAVD88 is considered the
full pond level.
Wetland Delineation
A delineation of jurisdictional wetlands was completed byClearWater Environmental Consultants, Inc.
(CEC) August 21 through 22, 2018, and revised for submission to USACE on January 11, 2019.
Wetland function was evaluated utilizing the North Carolina Wetland Assessment Method (NC WAM)
and data sheets, including the USACE Regional Supplement to the 1987 Manual (Eastern Piedmont
and Mountains) Data Form and the NC WAM Field Assessment Form.
The USACE issued a Notification of Jurisdictional Determination on February 11, 2019 (Attachment Q.
Reference Wetland and Upland Assessment
An assessment of naturally occurring wetlands and uplands (the reference wetland) near the
proposed Activity was completed by CEC August 21 through22, 2018. This reference wetland is
upstream (west) of the Activity area where the Green River enters Lake Adger, and it has developed
and regenerated since the creation of the lake in 1925. As presented in Attachment F, six locations
within the reference wetland (reference point [RP] 1 to RP6) were assessed using NC WAM
methodology to determine the level of function in this wetland area regarding habitat, water quality,
and hydrology.
The data obtained from the RPs along with the elevation data for these areas will be used to determine
vegetation reestablishment within material placement areas, as discussed in the following subsections.
Sediment Sampling Study
An assessment was performed within the dredging footprint by Anchor QEAon October 5, 2017, to
characterize the chemical nature of the sediments. Details are provided in Attachment G. The

June 12, 2020
Page 4
analytical results were compared to North Carolina Department of Environmental Quality, Inactive
Hazardous Sites Branch, preliminary soil remediation goals (PSRGs) for soil.
As discussed in Attachment G, the assessment determined that volatile organic compounds,
semivolatile organic compounds, chlorinated herbicides, pesticides, and polychlorinated biphenyls
were not detected at concentrations that exceed their laboratory reporting limit in the discrete or
composited sediment samples. Multiple metals were detected in the composited sediment samples,
but only one constituent (arsenic) exceeded its industrial/commercial PSRG but was less than the
estimated arithmetic mean for background concentrations for soil in the eastern United States.
Geotechnical Investigations
Anchor QEA assessed sediment depth and thickness and physical properties on October 5, 2017,
September 20, 2018, and October 18, 2018. The results of the geotechnical investigations have been
used in developing the 30% Design Submittal and will be used for the 60% Design Submittal.
Hydraulic Modelling
A two-dimensional hydraulic model (HEC-RAS 2D) has been created for the Activity area. The model
development started with the existing, publicly available USACE HEC-RAS model and was enhanced
using the bathymetric and topographic data collected. This enhanced model can be used to simulate
velocities and water surface elevations over a range of flow conditions in the Green River and
Lake Adger.
The developed hydraulic model will be used during the development of the 60% Design Submittal to
assess the impact on flow regimes of constructing the placement area.
Staging Area
The proposed staging area for the Activity will be placed on the southwestern extent of the existing
public parking lot, adjacent to the public access boat ramp. The contractor will access the lake from
the public access boat ramp or a floating dock. Following dredging activities, the parking lotwill be
restored to its current condition or developed for an alternative use, as approved by applicable
stakeholders.
Navigation Channel Dredging
The navigation channel dredging area is approximately 1,500 feet long, with a base width of 20 feet,
slope of 1 (vertical) to 3 (horizontal), and elevation of 6 feet below the full pool elevation of 911.61
feet. The navigation channel will be widened in strategic locations to improve navigation by
removing 3,000 cy of sediment related to the lower Big Hungry dam removal.
Hydraulic dredging techniques are proposed, which will facilitate pumping of the dredged material
over a distance of approximately 1,500 feet directly to the material placement area.

June 12, 2020
Page 5
During operation of the Turner Shoals Dam for power generation by Northbrook, the lake's surface
elevation can vary by 2 to 3 feet during a week. Additionally, the lake can be drawn down and held at
5 feet below the normal level. Northbrook will continue to be consulted during the design stages to
discuss managing the lake's surface elevation during dredging and construction of the placement
area.
Dredged Material Placement Area
Throughout the Activity, the dredged material will be placed within the Lake Adger footprint as
beneficial use for habitat creation, specifically wetland creation and enhancement, or creation of
upland areas. Placing the material using hydraulic dredging discharge will allow course placement
within approximate depth and finished level ranges so that the design will include areas of wetland
and upland, channels and inlets, and various elevations to enhance hydraulic connectivity to the lake
to ensure frequent and prolonged presence of water at or near the soil surface, intermittent flooding,
and diverse vegetation establishment.
The 30% Design Submittal defined four areas for dredged material placement (Al and A2, B1, and
Cl) with a total estimated capacity for approximately 12,000 cy2 of soft sediment placement, up to
full pool elevation.
During material placement, these cells will be bordered by up to three separate structures (as shown
in Sheet C5 of the 30% Design Set):
1. An initial structure designed to hold the sediment in place will be constructed of biodegradable
and/or temporary containment materials. Containment materials may include haybales stacked
up to two layers high with a base width of two haybales, coir fiber biologs, or an equally
effective alternative. Containment materials will be secured in place with biodegradable stakes,
or an equally effective alternative method.
2. A second structure constructed similarly to the firstwill create a secondary dewatering barrier to
reduce sediment in discharged water.
3. After the two initial structures a silt curtain will be placed downgradient to assistwith
sedimentation control.
Based on the 30% Design Submittal, it is anticipated that the initially dredged 6,800 cywill be placed
in cells Al and A2. These two cells will allow improved management of the dewatering process by
allowing the discharge to be alternated between the two cells. For construction of cells Al and A2, it
is estimated that 840 feet of initial containment structures will be required, followed by 700 feet of
secondary containment structures, and up to 900 feet of silt curtain.
z For the purposes of estimated volume of removed versus placed sediment during the 30% design stage, a one-to-one volume is
assumed (i.e., no bulking or compaction will occur during the dredging and placement process). It is also assumed that average
placement depth will be up to the full pool elevation of 911.61 feet.

June 12, 2020
Page 6
Following the initial dredging effort of 6,800 cy, additional capacity will remain in areas Al and A2,
131, and C1 for future maintenance dredging events. These areas will only be delineated with
containment structures when needed for dredged material placement.
Monitoring During Dredging and Placement Activities3
Turbidity will be monitored during the Activity using hand-held or automated turbidity meters to
record Nephelometric Turbidity Units (NTU). Background data will be collected at a station located
upstream of the dredging and dredge material placement area. A monitoring location will be
established 1,000 feet downstream of dredging and material placement operations. During the first
week of operations data will be collected daily at the upstream background location, and twice daily
at the downstream monitoring location. The turbidity criteria will be that turbidity measured
downstream of dredging operations at the monitoring location are less than 50 NTUs above turbidity
measured atthe upstream background location.
If turbidity downstream of dredging and dredge material placement operations is more than
100 NTUs above the upstream background location, it will trigger review/evaluation of the Activity,
and response actions. An evaluation will be conducted to assess the cause of the exceedance and the
need for operational changes or other response actions. The evaluation may result in one or more of
the following actions, to be determined in the field:
• Increase frequency of monitoring at both background and downstream locations to hourly
• Review work operations and best management practices
• Identify additional best management practices to employ (e.g., additional containment
around the placement area)
• Reduce dredging and/or dredge material placement rate(s)
If no issues or exceedances are observed during the firstweek, data collection at the downstream
monitoring location will be reduced to once daily.
Habitat Establishment
Establishing habitat including beneficial wetlands and upland, is a common approach in lakes, rivers,
and estuaries to stabilize shorelines, restore habitat, and beneficially use dredged materials. After the
dredged soft sediment is placed in the cells, habitat establishment will include native wetland and/or
upland vegetation species dependent on the final elevation of placed sediment. Placed sediment
depth and final elevation will vary based on placement of the hydraulic dredging discharge line,
variable rates of passive dewatering, and compaction and subsidence. Varied final elevations will
promote establishment of plant species that differ in their ability to withstand prolonged inundation
or dry periods. The material's final elevation will be determined with a finished level survey.
a Details of the monitoring plan proposed herein will be refined with inputfrom the regulatory agencies.

June 12, 2020
Page 7
Native emergent wetland and upland species identified at the nearby reference wetlands (Table 1)
will be planted on the dredged material to stabilize the material and provide ecological benefits. In
addition to the planting, the site will be seeded with a wetland seed mix containing a variety obligate
and facultative wetland (FACW) species (similar to the mix shown in Table 2) to provide additional
species diversity and ground cover. Non-native and invasive species will not be planted.
Planting will occur in the next suitable planting season following placement of the dredge material to
allow for passive dewatering and settlement. Plants will be 2-inch plugs and planted on two -foot
centers (i.e.: 10,890 plants per acre). During vegetation establishment, herbivory control measures
will be installed as required to reduce predation bywildlife and waterfowl. Herbivory control
measures are anticipated to include construction fencing attached to posts around the perimeter of
the planted area, and possible covering by grid of wire/string to which flagging tape is attached.
Signage and flagging may be added as appropriate to minimize public access until the plants have
established resiliency to foot traffic and seasonal variations (generallyfor one or two growing
seasons).
Emergentwetland vegetation has relatively lowtolerance for wave energy and currents because they
can break the plants and wash away finer material, making the substrate too coarse. Therefore, the
containment structures (such as hay bales or coir fiber biologs) will be left in place until they
biodegrade to allow establishment of vegetation.

Block 19. Proposed Project Purpose
Maintenance dredging of the navigation channel is required to maintain adequate water depths in
the navigation channel for recreational use and to remove 3,000 cy of sediment related to the lower
Big Hungry dam removal. Performing wetland and upland creation with dredged material will
enhance habitat within the lake footprint by extending existing wetland areas. Enhancing natural
functions can include helping to reduce frequency and intensity of floods, thereby protecting the
area against storm surges; providing critical habitat, breeding grounds, and food resources for
organisms; improving water quality, and offering commercial, recreational, and aesthetic benefits.
Dredging and construction activities are anticipated to begin fall/winter 2020 and to be completed
early 2021.
Block 20. Reasons for Discharge
Dredged material will be discharged to the area designated on the 30% Design Submittal. This in -
lake placement will occur because no viable option has been identified for ex situ transport to and

June 12, 2020

placement of dredged material. Hauling the material outside of the Activity area would require a
dewatering process, an estimated 480 to 680 truck movements4, with additional placement,
compaction, stabilization, and revegetation activities required in area of placement.
Dredged material placement within the lake's footprint provides the following benefits:
• Efficient relocation of dredged material with minimal double handling and in situ dewatering
rather than requiring a separate dewatering operation
• Creation of a natural habitat
• A long-term solution of possible future dredging needs through the use of cells for placement
Block 21. Types of Material Being Discharged and the Amount of Each Type in
Cubic Yards
During the initial proposed dredging activities in 2020/2021, approximately 6,800 cy of dredged
material generally comprised of 50% sand, 30 to 40% gravel, and 10 to 20% silt and clay will be
dredged from the navigation channel. Debris encountered during dredging will be disposed of
outside of the Activity area if inorganic (e.g., trash and treated timber) or placed in the placement
area if it is organic and natural (e.g., logs and tree branches).
Block 22. Surface Areas of Wetlands or Other Waters Filled
Approximately 3.0 acres of water within areas Al, A2, B1, and C1 may be filled with the dredged
material, with the initial dredging of 6,800 cy filling approximately 1.8 acres within areas Al and A2.
Based on the delineation of jurisdictional wetlands and pending completion of the 60% Design
Submittal, it is anticipated that 1.1 acres of wetland below the full pond level (911.61) will be filled
within areas Al and A25. Dredged material will be pumped to the placement area using hydraulic
dredging techniques. Management of the placed materials is described in Block 18 and the attached
30% Design Submittal.
Block 23. Description of Avoidance, Minimization, and Compensation
Avoidance and minimization of impacts to waters of the United States are described in Block 18.
Strategies include the use of silt curtains to contain impacts to the project area, and monitoring. The
contractor will be trained in a safety and environmental procedures, which includes strict
containment protocol to minimize the potential for surface water impacts.
Compensation for wetland impacts is not required as the Activity will result in a gain of wetlands and
habitat development. Per Block 22, approximately 1.1 acres of wetland will be filled, with an
4 Based on dump truck capacities of 10 to 14 cy and an assumed requirementto transport6,800 cy of material (dependent on
volume bulking and reduction during dredging and dewatering activities).
s No wetland within Areas B1 orC1 is anticipated to be filled.

June 12, 2020
Page 11
additional 3.0 acres of delineated wetlands will possibly be impacted by operational activities
required for access and placement of the hydraulic dredge discharge.
Block 24. Is Any Portion of the Work Already Complete?
During August 2019, approximately 600 cy of dredged material was removed using mechanical
dredging methods and transported outside of the Activity area to the Polk County landfill. This work
occurred under the oversight of the NCWRC, with approval from Polk County and the USACE.
Block 25. Names and Addresses of Adjoining Property Owners, Lessees, etc., Whose
Property Adjoins the Project Site.
Adjacent property owners have been added to the Adjoining Property Owners List (Attachment H).
Maps depicting the parcel boundaries and ownership are included with this submittal (Attachment 1).
Owner and additional stakeholders of Lake Adger include:
• Polk County: owner
• NCWRC: responsible for maintaining adequate water depths for the public boat ramp and
marina under an agreementwith Polk County, and holding a perpetual easement to the
public parking area and boat ramp
• Northbrook Energy (Northbrook): Turner Shoals Hydropower facility operator
• Lake Adger Property Owner's Association: responsible for routine maintenance of the public
parking area and boat ramp
Block 26. Information About Approvals or Denials by Other Agencies
No other certificates or approvals/denials from federal, state, or local agencies pertaining to the
activities described in the Application have been received at the time of writing. Anchor QEA
understands that USACE will initiate contact with the following regulatory agencies as a part of the
Department of the Army Permit process. NCWRC and Anchor QEA will respond and coordinate with

Dear Colonel Clark:
July 8, 2020
NOAA's National Marine Fisheries Service (NMFS) reviewed the project described in the public
notice listed below. Based on the information in the public notice, the proposed project would
NOT occur in the vicinity of essential fish habitat (EFH) designated by the South Atlantic
Fishery Management Council, Mid -Atlantic Fishery Management Council, or the NMFS.
Present staffing levels preclude further analysis of the proposed work and no further action is
planned. This position is neither supportive of nor in opposition to authorization of the proposed
work.

Subject Project: Lake Adger Channel Maintenance Dredging
Dear Mr. Brown,
On behalf of the NC Division of Water Resources, we respectfully request that you consider the
following comments within your review of the 404 Individual Permit request for the above referenced
property:
The application notes that a wetland monitoring plan will be developed with input from the
resource agencies. We request that a detailed and complete monitoring plan for wetland
impact areas be finalized prior to issuance of approvals.
2. The Division acknowledges that the applicant's intent is to enhance and/or create wetlands as a
result of this project, however the Division recommends that this should be monitored and that
a detailed course of action should be developed should the project inadvertently cause a loss of
wetlands. We recommend that the monitoring plan include a requirement for a new
jurisdictional determination (in areas of dredge spoil fill) and that NCWAM evaluations be
conducted to ensure that the wetlands to be filled by dredge material do not lose jurisdiction or
incur a degradation of function. We recommend that any approvals include a condition that
should either loss of jurisdiction or loss of function occur, the Permittee would be required to
provide a mitigation plan to compensate for the loss. The creation of new wetland areas within
the lake may be proposed as "permittee responsible mitigation" provided they satisfy mitigation
site criteria at the time of proposal.

3. The Division recommends that the applicant provide a detailed phasing and/or construction
sequencing plan proposed for this project. For instance, will dredging activities be confined
within certain portions of the lake until completion/before progressing to the next work area?
How does the construction sequencing tie into the containment system design and turbidity
monitoring proposals?
4. The Division recommends that a more detailed and robust turbidity monitoring plan is necessary
and will coordinate with the applicant during 401 application review.
The applicant mentions future routine dredging activities to be covered by this approval. The
Division recommends that prior to commencement of any future dredging or disposal activities
the areas to be used for disposal should be re-evaluated by the regulatory agencies and may
require updated jurisdictional determinations and/or NCWAM evaluations, and that updated
monitoring plans to be developed for each future area which is proposed to impact wetlands,

SUBJECT: Lake Adger Navigation Channel Maintenance Dredging
Lake Adger Wetlands, Polk County
SAW-2015-00788
Dear Mr. Brown:
Biologists with the North Carolina Wildlife Resources Commission (NCWRC) reviewed the
individual 404 permit application modification for the Lake Adger Navigation Channel
Maintenance Dredging project, which would temporarily impact 3 acres and permanently impact
1.1 acres of wetland, as well as temporarily impact up to 14 acres and permanently impact 3
acres of open water, in Lake Adger in Polk County. NCWRC is the applicant for the permit, and
staff are familiar with the site and have attended multiple site visits. 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 reproduction, and a moratorium is not needed.
The permit is associated with the dredging of a navigation channel from the boat dock to the
lake. 6,800 yd3 of sediment would be hydraulically dredged in 2020-2021 from the navigation
channel, 3,800 yd3 of which are required to make the channel navigable. An additional 3,000 yd3
of sediment will be dredged at the navigation channel location, and this additional amount is
meant to compensate for sediment lost to the Big Hungry River during the removal of the lower
Big Hungry River dam in 2015. The dredged sediment would be piped 1,500 ft to be placed in
shallow in -lake placement areas Al and A2. The sediment would be allowed to drain in place
and contoured to create new or enhance existing wetlands, as well as create upland habitat. The
areas would be planted with native herbaceous and woody vegetation, using an adjacent
wetland/upland complex as a reference for the plant list.

Total disturbance for the project would be 22.3 acres, including 4.5 acres for the navigation
channel and 3.9 acres for sediment placement. The individual permit describes four areas for
sediment placement (A1, A2, B1, and C1, totaling 3.9 acres) that would allow for sediment
placement for the 6,800 yd3 and for future dredging activities. 1.1 acres of this sediment
placement area is jurisdictional wetland.
The sediment placement areas would be surrounded by two rows of biodegradable and/or
temporary containment materials (e.g., hay bales) as well as a silt curtain beyond these rows;
these measures are meant to hold sediment in place (especially the first row of material) and
control turbidity.
Turbidity would be monitored upstream and downstream of the activities, with turbidity sampled
once each day at the upstream reference and twice each day downstream for the first week, with
the goal of not increasing turbidity by more than 50 NTU from the upstream location. If the
turbidity goal is met during the first week, monitoring frequency would be cut back to once per
day. The application states that a review and possible change in activity will be taken only if
turbidity is 100 NTU or more above the upstream reference. It is unknown if any action would
be taken if turbidity increases 50-100 NTU from the reference.
We offer the following comments and recommendations on this project:
• The turbidity monitoring and contingency plan should be revised with the input of NC
Division of Water Resources (NCDWR).
• The vegetation monitoring plan should be developed with the input of NCDWR, US Army
Corps of Engineers, and NCWRC.
• We recommend adding Needle Spikerush and Silky Willow to the wetland plant list and
Persimmon and Black Gum to the upland plant list.
• Herbivory control fencing should consist of fabric that will not trap animals. NCWRC
biologists can provide recommendations at to the type of fencing that is appropriate.
• Although the text notes that 3.9 acres of area will be used for sediment placement, Sheet C5
notes that 1.1 acres of wetland and 3.0 acres of open water will be impacted by fill, which
totals 4.1 acres. These differences should be rectified.
Thank you for the opportunity to review and comment on this project. Please contact me at
[phone] if you have any questions about these comments.

Subject: [Non-DoD Source] Lake Adger Dredging Project: Request for Water Quality Protections,
Better Public Access & More
Dear Reg. Specialist David Brown,
I am pleased to see that NC Wildlife Resources Commission (NCWRC) has submitted a permit application to dredge the
public access channel at Lake Adger as it is obligated to do under the lake management agreement, and to use the
dredge spoils to construct engineered wetlands on the existing sediment delta. I support this important project to
protect public access to Lake Adger, since the channel has become nearly impassible to boat traffic due to
sedimentation.
I have some suggestions to make this project as successful as possible and to protect water quality during and after the
project:
Stakeholder Consultation - I request that NCWRC convene a stakeholder group consisting of parties to the lake
management agreement (Polk County, Lake Adger Property Owners Association, Northbrook Energy), MountainTrue's
Green Riverkeeper, and other interested parties like members of the fishing and boating community to receive feedback
and input on the details of the project. These project details would include timing, potential impacts to access and
water quality, lake level fluctuations, and other concerns of public interest.
Sediment Management - I appreciate the detailed turbidity monitoring protocols and support all efforts to control
sediment impacts during and after the project. I suggest adding silt curtains around the dredging area, not just around
the wetland construction area.
Wetland Construction - I support the strongest and most protective methods to contain and dewater material used to
construct wetlands. While hay bales may be cost effective to contain spoil material to form engineered wetlands,
options like coir fiber biologs, geotubes, and others should be explored to ensure that the best available technology is
incorporated into the project. NCWRC should specifically consider how high water events may impact constructed
wetlands and how these impacts can be mitigated.
Wetland Planting - I request that Water Willow be removed from the wetland planting list. NCWRC is currently studying
whether Water Willow is appropriate for introduction to Lake Adger, as it does not currently grow there. Following the
precautionary principle, this plant should not be introduced as part of this project. Rather, NCWRC should continue its
study and consult stakeholders on the potential future introduction of Water Willow.
Habitat Considerations - Be mindful of aquatic and wetland wildlife habitat, especially fish spawning beds that can be
affected by fluctuations in lake levels.
Expanded Public Access and Educational Opportunities - NCWRC should consider opportunities to expand and improve
public access and education in the project area, such as boardwalks, docks, fishing piers, and educational signage
explaining the history of the lake and the ecological significance of the Green River and surrounding area.
Public Communication - NCWRC should clearly communicate project details and timelines with the public as plans are
finalized.

Thank you for your consideration of these comments, and for the US Army Corps of Engineers' oversight and guidance of
this important project to protect public access to Lake Adger.

Re: Public Comment Concerning Lake Adger Marina Dredging Project, ID # SAW-2015-00788
Dear Mr. Brown:
Thank you for the opportunity to comment on this important project that improves public
access to Lake Adger. I appreciate the effort to gather and consider comments of interested
parties, especially those that live on Lake Adger like I do. I agree with many of the comments
presented by MountainTrue and am including them below with my additional comments.
Stakeholder Consultation - NCWRC should convene a stakeholder group consisting of parties to
the lake management agreement (Polk County, Lake Adger Property Owners Association,
Northbrook Energy), MountainTrue's Green Riverkeeper, and other interested parties like
members of the fishing and boating community to receive project details and provide pertinent
feedback and input including project timing, potential impacts to water quality and lake habitat,
lake level fluctuations, and other concerns of public interest.
Sediment Management — I appreciate the detailed turbidity monitoring protocols and support
all efforts to control sediment impacts during and after the project. I suggest adding silt curtains
around the dredging area, not just around the wetland construction area and reducing the
impact trigger from 100 NTU's to 75 NTU's. Additionally, if the trigger is activated, project
specifications should clearly call for ceasing all operations until corrective actions are enacted
and the turbidity levels return to 50 NTU's or below. Corrective operations must be initiated
and not simply reviewed or monitored more frequently.
Wetland Construction - I support methods to contain and dewater material used to construct
wetlands that do not introduce living non-native material or non -biodegradable material.
While hay bales may be cost effective to contain spoil material to form engineered wetlands,
options like coir fiber biologs, geotubes, and others should be explored to ensure that the least
environmentally damaging technology is incorporated into the project. NCWRC should
specifically consider how high water events may impact constructed wetlands and how impacts
can be mitigated.

Wetland Planting - Water Willow must be removed from the wetland planting list. It is a
nuisance plant that cannot be planted in a way that prevents its migration. Only material
native to Lake Adger or the nearby area should be used in this project.
Habitat Considerations - Be mindful of aquatic and wetland wildlife habitat, especially fish
spawning beds that can be affected by fluctuations in lake levels and do not lower lake levels
when fish are spawning on their beds.
Expanded Public Access Opportunities - NCWRC should consider opportunities to expand and
improve public access and education in the project area, such as boardwalks, docks, fishing
piers, and educational signage explaining the history of the lake and the ecological significance
of the Green River and surrounding area.
Public Communication - NCWRC should clearly communicate project details and timelines with
the public, especially Lake Adger residents, as plans are finalized.
Again, thank you for the opportunity to comment on this important project.

Monika Mayr

RE: SAW-2015-00788 - Lake Adger Dredging Public Comment
Dear Mr. Brown,
We are pleased to see that NC Wildlife Resources Commission (NCWRC) has submitted a
permit application to dredge the public access channel at Lake Adger as it is obligated to do
under the lake management agreement and to use the dredge spoils to construct engineered
wetlands on the existing sediment delta that has formed over the years since the Green River
was dammed in 1925 creating the lake. We support this important project to protect public
access to Lake Adger since the channel has become nearly impassible to boat traffic due to
sedimentation. We have some suggestions to make this project as successful as possible and
to protect water quality during and after the project:
• Stakeholder Consultation - We request that NCWRC convene a stakeholder group
consisting of parties to the lake management agreement (Polk County, Lake Adger

interest.
• Sediment Management - We appreciate the detailed turbidity monitoring protocols and
support all efforts to control sediment impacts during and after the project. We suggest
adding silt curtains around the dredging area, not just around the wetland construction
area.
• Wetland Construction - We support the most protective and strongest methods to
contain and dewater material used to construct wetlands. While hay bales may be cost

Re: Corps Action ID Number: SAW-2015-00788
Dear Mr. Broom,
We understand the North Carolina Wildlife Resources Commission (NCWRC) is
seeking Department of the Army authorization for 7.5 acres of permanent impacts to
open waters (dredging and conversion to wetlands); 9.5 acres of temporary impacts to
open waters (access and erosion control); 1.1 acres of permanent impacts to wetlands
(fill); and 3.0 acres of temporary impacts to wetlands (access and erosion control),
associated with dredging of the recreational navigation channel between the Lake
Adger public boat access area and the lake's main channel adjacent to the Lake Adger
Main Marina in Mill Spring, Polk County, North Carolina.
The Lake Adger Property Owners Association, Inc. Board of Directors (LAPOABOD)
recommends that USACE issue an authorization for the proposed work pursuant
applicable procedures of Section 404 of the Clean Water Act. The LAPOABOD also
reserves the right to comment on more detailed design specifications pertinent to the
proposed dredging once they are developed by NCWRC or their contractor(s).
Specific to the information provided, the LAPOABOD does offer the following
comments:
1. Silt curtains should be installed around any area where active hydraulic dredging is
occurring to reduce the potential for downstream resuspension of sediment.
According to the plan, turbidity monitoring is only occurring twice daily and if an
exceedance above 100 NTUs occurs, the plan does not call for dredging to stop until
further control measures are put in place.
2. Downstream turbidity testing should continue at an interval of twice daily for the
entire length of the project; not just the first week as conditions can change due to
weather related events.

3. The NCWRC should detail the anticipated timeframe the Lake Adger Main Marina
and the recreational navigation channel may be off limits to the public.
4. We request that NCWRC consult with the LAPOABOD prior to the selection of the
final plantings contained on page 14 of the plan to make certain any native species
selected do not become invasive.

Dear Mr. Brown,
This is in response to the Public Comment requests being sought for SAW-2015-00788, concerning the
application for Lake Adger Dredging Plans as submitted by North Carolina Wildlife Resources
Commission (NCWRC). While we support the dredging of Lake Adger, these are our comments and
concerns regarding this plan:
1. Concerning Cells B1 and C1— Protection of Culvert Between These Cells
a. Placement and breakdown of these cell materials could over time clog or close off the
drainage culvert running under Silver Creek Road.
b. Clogging of this drainage culvert could directly create flooding of Polk County Tax
Parcels #1— P54-199, #2 — P54-356, #3 — P54-132, and #4 — P54-133 as identified on
impacted Parcels presentation enclosed.
c. Clogging of this drainage culvert could also result in flooding of Silver Creek Road at that
point during heavy rain events that happen often.
d. We request that this plan address this potential issue.
2. Concerning Cell Al — Approximate Area of Disturbance
a. According to Plan C5, it appears that the upstream flow from the Green River will be
negatively impeded from flowing into the Lake Adger.
b. Water must not be -impeded from entering Lake Adger during this project which would
negatively endanger wildlife and water quality.
3. Concerning Cell B1— Choking off Permanent Green River flow into Lake Adger
a. There would appear to be some danger that Cell B1 will eventually close off the branch
of flow nearest Silver Creek Road leaving only one feed into the lake.
b. Concerns this reduction of flow will result in less turnover replacement of water in the
lake resulting in stagnation, reduced lake levels, and degradation to the quality of the
water.
4. Redirecting All Sediment Away from the Marina
a. This plan appears to recommend redirecting all sediment to travel into the deeper
middle channel of the lake.
b. If allowed to occur, the sediment from upstream will then build up significantly in a new
place. NCWRC is not under contract to have to dredge that portion of the lake. This
would inevitably leave Polk County with the responsibility and expense of dredging.
c. We request that Polk County Commissioners and citizens be made aware of this future
impact before approval of application.

S. Wetland Plantings
a. We would request that Water Willow be removed from the wetland planting list.
b. Polk County Commissioners are waiting on recommendation from Lake Adger POA citizens - On
December 2, 2019, NCWRC requested Polk County Commissioners to allow planting of Water
Willow into Lake Adger as a Test Site. The Commissioners deferred until Lake Adger Property
Owners Board and its citizens can make a recommendation to the Commissioners. Due to
COVID-19; efforts to inform citizens, investigate further, and make such recommendation to
Commissioners has stalled.
c. Willow Weed should not be introduced as part of this project. It is not native to Lake Adger.
d. We request that this application not approve specific plant species. NCWRC should be required
to consult stakeholders on final plantings.
6. Materials Used for Sediment Containment - Project Plan Description Page 4
a. On March 18, 2018, an original dredging plan was presented to Polk County
Commissioners by NCWRC with approval by Polk County to proceed for permitting.
b. On April 1,2019, NCWRC again appeared before the Polk County Commissioners to
explain why the permitting submitted to the USACE one year earlier was not the correct
permitting and new permitting application would have to be made. SAW-2015-00788 is
the result.
c. We request the original materials approved by the Commissioners for sediment
containment be used as opposed to hay bales in the plan. Refer to Option 2 — in Water
Replacement - Berm Construction Alternatives — Pg. 10 of March 18, 2018, NCWRC
presentation enclosed. This would also somewhat address Concern #1 in this letter.
7. Public Meeting
a. We request that a public meeting be held before application approval.
b. Citizens were denied ability to ask questions of NCWRC following the March 18, 2019,
presentation to Polk County Commissioners.
c. Citizens were promised by then Commission Chair Melton an opportunity to question
NCWRC once a new plan application was submitted.
d. As USACE does not individually respond to concerns and comments sent to them as part
of public comment, citizens were not previously allowed to ask questions, and a promise
was made to the citizens that questions would be allowed once the plan was developed
for USACE application submission; we believe a public meeting would benefit this
project.

RE: Corps Action ID Number: SAW-2015-00788
Mr. Brown:
I am commenting on the proposed plan to dredge the Lake Adger Marina. I am a full time resident of
Lake Adger, owning lake front property since 2002. As a volunteer with Mountain True's Clean Water
Team for 10 years and a past chair of the Lake Adger Lake Advisory Committee, I am, and have been for
a long time, an advocate for clean water in Lake Adger. I agree with Mountain True's comments listed
below but would like to add a few personal comments.
Due to the fact that many Lake Adger residents did not directly receive notification of this plan nor the
public comment until it was brought to our attention weeks after the announcement, I would like to
stress the point that the Lake Adger residents should be kept informed of this plan, especially prior to
the start of actual work being performed. Communication with the Lake Adger POA is essential.
The section of the plan that I am most concerned with is the planting of Justicia Americana (water
willow). In my research I have learned that this is considered a nuisance plant in some lakes and it is not
native to Polk County. I do not want to see water willow, nor any other plantings that are not native to
Polk County, planted in the waters of Lake Adger.
Sediment Management, wetland construction methods, and habitat considerations are also of
importance as detailed by Mountain True.
I would like to add that I would hope that during this process, NCWRC would considered adding more
recreational access for the public in the project area such as boardwalks, fishing piers, etc.. This would
provide more citizen access and opportunities for educational programs for citizens to learn about the
importance of wetlands.
I think the plan developed by NCWRC for dredging is much needed and I hope all citizen comments will
be taken into consideration.
Below are the Mountain True comments in which I am in full agreement:
MountainTrue has advocated for and supports this important project to protect public access to Lake
Adger, since the public access channel has become nearly impassible to boat traffic due to the
accumulating sediment delta. However, we have some suggestions to make this project as successful as
possible and to ensure that water quality is protected during and after the project.
Stakeholder Consultation — We request that NCWRC convene a stakeholder group consisting of parties
to the lake management agreement (Polk County, Lake Adger Property Owners Association, Northbrook
Energy), MountainTrue's Green Riverkeeper, and other interested parties like members of the fishing and

boating community to receive feedback and input on the details of the project. These details would
include timing, potential impacts to access and water quality, lake level fluctuations, and other concerns
of public interest.
Sediment Management — We appreciate the detailed turbidity monitoring protocols and support all
efforts to control sediment impacts during and after the project. We suggest adding silt curtains around
the dredging area, not just around the wetland construction area.
Wetland Construction — We support the strongest and most protective methods to contain and dewater
material used to construct wetlands. While hay bales may be cost effective to contain spoil material to
form engineered wetlands, options like coir fiber biologs, geotubes, and others should be explored to
ensure that the best available technology is incorporated into the project. NCWRC should specifically
consider how high water events may impact constructed wetlands and how impacts can be mitigated.
Wetland Planting — We request that Water Willow be removed from the wetland planting list. NCWRC is
currently studying whether Water Willow is appropriate for introduction to Lake Adger, as it does not
currently grow there. Following the precautionary principle, this plant should not be introduced as part of
this project. Rather, NCWRC should continue its study and consult stakeholders on the potential future
introduction of Water Willow.
Habitat Considerations — Be mindful of aquatic and wetland wildlife habitat, especially fish spawning
beds that can be affected by fluctuations in lake levels.
Expanded Public Access Opportunities — NCWRC should consider opportunities to expand and improve
public access and education in the project area, such as boardwalks, docks, fishing piers, and educational
signage explaining the history of the lake and the ecological significance of the Green River and
surrounding area.
Public Communication — NCWRC should clearly communicate project details and timelines with the
public as plans are finalized.

Dear Reg. Specialist David Brown,
Hi! I use Lake Adger for relaxation and paddleboarding almost weekly.
Thank you to the NC Wildlife Resources Commission (NCWRC) for submitting a permit application to dredge the public
access channel at Lake Adger, even if is an obligation.
The lake channels toward the Green River are getting hard to navigate due to the sediment.

Green Riverkeeper, and other interested parties like members of the fishing and boating community to receive feedback
and input on the details of the project. These project details would include timing, potential impacts to access and
water quality, lake level fluctuations, and other concerns of public interest.
Sediment Management - I appreciate the detailed turbidity monitoring protocols and support all efforts to control
sediment impacts during and after the project. I suggest adding silt curtains around the dredging area, not just around
the wetland construction area.
Wetland Construction - I support the strongest and most protective methods to contain and dewater material used to
construct wetlands. While hay bales may be cost effective to contain spoil material to form engineered wetlands,
options like coir fiber biologs, geotubes, and others should be explored to ensure that the best available technology is
incorporated into the project. NCWRC should specifically consider how high water events may impact constructed
wetlands and how these impacts can be mitigated.
Wetland Planting - I request that Water Willow be removed from the wetland planting list. NCWRC is currently studying
whether Water Willow is appropriate for introduction to Lake Adger, as it does not currently grow there. Following the
precautionary principle, this plant should not be introduced as part of this project. Rather, NCWRC should continue its
study and consult stakeholders on the potential future introduction of Water Willow.
Habitat Considerations - Be mindful of aquatic and wetland wildlife habitat, especially fish spawning beds that can be
affected by fluctuations in lake levels.
Expanded Public Access and Educational Opportunities - NCWRC should consider opportunities to expand and improve
public access and education in the project area, such as boardwalks, docks, fishing piers, and educational signage
explaining the history of the lake and the ecological significance of the Green River and surrounding area.
Public Communication - NCWRC should clearly communicate project details and timelines with the public as plans are
finalized.

Thank you for your consideration of these comments, and for the US Army Corps of Engineers' oversight and guidance of
this important project to protect public access to Lake Adger.
Sincerely,

Lake Adger Navigation Channel Maintenance Dredging Project
Anchor QEA of North Carolina, PLLC, in Consultation with North Carolina Wildlife Resources
Commission, and North Carolina Department of Environmental Quality Division of Water
Resources
A plan for maintenance dredging of the public boat ramp and marina navigation channel has been
developed by engineering consultant Anchor QEA of North Carolina, PLLC in consultation with North
Carolina Wildlife Resources Commission (NCWRC), and North Carolina Department of Environmental
Quality (NCDEQ) Division of Water Resources (DWR). It is proposed to remove 6,800 cubic yards of
soft sediment from the navigation channel and place the soft sediment within the Lake Adger
footprint as beneficial use for habitat creation.
Turbidity will be monitored by the contractor during project dredging and sediment placement
activities. Turbidity will be monitored using hand-held or automated turbidity meters to record
Nephelometric Turbidity Units (NTU) at a fixed upstream location (near the sediment placement area
but upstream of the influence of project activities) and a fixed downstream location that allows for
some in -lake mixing; approximate monitoring locations are shown on sheet C5 of the 90% Design
Set (attached) submitted with the Response to USACE Comments and Provision of Additional
Information'.
During the first week of operations, data will be collected daily at the upstream background location,
and twice daily (once 2 to 3 hours after daily operations have started, and again during the last 1 to
2 hours of daily operations) at the downstream monitoring location. If turbidity levels of >50 NTU are
not measured at the downstream monitoring location during the first week, then monitoring will be
reduced to once daily, taken during the last 1 to 2 hours of in -lake work for the remainder of the
maintenance dredging project or until excessive turbidity is measured. Turbidity will be recorded and
a turbidity log of all turbidity measurements will be sent to NCWRC and NC Division of Water
Resources (NCWWR) at the end of each work week.
The North Carolina turbidity standard is 25 NTU; attempts to keep turbidity at or below this level will
be made. An operations protocol that describes corrective actions and reporting requirements for
various turbidity scenarios is outlined in Table 1. Corrective actions include adjustments to
operations and best management practices (BMPs), examples of which are as follows:
• Performing dredging operations within a turbidity curtain system
• Adjusting the rate of the work to reduce suspended sediment

Information. Lake Adger Navigation Channel Maintenance Dredging Project. January 15, 2021.

• Optimizing the number of dredge bites that will achieve target dredge depth to increase
sediment capture
• Controlling the rate of dredging, including the rate of raising and lowering of the mechanical
dredge through the water, particularly when the dredge is close to the bottom of the river
• Not performing excessive and rapid movement of the dredge, such as dragging the dredge
on the bottom or reopening the bucket after initial closure
• Conducting pre -dredging removal of debris that could interfere with dredging
• Removing debris from the riverbed in a slow and steady manner
• Minimizing over -penetration of the dredge bucket to prevent overfilling
• Completely closing (to the extent possible) the dredge bucket before it is lifted through the
water column
• Moving dredge continuously and in the most efficient path to the barge once the dredge
breaks the water surface
• Conducting vessel operations in a manner that minimizes potential resuspension due to
vessel propeller wash (propwash)
