Emergency Action Plan

Dear Mr. Whitaker:
The letter dated September 6, 2005, requested The Division of Water Quality's comments on the operation of the
penstock and 24-inch bottom drain at Lake Tahoma. The described operation of the penstock would be desired, draw off
of clear water at velocities that would not cause deposition of sediment and erosion/degradation down stream.
Operation of the 24—inch bottom drain poses potential substantial adverse water quality impacts. In the request
for comments, the volume or mass of silt/sediment was not estimated. Based on the age of Lake Tahoma, a substantial
layer of material would be expected. Opening the bottom drain would deposit a potentially devastating mass of sediment
downstream. Additionally, the valve on this 24-inch bottom drain has not been operated for a long period of time. Should
the drain be opened, would it close? If the bottom drain would not close, unknown volumes of silt/sediment would
continue to be deposited downstream with prolonged environmental damage. Water Quality violations associated with
operation of the 24-inch drain would subject the responsible party to assessment of penalties, which could be $25,000.00
per day for the, length of time the discharge of sediment continued.
(The operation of the bottom drain valve is prohibited for any reason other than prevention of imminent death or
catastrophic property damage as determine by Federal Emergency Management or State/Local Emergency
Management.) IS THE STATEMENT CORRECT?( Should this determination be make, and the valve not close after the
danger is abated the above stated will apply.)
Your inquiry is appreciated. If there additional information is required, please contact me

WATER QUALITY SECTION
ASHEIALLE REGIONAL OFFICE
BP Barber is in the process of updating the emergency action plan (EAP) for the Lake Tahoma
Dam. We feel that two items in this EAP need review and comment from the Department of
Environment and Natural Resources. The dam and power house are owned and operated by the
Buck Creek Corporation that was established when the project generated electricity.. The Buck
Creek Corporation has given up their FERC license to generate power and the jurisdiction of the
dam is now under the regulation of the State of North Carolina. The 48-inch penstock and head
works from the power generation were retained so that the lake could be lowered to facilitate
maintenance of the docks and boat houses, facilitate the removal of sediment in the upper reaches of
the lake, and to be able to lower the lake in anticipation of heavy rains and flood conditions. There
also is a 24-inch line and valve at the bottom of the dam which at one time was used to lower the
lake levels for maintenance of the lake structures and in anticipation of heavy rains and subsequent
floods.
The two items in the EAP that effect both the operation of the dam and the water quality of Buck
Creek are the operation of the penstock and opening the 24-inch line at the bottom of the dam. The
current EAP procedure is to open the penstock prior to a forecasted flood condition and lower the
lake as much as possible before the rains begin. This operation takes water from the surface of the
lake and does not introduce silt 'into Buck Creek. The limiting condition for this operation,
however, is the amount of trash that is caught on the steel rack ahead of the penstock. The Lake
operator can keep the penstock open so long as the trash rack can be kept clean without endangering
the safety of the operator. The trash rack is cleaned manually using a long rake. Large logs and
limbs are pulled away from the rack using a boat. Normally, prior to a flood, the water in the lake is
clear and the level can be lowered without capturing very much trash. If previous rains have
brought in limbs, leaves, and debris in the lake, the racks can become clogged and unsafe even

r .•
before the flood rains begin. Once the rack becomes too clogged to safely remove the trash and
debris, the lake operator closes off the flow to the penstock. Prior to a flood event the Lake can
usually be lowered a few feet if the flow rate into the lake is low and the lake water is clear. Once
the flood begins and trash and debris are washed into the lake, the lake operator cannot safely clean
the rack and the penstock is closed. The decision to close the penstock is to be made by the lake
operator based on the amount of trash that is accumulating on the rack and the ability of the
operator to safely remove it. This is important because if the rack cannot be kept clean, the
differential in water levels ahead of and behind the rack will increase very rapidly and collapse the
steel bars and frame into the sluice gate and into the mouth of the penstock. Based on the current
EAP, the 24-inch valve at the bottom of the dam is not opened either prior to, or during a flood
event.
As an update to the existing EAP, the procedure for operating the penstock during a forecasted
flood event should remain the same. The Board of Directors of Lake Tahoma, however, is
requesting that, in addition to opening the penstock, the Buck Creek Corporation be allowed to open
the 24-inch bottom drain at the dam. The Board wants Buck Creek Corporation to be able to open
the bottom drain at the same time that the penstock is opened to lower the water level in the lake
prior to a forecasted flood event or open the drain during a flood condition to reduce pressure on the
dam. Prior to the flood, opening the drain would lower the lake more rapidly than only using the
penstock., However, silt in the lake is over the inlet to the 24-inch line and opening the valve would
discharge silt into Buck Creek downstream of the dam. During a flood event, opening the 24-inch
line would reduce the height of the water over the spillway and reduce the pressure on the dam.
On behalf of The Buck Creek Corporation and at the request of the Lake Tahoma Board of
Directors we are requesting that you review the above emergency operation of the penstock and the
use of the 24-inch bottom drain and comment on the proposed operations so that the update to the
EAP can be completed. We are sending a copy of this letter to the Janet Boyer in the Asheville
Regional Office and to Roger Edwards for his review and comments on the impact on water quality.
The Buck Creek Corporation is ready to schedule a Table Top exercise with McDowell County to
simulate several emergency conditions and their response to those conditions as soon as the EAP
procedures on operation of the penstock and bottom drain are reviewed by NCDNER Division of
Surface Water Protection and your Division of Land Resources.
Please let us know if you have questions concerning this letter or if additional information is needed
for your review.

On October 30, 2002, the Federal Energy Regulatory Commission (FERC) surrendered
license number 4021 for the Lake Tahoma Hydroelectric project on Buck Creek in
McDowell County. This letter confirms that the dam and its appurtenances passed to the
jurisdiction of the North Carolina Dam Safety Program as provided by North Carolina
General Statues 143-215.23 et seQ. (the North Carolina Dam Safety Law of 1967), and
the North Carolina Administrative Code, Title 15A, Subchapter 2K (the Dam Safety
Rules).. These statutory and regulatory requirements provide for dam safety assurance
and minimum stream flow releases. We are requesting a minimum flow determination by
the Division of Water Resources of this Department.
We understand that the dam did not exhibit any visible conditions at its last inspection
that would affect its immediate safety. The Land Quality Section will make routine
visual safety inspections, typically once per year. The owner should continue to provide
the same level of inspection and maintenance as when the dam was under FERC
jurisdiction. To help assure the continued safe operation of the dam, we require the
following:
1. The Emergency Action Plan (EAP) shall continue to be maintained and updated at
least annually.
2. An Operation and Maintenance Plan (OMP) shall be developed for this dam. This
OMP shall address the passage of the minimum release (to be determined) and the
comments and recommendations made by the Wildlife Resources Commission on
August 26, 2002 (copy enclosed). The OMP will also include actions to prevent
sabotage and vandalism.

Dear Mr. Gotzmer:
Michael F. Easley, Governor
William G. Ross Jr., Secretary
We understand that the owner of Lake Tahoma Dam on Buck Creek in McDowell
County proposes to surrender the Federal Energy Regulatory Commission (FERC)
license. This letter will confirm that the structure will then be under the jurisdiction of
the North Carolina Dam Safety Program as provided by North Carolina General Statues
143-215.23 et seq. (the North Carolina Dam Safety Law of 1967), and the North Carolina
Administrative Code, Title 15A, Subchapter 2K (the Dam Safety Rules). These statutory
and regulatory requirements provide for dam safety and minimum stream flow releases.
We also understand that the dam did not exhibit any visible conditions at its last
inspection that should affect its immediate safety. We do request that all stipulations
associated with the application for surrender to be implemented prior to release by FERC.
After the dam is under state jurisdiction, we will continue to make routine visual safety
inspections, and require that maintenance, deficiencies, and minimum flow releases be
addressed by the owner of the dam. The owner should continue to provide the current
level of inspection and maintenance once the dam is under state jurisdiction, including
the following operational requirements:
1. The Emergency Action Plan shall continue to be maintained and updated at least
annually.
2. The owner shall retain the services of an engineer with experience with concrete
arch dams to annually inspect the dam and report any problems to the owner and
the Department of Environment and Natural Resources, Land Quality Section.
3. Bi-annual monitoring of the dam deflections and water temperatures shall

Lake Tahoma Silt Removal Project
McDowell County
Dear Mr. Huff:
I am writing in response to your request to proceed with Lake Tahoma water level lowering and silt
removal project.
I have not received a response to my January 6, 1999 letter to Mr. Steve Chapin in which I recommended
that the Corps of Engineers permit he modified to incorporate specific environmental actions. In discussion with
Mr. Chapin, however, he suggested that we present our concerns to you and reach an acceptable agreement.
I also received a call from Dr. William Griffin on February 12, 1999 indicating that the Lake Tahoma
Association does not intend to proceed with the project this winter because of concerns about interfering with
the Marion water plant and because there is not enough time to complete the lake refill by March 1st, as required.
As previously stated, our primary concern relates to complications which could develop or worsen due
to drought conditions. In that regard, it is still our recommendation that the project be rescheduled for next
winter. While we have recently received normal rainfall, long range weather predictions still call for warmer -
than -normal weather. Groundwater tables, which keep stream flows replenished, are still below normal.
Before and/or during the project, there are certain environmental concerns which must be considered,
precautions which must be taken and measurements required or implied by the permit and state water regulations:
The most obvious precaution is that the work be closely coordinated with the Marion water
treatment plant in order for the project manager to advise Chief Operator, Buck Byrd, of any
condition that might result in water outage or water quality problems. Conversely, Buck needs
to be able to contact the project manager at all times in order to advise him when the!project
work is causing a problem at the water plant. If the project work impacts the stream in a way
that interferes with normal water plant operation, we ask for your commitment to take whatever
corrective action is needed to get the stream and water plant back to normal operating
conditions.
We do need your projected schedule for drawdown and refill. I know it may have to change
to suit stream conditions and work needs from day-to-day. Still, we would like to have a
clearer understanding of the time period involved so we can anticipate seasonal impacts. This
would also help the water plant operator to schedule operating times, source selection,
chemical feed adjustments, etc.
Buck Creek from source to Marion's water supply intake, including Lake Tahoma, is classified
WS-II Trout or WS-II&B Trout. North Carolina water quality rules require that the applicable
water quality standards (copy enclosed) not be contravened by project activity.

4. Project activities are not allowed to increase the turbidity by more than 10 TU in the stream
b or lake. Upstream and downstream turbidity measurements must be taken and submitted to
> determine and to document that this standard is met. On behalf of
the Wildlife Resources Commission, it should be noted that March is the most active spawning
period for Rainbow Trout. Trout are especially vulnerable to excessive suspended solids and
siltation during the spawning period.
Other needed water quality measurements in the water released from Lake Tahoma include
dissolved oxygen, iron, manganese, nitrate, color and pH. These parameters are needed as
indicators of water quality changes which could interfere with water treatment. As the project
progresses, parameters could be added or deleted if indicated.
6. A minimum release from Lake Tahoma of 11 CFS or the low flow of Buck Creek, whichever
is less, is required at all times. Upstream and downstream measurements must be made and
recorded to document adequate release.
These water quality and flow measurements should be made and recorded every four hours
while water lowering, silt removal or related project activities are in progress and at least daily
when project work is not active for the day (once the project begins). Water quality
measurements must be in accordance with the current edition of Standard Methods for
Examination of Water and Wastewater. Mr. Ray McCall, our Water Treatment Plant
Consultant, will work with you to set up an acceptable sampling plan and analysis procedure.
Please submit your responses to these items prior to beginning lake lowering or silt removal activities.
Thank you and the Lake Tahoma Association for your consideration. If you have questions or need our
assistance, please let us ]snow by writing or calling [phone].
Sincerely,
�HaroldSay

Re: Pefmit Number 199702Q95�
Like Tahoma Silt Remo al Project
McDowell County
Dear Mr. Chapin:
I met with representatives of the City of Marion, Lake Tahoma Corporation, Mr.
Peter Huff with Duke Engineering and Mr. Terry West with the Federal Energy Regulatory
Commission on January 5, -1999 to discuss the referenced project.
Water quality and quantity concerns were discussed in some detail. Everyone was
in agreement about the need for the project, and in fact everyone supported the project
concept. it was also apparent though that there were some potential water supply problems
that needed further evaluation and contingency planning.
The tentative agreement reached among the parties was that Lakejahoma,
Corporation would proceed with the valve replacement and trash rack cleaning components
of the project which could be accomplished without lowering the water level or disturbing
the sediment. However, the lake �ater level lowering and the silt removal components of
the project would not proceed at this time, pending drought relief and further evaluation
of the water supply quantity and quality impact.
In view of new information concerning drought conditions which could not have
been anticipated at the date of permit issuance in 1997, we recommend that the permit be
re-evaluated and modified.
Water supply concerns related to Marion's use of:B l Creek as a water supply
source while the project is in progress should be detailed, and plans to resolve the concerns
should be included as conditions of the permit. I suggested that an environmental
consultant be employed to evaluate the potential impacts and develop a plan to lessen'.or
mitigate them. The plan should be developed in close coordination with the City of Marion
and this office. '
The Lake Tahoma Corporation representatives were concerned about delays because
of funding and homeowner support. I think it is reasonable to anticipate proceeding with
the project within a year or less. Of course, this is dependent to a great extent on drought
persistence which none of us can predict.

Subject: Action No. 199702095, Lake Tahoma Sediment Basin and Excavation
The Division of Water Resources (DWR) has reviewed the public notice for a permit application to
construct a sediment control structure and basin in the backwaters of Lake Tahoma on Big Buck
Creek and to excavate accumulated sediment from the lake. DWR is concerned about the impact of
the proposed actions on public water supplies, aquatic habitat and recreation.
The Town of Marion relies on Buck Creek for a daily withdrawal of million gallons per day
(mgd) or 0.8 cubic feet per second (cfs). The Lake Tahoma dam has a minimum release requirement
of 11 cfs or inflow, whichever is less. If the proposed actions proceed, the permit holder should
contact the Town of Marion and the Division of Environmental Health Regional Office (Harold
Saylor, 704-251-6788) before commencing the drawdown. The elevation to which the reservoir will
be lowered, the len,th of the drawdown, and the refilling schedule should be understood_.by all parties
in advance so that the Town of Marion's water supply is not negatively impacted
Aquatic habitat in Big Buck Creek below the Lake Tahoma Dam depends upon an adequate flow of
water in the Creek. If the proposed actions proceed, the permit holder should maintain the minimum
flow requirement during all phases of reskrvoir level manipulations. A drawdown during winter will
allow easier refill.
Buck Creek, from Lake Tahoma to the Catawba River, is listed in Bob and David Benner's Carolina
White Water: A Paddler's Guide to the Western Carolina's as a reasonable float during high flows.
The minimum flow requirement should be maintained during the proposed actions to help maintain
sufficient flow of water for canoeing 'this section of Buck Creek.

RE: Permit Number 199702095
Lake Tahoma Silt Removal Project_
McDowell County r
The Public Water Supply Section of the Department of Environment and Natural
.osources is the state agency in North Carolina with the primary responsibility to ensure
iat all public water supplies provide safe and adequate potable water. In this role, we are -
mcerned about the referenced project.
On December 29, 1998 we received from the City of Marion, a . copy • of .an
spending action notice from the Lake Tahoma Corporation that the project would begin
.nuary 5, 1998. We had not had any contact concerning this project since September,
)96. At that time the project was only to draw down the lake 12 - 15 ft, repair a valve
4 clean out debris around the dam. It was expected to last about 2 weeks. After meeting
i site with the Lake Tahoma Corporation, City of Marion and McGill Engineering, I
ncurred with the project under a plan descrikel ed by the engineer. See the enclosed letters
Mr. Terry West of the Federal Energy Regulatory Commission. I note that your permit
indicated that I was to be contacted prior to drawdown.
We have several concerns about this project as related to tlie=use-of-.Buck--Creek-as
thnthc-City=of -Maion--at -ah- ntake--2--_- 3 niles
downsm-
We are currently in a severe drought situation, with record low flows in the
Catawba River basin. Any activity that could lessen the flow in Buck Creek is of great
concern. Our concern is heightened in this case, because Marion's back-up sources -in
Mackey Creek and Clear Creek are greatly diminished. Any unforseen incident causing
t9ow or water quality problems would leave Marion with no water supply options.

We are- also concerned with potential water quality degradation, Water released
from the bottom of the reservoir would be devoid of oxygen: and concentrated with iron,
�r maganese, phosphates, etc. From our experience, it is doubtful that Marion's. water -
treatment plant could remove these to drinking standards. • Dingy water usually results, ,,.
r causing disinfection problems and outcry from the public. Any water drained "should be
!�1 from the upper level of the lake.
With the reservoir lowered by 12 - 15 R, there will be large areas of lake bottom
exposed around the periphery of the lake. Heavy rainfall could wash large quantities of silt
and debris into the remaining water causing it to become very turbid and filled with tine
debris,This could be more than the filter plant can handle. Again, the fact that we are in
a severe drought condition leaves us without adequate source water options.
Our first recommendation Is that the draining and silt removal components of the
project be postponed until we recover from the current drought and have fi n flow in Clear
Creek and Mackey Creek.
If it is imperative that the draining and dredging proceed at this time, I recommend
a conference with all the parties involved to discuss the project In detail. In fact, 'l have
just received a call ftom Mr. Peter Huff with Duke Engineering suggesting a meeting on
January •5; •1999 at Mr. Tom Hollifield's house beside Lake Tahoma. • - I plan to be there and
hope .that someone from your office can also.
We would like for the Lake Tahoma Corporation to move forward with this project,
as it will improve Marion's water supply for the future. But, there could be serious short
term health impact if all necessary precautions are not taken.
Thank you for your consideration. Please call me at [phone] if we need to
discuss further.
Sincerely,
Harold Saylor

Re: Permit Number .199702095
Lake Tahoma Silt Removal Project
McDowell County
Dear Mr. Chapin:
I met with representatives of the City of Marion, Lake Tahoma Corporation, Mr.
Peter Huff with Duke Engineering and Mr. Terry West with the Federal Energy Regulatory
Commission on January 5, 1999 to discuss the referenced project.
Water quality and quantity concerns were discussed in some detail. 'Everyone was
in agreement about the need for the project, and in fact everyone supported the project
:oncept. It was also apparent though that there were some potential water supply problems
hat needed further evaluation and contingency planning.
The tentative agreement reached among the parties was that Lake Tahoma
:orporation would proceed with the valve replacement and trash rack cleaning components
)f the project which could be accomplished without lowering the water level or disturbing
he sediment. However, the lake water level lowering and the silt removal components of
he project would not proceed at this time, pending drought relief and further evaluation
if the water supply quantity and quality impact.
In view of new information concerning drought conditions which could not have
been anticipated at the date of permit issuance in 1997, we recommend that the permit be
re-evaluated and modified.
Water supply concerns related to Marion's' use of Buck Creek as a water supply
source while the project is in progress should be detailed, and plans to resolve the concerns
should be included as conditions of the permit. I suggested that an environmental
consultant be employed to evaluate the potential impacts and develop a plan to lessen or
mitigate them. The plan should be developed in close coordination with the City of Marion
and this office.
The Lake Tahoma Corporation representatives were concerned about delays because
of funding and homeowner support. I think it is reasonable to anticipate proceeding with
the project within a year or less. Of course, this is dependent to a great extent on drought
persistence which none of us can predict.

as stated in Sub -subpart (d)(3)(B)(i)(I) of this Rule, then engineered stormwater controls
must be used to control runoff from the first inch of rainfall; new residential and non-
residential development not to exceed 30 percent built -upon area;
(III) Land within the watershed shall be deemed compliant with the density requirements if the
following condition is met: The density of all existing development at the time of
reclassification does not exceed the density requirement when densities are averaged
throughout the entire watershed area at the time of classification; -
(IV) Cluster development is allowed on a project -by -project basis as follows: Overall density
of the project meets associated density or stormwater control requirements of this Section;
buffers meet the minimum statewide water supply watershed protection requirements;
built -upon areas are designed and located to rinimize stormwater runoff impact to the
receiving waters, minimize concentrated stormwater flow, maximize the use of sheet flow
through vegetated areas, and maximize the flow length through vegetated areas; areas of
concentrated development are located in upland areas and away, to the maximum extent
practicable, from surface waters and drsinageways; remainder of tract to remain in
vegetated or natural state; area in the vegetated or natural state may be conveyed to a

preservation easement; a maintenance agreement shall be filed .with the property deeds,
and; cluster development that mecca the applicable low density option requirements shall
transport stormwater runoff from the development by vegetated conveyances to the
maximum extent practicable;
(V) A maximum of 10 percent of each jurisdiction's portion of the:watershed outside of the
critical area as delineated on July 1, 1993 may be developed with new development
projects and expansions of existing development of up to 70 percent built -upon surface
area in addition to the new development approved in compliance with toe appropriate
requirements of Slab -subpart (d)(3)(B)(i)(1) or (d)(3)(B)(i)(II) of this Rule. For expansions
to existing development, the existing built -upon surface area is not counted toward the
allowed 70 percent built -upon surface area. A local government having jurisdiction within
the watershed may transfer, in whole or in part, its right to the 10 percent/70 percent land
area to another local government within the watershed upon submittal of a joint resolution
for review by the Commission. When the water supply watershed is composed of public
lands, such as National Forest land, local governments may count the public Iand acreage
within the watershed outside of the critical area in calculating the acreage allowed under
this provision. For local governments that do not choose to use the high density option

in that WS-II watershed, each project must, to the maximum extent practicable minimize
built -upon surface area, direct stormwater runoff away from surface waters and
incorporate best management practices to minimize water quality impacts; if the local
government selects the high density development option within that WS-II watershed, then
engineered stormwater controls must be employed for the new development;
(VI) If local governments choose the high density development option which requires
stormwater controls, then they shall assume ultimate responsibility for operation and
maintenance of the required controls as outlined in Rule .0104 of this Subchapter;
(VII) Minimum 100 foot vegetative buffer is required for all new development activities that
exceed the low density option requirements as specified in Sub -subparts (d)(3)(B)(i)(I) or
(d)(3)(B)(ii)(1) of this Rule; otherwise' a minimum 30 foot vegetative buffer for
development activities is required along all perennial waters indicated on the most recent
versions of U.S.G.S. 1:24,000 (7.5 minute) scale topographic maps or as determined by
local government studies; nothing in this Section shall stand as a bar to desirable artificial
streambank or shoreline stabilization;
(VIII) No new development is allowed in the buffer; water dependent structures, or other
structures such as flag poles, signs and security lights, which result' in only diminimus
increases in impervious area and public projects such as road crossings and greenways
may be allowed where no practicable alternative exists; these activities shall minimize
built -upon surface area, direct runoff away from the surface waters'and maximize the
utilization of BMPs;
(iQ No NPDES permits shall be issued for landfills that discharge treated leachate;
(ii) Critical Area Nonpoint Source and Stormwater Pollution Control Criteria:
(I) Low Density Option: New development is limited to either no more than one dwelling
unit of single family detached residential development per two acres (or 80,000 square foot
lot excluding roadway right-of-way) or six percent built -upon area.for all other residential
and non-residential development; Stormwater runoff from the development shall be
transported by vegetated conveyances to the maximum extent practicable;
(II) High Density Option: If new development density exceeds the low density requirements
specified in Subparagraph (d)(3)(B)(ii)(i), then engineered stormwater controls must be
used to control runoff from the first inch of rainfall; new residential and non-residential
development density not to exceed 24 percent built -upon area;

As of 1992, Lake James fully supported its designated uses. Portions of Lake James include
WS-V, B, and C classifications. The lake continues to provide the local area with a valuable
resource for recreation and a source of water supply. However, controversy currently exists
concerning the development of the watershed and potential impacts this development may have on
the aesthetic beauty and water quality in the future.
Lake Tahoma
Lake Tahoma, which is currently classified WS-I, B-Tr, was built in the 1920's to produce
hydroelectric power, but is now used for recreation. Owned by Lake Tahoma Incorporated, a
corporation of property owners living around the lake, Lake Tahoma covers'161 acres (65
hectares) and was most recently sampled in 1992. At that time, Secchi readings averaged 4.15
meters. Secchi readings in 1990 were among the highest measured in North Carolina (averaging
6.7 meters). Nutrients and chlorophyll a were low in 1990 and 1992, and the water column was
stratified and slightly acidic. Phytoplankton biovolume and density estimates from samples
collected in 1990 were low and the algal community was comprised of cryptophytes,
dinoflagellates (Peridinium wisconsinense) and oligotrophic indicators such as Din n sp.,
Mallamonas spp. and Ochromonas spp.' (chrysophytes). As of 1992, Lake Tahoma has been
evaluated to be. fully supporting its designated uses.

Lake Tahoma was built in the 1920's to
produce hydroelectric power, but it is now
used for recreation. It is owned by Lake
Tahoma, Incorporated - a corporation of
property owners living around the lake.
Secchi readings at Lake Tahoma were
among the highest ever measured in North
Carolina. The water column was stratified
and slightly acidic. Some musk grass (chara)
and water lilies (nymphaea) were found
along the shoreline. Nutrients and
chlorophyll -a were low.
Algal biovolumes and densities in Lake
Tahoma were also low. Cryptophytes were,
dominant at both stations, while Peridinium
wisconsinense, a common dinoflagellate, and
chrysophytes common to oligotrophic waters
inob on species, Mallomonas species and
Ochromonas species) were prevalent at the
upper station (CTBLT1). Gonyostomum
semen, a. large chloromonadophyte, accounted
for more than 50% of the algal biovolume at
downstream station, (CTBLT2).
A TSI of -4.1 indicates that Lake Tahoma is
oligotrophic. No violations of water quality
standards were noted and uses were fully
supported at the time of assessment.

Dear Dr. Cummings
& Ya.WA
IDEHNF1
March 21, 1996
Thank you for your interest in the water quality monitoring activities conducted on Lake
Tahoma. The Division of Environmental Management has conducted two water quality
surveys on your lake. The information collected during these monitoring activities is
attached for your use. I have also attached a brief explanation to assist you in developing
an understanding of the data which has been collected on the lake. As we discussed on the
telephone, you and your fellow lake shore homeowners may have some interest in
conducting further monitoring activities on Lake Tahoma. I would be willing to further
discuss your water quality concerns and the potential for conducting a homeowner based
monitoring program if your fellow neighbors are interested. I can be reached at
919/733-6510 if you are interested in further information.
Sincerely,
Jay H. S auber

RE: Approval to Impound - Lake George Dam I _ _ 1
McDowell County ? ' i, , S s;TroN
OFFICE
MCDOW-034-1 T-
Broad River Basin
Dear Mr. Holland:
This concerns the subject dam you recently repaired on Sally Branch in McDowell County
pursuant to issuance of an Approval to .Repair on January 25, 2001 as required by the Dam
Safety Law of 1967. As -built drawings and the engineer's certification were received on July
30, 2001. The dam was certified by Mr. J. C. Bumgarner, P. E. A final inspection of this dam
was made by Land Quality -Section staff of the Asheville Regional Office on August:10, 2001.
The dam was found to be in general conformance with the approved plans and specifications,
and you may impound water.
The Land Quality Section staff will make periodic inspections of this dam to assure that the dam
is being maintained in good operating condition. These inspections, however, will be relatively
infrequent. It'is advised that you closely inspect and.monitor your dam, and that you notify your
engineer and the Division of Land Resources if you see or suspect any problems concerning its
safety.
Sincerely,
James K. Leumas, P. E.
State Dam Safety Engineer
