PROJECT DESCRIPTION

Idols Hydroelectric Project, FERC No. 2585
PROJECT DESCRIPTION
The Idols Hydroelectric Project is located in the State of North Carolina, Counties of
Forsyth and Davie, on the Yadkin River, about 15 miles southeast of Winston- Salem, North
Carolina, and approximately 4 miles southeast of Clemmons, North Carolina.
The Project is a constructed development that was originally placed in operation by the
Fries Manufacturing & Power Company in 1898 with 8 turbine- generating units. Duke Power
Company's predecessor, the Southern Public Utilities Company, purchased the project in 1913
and replaced the turbine- generating units with 6 units of larger capacity by 1914. On July 28,
1980, Duke Power Company was issued a minor license by the FERC, effective April 1, 1962 and
terminating on July 31, 2000. Applicant purchased the project from Duke Power Company in
December 1996.
All lands necessary to operate and maintain the project are owned by Applicant in fee. By
agreement between Applicant and the City of Winston - Salem, the City uses Yadkin River water
behind the Idols impoundment free of charge as the source of its auxiliary water supply
Briefly described, the Project consists of (1) a long, low head, stone masonry dam across
the river channel that diverts a portion of the river's flow into a powerhouse located on the east
bank, and (2) a powerhouse containing inlet works, turbines, generators and transmission
equipment. Flows from the powerhouse discharge to a long tailrace before returning to the main
river channel. No major modifications to the Project have been made since the previous FERC
license application filed by Duke Power Company in 1966, and no additions or alterations are
proposed as part of this application

Clarification on Agency Comments:
1. Documentation is desired on how Duke Power ensures that
Idols Reservoir doesn't go below the Winston Salem water
intake level.
2. Include calculations in the documentation showing the
amount of -time, for the project to fill and spill, beginning
with a two foot drawdown and a 7Q10 flow. If the reservoir
is capable of filling and spilling in 2 hours or less under
those conditions (two foot drawdown and 7Q10 flow) then that
will help determine if the project approximates run -of-
river operation and help resolve downstream flow concerns.
It is also desired that Duke calculate how far the reservoir
could be drawdown in a 2 hour time under a 7Q10 flow
condition.
3. It was suggested that Duke plot the USGS gage readings
above and below the project during the low flow season. If
these plots indicate that the flow readings follow the same
relative pattern, then that will help resolve any downstream
flow concerns and help demonstrate that Idols has an
approximate run -of -river operation.
4. If the screening and flow criteria stated in the NCWRC
correspondence under the impingement and entrainment issues
is not met, then an assessment of the entrainment potential
and a calculation of the entrainment mortality potential,
based on turbine blade contact, will be an acceptable
approach to resolve the entrainment issue.
5. There is a need to determine the functionality of the
fish ladder. If the applicant will verify that the fish
ladder is non - functional, then the issue of upstream fish
passage can be closed.

Dear Mr. Oakley:
Thank you for your July 31, 1995, letter requesting comments on the First Stage Consultation
Report for Idols Hydroelectric Project (FERC #2585) and the invitation to the September 19,
1995, meeting regarding the relicensing of this project. The U.S. Fish and Wildlife Service
(Service) has reviewed the Report. These comments are provided in accordance with provisions
of the Fish and Wildlife Coordination Act (48 Stat. 401, as amended; 16 U.S.C. 661 et seq.),
Section 7 of the Endangered Species Act of 1973, as amended (16 U.S.C. 1531 -1543) and the
Federal Power Act, as amended (16 U.S.C. 79la- 825r).
The Idols Hydroelectric Project, located on the Yadldn River in Forsyth County, consists of a
low head, rubble masonry dam and a wooden powerhouse. The project functions in an
approximate run-of -river mode with project operation based on a daily inspection by an operator
who evaluates if the water level is suitable for production without impacting the City of Winston
Salem's water supply intake. The impacts of the approximate run -of -river mode vs. a true run -
of -river mode is of concern to the Service. It is our understanding that at times, no spill over
the dam occurs. Under this flow regime, the only flow entering into the bypassed reach is from
leakage; water passing through the fish ladder; water entering from Carter's Creek, or backflow
from the tailrace. Duke Power may need to conduct an instream flow study to determine the
requirements for flow within the bypassed reach. A site visit was scheduled for November 15,
1995, to observe the project during low flow conditions, but was canceled due to the lack of
suitable conditions. The Service is willing to participate and would appreciate prior notification
of a future site visit.
The Project contains a fish ladder at the midpoint of the spillway. At the September 19, 1995,
meeting and site visit, the operator stated that shad, presumably gizzard shad, orosoma

C
ianum) and white bass Mron e chry= use the fish ladder. Dube Power should evaluate
the ladder to determine the species that use the ladder and to what degree. Additionally the flow
required in order for the fish ladder to function effectively, as well as length of time this flow
exists during spawning periods for the species of fish found to be utilizing the ladder should be
determined.
The Report mentions that the Project contains a trashrack, however there is no information
regarding bar width, spacing, or flow velocity at this point. Inclusion of this information would
be useful in evaluating the potential for fish impingement and entrainment.
Another point of discussion at the September 19, 1995 meeting was the need to enhance public
access to the Yadkin River, Duke Power wished to discuss this topic at a later date. Currently
there is a canoe portage area around the Project's dam. The Service affirms the importance of
promoting quality wildlife experiences for all of our nation's citizens. To further this goal, the
Service would like to see Duke Power investigate ways to enhance public use of the Project
area.
Once again, thank you for the opportunity to provide comments on this project. We look
forward to working further with Duke Power in the relicensing process for the Idols
Hydroelectric ProjecL If you have any questions, please feel free to contact myself, or John
Ellis at the above address, or at (919) 856 -4520, ext. 26.

IDOLS HYDROELECTRIC PROJECT
STUDY PLANS AND INFORMATION
Low Flow Demonstration
Low flow demonstrations planned for earlier this year were
canceled due to high flow conditions. This demonstration
will be rescheduled during late May to early June 1996, when
flow conditions are more conducive to simulating a low flow
scenario. Duke Power Company will consult with NCWRR,
NCWRC, and USFWS personnel to reschedule this demonstration.
Fish Ladder Functionality
The USFWS requested verification relative to the
functionality of the fish ladder at the Project. The
applicant is not aware of any current or historical
utilization of the spillway fish ladder for upstream passage
at the Project. The only Yadkin River-species that might
benefit from upstream passage at the Project would be the
striped bass during upstream spawning migration.
In the late 1980's, the NCWRC investigated the feasibility
of establishing a self - sustaining striped bass population in
the Yadkin River. Upstream passage at the Project was a
consideration of this study. After conducting field surveys
of water velocities in potential striped bass spawning and
nursery areas, the NCWRC concluded that water velocities
were either inadequate or marginal to suspend striped bass
eggs and fry for successful propagation. Additionally,
research revealed that there were no documented cases where
fish ladders were utilized by striped bass. The NCWRC
concluded there was little likelihood of establishing a
self- sustaining population of striped bass within the Yadkin
River, and that the enhancement of the striped bass
population within the Yadkin River system may be
accomplished with alternative management methods.
Dissolved Oxygen Monitoring
The NCDWR, NCWRC, and USFWS have expressed concerns about
the dissolved oxygen levels in the bypass reach during the
low -flow period of the year. To address 'these concerns,
dissolved oxygen levels and water temperatures in the bypass
reach just downstream of the spillway will be monitored
during July- September 1996. Data will be collected with
Hydrolab Datasonde II® units installed in the bypass reach.

The exact monitoring location and placement of the Datasonde
II units will be determined during the low flow
demonstration scheduled during May or June 1996.
Two Datasonde II units will be placed in the bypass to-begin
data collection on July 1, 1996. The two units will be
placed in the same location to ensure continuous data
collection in the-event one of the units malfunctions. The
units will be programmed to collect data every 15 minutes.
With this frequency of data collection, the batteries in
each unit should provide nine consecutive days of operation.
To ensure uninterrupted data collection, however, both units
will be swapped out with new units every seven days. The
units will be returned to the laboratory where the data will
be downloaded, and the units will be cleaned, recalibrated,
and the batteries recharged for redeployment the following
week. This procedure will be repeated each week of the 3-
month study period.
The data collected over the 3 -month study period will be
analyzed to provide hourly averages for dissolved oxygen
(ppm) and water temperature (C). 'These data will be used to
determine diurnal and diel dissolved oxygen patterns in the
bypass reach during the low -flow period of the year. The
results of this study will be summarized and reported to the
NCDRR, NCWRC, and the USFWS.
Assessment of Entrainment
The NCWRC and the USFWS have both expressed concerns about
fish entrainment and mortality at the Project. The NCWRC
criteria for water intakes establish the maximum intake rack
bar spacing and water velocity as 2.5 in and 1.5 fps,
respectively. If these criteria can not be met for the
Idols Hydroelectric Project, then specific studies must be
conducted to address entrainment and entrainment mortality.
Due to the configuration of the powerhouse and the resulting
difficulty in conducting definitive entrainment studies,
both NCWRC and the USFWS have agreed that an assessment of
the entrainment potential and a calculation of the
entrainment mortality potential will be an acceptable
approach to address this issue. This approach is consistent
with the approach used for the Spencer Mountain
Hydroelectric Project.
Intake Velocity Determinations
The first step in addressing the entrainment issue will
consist.of an evaluation of the intake velocities and trash
rack spacing at the Project to determine consistency with _

the NCWRC screening and flow criteria. Intake velocities
will be determined by measuring velocities just upstream of
the trashrack of each operating unit under four -unit
operation. Due to the inclination of the trashracks,
velocity will be measured along a transect parallel to-the
intake, approximately 2 m upstream of the trashracks. A
rope will be stretched across the intake at this point to
allow measurements to be taken from a boat. The 16 -ft
diameter opening for each unit will be divided into 3 -ft
wide vertical strips, for a total of five strips per unit.
A Marsh- McBirneyo Model 201 flowmeter will be used to
measure velocity at 0.2 and 0.8 of the water depth within
each vertical strip. Velocity data will be summarized
separately for individual units and collectively for all
units. These data will be submitted to the NCWRC and USFWS
for their review.
Entrainment /Mortality Potential
If the trash rack spacing and intake velocities at the
Project exceed the NCWRC criteria, an assessment of the
entrainment potential and a calculation of the entrainment
mortality potential will be conducted. The assessment of
entrainment potential will consist of an electrofishing
evaluation of fish densities in the forebay of the Project
impoundment. The forebay fishery will be sampled with boat-
mounted electrofishing equipment. The shoreline and near -
shore area on the powerhouse side of the river will be
sampled from the intake to just upstream of the railroad
bridge (150 -m transect). Sampling will be conducted during
late May to early June, when fishes should be concentrated
in the near -shore area. All collected fishes will be
identified to species, measured for total length (mm), and
released. Data will be summarized to provide a qualitative
and quantitative (catch - per - unit -of- effort) assessment of
Y the forebay fishery.
The assessment of the entrainment mortality potential at the
Project will be conducted by calculating the probability
that an entrained fish will be struck by a turbine blade as
the fish passes through the Project's turbines. The
probability will be calculated using Von Raben's formula
(Cada 1990), based on fish size, turbine characteristics,
runner speed, and discharge. The evaluation will be
conducted for the range of species and sizes of fishes
collected during the forebay fish survey mentioned above.
The application of this formula will be the same as that
used for a similar determination at the Spencer Mountain
Hydroelectric Project. These data will be summarized to
provide an assessment of the entrainment mortality potential

for the species of fishes that would most likely be
entrained. These data and the forebay fish survey data will
be the basis for determining if there is a potential
entrainment /mortality problem at the Project.
Downstream Flow and Approximate Rua -of- River Operation
It was suggested that Duke plot USGS gage readings above and
below the project during low flow season. If these plots
indicate that the flow readings follow the same relative
pattern, then that will help resolve any downstream flow
concerns and help demonstrate that Idols has an approximate
run -of -river operation. Enclosed are plots of USGS gage
readings above (Eason Gage: drainage area = 1694 square
miles) and below (Yadkin College Gage: drainage area = 2280
square miles) the project during the low flow season. The
plots are historical daily mean flows from July 1 to
September 30 for the following years: 1980 - 1986; 1989 -
1991; and 1993. The data for the Enon gage for 1987 and
1992 and the data for the Yadkin College gage for 1988
during desired months was not included in the source of data
used, and therefore is not presented in this report..
Also enclosed is the calculation showing the amount of time
for the Project to fill and spill, beginning with a two foot
drawdown and a 7Q10 flow. It was discussed on February 12,
1996 that if the reservoir is capable of filling and
spilling in 2 hours or less under 7Q10 conditions, then that
will help determine if the project approximates run -of -river
operation and help resolve any downstream flow concerns.

SUBJECT: Study Plans for Idols Hydroelectric Project
FERC Project No. 2585
Dear Ms. Robinson:
This correspondence responds to a request by you for our review of Duke Power
Company's proposed study plans at the Idols Hydroelectric Project. The North Carolina Wildlife
Resources Commission is authorized to comment and make recommendations which relate to the
impacts of this project on fish and wildlife through the Federal License of Water Resource
Project Act (Federal Power Act -16 U.S.C. 791a et seq.), and the Fish and Wildlife Coordination
Act (48 Stat. 401, as amended; 16 U.S.0 661- 667d).
We find the study plans acceptable as written for the sections on low flow demonstration,
fish ladder functionality, and dissolved oxygen monitoring.
We recommend that the second paragraph under the subtitle Entrainment/Mortali1y
Potential within the section on assessment of entrainment be modified. At present, this section
states that fish sampling data will be used to calculate entrainment mortality potential by using
Von Raben's formula. Depending on the results of fish sampling upstream of the intake, we may
recommend that a site - specific mortality study be conducted. The presence of target species such
as federal or state listed species, certain game species, or critical nongame species would drive
our recommendation as to how to calculate a mortality estimate. In the absence of target species,
we would likely agree to using Von Raben's formula to estimate entrainment mortality potential.
We have discussed the section pertaining to downstream flow and approximate run -of-
river operation with personnel of the North Carolina Division of Water Resources (DWR). We

Idols Hydro Page 2 6/21/96
are not able to determine whether the operation of Idols Hydroelectric Project approximates run-
of-river or not using the gage information provided by Duke Power Company. We defer to
comments provided by the DWR in a memorandum to you dated 20 June 1996 for the method to
be used for making this determination.
Thank you for the opportunity to review and comment on these study plans. If you have
any questions regarding these comments, please contact Ms. Stephanie Goudreau at 704/652-

The Division of Water Resources (DWR) has reviewed the Study Plans and Information
Report for the relicensing of the Idols Hydroelectric Project, received May 20, 1996. The DWR
do not have any comments on the sections of the report dealing with fish ladder functionality,
dissolved oxygen monitoring, or the assessment of entrainment. Our primary concerns are related
to downstream flows and how project operations might impact those flows and their uses
The fill and spill calculations provided appear to be correct. These show that with a two -
foot drawdown and a 7Q 10 inflow, if the project went off line it would spill in about an hour and
a half and return to run -of -river downstream. These calculations were to assist in determining
what level of drawdown night be acceptable but do not directly relate to whether the project
approximates run -of -river operation
The DWR also reviewed the U S. Geological Survey (USGS) gage data provided in the
report These hydrographs show daily mean flows at the Yadkin College and Enon USGS gages
on the Yadkin River. We can not determine from these records of daily mean flows whether the
operation of Idols Hydro approximates run -of -river or not. We recommend plotting hourly flow
data for both gages for shorter periods (two weeks) during the low flow months of July through
October. An evaluation for these low flow periods from 1991 through 1996 should be made.
This evaluation should include hourly plots for the same time period of the water withdrawn by
Winston -Salem from Idols for water supply and the city's wastewater discharge to downstream
tributaries -

After reviewing the Idols Fast Stage Consultation Report the Division has expressed
concerns about the location of the dissolved oxygen (D.O.) monitoring stations described
in the report. Two NPDES permitted facilities discharge treated wastewater within the
Carters Creek watershed. Since Carters Creek joins the Yadkin River immediately
downstream of the spillway, the Division recommends that the D.O. monitoring station be
relocated downstream of the spillway within the bypass reach.
Duke Power has responded to the Division's concerns by proposing a study plan to
continuously monitor D.O. and temperature within the bypass reach. The Division has
reviewed and approves of the study plan submitted on May 16, 1996. Since the low flow
demonstration has been postponed twice, the proposed three month data collection period
will have to be shifted back in time compared to the time period outline in the study plan.
An appropriate starting time can be discussed during the low flow demonstration scheduled
for July 18; 1996.

We have received information concerning the above project from the State
Clearinghouse, as well as your letter of July 31, 1995.
The Idols Hydroelectric Plant (Fries Manufacturing and Power Company) was placed
on the North Carolina state study list on April 8, 1982, for potential nomination to
the National Register of Historic Places. The power plant is eligible for listing under
Criterion A for social history for its role in the development of the town of Winston
and Salem (Winston - Salem) into a significant manufacturing and industrial center,
and Criterion C for its engineering. It has been recognized by the American Society
of Mechanical Engineers as a regional historic mechanical engineering landmark.
We understand Duke Power intends to file an Application for New License, and is
not at this time proposing any structural changes to the historic plant. We have
determined the issuance of a new license will` have no effect upon the historic
plant. If any plans for structural changes are developed in the future we will need
to review the plans under Section 106 of the National Historic Preservation Act for
compliance with the Secretary of the Interior's Standards and Guidelines. We are
pleased the Idols Hydroelectric Plant will continue to be used for its historic purpose
of generating electricity.
The above comments are made pursuant to Section 106 of the National Historic
Preservation Act and the Advisory Council on Historic Preservation's Regulations

Re: Idols Hydroelectric Project, FERC No. 2585
Dissolved Oxygen Monitoring Program
Dear Mr. McDaniel:
We have completed the dissolved oxygen monitoring program for the Idols Project.
The results are provided herein.
Background
During first stage consultation for relicensing the Idols Project, the Division of Water
Quality requested that the relicense applicant ( "Applicant ") implement a monitoring program to
determine dissolved oxygen levels in the bypass reach during low flow periods of the year.
The data would be used by DWQ and other agencies to evaluate the suitability of summer
water quality conditions in the bypass reach for fishery and waste assimilation purposes under
the current (and proposed) mode of project operation
Applicant complied with this request by using continuous recorders to collect data at
15 minute intervals from July 1 through September 30, 1996. Unfortunately, above - average
river flows precluded evaluating the bypass under "worst - case" conditions, hampered the
deployment and retrieval of monitoring equipment, resulting in extended periods with no data
collection, and greatly affected the accuracy of the data through progressive fouling of the
sensor membrane. After reviewing the data, Applicant and DWQ determined: (1) the data was
not suitable for use in addressing the objectives of the monitoring program, and (2) a revised
monitoring program comprising the use of a hand -held meter to take measurements twice daily
would be better suited to the goals of the monitoring program
Measurement Procedures
Dissolved oxygen, water temperature and depth of water over the dam were measured
during the period June 26 through September 30, 1997. The DO and temperature
measurements were made in the morning and evening of each day using a YSI® Model 55
hand -held meter. The meter probe was attached to an extension pole and placed
approximately F below the water surface immediately downstream of the dam at the northeast
end (see Attachment 1). Probe membranes were changed every two to three weeks
Calibration was assured through the use of the built -in calibration chamber.

Results
River conditions this year were ideal for the purposes of our program. Exceptionally
low flows resulted in several consecutive days in August and September when no flows passed
over the dam. We were able to confirm that water backs up to the base of the dam under all
conditions and we were able to measure the effects on DO levels during prolonged periods
when no water is passing over the dam.
The data, provided in both tabular and graph form in Attachment 2, is consistent with
data gathered in the project vicinity in 1994: DO levels are relatively high, typically above 8
mA and show a slight diurnal trend, with levels generally higher in the morning than those in
the evening. We also found that DO levels dropped during periods when no flow passed over
the dam. However, the reductions were relatively modest, presumably due to moderating
effects of dam leakage and tailwater recirculation within the bypass reach.
Please provide any comments you may have as soon as possible. If you have any
questions, or require additional information, please feel free to call me.
Very truly you s,
