Subject: Beaver Lake Modeling Contract, United States Geological Service (USGS), $19,600 Relating to White
River Water Quality Standards Petition to Arkansas Pollution Control and Ecology Comrnission (APCEC)
RECOMMENDATION
City Administration recommends approving a contract with the United States Geological Service (USGS), for
$19,600 to model the upper end of the Beaver Reservoir, as impacted by and relating to the White River Water
Quality Standards Petition to the APCEC, and approving a $4,000 contingency.
BACKGROUND
ADEQ has informed the City that the Noland WWTF National Pollutant Discharge Elimination System (NPDES)
permit, currently being developed by ADEQ and scheduled for issuance in May, 2011, will contain limits on total
dissolved solids (TDS), chloride (CO, and sulfate (SO4), unless other actions are taken. The segment of the White
River where the Noland plant discharges is on the 303(d) impaired streams list for turbidity, TDS, cr, and SO4.
Measured concentrations in the White River exceeded current site specific water quality standards (WQS) of: Cl- -20
mg/1; SO4- -20 mg/1; and TDS -160mg/1. The least cost and most common solution, recommended by ADEQ and
recently successfully completed by Jonesboro, is to make a third party petition to the APCEC requesting Regulation 2
be changed by modifying the site specific water quality standards. It involves performing a Use Attainability
Analysis (UAA), a physical study of the river. Huntsville is facing a similar issue in their NPDES permit renewal.
The Beaver Water District (BWD), in formal written public comment, suggested that the APCEC would likely want
to know the impact of this type water quality change upon the Beaver Reservoir, down to the BWD water intake.
DISCUSSION
City staff discussed the potential impacts on the reservoir with ADEQ and regional water quality professionals, and
determined that the USGS had the most up-to-date and accurate model of the reservoir. As the USGS is an agency of
the federal government, no selection process is required. Staff met with Reed Green, the USGS representative, to
develop a scope of work that would meet the objectives relating to the APCEC petition and answer questions from all
interested parties.
Under this contract, USGS will model the upper end of Beaver to determine what impact, if any, the City's request to
modify the water quality standards will have on the reservoir at the BWD water intake structure. The BWD intake is
the most upstream of the four water treatment plant intakes in Beaver. The model information will be incorporated
into the overall petition to the APCEC to provide the most complete information to the Commission to aid in their
decision making.
BUDGET IMPACT
Funds are available within the project budget.

Ambient Conditions of Chloride, Sulfate, and Total Dissolved
Solids, and Fate and Transport Simulations in Beaver Lake,
Northwest Arkansas, 2006 — 2010
Submitted by U.S. Geological Survey
To the City of Fayetteville
March 18, 2011

Introduction
Beaver Lake, completed in 1963, is located in northwest Arkansas and receives most of its water from
three tributaries of the White River (White River, Middle Fork White River, and West Fork White
River), Richland Creek, and War Eagle Creek (fig. 1). The drainage area of Beaver Lake is 3,087 km2,
1,067 km2 from the White River drainage, 143 km2 from the Richland Creek drainage, and 860 km2
from the War Eagle drainage. Beaver Lake covers 11,420 hectares, and contains 2.04x109 in3 of water
at normal pool elevation.
The Beaver Lake watershed was selected as the number one priority watershed in Arkansas' Unified
Watershed Assessments and Restoration Priorities report prepared by representatives from various state
and federal agencies (http://arkansaswater.org/reports/1998Assesment.pdf). Beaver Lake watershed was
selected as the number one priority because it contained a state extraordinary water resource, an
imperiled aquatic species, drinking water supplies serving a population over 250,000, a state impaired
water body, numerous state waters of concern, three U.S. Department of Agriculture Environmental
Quality Incentive Program projects, a 319 non -point source priority area, and an interstate waters of
concern.
Beaver Lake serves as the source -water supply for over 375,000 customers in northwest Arkansas. Four
drinking -water utilities withdrawal water from the 1.59x108 m3 of allocated storage. The major supplier
is Beaver Water District (300,000 customers), followed by the rural and economically disadvantaged
Benton -Washington Regional Public Water Authority (35,000), Carroll -Boone Water District (30,000),
and Madison County Regional Water District (10,000). Beaver Lake also serves as a major resource for
aquatic recreation and provides both cold- and warm -water fisheries. Downstream from Beaver Lake
Dam, is a major trout fishery.
USGS has been collecting water -quality samples and monitoring water quality in Beaver Lake arid its
tributaries since 2001 in cooperation with Beaver Water District (fig. 1). Using data prior to April 2003,
the USGS developed and calibrated a numerical model of hydrodynamics and water quality (Galloway
and Green, 2006). This model was later used to evaluate simulated changes in input water quality,
mainly nutrients and suspended sediment (Galloway and Green, 2007). The results from the model
simulations were later used in the development of nutrient and turbidity criteria and standards for Beaver
Lake. Similar model simulations can be developed and evaluated for total dissolved solids.
Purpose and Scope
The purpose of the proposed project is to describe ambient conditions of chloride (C1), sulfate (SO4), and
total dissolved solids (TDS) concentrations in Beaver Lake for the period 2006 through 2010, and
update the calibrated and published 2001-2003 Beaver Lake CE -QUAL -W2 model of hydrodynamics
and water quality (Galloway and Green, 2006) to include CL, SO4, and TDS simulations for this same
time period. The simulated timeframe will be updated to include 2006 through 2010 calendar years.
This timeframe includes extremely dry and wet hydrologic time periods. Five different CL, SO4, and
TDS wastewater treatment input scenarios will be constructed, run, and evaluated against the
2
'calibratedor base model. Wastewater inputs will enter into the model at the upstream White River
boundary. Similarities and differences between the scenarios and the base -line condition for CL, SO4,
and TDS concentrations will be examined through time at various downstream locations in Beaver Lake
and at different depths. Model setup and simulations will be completed by end ofJune, 2011. A report
will be prepared and published by the end of September, 2011.

Approach
Existing Beaver Lake CE -QUAL -W2 hydrodynamic and water -quality model -- A two-
dimensional, laterally averaged, hydrodynamic and water -quality model using CE -QUAL -W2 Version
3.1 (Cole and Wells, 2003) was developed for Beaver Lake and calibrated based on vertical profiles of
temperature and dissolved oxygen, and water -quality constituent concentrations collected at various
depths at four sites in the reservoir from April 2001 to April 2003 (Galloway and Green, 2006). The
Beaver Lake CE -QUAL -W2 model simulates water -surface elevation and vertical and longitudinal
gradients in water -quality constituents. The model includes routines for 18 state variables in addition to
temperature, including any number of inorganic suspended solids groups, phytoplankton groups,
nitrogen and phosphorus species, dissolved and particulate organic matter, total inorganic carbon,
dissolved oxygen, and organic sediments. Additionally, over 60 derived variables can be computed from
the state variables (Cole and Wells, 2003).
The computational grid is the geometric scheme that numerically represents the space and volume of the
reservoir. The model extends 80 km from the upstream boundary (White River at the Highway 45
bridge) to the Beaver Lake dam (figs. 1 and 2). The grid originally was developed by Haggard and
Green (2002) to simulate the hydrodynamics and distribution of temperature and dissolved oxygen in
Beaver Lake for calendar years 1994 and 1995. Thirty-five computational segments exist along the
mainstem of the White River in Beaver Lake and 12 computational segments are in War Eagle Creek. In
addition, four other downstream branches are modeled with three computational segments each.
Volumes of the smaller embayments not included in the computational grid were added to associated
mainstem segments so that reservoir volume was preserved. Each segment was divided vertically into 1-
m layers. Two tributaries also were included in the model at the most upstream segment. Tributaries
allow for the application of boundary conditions to the grid without affecting the geometry. One
tributary was used to simulate the input from the Fayetteville wastewater -treatment plant discharge at
the upstream segment and another to simulate the inflow from Richland Creek. A third tributary was
used to simulate the inflow from Prairie Creek (fig. 1).
Daily reservoir inflows used in the model were obtained from streamflow-gaging station data on the
three main inflows (White River, Richland Creek, and War Eagle Creek) and were estimated for the
three smaller branches. The mean daily streamflow recorded for War Eagle Creek (site S3) was used to
estimate the streamflow for the other three other branches based on their respective drainage areas.
Streamflow gaging station data were used to simulate inflow from the Prairie Creek tributary from April
2001 to October 2001. Because the gaging station was discontinued, streamflow was estimated from
October 2001 to April 2003.
The downstream boundary for the Beaver Lake model consists of the outflow from Beaver Lake dam.
Hourly outflow data was produced by the USACE using stage -discharge relations and hourly power
generation records for the period of April 2001 to April 2003 (John Kielczewski, U.S. Army Corps of
Engineers, written commun., 2003). The release structure (penstock) was simulated as a point release,
and the middle of the structure was at an elevation of 302.2 m above NGVD of 1929, model layer 45
(fig. 2).
4
Other hydraulic boundaiy conditions included water withdrawal by four public water -supply districts
(Beaver Water District, Carroll -Boone County Water District, Madison County Water District, and
Benton -Washington County Water District). Withdrawal rates for each water -supply district were
variable by month and based on reported 2001 through 2003 monthly intakes (Terrance W. Holland,
U.S. Geological Survey, written commun., 2004).
Hydraulic boundary conditions at the water surface included evaporation, wind stress, and surface heat
exchange. Meteorological data required for these computations were measured at the Northwest
Arkansas Regional Airport (fig. 1) (National Climatic Data Center, Asheville, North Carolina, written
commun., 2004) and generally were recorded at hourly intervals.
Hourly inflow water temperatures were estimated from the meteorological data and from periodic
measurements at the three main inflow sites (White River, Richland Creek, and War Eagle Creek).
Water temperatures for the smaller tributaries were estimated only from the meteorological data.
Initial water -surface elevation, water temperature, and constituent concentrations for each model
segment are required at the start of a model simulation. Initial water -surface elevations were set to the
measured value on April I, 2001. Beaver Lake was assumed to be in isothermal conditions throughout
the entire reservoir and equal to 6 °C. Initial constituent concentrations also were assumed to be
uniform, and concentrations measured at the five sampling sites on March 30, 2001, were used as the
initial values.
Future Total Dissolved Solids Simulations — The original Beaver Lake CE -QUAL -W2, version 3.1
model has been updated to version 3.6. Boundary conditions and the new simulation time frame will be
updated for the period January 1, 2006 through December 31, 2010. Initial conditions will be set for
January 1, 2006. CL, SO4 and TDS were not simulated in the original 2001 — 2003 model. The CL, SO4
and TDS 'switches' will be tuned on in the model for the purposes of this study. CL, SO4 and TDS
(dried at 180 degrees F) concentrations are analyzed along with the other water -quality constituents from
water -quality samples collected at the sites in Beaver Lake. Boundary and initial conditions will be
prepared for the 2006-2010 time period to provide a base -line model. Simulated CL, SO4 and TDS
values will be compared against measured values at the various water -quality monitoring sites at the
various depths in Beaver Lake for model validation and sensitivity. Time -series plots of simulated and
measured values will be prepared to show similarities and differences.
Five CL, SO4 and TDS discharge scenarios from the Fayetteville wastewater treatment plant, provided
by the City of Fayetteville, will be run and results compared against base -line model results. Time -
series plots of concentrations at specific points in Beaver Lake for the five different CL, SO4 and TDS
scenarios will be prepared to show similarities and differences in scenario runs. Color contour plots of
CL, SO4 and TDS concentrations from upstream to downstream, surface to bottom of Beaver Lake will
show the fate and extent of CL, SO4 and TDS concentrations over time throughout Beaver Lake.
Results of the base -line model and five CL, SO4 and TDS model simulations will be presented in a
USGS Scientific Investigations Report (digital format (pdf), only), and made available to the City of
Fayetteville and the public, in general.
