Background
Lake Alan Henry is a run -of -river reservoir formed by the John T. Montford dam on the Double
Mountain Fork Brazos River primarily in Garza County, Tex. (fig. 1) (Asquith and Vrabel, 2011).
The reservoir is operated by the City of Lubbock and has recently become an "online" municipal
water supply to the city. The City of Lubbock is interested in preserving and potentially enhancing
the quantity and quality of water in the reservoir. In order to address potential issues that could
affect the quantity and quality of water in the reservoir, water -resources management tools are
needed to enhance the scientific understanding of the hydrologic, sediment, and water -quality
processes in the watershed.

An issue of particular concern to water -resource planners with the City of Lubbock is the effects
of encroachment and proliferation of salt cedar in the Lake Alan Henry watershed. The watershed
is defined as the Double Mountain Fork Brazos River watershed upstream of John T. Montford
dam. Salt cedar, a member of the Tamarix species, is a nonnative plant commonly thought to
consume substantial amounts of water in riparian habitats and to reduce populations of native
vegetation species through vigorous growth and reproduction. The selective removal of woody
plants such as salt cedar with an intended effect to increase water yields to downstream water
resources is a brush -management conservation practice currently (2013) used in Texas (Natural
2
Resources Conservation Service, 2009; Texas State Soil and Water Conservation Board, 2013).
The Texas State Soil and Water Conservation Board (TSSWCB) Water Supply Enhancement
Program (WSEP) provides funding for brush management in an effort to increase water yields to
water bodies in Texas used for water supply. Watershed modeling feasibility studies (Bednarz and
others, 2000; Bumgarner and Thompson, 2012), some of which were conducted in landscapes
similar to that of the Lake Alan Henry watershed, are a required component of the application of
the WSEP and are tools used to identify where brush -management applications in a watershed
might most effectively increase water yields.
Problem
A watershed modeling tool has not been previously developed that can be used to help manage the
quantity and quality of water in the Lake Alan Henry watershed and reservoir. An additional
problem is that a watershed modeling feasibility study has not been completed for the Lake Alan
Henry watershed such that the City of Lubbock could use it for eligibility for the WSEP for brush -
management applications.
Objectives
The objective of this proposed study is to develop a calibrated watershed model of the Lake Alan
Henry watershed. City of Lubbock water -resource planners will be able to use results of the model
as a management tool and the model can be used to enhance the fundamental scientific
understanding of the watershed, including identification of data gaps. Additionally, because the
model will be used to simulate the potential effects of brush management on water yields to Lake
Alan Henry, the modeling study proposed herein will satisfy the feasibility -study requirements of
the WSEP.
Scope
The U.S. Geological Survey (USGS), in cooperation with the City of Lubbock Water Department
and TSSWCB (cooperators), proposes to develop a calibrated hydrologic model of the Lake Alan
Henry watershed and simulate the potential effects of brush management on water yields to the
reservoir. Model simulations of brush management (the replacement of salt cedar with grasslands)
will be completed and the effects of brush management on water yields to the reservoir estimated.
Also, in addition to water -yield and brush -management simulations, the watershed model will be
developed such that it can isolate and simulate watershed processes such as evapotranspiration,
subsurface infiltration, canopy interception, sediment loading, and water quality for future model
calibration and applications. The study is proposed to begin on October 1, 2013, will require 21
months to complete, and will cost $165,400.
Approach
In order to develop a useful water -resources management tool and simulate the potential effects of
brush -management on water yields in the Lake Alan Henry watershed, a Soil and Water
Assessment Tool (SWAT) (Arnold and others, 1998) watershed model will be developed and
calibrated and brush -management scenario simulations, in which land -cover model input is altered
to simulate the replacement of brush with native grasses, will be completed. SWAT is a process -
based, semi -distributed water balance model designed to predict the effects of management
decisions on water, sediment, and agricultural chemical yields. Tasks to complete the
3
investigation are: (1) Data acquisition, (2) model development, (3) model calibration, (4) scenario
analysis, and (5) interpretation and reporting.
Task 1: Data Acquisition
Time series and geospatial data are required for model development, calibration, and scenario
simulations. These data will be acquired in digital format. Available time series data include:
• Precipitation and air temperature data from sources such as USGS, Texas A&M
University, and National Climatic Data Center; and
• streamflow data from the USGS streamflow-gaging station 08079600 Double Mountain
Fork Brazos River at Justiceburg, Tex., which is the sole streamgage in operation (since
1961) in the study area.
Available geospatial data include:
• Locations of streamflow-gaging and climate stations;
• 10-meter National Elevation Dataset (NED);
• Soil Survey Geographic (SSURGO) database;
• National Land Cover Dataset (NLCD) 2006; and
• Texas Parks and Wildlife Department Texas Ecological Systems Dataset (TESD), which,
where available, will be used to refine the resolution of the NLCD.
Task 2: Model Development
The SWAT watershed model is a process -based, semi -distributed water balance model designed
to predict the effects of management decisions on water, sediment, and chemical yields (Arnold
and others, 1998). In SWAT, a delineated watershed is divided into subbasins, each identified by a
single reach. Each subbasin is further divided into hydrologic response units (HRUs) that consist
of unique combinations of land cover, soil characteristics, land slope, and land -management
criteria. Default values are assigned to the model parameters by the modeling software based on
the unique HRU characteristics. Processes including, but not limited to, surface runoff,
evapotranspiration, base flow, channel transmission losses, the life cycle of plants, nutrient
cycling, and constituent transport can be simulated for each HRU and are determined by the
process -related parameter values uniquely defined for each HRU. The simulated water and
constituent loads are aggregated within their corresponding subbasins, are allocated to the
subbasin reach, and exit a subbasin through outlet points on the stream network that define the
subbasin. Model output includes streamflow and constituent loads for any subbasin outlet,
including the delineated watershed outlet, at variable timesteps from sub -daily to annual.
Where possible, the Lake Alan Henry watershed model will also incorporate reservoirs and playas
(surface depressions that often intercept and store rainfall -produced runoff) as well as estimates
for crop irrigation. Also, the area of the drainage basin upstream from station 08079600 is 1,466
mil; however, 1,222 mil of this is located on the caprock and is likely noncontributing. Finally,
long-term climate data such as precipitation and temperature collected within the study area will
drive the model.
Task 3: Model Calibration
The Lake Alan Henry watershed model will be manually calibrated to at least 15 years of
streamflow data collected at the Double Mountain Fork Brazos River at Justiceburg streamflow-
gaging station, which is about 4 miles upstream from Lake Alan Henry. Manual calibration of a
SWAT model consists of adjusting process -related parameter values to minimize the differences
between simulated output and measured data. Model performance will be evaluated with several
2
criteria for goodness of fit: the percent bias of simulated output to measured data, the coefficient
of determination (R-squared) of the linear regression, and the Nash -Sutcliffe coefficient of model
efficiency. These criteria are an expression of uncertainty in the model.
Task 4: Scenario Analysis
Following model calibration, the USGS will simulate the potential effects of brush management
on water yields to Lake Alan Henry. The watershed will be subdivided to create a to -be -
determined number of brush -management subbasins. Modified land -cover input datasets (brush
land cover replaced by native grassland) will be created to estimate the potential for brush
management in each of the delineated brush -management subbasins. Simulated water -yield
changes will be calculated as the difference between the water -yield and streamflow outputs from
the brush -management simulation and the water -yield and streamflow outputs from the
unmodified model simulation. Ultimately, these simulated changes in water yields provide
estimates of potential changes with a certain degree of uncertainty that will be identified as part
the model calibration process (task 3).
Task 5: Interpretation and Reporting
At the conclusion of modeling effort, interpretations of the scenario simulations as well as the
methods used for data acquisition and model development, calibration, and simulations will be
documented in a USGS Scientific Investigation Report (SIR). The simulation output will be used
to assess the potential effects of brush management on hydrologic processes and watershed
dynamics.
Quality Assurance Plan
Quality assurance (QA) measures will be followed to ensure the completeness of the information
communicated during the study. The QA objectives for the collection and communication of
information will:
• Withstand scientific scrutiny;
• Be obtained by methods appropriate for its intended use; and
• Be representative and of known completeness and comparability.
All digital data and models will be reviewed by USGS personnel to ensure proper documentation.
The project and project budget will be reviewed by USGS management on a quarterly basis to
ensure project timelines are met.
Relevance and Benefits
This study will produce a tool to help resource managers better understand and manage the
surface -water resources in west Texas. Specifically, development of a watershed model will help
guide brush -management applications that will potentially increase water yields to Lake Alan
Henry. The model can also be used in future applications to understand processes that affect
sediment transport and water -quality in the watershed and reservoir. Results from this study will
benefit the USGS Strategic Directions Program by characterizing an area where there are critical
water -resources issues and adding to the scientific body of knowledge in the region.
Deliverables
Preliminary, tabulated results of the brush -management simulations will be provided to the
cooperators by the end of the fourth quarter of FY15 (September 30, 2015) so that they can
5
reference the results when planning brush -management applications. Model development,
calibration, and simulation methods, results, and interpretations will be documented in a USGS
Scientific Investigations Report (SIR). The report will be approved for publication by the end of
the second quarter of FY16 (March 31, 2016).
Timeline and Budget
The study is proposed to begin in the first quarter FYI (October 1, 2013) if funded. Preliminary,
tabulated simulation results will be provided to the cooperators by the end of fourth quarter of
FYI (September 30, 2015) and a USGS SIR will be approved for publication by the end of the
second quarter of FY16 (March 31, 2016). The total cost of the project is $165,400 ($100,400
from the City of Lubbock, $50,000 from TSSWCB, and $15,000 from the USGS).
