STATEMENT OF COMMITMENT BY THE DISTRICT
The Hickory Underground Water Conservation District No. 1 strives to conserve, preserve, prevent waste, protect, and recharge the underground waters of all aquifers within the legal boundaries, as far as practicable to minimize the draw-down of the water table and the reduction of artesian pressure within the District Boundaries.
This amended plan becomes effective upon approval by the Board of Directors and remains in effect until an amended plan is approved or December 1, 2013, whichever is later. The plan may be revised at anytime, or after five years when the plan will be reviewed, revised or amended and is approved as administratively complete by the Texas Water Development Board.
At the request of area citizens, the Texas Water Development Board entered an order on December 29, 1975, delineating a subdivision of the Hickory Aquifer Underground Water Reservoir in Concho, Kimble, Llano, Mason, McCulloch, Menard and San Saba Counties. In November 1981, a petition was submitted to the Texas Water Commission calling for the creation of the Hickory Underground Water Conservation District No. 1 (District). At a hearing on June 9, 1982, before the Texas Water Commission the petition was granted and the District thus created.
The confirmation election required by state statute
was held on August 14, 1982; the District was officially established with a 94%
approval of voters in those areas of
Concho, Kimble, Mason, McCulloch, Menard and San Saba within the District
boundaries.
On August 12, 1999 the
petition of creation was amended by the TNRCC (now Texas Commission on
Environmental Quality) to include all aquifers within the legal boundaries and
management jurisdiction of the District.
On January 11, 2003, landowners of Mason County
petitioned the District to annex the remainder of Mason County not currently in
the District, and on May 03, 2003, in a special election held at the Mason
County Courthouse the remainder of Mason County was annexed into the District
with approval of 88% of the voters.
Regional
Cooperation and Coordination
Regional Water Planning Groups
In 1998 the District was apportioned into two Regional
Water Planning Groups established pursuant to § 16.053 of the Texas Water Code Concho, Kimble, Mason, McCulloch and
Menard are located in Region F and San
Saba County is in the Lower Colorado Regional Water Planning Group (Region K).
The District’s Regional planning responsibilities are within a 46-county area,
stretching from Matagorda Bay to the Pecos River in West Texas.
Groundwater Management
Area 7
In 2003 the Texas Water Development Board designated
the boundaries of 16 groundwater management areas in Texas. The District lies
entirely within Groundwater Management Area 7, which encompasses 34 counties
and 21 groundwater conservation districts within an area of approximately
42,000 square miles. The groundwater management area was designated for the
Edwards-Trinity aquifer, but also includes all or portions of the minor
Lipan-Kickapoo, Hickory, Ellenburger-San Saba, and Dockum aquifers, as well as
a small portion of the Ogallala aquifer,
The District participates in the mandatory joint
planning process mandated by 36.108 of the Texas Water Code and is actively
working with the other 20 GMA- 7districts to develop Desired Future Conditions
for the Edwards-Trinity aquifer. The
District is also meeting with relevant GMA 7 districts and conferring regularly
with the Texas Water Development Board to establish Desired Future Conditions
and assist in the calculation of Managed Available Groundwater for the Hickory
and Ellenburger-San Saba aquifer formations, for which Groundwater Availability
Models are not available, nor are any scheduled for completion before the end
of 2010 when initial DFCs must be submitted to the Board
West Texas Regional
Groundwater Alliance
The District is a member of the West Texas Regional
Groundwater Alliance. The regional alliance consists of seventeen (17) locally
created and locally funded districts that encompass almost 8.75 million acres
or 13,000 square miles of West Texas. This West Texas region is as diverse as
the State of Texas, making it necessary for each member district to develop its
own unique priority management goals and rules to best serve the needs of its
constituents.
In 1988, four (4) groundwater
districts; Coke County UWCD, Glasscock GCD, Irion County WCD, and Sterling
County UWCD signed the original Cooperative Agreement. Since then the number of
groundwater conservation districts in the area has more than quadrupled. The
current member districts are:
|
Coke County UWCD |
Crockett County GCD |
Glasscock GCD |
|
Hickory UWCD |
Irion County WCD |
Lipan-Kickapoo WCD |
|

Menard County UWD |
Lone Wolf GCD |
|
Hill Country UWCD |
Jeff Davis County UWCD |
Middle Pecos GCD |
|
Permian Basin UWCD |

|
The Alliance was created to implement common
objectives of coordinating and facilitating the conservation, preservation, and
beneficial use of water and related sources. Local districts monitor the
water-related activities of the farming and ranching, oil and gas, industrial
entities and municipalities
The Hickory Underground Water Conservation District
No. 1 is located near the geographical center of Texas and is comprised of
approximately 1,683,080 acres, including portions of: McCulloch, Menard,
Kimble, San Saba, Concho counties and the entirety of Mason County. In 2003 the
District gained approximately 433,000 acres with the annexation of the
remainder of Mason County that had not been included when the District was
initially created.
Principal industries of the District are listed in the table below. The District's economy is based to a large degree on agriculture; 12% of the acreage in the District is cropland. Principal municipalities in or near the district boundaries are Brady, San Saba, Mason and Eden.

Statement of Guiding Principles
The Hickory Underground Water Conservation District
No. 1 (District) is created and organized under the terms and provisions of
Article XVI, Section 59, of the Constitution of Texas and Chapter 36 (formerly
Chapter 52) of the Texas Water Code, Vernon's Texas Civil Statutes, and the
District’s actions are authorized by, and consistent with this constitutional
and statutory provision, including all amendments and additions. The District
is created for the purpose of conserving, preserving, recharging, controlling
subsidence, protecting and preventing waste and as far as practicable to
minimize the drawdown of the water table and the reduction of artesian pressure
of all Aquifers within the district boundaries. In order to carry out its
constitutional and statutory purposes, the District has all the powers
authorized by Article XVI, Section 59, of the Texas Constitution, and Chapter
36 of the Texas Water Code, Vernon's Texas Civil Statutes, together with all
amendments and additions.
The District's purposes and powers are implemented
through promulgation and enforcement of the District's regulations. These
regulations are adopted and revised under the authority of Subchapter E,
Chapter 36, Texas Water Code, and are incorporated herein as a part of the
District's management plan.
The District is within the Colorado River basin and
is bisected by the Llano and San Saba Rivers, as well as numerous other creeks.
Drainage is typically from west to east.
There are two major geologic features within the District. The Llano Uplift
(Central Basin) is in the eastern and southern portions of the District. This
feature is made up of ancient Cambrian rocks ranging in age from 1.0 to 1.2
billion years old and comprises granite and older metamorphic rocks. The
northern and western parts of the District are in the Edwards Plateau region
and are made up of Cretaceous Age limestone, dolomite, and marble.
The District elevation ranges from 1,100 to 2,300 feet above sea level.
Groundwater Resources of the Hickory Aquifer2
The Hickory Aquifer is the primary source of the
District’s groundwater, which is used for irrigation, public water supply,
industrial, stock, and the domestic needs of the people and entities served.
The Hickory Aquifer occurs in parts of the counties in the Llano uplift region
of Central Texas. Discontinuous outcrops of the Hickory Sandstone overlie or
flank exposed Precambrian rocks that form the central core of the uplift. The
down dip artesian portion of the aquifer encircles the uplift and extends to
maximum depths approaching 4000 ft. Most of the water pumped from the aquifer
is used for irrigation. The largest capacity wells, however, have been
completed for municipal water supply and industrial purposes in the Mason, Eden
and Brady area.
The Hickory Sandstone Member of the Cambrian Riley
Formation is composed of some of the oldest sedimentary rocks found in Texas.
In most of the northern and western portions of the aquifer, the Hickory can be
differentiated into lower, middle, and upper units, which reach a maximum
thickness of 480 feet in southwestern McCulloch County. In the southern and eastern
extent of the aquifer, the Hickory consists of only two units. Extensive block
faulting has compartmentalized the Hickory Aquifer, thus restricting hydrologic
connection from one area to another.
The Edwards-Trinity Plateau Aquifer underlies the
Edwards Plateau east of the Pecos River and the Stockton Plateau west of the
Pecos River, supplying water to all or parts of 38 counties.
The aquifer consists of saturated sediments of lower
Cretaceous age Trinity Group formations. Natural chemical quality of water
ranges from fresh to slightly saline. The water is typically hard and may vary
widely in concentrations of dissolved solids and bicarbonate. The salinity of
the groundwater tends to increase toward the west.
Well yields are typically low in the eastern portion
of the Edwards-Trinity, consequently there is little pumpage from the aquifer
within the District. Nevertheless, in some instances water levels have declined
as a result of pumpage. Historical declines have occurred in the northwestern
part of the District. Rapid population migration from the cities of Austin and
San Antonio will add considerably to usage.
The Ellenburger-San Saba Aquifer underlies 4,000
square miles in parts of 15 counties in the Llano Uplift area of Central Texas.
Discontinuous outcrops of the aquifer generally encircle older rocks in the
core of the Uplift. The remaining down-dip portion contains fresh to slightly
saline water to depths of approximately 3,000 feet below land and surface.
Water produced from the aquifer has a range in dissolved solids between 200 and
3,000 mg/l, but usually less than 1,000 mg/l. The quality of water deteriorates
rapidly away from the outcrop areas. Approximately, 20 miles of more down-dip
from the outcrop, water is typically unsuitable for most uses.
Most of the deep municipal wells, which supply the City of Brady, produce an
unknown amount of water from the Ellenburger-San Saba sequence of rocks. A
large portion of the water supply for the City of San Saba is believed to be
from the Ellenberger-San Saba and Marble Falls Aquifer.
The Marble Falls Aquifer occurs primarily in the
portions of McCulloch and San Saba counties within the District. Smaller
amounts of water are also used for rural domestic supplies, watering of
livestock and irrigation. Only small portions of Mason and Kimble counties are
affected by this aquifer.
The Marble Falls Aquifer occurs in several outcrops, primarily along the
northern and eastern flanks of the Llano Uplift Region of Central Texas.
Groundwater occurs in fractures, solution cavities, and channels in the
limestone of the Marble Falls Formation of the Pennsylvanian Bend Group.
Maximum thickness of the formation is 600 feet. Numerous large springs issue
from the aquifer and provide a significant part of the base-flow to the San
Saba River in McCulloch and San Saba counties and to the Colorado River in San
Saba and Lampasas counties.
Existing data for the Marble Falls aquifer show that
it contains mostly fresh water in outcrop areas and becomes mineralized a short
distance down-dip from the outcrop areas. However, very few data exist to
evaluate the brackish water that is present.
Most wells producing from the Marble Falls aquifer produce fresh groundwater on
the outcrop, while groundwater becomes highly mineralized within a relatively
short distance of the down-dip. However, because the areal extent of the Marble
Falls aquifer is relatively limited, and because much of the existing data
indicate that the aquifer has limited groundwater availability, the Marble
Falls aquifer must be considered a very limited source of brackish groundwater.
Due to the presumed deep nature where brackish groundwater would be located,
and the low productivity of the aquifer, relative costs are expected to be
moderate to high.
Managed Available Groundwater in
District Aquifers
The District is actively participating in joint
planning with 20 other groundwater districts in GMA 7 pursuant to Section
36.108 of the Texas Water Code, but Desired Future Conditions for District
aquifers within the management area have not yet been adopted and are not due
to the Texas Water Development Board until 2010. Once the desired future
conditions have been adopted by GMA 7, an estimate of the managed available
groundwater can be determined. The District may amend the management plan at
that time.
Methodology for Calculating District
Water Supply and Demand
Irrigation and Livestock: Irrigation and livestock numbers for counties are
allocated to the District in proportion to the percentage of the area of the
respective counties within the District as follows: Concho, 11.43%; Kimble,
2.55%; Mason, 100%; McCulloch 73.03%; Menard, 13.45%; San Saba, 55.71%.
Mining, Electric Generation and Manufacturing: No mining, electric generation or manufacturing takes place within the District in Concho, Kimble and Menard Counties. All mining in Mason, McCulloch and San Saba counties takes place within District boundaries. Electric generation estimates for Mason, McCulloch and San Saba Counties are included within District boundaries, but all estimates are zero. All manufacturing in Mason, McCulloch and San Saba counties takes place within the District.
Municipal
and County Other:
The municipalities of Brady (McCulloch County), Eden (Concho County), Mason
(Mason County), and San Saba (San Saba County), and the Millersview-Doole WSC
(Concho and McCulloch Counties) and Richland SUD (San Saba and McCulloch
Counties) are within District boundaries and are included in the respective
data tables. The municipalities of Junction (Kimble County) and Menard (Menard
County) are outside of District boundaries and are excluded from the data
tables. The county data for the County Other Water user Group is apportioned in
all counties based upon the percentage of county area located within the
District. See the Irrigation and Livestock methodology discussion for the
respective percentage values.
District
totals within tables may vary by an acre-foot due to rounding of numbers.

Surface
Water Resources of the Hickory UWCD No. 1
The only surface water impoundment used for purposes
other than livestock consumption is Brady Lake. The normal pool capacity is
30,000 acre-feet with a calculated annual firm yield of 2,2528
acre-feet. Currently the City of Brady is not utilizing this water; however the
city will construct a 3mgd R.O. Treatment Plant to provide the City of Brady
adequate water supplies to blend with the Hickory Aquifer wells in order to
maintain a Radium 226/228 level below state and federal standards. Current Brady
Lake pumpage is approximately 9 acre-feet annually for domestic purposes.
The San Saba and Llano Rivers bisect the District;
however, only a small amount is used for other than livestock and domestic
purposes.
