XIII Senate
The
Pecan Valley Groundwater Conservation District (District) provides for the
conservation, preservation, protection, recharging, and prevention of waste of
the groundwater within the defined boundary of the District, through sound
management strategies, while protecting private property rights.
The Pecan Valley Groundwater Conservation District
will pursue this goal through the gathering of scientific data regarding the
hydrological characteristics of the Chicot, Evangeline and Jasper aquifers that
underlie DeWitt County, and the adoption and enforcement of fair and
appropriate rules governing well spacing and production and use of the
groundwater, and through a monitoring program to manage groundwater withdrawal
within the district to a sustainable yield of the aquifer
II. PURPOSE
OF THE MANAGEMENT PLAN
Senate Bill 1 (SB 1), enacted by the 75th Texas
Legislature in 1997, and Senate Bill 2 (SB 2), enacted by the 77th Texas
Legislature in 2001, established a comprehensive state-wide water resource
planning process and the actions necessary for groundwater conservation
districts to manage and conserve the groundwater resources of the state of
Texas. These bills require all
groundwater conservation districts to develop a management plan which defines
the groundwater needs and groundwater supplies within each district and the
goals each district has set to achieve its mission. In addition, the 79th Texas Legislature
enacted HB 1763 in 2005 that requires joint planning among districts that are
in the same Groundwater Management Area (GMA). These districts must jointly
agree upon and establish the desired future conditions (DFC) of the aquifers
within their respective GMAs. Through this process, the districts will submit
the DFC conditions to the executive administrator of the Texas Water Development
Board (TWDB), who will provide each district in the GMA with the amount of
Managed Available Groundwater (MAG) for each district. The MAG will be based on
the desired future conditions jointly established for each aquifer within the
respective GMA divisions.
Technical information, such as the desired
conditions of the aquifers within the District's jurisdiction and the amount of
managed available groundwater from such aquifers is required by statute to be
included in the District's management plan and will guide the District's
regulatory and management policies. This management plan is intended to satisfy
the requirements of SB 1, SB 2, HB 1763, the statutory requirements of Texas
Water Code (TWC) Chapter 36, and the rules and requirements of the TWDB.
III.-A FORMATION AND AUTHORITY
The District was created by the citizens of
The boundaries of the Pecan
Valley Groundwater Conservation District (PVGCD) are coterminous with those of
Figure 1: Pecan Valley Groundwater Conservation
District Boundaries
The district lies in the West Gulf Coastal Plain of
South-Central Texas, spans 910 square miles and is mostly rural. The population of the district according to
the most recent census is estimated to be close to 20,500 and is expected to
grow due to its proximity to urban centers such as
The land surface of the

Figure 2: Topography of the
DeWitt county, (and as such
PVGCD) is mostly rural and the economy is dominated by agriculture, livestock
management, tourism, oil and gas as well as other mining operations. There is also some light industrial activity
within the district. (Uddameri,
2008)
Figure 3: Land Use Characteristics within Pecan
Valley Groundwater Conservation District
As can be seen from Figure 3,
croplands and pastures are dominant in the northwestern sections of the
county. (Uddameri, 2008)
The surface soils of the district
are dominated by sandy loams (see Figure 4)

Figure 4: Surface Soil Textural
Characteristics in PVGCD (Based on USDA STATSGO data)
The district is
overlain by sandy clay loam along the western boundaries and loamy fine sands
in the central portions of the district.
These surface soil characteristics coupled with scant rainfall indicate
that recharge to the underlying aquifers may not be significant. (Uddameri, 2008)
The deeper aquifer formations
within the district are from the Tertiary era while the shallower formations
are from the more recent Quaternary age.
The major stratigraphic units include the Lissie formation, Goliad
sands,

From a regional stratigraphic
standpoint, the major aquifers in the district include the Gulf Coast Aquifer
and the Carrizo Wilcox Aquifer. While the Carrizo Wilcox aquifer does not
outcrop within the district, it is present underneath the Gulf Coast Aquifer. (Uddameri, 2008)

Figure 5: Major Aquifer Formations within
the District
The Gulf Coast Aquifer is known
to comprise four aquifer formations, namely – Chicot, Evangeline, Burkeville
confining layer and the Jasper formation.
The

Figure 6: Chicot Aquifer Formation of the
The Chicot formation outcrops along
the South Eastern sections of the district.
It occupies a very small portion of the district and not very prolific
as such has limited use. (Uddameri, 2008)

Figure 7: Evangeline Aquifer Formation of
the
The Evangeline aquifer formation
extends along the eastern sections of the district and can be found until
roughly the middle of the district. The
formation is unconfined for the most part, except when the Chicot formation is
present. Sections of this formation are
also referred to as Goliad sands and represent some of the more prolific
aquifer formations within the district. (Uddameri, 2008)

Figure 8: Burkeville Confining Layer
(with usage shown in Blue)
The Burkeville confining layer
outcrops in the middle sections of the district. The layer is mostly comprised of clays
(sometimes locally referred to as Lagarto clays) and as such not very prolific. (Uddameri, 2008)

Figure 9: Jasper Aquifer Formation (with
usage shown in blue)
The Jasper aquifer formation
outcrops along the western sections of the district, but exists under confining
conditions over the entire district. The
aquifer is used extensively in the western portions where it is shallower and
especially when Evangeline formation is absent.
Some of the municipal wells are also located in this formation.
The Carrizo Wilcox aquifer is
often envisioned to comprise of

VI. STATEMENT OF GUIDING
PRINCIPLES
The District
recognizes the vital importance of this valuable resource to all water users.
The District considers all landowners to be partners with the District in the
effort to protect, preserve and conserve groundwater, and to prevent waste, and
recognizes landowners as the primary stewards of the groundwater resources
associated with their properties. The
District will work with these partners to achieve these goals for the benefit
of all water users, the local economy, and the environment.
The purposes of the District are achieved through
research and education programs, district-provided services, mutual cooperation
of local, state, and federal agencies, mutual cooperation with non-governmental
entities, and management as provided by
The
District has adopted, pursuant to TWC Chapter 36 and the provisions of this
plan, rules,
programs and procedures to manage groundwater withdrawals while protecting the
socio-economic conditions within the District. The District’s Board may
consider, deliberate and weigh any factor, evidence or testimony before it that
it deems necessary in making any findings and revisions to this groundwater
management plan, or the District’s Rules. In doing so, the District’s Board may
consider the following criteria:
(i) any revision
based on sound science;
(ii) any
socio-economic impact reasonably expected to occur;
(iii) any
environmental impacts;
(iv) State policy
and legislative directives; and
(v) any other
information relevant to a specific condition.
The
District will continue to work in cooperation with the adjacent districts to
manage and protect those groundwater resources that are shared by any or all of
these counties. The District will
provide public awareness and education of groundwater issues, and will stay
informed of the activities of the Texas Legislature, Texas Water Planning
Groups, along with the rules and orders of state agencies which may affect
private ownership, use, and management of groundwater.

VIII-A Managed
available groundwater in the district based on the Desired Future
Condition established under TWC 36.108—TWC §
36.1071(e)(3)(A)
.Estimates of the managed available groundwater is obtained through
the Groundwater Management Area (GMA) joint planning process. Pecan Valley Groundwater Conservation
District is part of the GMA 15 which is currently in the process of developing
desired future conditions that will lead to the quantitative estimates of managed
available groundwater (MAG) that will be developed by the Texas Water
Development Board. As such, estimates
for MAG for the district are currently unavailable. Estimates previously developed by the
Regional Water Planning Group (Region L) and judgments based on regional
hydrogeologic characteristics indicate that the available groundwater to be
around 10,000 – 15,000 ac-ft/yr (Uddameri, 2008)
VIII-B Annual
Use – 31 TAC 356.5(a)(5)(B) (Implementing TWC §36.1071(e)(3)(B))
The historical groundwater usage
in the district was obtained from Texas Water Development Board Water Use
Database and summarized below. As can be
seen, the groundwater use within the district is fairly steady at around 3,250
AFY. It can also be seen that
groundwater is the dominant source of water within the district. (Uddameri, 2008)

Generally speaking, recharge
exhibits considerable variability due to a variety of factors including erratic
rainfall, soil moisture characteristics and modifications to land use. (Uddameri 2008)

of Groundwater Discharge to springs and Surface Water Bodies – TWC §36.1071(e)(3)(D)
One of the major surface water
bodies in the district is the

In general, while the aquifer may
gain or lose water at different sections of the district, there is a net
discharge from the aquifers into the surface water bodies. The interaction with surface water bodies is
the highest for the Evangeline formation (which is the dominant outcrop aquifer
within the district). (Uddameri, 2008)
VIII-E Estimate
of Annual Volume of Flow In and Out of District Aquifers §36.1071(e)(3)E)
The horizontal exchanges (lateral movement of water
across the district boundaries) were calculated over time using GAM models and
summarized in Table 5. As can be seen, there is net
outflow out of the Gulf Coast Aquifer units and there is a net inflow into the
district in the Carrizo Wilcox formation.
As can be seen from Table 5, Chicot and Evangeline formations have the
greatest exchanges in the

Deviations and fluctuations can be expected
based on the hydrologic characteristics, groundwater development within the
district and adjoining areas, and changing climatic conditions. Movement of water between formations depends
on how well they are hydraulically connected.
Movement is also affected by the stresses (pumpage) in each
formation.

The projected demand was obtained from the most
recent state water plan from the Texas Water Development Board (TWBD) DB07
Database (http://www.twdb.state.tx.us/data/db07/defaultReadOnly.asp).
These results are summarized below and indicate
that it is going to stay steady at roughly 5,000 AFY. However, recently there has been considerable
interest in oil and gas exploration as well as mining activities. These activities may increase the water
demand within the district. (Uddameri, 2008)

VIII-I Consider
The Water Supply Needs and Water Management Strategies included in the adopted
State Water Plan – TWC §36.1071(e)(4)
In the 2007 State Water Plan there are no
unmet water needs in the Pecan Valley GCD and no projected water
shortages. The 2007 State Water Plan
recommended municipal water conservation measures.
Although the implementation time-frame for
these strategies fall outside the planning horizons of this management plan,
the district strongly encourages the recommended conservation measures and will
seek to actively understand the role of surface-water groundwater interactions.
IX. DISTRICT MANAGEMENT OF GROUNDWATER SUPPLIES
The Texas Legislature established that groundwater
conservation districts are the preferred method of groundwater management in
Section 36.0015 of the Texas Water Code. The District will manage the use of groundwater
within the District in order to protect, preserve, conserve, and prevent waste
of the resource while seeking to maintain the economic viability of all
resource user groups, public and private. The District seeks to manage the
groundwater resources of the District as practicably as possible as established
in the plan. In consideration of the economic and cultural activities occurring
within the District, the District will identify and engage in such activities
and practices, that if implemented may result in the reasonable and effective
protection, preservation, conservation, and waste prevention of groundwater in
the District. The District will manage
groundwater resources through rules developed and implemented in accordance
with Chapter 36 of the Texas Water Code and the provisions of the District Act.
For the purposes of this management plan, the following definitions are used:
or injury to a groundwater
resource.
useful longevity or life of a
groundwater resource.
groundwater resource in a manner
that appropriately balances the impacts
associated with consuming a
resource and preserving a resource.
the use of groundwater in any
manner defined as waste in Section 36.001 of the
A
network of observation wells will be established and maintained in cooperation
with private landowners in order to monitor changing water levels and water
quality of groundwater supplies within the District. The District will make
regular assessments of water supply and will
report those conditions to the public. The District will undertake and
cooperate with investigations of the groundwater resources within the District
and will make the results of investigations available to the public.
For the purpose of managing the use of groundwater
within the District, the District may define sustainable use as the use of an
amount of groundwater in the District as a whole or any management zone
established by the District that does not exceed:
1. The desired future conditions of aquifers in the District
established by the District
prior
to the establishment of the desired future condition of aquifers in a
groundwater
management area in which the District is located, or
2. The desired future conditions of aquifers within the District
established by a
groundwater
management area in which the District is participating, or
3. The amount of managed available groundwater resulting from the
establishment
of
a desired future aquifer condition established by the District or a groundwater
management
area in which the District is located, or
4. The amount of annual recharge of the aquifer or aquifer
subdivision in which the
use
occurs as recognized by the District, or
5 Any other criteria established by the District as being a
threshold of use beyond
which
further use of the aquifer or aquifer subdivision may result in a specified
undesirable
or injurious condition
The District may adopt rules that protect existing
or historic use of groundwater in the District to the maximum extent practical
consistent with this plan and the goals and objectives set forth herein. The
District may impose more restrictive permit conditions on new permit
applications and permit amendment applications to increase use by historic
users if the limitations:
1. Apply to all subsequent new permit
applications and permit amendment applications to increase use by historic
users, regardless of the type or location of use;
2. Bear a reasonable relationship to the District's
existing management plan; and
3. Are
reasonably necessary to protect existing use
4. The District may adopt rules to regulate
groundwater withdrawals by means of spacing and/or production limits. The
relevant factors to be considered in making a determination to grant or deny a
permit or limit groundwater withdrawals shall include those set forth in the
District Act, Chapter 36 of the Texas Water Code, and the rules of the
District. The District may employ technical resources at its disposal, as needed,
to evaluate the groundwater resources available within the District and to
determine the effectiveness of regulatory or conservation measures. In
consideration of particular individual, localized or District-wide conditions,
including without limitation climatic conditions, the District may by rule
allow an increase or impose a decrease in the total production in a management
zone above or below the sustainable amount for a period of time considered
necessary by the District in order to accomplish the purposes set forth in Chapter
36 Water Code, or the District Act. The exercise of said discretion by the
Board shall not be construed as limiting the power of the Board.

XI METHODOLOGY FOR TRACKING DISTRICT PROGRESS IN
The
General Manager of the District (or, in the absence of a General Manager, the
Chairman of the Board) will prepare and present an annual report to the Board
of Directors (Annual Report) evaluating the impact of the District’s activities
on its goals, management objectives, and performance standards (as enumerated
below). The Annual Report will be presented 120 days following the completion
of the District’s fiscal year. The Annual Report will include the number of
instances that each activity of the District occurred during the year (such as
the monitoring of wells for water quality and levels, permitting, inspecting
for permit compliance, securing abandoned wells), together with an estimate of
the expenditure of staff time and cost so that the effectiveness and efficiency
of each activity may be evaluated.
The
annual District Manager’s Report will be received by the District Board and
upon approval shall be available to the public at the District Office. The Board of Directors will meet at least
quarterly to review all considerations by the District to fully comply with all
rules and regulations set forth by the Texas Water Development Board.
