90-Day Public Comment Period
Proposed Desired Future Conditions
Dear Interested Member of the Public:
On April 27, 2016, the Groundwater Management Area 13 Joint Planning Committee (GMA-13) adopted
proposed Desired Future Conditions (DFCs) for the Carrizo-Wilcox, Queen City, Sparta, and Yegua-Jackson
Aquifers within the management area. In addition, GMA-13 has classified certain aquifers or portions of thoseaquifers as non-relevant for the purposes of joint planning. A summary of these proposals and relevant aquifer
designations follows:

The first proposed desired future condition for the Carrizo-Wilcox/Queen City/Sparta Aquifers in
Groundwater Management Area 13 is that 75 percent of the saturated thickness in the outcrop at the endof 2012 remains in 2070. This desired future condition is considered feasible despite model predictions tothe contrary as detailed in GMA 13 Technical Memorandum 16-08.



In addition, a secondary proposed desired future condition for the Carrizo-Wilcox/Queen City/Sparta
Aquifers in Groundwater Management Area 13 is an average drawdown of 48 feet for all of GMA 13.
The drawdown is calculated from the end of 2012 conditions to the year 2070. This desired future
condition is consistent with Scenario 9 as detailed in GMA 13 Technical Memorandum 16-01 and GMA
13 Technical Memorandum 16-08.

The proposed desired future conditions for the Yegua-Jackson Aquifer in Groundwater Management Area
13 are summarized in GMA 13 Technical Memorandum 16-04 (Draft 1). For Gonzales County, theaverage drawdown from 2010 to 2070 is 3 feet, for Karnes County, the average drawdown from 2010 to2070 is 1 foot, and for all other counties in GMA 13, the Yegua-Jackson is classified as not relevant for
purposes of joint planning.



The Trinity, Edwards, and Gulf Coast Aquifers are designated as non-relevant for all counties in GMA 13
for purposes of joint planning.

On Monday, May 2, 2016, notice of these proposals was sent to each of the nine Groundwater Conservation
Districts (GCDs) within GMA-13. Therefore, the official 90-day public comment period related to the proposed
DFCs began on Monday, May 2, 2016, and will close on Monday, August 1, 2016. Public comments can besubmitted directly to your local GCD at any time before the 90-day public comment closes. Also, each GCD willhold a public hearing regarding the proposed DFCs related to that GCD, as may be applicable. To find out thetime, date and location for your local GCD’s public hearing, please contact them directly as follows:
To help the GCDs give your comments their due consideration, GMA-13 is providing this public comment
form for your use in preparing and submitting comments during the 90-day public comment period. Every
section of this public comment form reflects factors the GCDs must consider and document as we make these
DFC decisions. To that end, we encourage you to complete as much of the public comment form as possible.
You may also attach additional pages, if necessary. Please note, in accordance with Subsection 36.108 (d-2) of
the Texas Water Code, the GCDs will only consider public comments that are determined to be relevant.
Completed public comment forms should be submitted to directly to your local GCD at the contact information
listed above. Copies of your completed public comment forms, along with any other relevant public comments

received during the 90-day public comment period, will be reviewed by your local GCD and will be reflected
as part of the public comment summaries each GCD will prepare and submit to GMA-13.
Thank you for taking time to participate in this very important process. If you have any questions, please contact
your local GCD representative at the contact information provided above.

Proposed Desired Future Condition(s)Please be as detailed as possible in describing your proposed DFC. Include the quantifiable value and a
description of the method for measuring or calculating the value. Please attach additional pages, if needed.

Proposed DFC and Measuring/Calculating Method

Consideration of Proposed Desired Future Condition(s)The Texas Water Code requires that GMA-13 develop DFCs that “provide a balance between the highest
practicable level of groundwater production and the conservation, preservation, protection, recharging, andprevention of waste of groundwater and control of subsidence in the management area.” In the space below, or on
additional attached pages, please provide your considerations with regard to the nine items that must be
considered, per the Texas Water Code, for the proposed DFC(s).
Consideration 1 – “Aquifer uses or conditions within the management area, including conditions that differ
substantially from one geographic area to another:” _______________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________

Consideration 2 – “The water supply needs and water management strategies included in the state waterplan:” _____________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________
Consideration 3 – “Hydrological conditions, including for each aquifer in the management area the total
estimated recoverable storage as provided by the executive administrator, and the average annual
recharge, inflows, and discharge:” _____________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________
Consideration 4 – “Other environmental impacts, including impacts on spring flow and other interactions
