Underground Water Conservation District, Guadalupe County Groundwater Conservation District,

Creek Conservation District, Uvalde County Underground Water Conservation District, Wintergarden
Groundwater Conservation District; GMA-13 considered and adopted the following Proposed Desired
Future Conditions (DFCs) for GMA-13 regional groundwater planning purposes:
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 atthe end of 2012 remains in 2070. This desired future condition is considered feasible despite
model predictions to the contrary as detailed in GMA 13 Technical Memorandum 16-08.

In addition, a secondary proposed desired future condition for the Carrizo-Wilcox/QueenCity/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 TechnicalMemorandum 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, the average drawdown from 2010 to 2070 is 3 feet, for Karnes County, theaverage drawdown from 2010 to 2070 is 1 foot, and for all other counties in GMA 13, the YeguaJackson 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 inGMA 13 for purposes of joint planning.
