APPENDIX EThe tables presented in this appendix are taken from the Gonzales County UndergroundWater Conservation District Management Plan and the Rules of the Gonzales CountyUnderground Water Conservation District. They are presented to provide additionalinformation on the conditions of the aquifers that provide groundwater to CaldwellCounty. Tables are listed as they are presented.Gonzales County Underground Water Conservation District Management PlanTABLE 5GROUNDWATER RECHARGE/ DISCHARGE/ FLOW GONZALES ANDCALDWELL COUNTIESAquifer orConfining UnitGroundwater Recharge/Discharge/FlowGonzales and Caldwell CountiesGonzales County Underground Water Conservation DistrictAnnual RechargefromPrecipitation(acre-feet/yr)Annual Dischargefrom Aquifer toSurface Water(acre-feet/yr)Annual FlowInto District(acre-feet/yr)Annual FlowOut ofDistrict (acrefeet/yr)Sparta 3,105 2,127 386 70Weches 808 521 117 35Queen City 7,291 3,583 1,172 126Reklaw 2,168 1,935 170 156Carrizo 6,927 6,896 8,897 5,732Wilcox (upper) 0 0 30 48Wilcox (middle) 921 31 2,031 3,488Wilcox (lower) 0 0 4,052 2,506Data from GAM 08-22 RevisedTable 5 describes the following as listed in the GCUWCD:1. Precipitation Recharge – this is the aerially distributed recharge sourced fromprecipitation falling on the outcrop areas of the aquifers (where the aquifer isexposed at the land surface) within the District.2. Surface Water Outflow – this is the total water existing the aquifer (outflow) tosurface water features such as streams, reservoirs, and drains (springs).3. Flow Into and Out of District – this component describes lateral flow within theaquifer between the districts and adjacent counties.
