aquifer and to limit pumping to protect the spring flow levels. In 1997, Chapter 36 of the Texas Water Code was amended by Senate Bill 1 of the 75th Texas Legislature to require all underground water conservation districts in Texas to develop a groundwater management plan and submit it for approval by the Texas Water Development Board every five years on the anniversary of initial approval (September 17, 1998 for the Edwards Aquifer Authority). The initial requirements of the groundwater management plans were that they address the efficient use of groundwater, methods of controlling and preventing waste of groundwater, conjunctive surface water issues, natural resource issues that affect the use and availability, of groundwater, and methods of controlling and preventing subsidence. The requirements of groundwater management plans have since undergone expansion to require the inclusion of planning requirements for addressing drought conditions and conservation (2001, the 77th Texas Legislature Senate Bill 2), estimates of the managed available groundwater, the amount of groundwater used within each district, the amount of recharge from precipitation, projected surface water supply, total water demand within the district, and consideration of water management strategies that were included in the adopted state water plan (2005, 79th Texas Legislature HB 1763). Senate Bill 2 of the 77th Texas Legislature also required the groundwater conservation districts to submit groundwater management plans to the Chair of any Regional Water Planning Group in which any part of the district is located so that they may specify any area(s) that conflict with the approved Regional Water Plan[1]. In addition to the groundwater management plan, the Edwards Aquifer Authority board of directors maintains a three-year rolling strategic plan that is updated annually. The 2015-2017 strategic plan adopted on October 14, 2014 identifies six major goals: Goal A: Sustain Federally Protected Aquifer-Dependent Species Goal B: Ensure Effective Management of the Edwards Aquifer Goal C: Enhance Recharge Program for Improved Aquifer Management and Springflow Maintenance, Goal D: Prevent the Pollution of the Aquifer Goal E: Conduct Research that Enhances Understanding and Effective Management of the Aquifer Goal F: Develop a Diverse, Service-Oriented Organization Goal G: Build Shared Value in the EAA Mission Goal H: Sustain Fiscal Stability [3] With the growth of regional cities such as San Antonio, municipal demand for water increased. The second half of the twentieth century saw a high volume of legal activity regarding rights to the aquifer. Water balance Although
