Regional Water Planning Groups

In June 1997, Governor George W. Bush signed into law Senate Bill 1 (SB 1), comprehensive water legislation enacted by the 75th Texas Legislature. This legislation was an outgrowth of increased awareness of the vulnerability of Texas to drought and to the limits of existing water supplies to meet increasing demands as population grows. The state's population is expected to increase from its current level of about 19 million to more than 39 million people by the year 2050.

With passage of SB 1, the Legislature put in place a "bottom up" water planning process designed to ensure that the water needs of all Texans are met as Texas enters the 21st century. SB 1 allows individuals representing 11 interest groups to serve as members of Regional Water Planning Groups (RWPGs) to prepare regional water plans for their respective areas. These plans will map out how to conserve water supplies, meet future water supply needs and respond to future droughts in the planning areas.

Fayette County belongs to the Lower Colorado Regional Water Planning Group (Region K).

Groundwater Management Areas (GMAs)

Chapter 35, §35.004 of the Texas Water Code required the Texas Water Development Board, with assistance from the Texas Commission on Environmental Quality (TCEQ), to designate GMAs covering all major and minor aquifers in the state.  The initial designation was to be completed by September 1, 2003 .  The statute provided that each GMA shall be designated with the objective of providing the most suitable area for the management of groundwater resources. The GMAs so designated, shall, to the extent feasible, coincide with the boundaries of a groundwater reservoir or subdivision of a groundwater reservoir (aquifer).  

Fayette County is included in two different GMAs, GMA 12 and GMA 15.
