The Trinity Glen Rose Groundwater Conservation District was created by HB 2005 during the 77thTexas Legislature. HB 2005 was authored by State Representatives Frank Corte Jr. and John Shields and sponsored by Senator Jeff Wentworth. The bill was signed into law and took effect on September 1, 2001 and confirmed by voters in 2002.  The District was created as a result of the Texas Commission on Environmental Quality (TCEQ) designating the Trinity group of aquifers lying within northern Bexar County as a Priority Groundwater Management Area (PGMA). 


In 2009, the 81st Texas Legislature passed HB1518 allowing an increase of production fees and allowing municipalities to request inclusion of annexed areas into the District as provided by Chapter 36 Texas Water Code.


The mission of the District is to provide rules and regulations to manage, conserve, preserve, protect, maximize recharge and prevent waste of the water resources within the section of the Trinity Aquifer located in northern Bexar County.
