​The Comal Trinity Groundwater Conservation District (CTGCD) was created to help Comal County residents conserve, preserve, recharge, protect, and prevent waste of groundwater from the Trinity Aquifer which underlies all of Comal County.  The Comal Trinity GCD was created during  the 2015 84th Texas Legislature with the enrollment of House Bill 2407 and became effective 17 June 2015. The bill provides the GCD the authority to issue bonds; and impose assessments, fees, or surcharges.
