The Edwards Aquifer Authority handles Edwards Aquifer wells within its jurisdiction, the Comal Trinity Groundwater Conservation District sets rules for Trinity aquifer borings in Comal County, and the Guadalupe-Blanco River Authority manages Canyon Reservoir's stored water.
Start by identifying whether your question concerns an Edwards well, a Trinity well or boring, or water stored in the reservoir. The agencies describe different responsibilities on their Edwards Aquifer Authority regulatory page, Comal Trinity district page and GBRA reservoir page.
From the source record
All BORINGS into the Trinity group of aquifers in Comal county must be done in accordance with Rules discussed in public hearings and adopted by the Board.Comal Trinity Groundwater Conservation District ↗
A Comal County resident's starting point for a well permit or drought question depends on the water source and the property's jurisdiction; Canyon Reservoir's flood-control pool is managed separately by the U.S. Army Corps of Engineers. A reservoir question can also require distinguishing stored water from flood control. The table shows what each agency says it handles and where to begin.
