Improved Aquifer Conditions in Uvalde, TX Result in End of Critical Period Management for the Uvalde Pool
San Antonio, TX – The Edwards Aquifer Authority (EAA) has lifted all Critical Period Management (CPM) pumping curtailments for Edwards withdrawal permit holders in the Uvalde Pool ...of the EAA’s jurisdiction (Uvalde County) effective, Tuesday, August 11, 2026. The EAA declared the lifting of CPM based on improved aquifer conditions as the 10-day average at the J-27 index well measured 850 feet above mean sea level (ft. amsl), which is above the threshold for all stage restrictions within the Uvalde Pool. The Uvalde Pool has been under a stage of CPM reductions since June 2022 due to prolonged drought. However, significant rainfall across much of the region in July has caused the Uvalde Pool to trend upward over the past few weeks.
The EAA is a groundwater conservation district that manages, enhances, and protects the Edwards Aquifer, a major groundwater system serving approximately two-and-one-half million South Central Texans. The EAA jurisdiction spans across 8 counties including Uvalde, Medina, Bexar, and parts of Atascosa, Caldwell, Guadalupe, Comal and Hays counties.
