Aquifer authority declares Stage 4

San Antonio — The Edwards Aquifer Authority (EAA) on Tuesday declared Stage 4 pumping reductions for users within the San Antonio Pool. Stage 4 of the EAA’s drought plan requires Edwards groundwater permit holders in all of Bexar and Medina, and parts of Atascosa, Caldwell, Comal, Guadalupe and Hays counties to reduce their annual authorized pumping by 40 percent.
The EAA declared Stage 4 based on declining water level readings at the J17 index well in Bexar County. On Tuesday, it was officially confirmed that the 10-day average dropped below the Stage 4 threshold of 630 feet above sea level. Stage 4 will remain in effect as long as the water level of the monitoring well stays below this threshold.
The purpose of mandatory pumping reductions is to stabilize aquifer levels and spring flow until rainfall replenishes the aquifer. Stage 4 reductions apply to all Edwards groundwater permit holders authorized to pump more than three acre-feet annually. All affected permit holders must also report their pumping totals to the EAA on a monthly basis.
Residents and businesses who receive their water from a public water system are encouraged to contact their water provider directly to find out how Stage 4 reductions may affect them. More information on Stage 4 requirements is available by calling the EAA Critical Period Team at (866) 931-3239 or by visiting the EAA website at www.edwardsaquifer.org.
The Edwards Aquifer Authority manages, enhances, and protects the Edwards Aquifer, a major groundwater system serving approximately 2 million South Central Texans.
