EAA imposes pumping restrictions across region


Contact: Roland Ruiz with the EAA, (210) 477-5143 or mobile, (210) 416-6116; and HTGCD general manager Rick Broun at (512) 858-9253.

Note: Mr. Ruiz says readings taken from EAA's main monitoring well, the J17, show a drop of about 19 feet from the beginning of April and dropping about a foot a day."There hasn't been any rain and what made things a little bit more difficult is the seasonal irrigation demand came in (from farmers)," Ruiz said. Rick Broun, the general manager of the Hays Trinity Groundwater Conservation District, says the district remains in "voluntary conservation" in western Hays County. Pumping restrictions are put in place for permitted users based on low flows in the Blanco and Pedernales Rivers. "I look at it (water flow readings) every day," Broun told the RoundUp. "It's headed that way (declining) but we're not close yet," Broun said.



SAN ANTONIO (May 3, 2012) – The Edwards Aquifer Authority (EAA) today declared Stage II mandatory pumping reductions for Edwards Aquifer users within its San Antonio Pool, which means more significant limits on how much water can be pumped from the aquifer. Stage II of the EAA critical period management plan requires Edwards groundwater permit holders in the San Antonio Pool – including all of Bexar and Medina, and parts of Atascosa, Caldwell, Comal, Guadalupe and Hays counties – to reduce their pumping from the aquifer by 30 percent of their annual authorized amount. (The cities of San Marcos and Kyle rely on groundwater from the Edwards for a portion of their local water supply and are subject to the mandatory reduction.)

Edwards Underground Aquifer
The EAA declared Stage II based on declining water level readings at the J17 index well in Bexar County. The 10-day rolling average water level reading at the well dropped below the Stage II threshold on May 3, 2012. Stage II will remain in effect as long as the J17 index well level remains below the Stage II, but above the Stage III trigger threshold. A drop in the rate of discharge below the respective Stage II thresholds for the Comal or San Marcos springs would also keep the region under Stage II restrictions. The San Antonio Pool previously had been under Stage I since April 18, 2012.
