What is the current level of the San Antonio aquifer?
Water level data are critical for EAA’s management of the San Antonio Pool and the Uvalde Pool of the Edwards Aquifer. Water levels are measured around the clock using different devices in monitoring wells throughout the aquifer….Today’s Current Readings.

How deep is the aquifer in San Antonio?
The story of water and Texas starts here, some 650 feet below the surface, in San Antonio. That’s the historic average for October of the J-17 well, 658 feet above sea level, the measure that influences everything related to the Edwards Aquifer. The Edwards is one of the most abundant artesian aquifers in the world.
What is normal level for Edwards Aquifer?
Stage 2 restrictions begin when the 10-day rolling average of the Edwards Aquifer level reaches 650 feet mean sea level at the monitored well. Coming out of drought stages can be considered 15 days after the aquifer is above the trigger.
How deep is the Edwards Aquifer?
about 300 to 700 feet
The effective porosity, or the amount of water that is capable of being recovered, of the Edwards aquifer is estimated to be about 5%. The aquifer ranges in thickness from about 300 to 700 feet (100 – 200 meters).
What is Edwards Aquifer recharge zone?
Recharge Zone The part of the Edwards Aquifer with sinkholes and fractures where rainwater easily enters and refills the aquifer.
Is the Edwards Aquifer unconfined?
The large porosity and exceptional permeability of the unconfined part of the Edwards aquifer result from the dissolution of limestone by circulating ground water and development of a cavernous network along fractures.
What is the highest level of the Edwards Aquifer?
The land surface at the top of the J-17 well is at 730.8 feet above sea level, and the downtown area around the Tower of the Americas is around 650 feet above sea level. A reported Aquifer level of 650 feet, for example, would indicate the top of water in the well is about even with the bottom of the Tower.
What pollutes Edwards Aquifer?
Despite the immeasureable value of this natural resource, human activity – urbanization – now threatens to taint the water of the Edwards Aquifer with a slew of pollutants – from fertilizers and pesticides to toxic metals and sewage spills.
Who has regulatory authority over water from the Edwards Aquifer in Texas?
The EAA is governed by a 17-member board of directors representing the interests of constituents from across the Edwards Aquifer region. The EAA, a member of the Texas Water Development Board Region L Planning Group, also collaborates with other groundwater districts and related stakeholder groups.
What is the Edwards Aquifer artesian zone?
The artesian zone of the Edwards is confined between two relatively impermeable formations – the Glen Rose formation below and the Del Rio clay on top. The sheer weight of new water entering the Aquifer in the recharge zone puts tremendous pressure on water that is already deeper down in the formation.
