The aquifer drops below 640' for the first time in more than 7 years. Stage 3 restrictions are ahead for permit holders.

The 10-day rolling average of the Edwards Aquifer has dipped below 650 feet, prompting Stage 2 water restrictions

Heavy rain overnight resulted in rainfall totals of 1-3", with higher isolated totals.

The Edwards Aquifer Research Park is a more than 150-acre tract of land that will be used to study the aquifer.

SAN ANTONIO – Data from NASA satellites show high concentrations of carbon monoxide in the atmosphere as a result of this year’s wildfires on the west coast. Carbon monoxide, emitted during a combustion event - like a fire - can increase concentrations of greenhouse gases in the Earth’s atmosphere. These greenhouse gases, like carbon dioxide and methane, have been linked to an increased global temperature. Of course, this increasing global temperature is one of the major facets of the climate change battle our Earth is facing. Let us know what climate questions you have in the prompt below.

Today, this vast system of “holey” limestone around South Central Texas is called the Edwards Aquifer.

SAN ANTONIO – Edwards Aquifer levels saw a sharp decline in the month of April and continue to fall after a long period of healthy numbers. As of Monday, the J-17 well of the Edwards Aquifer sat at 664.3 feet. Why is the aquifer level falling? According to San Antonio Water System, Stage 1 restrictions begin when the 10-day rolling average of the Edwards Aquifer level drops to 660 feet mean sea level at the monitored well (J-17). Where can you find the latest aquifer level?
