Edwards Aquifer Drops to Stage 3: What San Antonio Homeowners Need to Know Right Now

If you have a lawn sprinkler system, a pool, or an irrigation permit tied to the Edwards Aquifer, pay attention. The Edwards Aquifer Authority announced this week that Stage 4 drought restrictions, in place since August 2025, are being lifted. Permit holders are now operating under Stage 3, which requires a 35% cut in pumping rather than the previous 40% cut. That five-percentage-point difference is modest, but after nearly ten months under the tighter rules, it offers a real, if cautious, bit of relief.

The decision is driven by two key measurements. The J-17 index well, located in the Leon Valley area and considered the primary gauge of aquifer health, was reading a 10-day average of 632.7 feet as of this week. Comal Springs in New Braunfels was flowing at 100 cubic feet per second. Together, those numbers pushed the aquifer just above the 630-foot threshold that triggers Stage 4 and just below the 640-foot level that would allow a return to Stage 2.

To put that in plain terms: the aquifer is better than it was, but it is not healthy. At 632.7 feet, the J-17 average sits only 2.7 feet above the line that would send restrictions back to Stage 4, and 7.3 feet below the line that would ease them further. Stage 5 kicks in at 625 feet. We are in a narrow band during what is typically the driest stretch of the year in Central Texas, with the peak of summer still ahead.

For homeowners across San Antonio and the surrounding communities, here is what this means in practical terms.

If you have an irrigation permit or your HOA manages common-area landscaping on permit water in areas like Stone Oak, Alamo Ranch, Helotes, Boerne, Schertz, or Cibolo, your allowed pumping volume increases slightly under Stage 3. That does not mean it is time to run your sprinklers freely. Stage 3 still requires significant conservation, and the aquifer's position this week means conditions could change quickly if summer heat sets in hard without meaningful rain.

For homeowners in the city of San Antonio served by San Antonio Water System, your water utility has its own drought response plan that is tied to EAA restrictions but is administered separately. Check directly with SAWS for any updates to your watering schedule or day restrictions, since utility rules and EAA permit rules are not always identical.

If you are buying a home, this is a good moment to ask detailed questions about outdoor water use. Properties in the Hill Country fringe communities like Helotes, Leon Valley, Grey Forest, and unincorporated Bexar County sometimes rely more directly on well water tied to the aquifer. Understanding how drought stages affect a property's water supply and landscaping costs should be part of your due diligence before closing.

For sellers, the current status is actually a small positive talking point relative to where things stood last fall, but experienced buyers will want to know the history. If your home sat through Stage 4 restrictions and the lawn or landscaping shows stress, be prepared to address that honestly. A well-maintained yard that survived Stage 4 is a genuine selling point in this market.

Renters, particularly those in single-family homes where water and landscaping upkeep may be the tenant's responsibility, should confirm in writing with their landlord or property manager what watering restrictions apply to the property and who is responsible for keeping the yard within compliance. Violating EAA or SAWS restrictions can result in fines, and clarity upfront protects everyone.

For homeowners who invested in drought-tolerant landscaping, smart irrigation controllers, or rainwater harvesting systems over the past few years, the current situation is a reminder that those upgrades pay off in more ways than one. Homes in neighborhoods like Shavano Park, Hollywood Park, and Terrell Hills with established native plantings consistently cost less to maintain through drought restrictions and tend to hold their curb appeal better when watering windows are limited.

The broader takeaway is this: the aquifer is moving in the right direction, slowly, and that is good news. But with the J-17 index sitting in a tight range and summer just beginning, now is not the time to ease up on conservation habits. Whether you are a homeowner watering a vegetable garden in Converse, a landlord managing properties near the UTSA corridor, or a buyer touring homes in the Northside or Judson school districts, understanding where your water comes from and how restrictions affect daily life is increasingly part of owning or occupying a home in San Antonio.

Keep an eye on the EAA website for J-17 updates, which are posted regularly. The stage designation can change whenever the 10-day average crosses a trigger point, and summer conditions in South Texas can move those numbers fast in either direction.
