TRINITY AQUIFER EDUCATION Learning About the Trinity Aquifer The Trinity Aquifer is one of nine major aquifers defined by the state , stretching from the Texas Hill Country into Oklahoma, and it is the primary water source within the Trinity Glen Rose Groundwater Conservation District (TGR). Pecos Valley Seymore Gulf Coast Carrizo-Wilcox Outcrop Carrizo-Wilcox Subgroup Hueco-Mesilla Bolsons Ogallala Edwards-Trinity Outcrop Edwards Outcrop Trinity Outcrop Trinity Subcrop Edwards Subcrop Edwards-Trinity Subcrop Trinity Aquifer in Northern Bexar County Edwards Aquifer Region in Blue Though often referred to as a single aquifer, the Trinity Aquifer is really a group of aquifers , experts say. It’s divided into three units — the Upper, Middle and Lower Trinity — and within those are more layers, or strata, made up of different formations, all of which allow water to move through in different ways and at different rates. The Trinity system stretches across 61 counties from northeast of Dallas to southwest of San Antonio covering more than 10,000 square miles at the surface and more than 21,000 square miles below ground. It runs throughout much of the Hill Country, including all or portions of Kendall, Comal, Hays and Blanco counties, and is considered one of the “most extensive and highly used groundwater resources in Texas” by the Texas Water Development Board. The Trinity Aquifer is a low production aquifer which recharges slowly, with only 4–5% of rain recharging it. Despite its slow recharge rate, it stands as one of Texas’ most extensive and heavily used groundwater resources. Primarily utilized by municipalities, it also serves as a vital source for rural homes, irrigation, livestock, and other domestic uses. Trinity Aquifer Trinity Aquifer Subgroup (down dip) Trinity Aquifer in Northern Bexar County Trinity Aquifer water well depths vary from shallow, hand-dug wells to drilled wells ranging from 100 feet deep to over 1,200 feet deep based on TWDB records for Bexar County. Depths are highly variable and depend entirely on site-specific topography and geology, especially faulting. Well yields in the Trinity are typically dependent on the nature of fractures and dissolution features intersected by the well bore, which can be highly variable over short distances. Well yields are typically low (less than 20 gallons per minute (gpm) ) but may occasionally be significantly higher, with yields of 400-600 gpm being reported in some wells. Water quality within a specific aquifer can be defined or characterized in a general sense, but can vary significantly based on local geology, hydrology, and structure. The Trinity Glen Rose District is located in the southern portion of the Trinity Aquifer where it underlies the Texas Hill Country. The District includes the northern third of Bexar County as well as small parts of Comal and Kendall counties and is part of the Edwards Plateau. Although it is defined by the state as a major aquifer, the water quality and productivity of the Trinity Aquifer throughout the region, including the District, varies greatly. The District is located entirely within the San Antonio River basin and is divided by three sub-basins: the Cibolo Creek, Medina River, and Upper San Antonio River sub-basins. The Cibolo Creek, Leon Creek, Salado Creek, and the Upper San Antonio River watersheds provide for surface drainage generally from the northwest to the southeast within the District. Cibolo Creek is a tributary of the San Antonio River and drains from northwest to southeast across the Trinity Group of Aquifers, where it is a major recharge feature of these aquifers. Cibolo Creek is also the county boundary between portions of northern Bexar County and adjacent counties to the north and east. Salado and Leon Creeks flow from northwest to southeast through the middle of the District, eventually joining the San Antonio and Medina Rivers to the south. As seen below, the Trinity Glen Rose Groundwater Conservation District is divided into five precincts . Recharge of the Aquifer Through Rainfall - Recharge to the Trinity Group of Aquifers occurs via local rainfall on its outcrop and flows in Cibolo Creek and through the overlying units where the Trinity Aquifer is present in the subsurface. When Cibolo Creek has water in the stretches along northern Bexar County, the losses of water from the creek are substantial and serve as a significant recharge source to the Trinity Aquifer in the District. Although this rapid recharge can occur in other isolated areas of the Trinity Aquifer in the Hill Country, it is a dominant recharge mechanism in the District. The substantial volume of recharge that periodically occurs during wet periods and flooding along Cibolo Creek creates relatively large variations in water levels in the Trinity Aquifer in the District. When water levels are high in the District, there is a natural hydraulic gradient that drives groundwater laterally to the southeast and into the Edwards Aquifer. Dolomitic Limestone Fossiliferous Limestone Shale and Sandstone Pumping of Water from the Trinity Aquifer - While the Edwards Aquifer receives large volumes of water from the Trinity Aquifer, water wells are a primary source of discharge from the Trinity in Bexar County. Historic pumping from the Trinity Aquifer within Bexar County has increased over time, from approximately 11,000 acre-feet in 2009 to greater than 23,000 acre-feet per year since 2016. Production from wells can vary significantly based on water levels in the Trinity. Water demand will continue to increase in the Hill Country, and this may add more pressure to increase groundwater production from the Trinity Aquifer in the District. Production from the Trinity Aquifer is primarily used for municipal purposes, with some production for domestic, irrigation, livestock and mining. More than 80 percent of the current groundwater production from the Trinity in the District is used for public water supply.

TGR District 2024 Annual Financial Audit TGR District FY 2026 Budget TGR District Management Plan 2021 amended 2023 TGR District Management Plan 2025 adopted 11-6-2025 TGR ENABLING LEGISLATION The Trinity Glen Rose Groundwater Conservation District was created by HB 2005 during the 77thTexas Legislature . HB 2005 was authored by State Representatives Frank Corte Jr. and John Shields and sponsored by Senator Jeff Wentworth. The bill was signed into law and took effect on September 1, 2001 and confirmed by voters in 2002. The District was created as a result of the Texas Commission on Environmental Quality (TCEQ) designating the Trinity group of aquifers lying within northern Bexar County as a Priority Groundwater Management Area (PGMA). In 2009, the 81st Texas Legislature passed HB1518 allowing an increase of production fees and allowing municipalities to request inclusion of annexed areas into the District as provided by Chapter 36 Texas Water Code. The mission of the District is to provide rules and regulations to manage, conserve, preserve, protect, maximize recharge and prevent waste of the water resources within the section of the Trinity Aquifer located in northern Bexar County.

This TGR Resource newsletter was published in November, 2025 La Niña is On Its Way TGR District remains in Stage 3 drought restrictions As the La Niña weather pattern makes its presence felt in the United States, national forecasters have released new predictions about how this climate pattern will shape our weather through the next three months. The Climate Prediction Center, part of the National Oceanic and Atmospheric Administration (NOAA), recently published its seasonal outlook for November 2025 through January 2026. Across much of the country — especially the South and Southwest — temperatures are projected to be milder weather compared to typical seasonal averages through the start of the new year. Additionally, below-average rainfall is expected across the southern tier of U.S. That could spell trouble for areas already suffering from drought. Large parts of the South and Southwest are currently classified as being in “severe” to “extreme” drought. Some of these regions, which includes Bexar County and the Texas Hill Country, depend heavily on winter rainfall to recharge their water supplies. Typical La Niña winter impacts include additional precipitation for the Northwest and Midwest to the Ohio Valley and colder than normal temperatures across the north-central U.S. The Southern U.S. experiences drier conditions and warmer temperatures. You can read an extended story here about the cyclical La Niña weather pattern and what its impacts for winter 2025-2026 will be across the country. TGR Board Approves Rules Updates The TGR Board of Directors held a public hearing in October on amendments to its District Rules for improved management of the Trinity Aquifer and approved those changes. “The rules updates will help us better align our work with the region's water planning outlook as developed by the State of Texas,” said TGR General Manager Amanda Maloukis. “The changes to the Rules also set us up for improved practices to be better stewards of the Trinity Aquifer as we develop long term goals for groundwater management designed to protect our groundwater resources for future generations.” Highlights of the changes include, statutorily required changes made by the most recent 89th Texas Legislature, as well as criteria for water wells on small tracts that maintain groundwater production in relation to their limited property right acreage, in order to protect neighboring wells, property rights, and aquifers, without requiring well permits, meters, nor production fees.

Texas Voters Approve $20 Billion Water Resources Development Plan With the population projections for Texas continuing to surge, state leaders put a major water planning and investment program on the ballot in early November which would address potential water shortages over the coming decades. With a 71 percent approval, voters across the state gave the go ahead for that $20 billion plan to invest in the State’s water infrastructure. Beginning in 2027, $1 billion per year in sales tax revenue will go toward the Texas Water Fund. That money will be used for developing new water sources, repairing existing infrastructure and flood control projects. “Texas is facing more than $200 billion in wastewater and flood infrastructure needs in the next 50 years,” Sarah Kirkle, the director of policy and legislative affairs at the Texas Water Association, said. “So this $20 billion is a really important first step.” The first round of the new funding, a total of $2 billion per biennium, will have to be appropriated by the legislature in the 90th legislative session, which will take place in 2027. Once approved, the Texas Comptroller will transfer the dedicated funds to the water fund in 2028. The funds can only be transferred if the sales tax revenue exceeds $46.5 billion in a single fiscal year. If the revenue does not reach that threshold, then no money will be transferred to the Water Fund. Today, Texas is home to about 31 million people. By 2070, that number is expected to expand to 50 million. You can read much more about the Texas Water Fund at this website. Water News from Around the State TWDB to Hold Water Project Funding Meetings The Texas Water Development Board (TWDB) is inviting people to an in-person workshop with valuable information and one-on-one opportunities to discuss regional water project needs. The TWDB program coordinators will be available at the workshop to discuss specific projects and answer questions about financial assistance programs for drinking water, wastewater, stormwater, and flood infrastructure projects. Funding Programs include: the Drinking Water State Revolving Fund (DWSRF), Clean Water State Revolving Fund (CWSRF), State Water Implementation Fund for Texas (SWIFT), Texas Water Development Fund (DFund), Flood Infrastructure Fund (FIF), Texas Water Fund, and more. The workshop will include handouts and helpful resources about the TWDB financial assistance programs. Here is a list of meetings being held in the South Texas area.

Morgan, an attorney, has served in multiple state agencies, including the Governor’s Office, Office of the Attorney General, Railroad Commission of Texas, and Texas Commission on Environmental Quality (TCEQ). Franks’ term extends through 2031 and Morgan’s through 2027. Read the full announcement for Franks here and for Morgan here. Tonya Miller has also been appointed to serve as a Commissioner of the TCEQ through 2031. Miller previously served on the TWDB Board and brings extensive experience in environmental and energy leadership, including roles with the Lower Colorado River Authority, the Texas Solar Power Association, and several divisions within TCEQ. Her appointment marks a return to the agency and underscores her long-standing commitment to environmental stewardship. Be Prepared for a Freeze While cold weather makes an appearance in South Texas for a limited number of weeks during the year, we can actually get several days of freezing weather during that time. And, when that happens, you want to be prepared to protect those beautiful native plants you’ve enjoyed all year long. “There are some native plants that will just shrug off a hard freeze, hibernate and bloom in the spring,” said Emily Green, TGR District program manager. “However, there are some plants that do need some protection when we get several days in a row of freezing weather. Thankfully, there are some simple ways to accomplish that goal.” Here is how freezing weather can damage a plant. According to Kimberly Mayer, a horticulturist with Texas A&M AgriLife Extension, when the water inside plant cells freezes, ice crystals form and can damage the cell walls, killing the cells. As temperatures rise, fluids leak out of those cells and they begin to decay. Freeze damage first appears as dark, water-soaked tissues that later turn brown or black and dry up. There are two types of freezes that South Texans should prepare for. Most people are familiar with the term blue norther, a windy cold front that moves south from Canada through the Great Plains. These northers can bring high winds, deep plunges in temperatures and precipitation which can turn into ice. “Radiative frosts” occur when the sky is clear and winds are less than 4 mph. During the day, the sun’s radiation heats the plants and soil. At night, they lose radiation back to the sky. Plants and other objects cool faster when skies are clear because of the unimpeded loss of radiation. “Homeowners can use different types of materials to cover plants, add some water to the soil if it is dry about a week ahead of a freeze, move potted plants near a building that will radiate some warmth and build a mound of mulch around the plant’s roots,” Green explained. “The idea is to get a little bit of warmth to plants during a freeze to allow them to survive. Native plants are very resilient and will make a comeback in the spring if you just get them through those extremely cold periods during the winter. You can learn more about protecting plants and pets during a freeze at Texas A&M AgriLife Extension Service. TGR District Sill in Stage 3 Drought If you’ve been watching the Trinity Glen Rose District’s drought dashboard over the past several months, you might have noticed that Bexar County almost went from the “extreme drought” classification down a step to “severe drought” after those huge summer rains in July. But, the past few weeks, the drought map has reverted to nearly all of Bexar County being classified as extreme drought. Given those facts, the District remains in Stage 3 of its drought management plan. Here are the top three ways people living in Bexar County can reduce their water use to help protect Trinity Aquifer well levels from dwindling lower than their near historic lows being measured now. The growing season is over. So please turn off all in-ground sprinkler systems and only spot water by hand if absolutely necessary. Fix any water leaks you might have at your residence. Try not to do extensive planting now. New plants require extra watering to establish their root systems. Weather forecasts for the coming months are showing South Texas could be facing slightly lower than normal rainfall. That will obviously not help the current drought conditions, so we all need to pitch in to help preserve our local aquifers by conserving the water they provide. GARDENING GO Check out what’s happening in this edition of your favorite landscape show - Go Gardening! Go Gardening Teaches Fall Planting, Design The November Go Gardening Show closes out Season 4 and we want to thank the Gardening Volunteers of South Texas for their initiative and all the contributors for making the year a great one. To wrap up Season 4, the Go Gardening production team headed over to the home of Dana Nichols, who recently retired from the San Antonio Water System after spending a career there in the water conservation department. She is a landscape expert and a lot of fun to be around as you will see in segment one. She recently had a neighbor remove a huge oak tree which shaded her entire front yard. So now she's thinking about native plant changes which do better in full sun. We had a great time and learned a great deal from Dana. Next, Mark Peterson, met up with the president of the Gardening Volunteers of South Texas, Andrew Waring, to talk about ways to protect those beautiful native plants from a serious freeze if we get one of those this winter. Mark and Andrew spent the last few minutes of the show expressing the Go Gardening Team's appreciation to viewers and show sponsors. Click here to watch the latest Go Gardening Show.

TGR's Drought Tolerant Plant Picks Having a water-saving garden doesn’t mean you have to sacrifice color and even year round color in your landscape. Once the temperatures cool, any of the native perennials can go in the ground for next year’s show. Here are two great suggestions. The Prairie verbena , Glandularia bipinnatifida (top photo), is an annual or short-lived perennial that reseeds readily. Once established, its long bloom period will provide color when other wildflowers have faded. Does well in both sun and part shade and doesn’t mind our caliche soils. As with most natives, only water when the plant looks sad in the morning, not when they look droopy in the evenings after a hot day. May be found at local nurseries and regional native plant sales. The native Tropical sage , Salvia coccinea (bottom photo), checks a ton of boxes: long-blooming, perennial, reseeds readily, adds vertical interest, and a favorite of butterflies and hummingbirds owing to its bright red, tubular flowers. The pungent foliage makes it a less-preferred snack for our resident deer. Tolerates sun to shade as well as a spectrum of soil and water conditions. Just trim back spent flower heads to promote bushier growth. Easily found at our local nurseries. DROUGHT DASHBOARD With the severity of the current drought conditions expected to continue into 2026, the TGR District is providing up to date information about these conditions affecting local aquifers and how you can help. At the TGR Drought Dashboard on the District’s website home page, you will find the current U.S. drought monitor map, the rainfall chart from the National Weather Service, current drought news articles and a link to some great water conservation recommendations at our Don’t Waste the Wet Stuff page. Just click on this link to check it out. DID YOU KNOW? TGR That’s a lot of water… Groundwater supplies approximately 55 percent of the water used in the State of Texas each year. Roughly 15 million acre-feet of water is pumped from aquifers like the Trinity Aquifer, Edwards Aquifer, Carrizo Aquifer and others. That equates to nearly five trillion gallons of water. Here’s the equation. One acre-foot = 325,851 gallons. Multiply that number by 15,000,000 acre-feet to get 4,887,765,000,000.

TGR EVENTS 2021 Watersaver Landscape Tour Videos The Trinity Glen Rose District cosponsored the 2021 Watersaver Landscape Tour. This event was held online and more than 350 people took time to watch. In case you missed it, you can watch the tour videos featuring some beautiful, water-saving landscapes from around San Antonio. We'd like for you to come away with a few ideas on how you can improve the look and feel of your yard while substituting native plants for grass and other nonnative plants that require lots of water to keep healthy. Many thanks are due to the homeowners who agreed to not only let us show their yards but also participate in the videos. They are quite informative. One last item...you can download the plant lists we put together for each yard, which should help you next time you visit a nursery to pick the right plants for your home's landscape. We hope you enjoy these videos as much as we did in putting them together.

DROUGHT INFORMATION TGR Board Adopts New Drought and Conservation Management Plan The Trinity Glen Rose District Board adopted amendments to its Drought and Conservation Management Plan at its October 2024 board meeting.

TGR Drought and Conservation Management Plan Managing Drought PDF TGR District Moves to Drought Stage 3 Current Drought Stage: Stage 3 as of November 1, 2024 With water well levels already near historic lows and fall rainfall deficits at around five inches, the Trinity Glen Rose Groundwater Conservation District (TGR) declared STAGE 3 water restrictions in compliance with the District’s Drought Contingency Plan effective as of Friday, November 1. “We are seeing very negative trends in our Trinity Aquifer monitoring water well levels continue. Additionally, we’re seeing that same type of problem with the Edwards Aquifer,” said TGR General Manager Amanda Maloukis. “So as the Edwards Aquifer Authority is considering for the first time ever declaring Stage 5 of their drought plan, we know that it is critical for us to declare Stage 3 of our drought plan. These two drought stages are the highest levels of required conservation measures and they’re being invoked due to our persistent drought which has prevented water wells from replenishing to get us back to somewhat normal water levels.” Since September 1, San Antonio has recorded a little less than 1.5 inches of rain. That’s 5 inches below average for the first eight weeks of fall. This is also the driest start to fall since 2008 which was also one of the area’s toughest droughts. As of now, it has been two months since any rain has fallen in San Antonio. Given those very dry conditions, the current US Drought Monitor lists the majority of Bexar County as being in (D3)-Extreme Drought . “How can people help our aquifers? First of all, the growing season has stopped, so there should absolutely be no lawn watering happening,” Maloukis stated in her call to action. “Even though our Stage 3 irrigation measures limit watering to once every other two weeks, that restriction is really written for summer months when landscapes do need a little water to stay alive. So, please, turn off all sprinkler systems and hand water only where and when necessary. Then, we would ask families to talk about conserving water. We can save a lot of water by taking short showers, washing only full loads of clothes and dishes and never just letting a faucet run. You must have an active purpose for using water to turn the faucet on.” Maloukis concluded by reminding people that droughts are a part of living in South Texas. And, at some point, those droughts end with plentiful rainfall. But, until that much needed precipitation returns, it is up to every family and business operation to take these water conserving measures seriously. The conservation measures outlined and strongly encouraged under TGR’s Stage 3 drought plan include all conservation measures from Stage’s 1 and 2 unless replaced by Stage 3: Watering with an irrigation system, sprinkler, or soaker hose is allowed once every other week, from 5- 10 a.m. and 9-12 p.m. on your designated watering day as determined by your address. Watering with drip irrigation may run one day a week, on Friday, from 5-10 a.m. or 9-12 p.m. Watering with a hand-held hose may occur any time and any day. Water use reduction goal of 15%. Installing newly planted landscapes is highly discouraged. Aesthetic fountains should not be utilized unless an alternative source of water other than groundwater. Do not wash parking lots, driveways or sidewalks unless health and safety is a risk. The use of a commercial car wash facility that recycles water is allowed any day. Alternate sources of water are highly encouraged such as rain water harvesting, reclaimed condensate, reclaimed grey water, recycled water, and other non-groundwater sources. Below is a chart outlining the day of the week your household is allowed to water, which is every other week during Stage 3 drought restrictions. But, as mentioned, with the landscape growing season over for 2024, there should not be any lawn watering with sprinkler systems occurring now.
