Looking for water data? You've come to the right place. You can find water well locations and data at this page. WELL OWNERS RESOURCES Water Quality Testing of Your Well Safe drinking water for you family and friends relies on frequent testing Because no federal, state, or local entity ensures the safety of private well water, the responsibility for monitoring it falls to the well owner. Compared to people who consume public drinking water, private well owners are more likely to be exposed to unsafe drinking water. Water Quality Testing Basics You will need to find out the quality of the water in your aquifer. Some information about the aquifer water may be readily available from public utilities and water companies. They are required by federal and state law to report water chemistry to consumers. (TGR link for Trinity Aquifer water quality.) Contact the water utility for a copy of the water quality report for information about local water quality issues. However, water quality information on exempt household wells is not recorded or made available through any public agency unless the well owner has given permission. Have your water tested whenever: You suspect it may be contaminated. If you notice a change in color, taste, or odor of the water. The pump or well has undergone maintenance recently. People who drink the water have experienced a change in health, especially stomach-related illnesses. The well water is cloudy or smelly, or tastes bad, it probably does not conform to drinking water quality standards. If you live near oil and gas fields, you should have the water screened for non-refined hydrocarbons in addition to annual testing for coliform bacteria, nitrate, and total dissolved solids. Maintain Water Quality Testing Records To protect your water supply, you need to keep records on each well, manage potential sources of contamination, and test your water at least once a year. Record the location of all wells on your property, and keep a file on each well. Each well will have a unique identification number assigned by the driller. Use this number to track historical information, which may be available from the following sources: Texas Water Development Board Groundwater Database: Licensed water well drillers must submit reports to the state for each well they drill. More than 130,000 wells have been recorded in the TWDB groundwater database since 2001. For more recently drilled wells, your state well report may be found here: TWDB Water Data Interactive Map Texas Commission on Environmental Quality Water Well Report Viewer : For historic well records, TCEQ Water Well Viewer For assistance, call 512-239-4600 or email gpat@tceq.texas.gov Texas Alliance for Groundwater Districts: http://www.texasgroundwater.org/ Your groundwater may be managed and protected locally through a groundwater conservation district. Groundwater districts are governed under chapters 35 and 36 of the Texas Water Code. Texas Water Development Board: TWDB Groundwater Conservation Districts webpage Major Flooding Can Contaminate Private Water Wells Large flood events, which South Texas is prone to, can contaminate your private water well. However, disinfection can eliminate or reduce harmful bacteria, viruses, or other microorganisms that may be found in your drinking water after flooding in your area. If your well system is damaged, the following instructions for the disinfection process will not work. An indication that your well is damaged can be a decrease in water pressure once turned on. Contact a certified well or pump contractor for examination. It is extremely important not use contaminated water for: drinking, cooking, making ice, bathing in any form, washing clothes or dishes. After a flood, ingesting or being exposed to contaminated water can cause illness. If you think your well system may be contaminated, some alternative options for safe include: using bottled water, boiling water for five minutes, using water from a source you know is not contaminated.

DROUGHT INFORMATION TGR Drought and Conservation Management Plan Managing Drought PDF Trinity Glen Rose District Moves to STAGE 2 Drought Restrictions Published June 25, 2026 After considering rising levels in the Trinity Aquifer monitoring wells due to significant rainfall over the past several months, the Trinity Glen Rose Groundwater Conservation District (TGR) will be moving from Drought Stage 3 to Stage 2 of its drought management plan. “The District is pleased to report that with more rain in the long-term forecast and the recent downpours replenishing the District’s monitoring wells, we’ve decided to go to Stage 2 of our drought plan which is a reduction from the highest level drought Stage 3 which we’ve been in since November 1, 2024,” said TGR General Manager Amanda Maloukis. “There is still more room for wells to recover, so we are going to be a bit cautious in our drought approach over the next several months. We just published an article about a “Super El Niño” possibly bringing a strong rainy season later in 2026 to Texas. While we all hope that this much needed rain continues throughout the rest of the year, we haven’t reached a point of saying this current five-to-six year drought is over.” From a water conservation standpoint, the District is urging home and business owners to take maximum advantage of the recent precipitation by keeping automatic sprinkler systems off and only hand watering where necessary. The soil is still fairly saturated with water and plants know how to access that water, so there is no need to waste water by putting more on landscapes now. You can read more about the TGR District Drought Plan at: www.TrinityGlenRose.com/drought . STAGE 2 Drought Measures (Includes all measures of STAGE 1 and Year-Round Conservation) 1. Water use reduction goal of 10%. 2. Watering with a hand-held hose may occur any time and any day. 3. Watering with a spray irrigation system, sprinkler, or soaker hose is allowed to only once a week, from 5-10 a.m. and 9 p.m.-12 a.m. on your designated watering day as determined by your address in Stage 1. 4. Watering with drip irrigation may run up to two days a week on Monday and Friday, before 10 a.m. or after 9 p.m. Year-round Conservation Measures This stage is what most people would consider normal seasonal climate conditions for the area. Year-round watering rules are in effect when no drought conditions are active. The District strongly encourages homeowners, home owner associations, homebuilders and/or developers, exempt or non-exempt well users to incorporate these conservation practices. Specifically, the incorporation of the following best management practices: 1. Rain Sensors - rain sensors should be installed and maintained on all irrigation systems equipped with automatic irrigation controls and inspected annually. 2. Xeriscape Option - Homebuilders and/or developers subdividing lots and/or constructing new single family residential homes should offer a xeriscape option in any series of landscaping options offered to prospective home buyers. 3. Rainwater Harvesting Systems - Homebuilders, developers, Homeowner Associations, and homeowners should consider the installation of rain harvesting systems. Rain harvesting systems can reduce reliance on common water supplies with a low-cost investment. 4. Improve the quality of home irrigation systems - Homeowners, Homeowner Associations, homebuilders, and developers should consider installing or replacing irrigation systems with an efficient system. This can lessen the strain on groundwater resources. This article was published November 1, 2024 TGR District Moves to Drought Stage 3 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.

RAINWATER HARVESTING Rainwater harvesting is the capture, diversion, and storage of rainwater for a number of different purposes including landscape irrigation, drinking and domestic use, aquifer recharge, and stormwater abatement. In a residential or small-scale application, rainwater harvesting can be as simple as channeling rain running off an unguttered roof to a planted landscape area via contoured landscape. To prevent erosion on sloped surfaces, a bermed concave holding area down slope can store water for direct use by turfgrass or plants. More complex systems include gutters, pipes, storage tanks or cisterns, filtering, pump(s), and water treatment for potable use. Rainwater Harvesting Q&A Just hover your cursor over the photo to see the answer for each question. What are the basic parts of a rainwater harvesting system? Catchment surface: the collection surface from which rainfall runs off, typically a roof on a home or building Gutters and downspouts: channel water from the roof to the tank Leaf screens, first-flush diverters, and roof washers: components which remove debris and dust from the captured rainwater before it goes to the tank One or more storage tanks, also called cisterns Delivery system: gravity-fed or pumped to the end use Treatment/purification: for potable systems, filters and other methods to make the water safe to drink What are the benefits a rainwater harvesting system? The water is free; the only cost is for collection and use. Rainwater provides a water source when groundwater is unavailable, or it can augment limited groundwater supplies. The zero hardness of rainwater helps prevent scale on appliances, extending their use. Rainwater is superior for landscape irrigation. Rainwater harvesting reduces flow to stormwater drains and also reduces non-point source pollution. Rainwater harvesting reduces consumers’ utility bills. How much water can I capture? The basic rule for sizing any harvesting system is that the volume of rainwater is that can be captured (the supply) must equal or exceed the volume of water used (the demand). In theory, approximately 0.62 gallons per square foot of collection surface per inch of rainfall can be collected. In practice, however, some rainwater is lost to first flush, evaporation, splash-out overshoot from the gutters in hard rains and small leaks. How do I get started with a rainwater harvesting system? Rainwater collection systems can be as simple as collecting rain in a barrel or as elaborate as harvesting rainwater into large cisterns to supply your entire household. Rainwater storage systems and equipment can be purchased at local home improvement stores, lawn and garden stores, and even ordered online! A great resource for you to use is the Texas Water Development Board's Rainwater Harvesting guide. Just click the link below to download a PDF of that guide. Plus, you might want to read the Tax Exemption information as well. The Trinity Glen Rose District put together a "how to" video for building your own rain barrels. Check it out below.

Safety is always a must when working with power tools. So, we strongly recommend you wear a pair of safety glasses or some sort of eye protection during this project. Where to find an empty barrel: Dave the Barrel Man (www.davethebarrelman.net ); 811 Roosevelt, San Antonio, Tx 78210; Phone: 210-534-5416 Tanks A Lot - 39332 IH 10 West, Boerne, TX 78006; Phone: 830-331-7330; http://www.tanksalottx.com/ Barrels by Joel - Phone: 210-717-6850 https://barrelsforsale.net/ Home Depot/Lowes - small barrels Many on-line resources - Watch out for shipping costs! Tools needed: drill - 3/8 to 1/2 hp Paddle (spade) bit, 15/16" and 2 3/8" hole saw Set of hole saws or a jigsaw to make a 6" hole in the top Materials needed: A ¾” brass faucet (hose bibb) 2” male PVC connectors & electrical Nut Tube of silicone (bathtub) Barrel Step 1 - Drill a hole in the top of the barrel for rainwater to flow into. Mark a spot in the top of the barrel. It doesn’t have to be the middle. Use a 6” hole saw to cut it out. Or using the bottom of a one-gallon plastic pot, mark a circle around the bottom of the pot. Drill a ¼” hole on one side of the circle and saw the circle out. Saw to the outside line you drew with the plastic pot. Step 2 - Drill the overflow hole. Using the pot as a depth gauge, mark and drill the overflow hole just beneath the depth of the pot. Use the 2 3/8” hole saw. Step 3 - Drill a hole for the hose bibb. About 3 inches up from the bottom of the barrel, drill a 15/16” hole for the 3/4” hose bibb. Step 4 - Install the hose bibb. Put a little silicone around the threads on the hose bibb, push down and screw it in. It will be sealed when you finish. Be sure to point the hose bibb to the side for better access. About 3 inches up from the bottom of the barrel, drill a 15/16” hole for the 3/4” hose bibb. Step 5 - Install the overflow. Insert the 2” adapter with the male threads through the hole. Thread the 2” electrical nut on adapter inside of the barrel. Step 6 - Screening out debris. Place mosquito screen in bottom of pot & add rocks (about 2-3 inches deep) and place it in the top of the barrel. This is the filter to keep out the large stuff off the roof. Step 7 - Connect your rain barrel to the downspout. Place your rain barrel in a location where it will capture rain running off of the roof. Or, you can attach a diversion to your existing downspout that will direct water into the barrel. Other Considerations Level your barrel!! Elevating barrels provides room for watering cans and increases gravity flow If linking barrels together, place an overflow pipe on last barrel Pond Pumps and transfer pumps can be used to increase flow Consider placement of faucet if you live in a windy area If you have children, strongly advised to anchor the barrel to your home Connecting two or more barrels together is easy! 1.If you want to hook two or more barrels together, use the overflow hole as the hookup between the barrels. 2.Use a piece of 2” PVC pipe with a male-threaded connector glued to the end and screw it into the female fitting on the inside of the first barrel. Do the same thing on the other end of the pipe and on the next barrel until all the barrels are hooked up. 3.If you do the same setup on the bottom of all the barrels, the water will empty out of all the barrels at the same time. PLUS, you only need one hose bibb in one barrel.

Here you will find the latest research by the Trinity Glen Rose District in our effort to learn about the Trinity Aquifer. Water Planning The TGRGCD was created to address groundwater issues or problems within the District overlaying Trinity group of aquifers. The District includes data from the TWDB’s Groundwater Availability Models (GAMs), input from the Groundwater Management Area 9 cooperative planning process, public input, and the most current and accurate site-specific data available in the development of its management plan to preserve, protect and conserve the Aquifer. The District also cooperates with adjacent groundwater districts, Groundwater Management Area 9, Regional Water Planning Groups, local water purveyors and stakeholders, and adjacent counties with similar aquifers and/or groundwater usage to ensure a collaborative means of protecting water supplies in this area of the state. Groundwater Management Area 9

Looking for water data? You've come to the right place. You can find water well locations and data at this page. RECHARGE ENHANCEMENT From Rain to Recharge Aquifer recharge enhancement (ARE), also known as Managed Aquifer Recharge (MAR) or Aquifer Storage and Recovery (ASR), is the intentional human process of adding water (like stormwater, treated wastewater, or surface water) to aquifers to replenish groundwater supplies, buffer against drought, and improve water security. Methods include infiltration basins, injection wells, and in-channel modifications, with benefits like reduced evaporation, water treatment as it percolates, and cost-effectiveness compared to surface reservoirs. The Trinity Aquifer recharges slowly from rainfall on its outcrop areas and seepage from streams, with water moving through its complex fractures and layers, unlike the faster Edwards Aquifer, with recharge rates varying greatly by region, often only 4-6% of rain, and is affected by urban development reducing natural infiltration, making artificial recharge efforts crucial for sustainability. Watch the general water cycle 3-D model simulation below to see how precipitation falls on the Earth's surface, collects in rivers and creeks running across the land and then recharges an aquifer, like the Trinity Aquifer, through fractures and sinkholes in the riverbed. The rainfall then makes it way through various fissures in the various rock formations that make up the aquifer. Healthy soil and vegetation improve the land’s ability to absorb water. Trinity Aquifer Recharge Occurrence - How Recharge Occurs Precipitation & Streams : Rain falling directly on the aquifer's exposed (unconfined) areas, as well as water seeping from rivers and ponds where the ground slopes downward, replenishes it. Karst Features : Water travels through fractures, bedding planes, and solution cavities (karst) in the limestone, allowing for both rapid flow and localized storage. Inter-Aquifer Flow : Some water can also move from the overlying Edwards Aquifer down into the Trinity in certain areas, though this is less significant than direct recharge. Recharge rates are not uniform; some sections replenish quickly, while others take much longer, making management challenging. Common Recharge Enhancement Techniques Berms and Swales – To slow and sink water. Rock or Brush Structures – To slow and sink water. Grassed Waterways – Shaped Channels lined with vegetation that slow rainfall runoff and encourage infiltration. Check Dams – Small barriers placed in drainage ways that slow water, spread it out, and increase soak-in time. Rangeland Restoration – Improving soil health and perennial vegetation so the land absorbs more rainfall. Recharge Basins – Engineer shallow basins that temporarily hold stormwater, letting it soak in instead of running off. Brush Control - removal of invasive brush species such as juniper, mesquite, and salt cedar is used to increase water yield and aquifer recharge. (See more near the bottom of this page) The video below is a segment from a Trinity Glen Rose District sponsored Go Gardening Show. The video was shot at the Edwards Aquifer Field Research Park in Northern Bexar County along the Cibolo Creek. You'll get a great look at how berms, swales, small rock dams, enhanced vegetation and shallow recharge basin s help move water from rain to recharge. Cibolo Creek in Northern Bexar County Cibolo Creek in Northern Bexar County Cibolo Creek is a major Recharge feature to the Trinity Aquifer Recharge for the Trinity Group of Aquifers occurs via local precipitation on its outcrop. The outcrop area takes in recharge flow from the Cibolo Creek and other overlying units where it is in the subsurface. When Cibolo Creek has water in the stretches along northern Bexar County, the movement of water from the creek into the groundwater 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. Helpful Resources - From Rain to Recharge Soil Erosion is a form of soil degradation in which the top layer of soil is carried away by wind and water. Rain and channelized water flow dislodge and wash exposed soil downhill. This cumulative loss of soil poses a major challenge to landowners and managers. The Hillside Stewardship guide highlights a series of erosion-control structures that Hill Country landowners and managers are using to slow and sink water into the land. Just click on the cover photo of the guide to the left to download it. If you'd prefer a video on the topic, you can watch the "Hill Country Groundwater Recharge With Bryan Hummel " by clicking the video link. Brush Control Texas brush control, specifically targeting species like juniper, mesquite, and saltcedar, is used to increase water yield and aquifer recharge by reducing excessive transpiration. The Water Supply Enhancement Program (WSEP) by the TSSWCB incentivizes managing these deep-rooted plants in priority areas to conserve water, improve spring flows, and reduce erosion. Brush Busters is a cooperative program of the Texas AgriLife Research and Extension Service to expedite the adoption of Tactical Brush Management Systems (TBMS) technology. Brush Busters methods are easily understood, even by those with little or no previous experience in brush control. We recommend only “select” treatments capable of killing at least 7 out of 10 of the plants treated. Brush Busters methods make every attempt to keep equipment costs and complexity to a minimum, and whenever possible, to use non-restricted herbicides. One-page pamphlets are available from most County Extension offices that describe, in a simple 3-step process, the Brush Busters control methods for mesquite, prickly pear and cedar. Videos are available that demonstrate the Brush Busters control methods available at this link, https://texnat.tamu.edu/about/brush-busters/.

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.
