The Trinity Glen Rose District partners with many great entities to teach water conservation and pollution prevention. Pollution Prevention - See Park Slide Shows Below Practicing Pollution Prevention Each Day Over the next few months, the Trinity Glen Rose Groundwater Conservation District is going to be featuring some of the beautiful parks that are located within the District’s boundaries. The bottom line is that parks, water and pollution prevention go hand-in-hand. So, the more you know about how those three work together, the more likely you’ll be to help prevent pollution from getting into our local rivers and aquifers. So that’s why we’re calling this series “Learn and Live.” Each month, we will inform you about one of the must-see parks in Northern Bexar County. And with that learning, we hope you will not only want to visit that park, but you’ll also want live your life by developing the best pollution prevention habits that researchers have developed so far. Learning About Pollution Prevention Historically, cities have paved roadways, sidewalks, trails, parking lots, sports courts, alleys, driveways, and other surfaces to reduce the annoyance and cost of slippery mud and blowing dust. Unfortunately, having so many hard, water-repelling surfaces (along with a vast number of urban rooftops) can be environmentally harmful. After it rains, vast amounts of water, now called “stormwater,” will collect in these areas, pick up the grease, grime and other pollutants that are deposited on them each day, and then head for a water source like a creek, river or aquifer. Here are some of the ways dirty stormwater can pollute a water supply: most stormwater runoff escapes natural cleansing by plants, rocks and soil; without nature slowing down the stream of water after a rain, higher amounts of water are funneled to local streams; urban streams become prone to flash flooding from rapid runoff, resulting in severe scouring, erosion, and reduction of plant life; once stream beds are scoured, flooding becomes more common. The solution is to hold back the water where it hits, slow it down so that the destructiveness of erosion and contaminants is controlled, and that it is naturally cleaned it before it reaches a waterway or aquifer recharge feature. So, now that you’ve learned how unabated stormwater can create flooding and pollution issues for our aquifers and streams, you can also understand why maintaining and increasing large natural areas like parks is so important to our community. The important point to never forget is that the less runoff, and the slower the runoff we have, the less damage there is to rivers and aquifers and the overall environment. Living Pollution Prevention Here are the Top 6 Pollution Prevention Habits You Should Develop Practice water conservation in your home each day. The less water you use, the more water is left in the Trinity Aquifer for future use. Practice energy conservation in your home each day. Large amounts of water are needed to cool power plants that provide electricity to our city. Less energy production requires less water to be used. Use non-toxic cleaning chemicals in your home. Never dump oil or others types of solvents on the ground or in the street where they can run off into a stream or an aquifer. Use only environmentally-safe weed-killers and fertilizers on your landscapes. Always pick up your pet's waste and dispose of properly. Pet waste that runs off into a creek or stream only increases the bacteria levels in that body of water. Enjoy the parks and advocate for more green spaces in your communities. “Learn and Live” at Stone Oak Park 3V3A0300 IMG_6942 3 3V3A0119 3V3A0300 1/28 Numerous natural areas and community parks beautify Northern Bexar County where the Trinity Glen Rose Groundwater Conservation District (TGR) works to preserve and protect the Trinity Aquifer each day. In addition to these parks’ aesthetic value, they also play a major part in preventing pollution from entering the Trinity Aquifer and Edwards Aquifer which are both critical to the water supply in Bexar County. To highlight pollution prevention message, TGR is bringing its constituents an informative series about the six major parks and natural areas in the district. This month, we are highlighting Stone Oak Park located at 20395 Stone Oak Parkway. Stone Oak Park features a 3.2-mile loop trail located in the heart of the Stone Oak neighborhood. Despite its urban setting, park designers succeeded at creating a very rustic feel as the trails wind through some traditional South Texas hill country scenery. Currently, there are some beautiful wild flowers dotting the trails, and with the recent rains, the park is quite green. The park also contains some interesting sculpture art and some work out stations (push ups, site ups, pull ups) for those looking for an additional level of exercise. The trails are rated as moderate, and dogs are also welcome but owners must be keep them on leash. “Learn and Live” at Panther Springs Park Panther Springs Park Panther Springs Park Panther Springs Park Panther Springs Park 1/21 Panther Springs Loop is a 3.6-mile lightly trafficked loop trail located near San Antonio, Texas that features beautiful wild flowers in the spring, hill country type wooded areas and many beautiful open meadow-like vistas. The trails are paved and considered good for all skill levels of hikers, walkers and runners. The park, which opened in March of 2015, consists of 279 acres which were donated by Dan Parman and the San Antonio River Authority (SARA). The dog park which is located near the entrance of the park includes areas for larger dogs and one for smaller ones. Bird watchers have documented 46 different species in the park to include the Greater Roadrunner, two species of hawks and numerous other types of smaller, colorful birds. The San Antonio River Authority collaborated with the City of San Antonio in the development of Panther Springs. SARA’s portion of the project included design and construction work to improve the water and sediment conveyance in the existing natural channel. The agency continues to monitor the stream for changing conditions as the landscape slowly changes over time. Preserving the community’s natural areas goes a long way toward helping efforts to maintain excellent water quality in local aquifers and other waterways. That is why the Trinity Glen Rose District is urging you to learn about the parks and to live a little by visiting each one to experience the environmental beauty and ecological benefits they provide. “Learn and Live” at Friedrich Wilderness Park Windmill along Water Trail woods 1 bridge 1 Windmill along Water Trail 1/23 Numerous natural areas and community parks beautify Northern Bexar County where the Trinity Glen Rose Groundwater Conservation District (TGR) works to preserve and protect the Trinity Aquifer each day. In addition to these parks’ aesthetic value, they also play a major part in preventing pollution from entering the Trinity Aquifer and Edwards Aquifer which are both critical to the water supply in Bexar County. To highlight pollution prevention message, TGR is bringing its constituents an informative series about the six major parks and natural areas in the district. This month, we are highlighting Friedrich Park located north of Loop 1604 on Milsa Drive. Friedrich Wilderness Park offers approximately 10 miles of hiking trails with varying degrees of difficulty. It is home for rare birds, terrestrial orchids, steep hills and deep canyons. It is internationally known for bird watching. Perched on the edge of the Balcones Escarpment, Friedrich is a nesting site for the endangered Black-capped Vireo and the Golden-cheeked Warbler. In 1971, Norma Friedrich Ward bequeathed 180 acres of land on Heuermann Road near Leon Springs to the City of San Antonio for use as a public park. She also gave $100,000 to make improvements to the land. It was Mrs. Ward’s wish that the natural vegetation and native trees and shrubs be protected and that native birds and wildlife be protected and encouraged to use the park as a sanctuary. The following year, Wilbur Matthews and Glen Martin donated another 52 acres to enlarge the park according to the same guidelines specified by Mrs. Ward. The park was developed with a grant from the Texas Parks and Wildlife Department and was dedicated on August 31, 1978. Preserving the community’s natural areas goes a long way toward helping efforts to maintain excellent water quality in local aquifers and other waterways. That is why the Trinity Glen Rose District is urging you to learn about the parks and to live a little by visiting each one to experience the environmental beauty and ecological benefits they provide.

To highlight pollution prevention message, TGR is bringing its constituents an informative series about the six major parks and natural areas in the district. This month, we are highlighting Eisenhower Park located north of Loop 1604 on NW Military Highway. Dwight D. Eisenhower Park is a 320-acre park managed by the City of San Antonio containing excellent examples of Hill Country landscapes, including wooded dry creek beds and rocky canyons. The park features more than 6 miles of paved and unpaved trails. There are seven different trails in the park most of which are paved. The 2.5 mile Hillview Trail circles the perimeter of the park and leads to the observation tower located about midway through the hike. The one-mile Cedar Flats Trail runs through the heart of the park and contains a combination of paved and rugged terrain. All of the trails have plenty of signage posted and many of the plants and flowers you will see are marked as well. Eisenhower Park is pet friendly, but is a designated natural area park which means roller blades, skateboards and bikes are not allowed on the trails. There are several pavilions in the park for barbecues and picnics that are located near the entrance of the park. Various park amenities are available for rental and you can learn how to make a reservation at this link. The City of San Antonio also offers various types of classes in the parks and you can learn about them at this link. Preserving the community’s natural areas goes a long way toward helping efforts to maintain excellent water quality in local aquifers and other waterways.

Government Canyon State Natural Area Government Canyon Cover 3V3A6961 3V3A7100 Government Canyon Cover 1/31 Government Canyon State Natural Area is part of the Texas State Parks system. It is designated a natural area rather than a state park because its primary focus is protection of the property's natural resources. Given that designation, access and recreational activities may be restricted if the Texas Parks & Wildlife Department (TPWD) deems such action necessary to protect the environment there. The reserve is located in northwestern Bexar County inside the Trinity Glen Rose Groundwater Conservation District’s boundaries. It protects a large, relatively pristine tract of Hill Country terrain that is home to numerous and diverse species of plants & wildlife and the upper Culebra Creek and Leon Creek watersheds. The approximately 12,000 acres of land Government Canyon State Natural Area occupies was originally purchased to protect the critical aquifer recharge zone which diverts rainfall into the Edwards Aquifer, the main source of drinking water for San Antonio. First opened to the public in October, 2005, Government Canyon State Natural Area offers more than 41 miles of trails. Visitors can camp, attend a program or guided hike, geocache, picnic, take nature photos and look for birds and other wildlife. For those looking for a place to go birding, Government Canyon is a good place to find the endangered Golden-cheeked warbler. One of the most visited features on the property are the dinosaur tracks which are located about 2.5 miles from the visitor’s center. Scientists believe the tracks were made about 110 million years ago. At that time, this location was actually near the shoreline of the Gulf of Mexico. The dinosaurs would walk along the moist, fine-grained mud and leave tracks which would then be exposed to the sun allowing them to dry and harden. Erosion over time have exposed the tracks for today’s people to discover, study and protect. The Witte Museum, University of Texas at San Antonio, Trinity University and Texas Parks and Wildlife are continuing to study and preserve these unique dinosaur tracks today. You can learn more about Government Canyon here. Crownridge Canyon Park Entrance Crownridge Canyon Map 3V3A6275 Entrance 1/15 Crownridge Canyon was the first City natural area developed as part of the Edwards Aquifer Protection ballot initiative. The 200-acre preserve features Level 1 ADA trails and Level 4 hiking trails through a variety of habitats. Features include a canopy level bridge overlook, beautiful forested canyon bottoms, hillside vistas, and restored grasslands. There are excellent opportunities to view the endangered Golden Cheeked Warbler during its nesting season. This park features interpretive elements highlighting local flora, fauna, geology and the aquifer recharge cycle, as well as the area’s early human inhabitants. The landscape at Crownridge feature native plants of northern Bexar county. Many are numbered and can be identified using the Natural Areas Plant Key. Crownridge Canyon Trails offer both gentle Level 1 trail surfaces and more natural and challenging Level 4 surfaces. Trail markers will soon be placed along the trails to identify native plants.

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. 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.

TGR District 2025 Annual Financial Audit TGR District FY 2026 Budget 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.
