Take advantage of the Trinity Glen Rose District's conservation program incentives. 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.

Camp Bullis Sentinel Landscape Regional Conservation Partnership Program Learn about Land Management Priorities The priorities of this project involve addressing ecological resource concerns that will benefit both the mission of Joint Base San Antonio-Camp Bullis and the land stewards and residents in the project area. Land Management Resource Concerns The ecological concerns and priorities in the project area are water quality and conservation, plant health and restoration of our native plant communities, soil quality, and improving habitat for grazing and wildlife. Land Management Practices To address these resource concerns, eligible practices are selected as the tools and processes to get conservation on the ground. Eligible land management practices will focus on water quality and riparian health including planting and protecting vegetative buffers around waterways. Waterways that are named and flowing into Camp Bullis will have a higher priority for funding. Other practices will be used to improve and restore upland communities. These practices will include prescribed grazing, selective brush management, and native plant restoration for wildlife and pollinator species. Practices will be also used to improve soil health. Our project specialists will meet with you and design a conservation plan that will specifically meet your needs and the needs of the land. Funding will be attached to these conservation plans to aid in implementation. Read more by clicking on this link.

TGR Board Adopts Changes to Precinct Boundaries Redistricting is part of the election process in the United States. And because the Trinity Glen Rose Groundwater Conservation District’s (TGR) board members are elected, the district recently reviewed its population changes over the past 10-year period and found it needed to adjust its boundaries due to population shifts in the precincts. The objective is to balance the per capita representation for each precinct in order to give all district constituents an equal say via their elected representatives regarding district policies and future directions. The TGR Board used the following criteria to make its final boundary adjustments: begin and end with identifiable boundaries maintain communities of interest & neighborhoods use whole voting precincts if possible base plan on existing districts adopt districts of relatively equal size draw districts that are compact and contiguous keep existing incumbents in their districts to preserve previous voter wishes tailor plan to comply with the Voting Rights Act The Board opened its planning documents up for public review and comment. At the Dec. 4 board meeting, the Board held a public hearing to receive any final comments before taking official actions to change the TGR precinct boundaries. After a thorough planning process and public comment period, the TGR Board officially changed its boundaries to reflect a more consistent population base in each precinct. Due to the change in boundaries, the district will be holding an election to fill all precinct seats in May, 2022. Click here for more information. Please see the charts below which show the population unbalance before the boundaries were changed and then the chart with showed precinct populations in balance after the official changes were made to the precinct boundaries. These new boundaries will remain in place until the next U.S. census reports are received.

ABOUT THE TGR DISTRICT TGR Management Plan TGR District Brochure The Trinity Glen Rose Groundwater Conservation District (TGRGCD or District) was created for the purpose of conserving, preserving, recharging, protecting and preventing waste of groundwater from the Trinity Aquifer in Northern Bexar County. The District was also created in response to the Texas Natural Resources Conservation Commission designating a portion of the Trinity Aquifer within Bexar County as a Priority Groundwater Management Area (PGMA). The Trinity Glen Rose Groundwater Conservation District is the governing body of only that portion of the Trinity Aquifer that is located in northern Bexar County. This Aquifer is considered very important to the State of Texas and subject to the provisions in Chapter 35 of the Texas Water Code. The TNRCC designated this area a PGMA in January 2001 and created the TGRGCD in order that appropriate groundwater management techniques and strategies could be implemented at the local level to address groundwater issues or problems within the District. A PGMA designation is given to an area “that is experiencing, or is expected to experience critical groundwater problems.” One of the primary reasons that a PGMA was designated in this area is the explosive growth in North Bexar and surrounding counties. The duty of the TGR Board members will be to ensure that the water in the aquifer is managed in a reasoned and balanced manner to allow for growth in the area, while still preserving the ability of residents or their water suppliers to draw water for their families. The District will conduct administrative and technical activities and programs to achieve these purposes. The District will collect and archive water well and aquifer data, regulate water well drilling and production from non-exempt wells, promote the capping or plugging of abandoned wells, provide information and educational material to local property owners, interact with other governmental or organizational entities, and incorporate other groundwater-related activities that may help meet the purposes of the District. Enacting 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.

Go Gardening Show - Season 5 - Episode 7 Welcome to Season 5 of the Go Gardening Show! This month's Go Gardening Show brings to light one of those famous GG Hidden Gems and then a landscape that has been "in the works" for several decades. First up...if you've never heard of Charis Park, then hopefully this first segment will shed some colorful light on this great little park. Situated in the Alamo Heights area, it is a vision brought to life by a local church. The nature park was once a mostly-paved parking lot for the church, but now with some creative landscape design, Charis Park is hub for community gathering and peaceful meditation among some vibrant native plant and pollinator areas, repurposed construction materials and playscapes for children. Next, the Go Gardening crew visited a long-time resident of San Antonio and her journey to create a natural park-like setting in her own backyard. She took her time and achieved that goal doing most of the work herself. While the landscape was both wonderful to tour, the story behind its development made our visit that much more enjoyable. Go Gardening's mission is to help people conserve water in the Edwards and Trinity Aquifers by teaching homeowners how to convert turfgrass areas to low-to-no water use landscapes featuring native plants.
