Watersaver Landscape Tour Happening Oct. 24

The 2020 Watersaver Landscape Tour is scheduled for Saturday, October 24 at 10 a.m. This year’s tour will be held online given the pandemic has not completely subsided. But, that hasn’t dampened the enthusiasm of sponsors Gardening Volunteers of South Texas (GVST), San Antonio Water System (SAWS) and Trinity Glen Rose Groundwater Conservation District (TGR) to bring you an inside look at some water-saving landscapes in San Antonio.

For each featured home, you will see a short video that contains an interview with the homeowner and several colorful photos from the landscape. Horticultural experts Calvin Finch, Jerry Parsons and Mark Peterson will be on hand to describe the photos and explain how you can create your own personal oasis using water-saving native plants. Viewers will also be able to download a plant list from each yard that will be greatly helpful as each video plays.

In addition to the insightful landscape information, there will be some great prizes given away to some lucky webinar attendees. You can sign up today! Just click on this link and register.

If you want a nice warmup for the Watersaver Landscape Tour, you can sign up for the Gardening Volunteers Landscape Design School scheduled for Oct 19. You can sign up for the design school at this link.

“Learn and Live” at Stone Oak Park

Third in a series of six articles.

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.

​​TGR Board Election Scheduled for Nov. 3

The Trinity Glen Rose Groundwater Conservation District (TGR) board of directors had to cancel its May board member election given the issues with COVID-19 virus. The District will be holding that election for its one board vacancy during the November 3, 2020 elections.

Time to Have your Sprinkler System Checked

July through September is typically the hottest and driest stretch of weather we see in South Texas each year. Any by now you know that means that your water conservation knowledge and skills should be on high alert. Because landscape watering can account for up to 60 percent of the city’s water use during this time of year, the Trinity Glen Rose District always like to remind homeowners and business owners to have their sprinkler systems inspected before the systems are turned on for regular use. Wasted water cannot be retrieved, so you only get one chance to efficiently use the water provided by the city’s water resources such as the Trinity and Edwards Aquifers.

The quickest do-it-yourself way to check your system is to start it up and then inspect each of the sprinkler heads in all of the system’s zones. Look for broken heads or heads that have sunken below ground. Then make sure that the heads are not watering the streets and sidewalks. Then you can observe whether there is adequate water pressure feeding each sprinkler head. A broken pipe or sprinkler head can drain away pressure and waste significant amounts of water.

Also, if you have been slowly and steadily replacing high water use plants with native low water use plants, you might make sure that your sprinkler system either does not water areas with native plants or waters only a little.

Here is some great news for you. The Trinity Glen Rose District and San Antonio Water System have teamed up over the last few years to offer free irrigation system consultation programs. In fact, TGR will give you a $50 coupon to have the consultation done. Just go to for more information.

TGR Addressing COVID-19 Virus Health Safety Concerns

The Trinity Glen Rose Groundwater Conservation District (TGR) staff relocated to a new office in Helotes just before the March COVID-19 virus pandemic declarations by the State of Texas and City of San Antonio. 

As of July 6, District staff alternate days throughout the week to minimize risk to constituents, staff and the general public by reducing group interactions. In the event an in-person appointment is needed, we will make every effort to accommodate. We will conduct a temperature screening prior to entering the office and require that all individuals present wear a mask and maintain 6' social distancing at all times. We will continue to monitor public health reports and recommendations and will continue to make future decisions based on the guidance provided by public health officials.

If you need assistance, you may call the office at 210-698-1155 and leave a message or you may call 210-219–5555 to contact someone directly.

TGR Publishes 2019 Annual Report 

The Trinity Glen Rose Groundwater Conservation District (TGR) just published its 2019 Annual Report. The TGR board reviewed the report in early March and approved the document for publication at its March meeting.

The 2019 Annual Report provides good background on the:

  •  purpose of the district

  •  district goals

  •  current leadership

  •  well monitoring work

  •  financial position, and

  •  community outreach programs

This year, the District included two charts which outline TGR’s involvement in regional GMA-9 joint water planning efforts required by the State of Texas. The charts provide a 10-year history of water use in the region and how that compares to the region’s goals for water production from the Trinity Aquifer. Those goals are known as “desired future conditions.”
