TGR District Website Gets a New Look, Navigation

The Trinity Glen Rose District recently updated its website to feature a new look and easier page navigation. District staff went through each page of the previous website and updated all information pertinent to the page’s topics. Additionally, content was reorganized according to how people are using the site.

“We have tried to refresh the look of our website every few years and that always give us the opportunity to go through the content in detail,” said TGR General Manager George Wissmann. “This year we opted to create more pages and drop down menus so information could be found quickly. That will reduce viewers having to scroll through pages to find what they’re looking for. Additionally, we wanted to feature some of the great photos taken for our last pollution prevention campaign. So, not only is the new site filled with very important and helpful information about the Trinity Aquifer and the TGR District, it is visually pleasing as well. Check out the new website at: www.TrinityGlenRose.com.

Fall Landscape Maintenance, Planting Check List

The San Antonio Botanical Gardens has a great set of things to do for your landscape this fall. Here are 15 items to consider for keeping your landscape in great shape this fall and in preparation for next spring.

  • To minimize the likelihood of weeds this fall, do not allow weeds to go to seed.

  • Plant shade trees now to take advantage of the mild fall and winter weather for root growth.

  • Prepare beds to plant cool season flowers. Add compost as need to your flowerbeds.

  • Deadhead flowering plants to stimulate more blooms.

  • This is the last time to fertilize roses for the winter months. Wait until January/February to fertilize again.

  • With the mild weather, it is a perfect time to plant landscapes. The cooling temperatures allow for more root growth, which will establish the plant before winter cold snaps.

  • Take advantage of the weather and dig, divide and plant your spring/summer blooming perennials.

  • Begin to back off on watering. With the cooler temperatures, soils stay moist longer than they did this summer. You do not want to overwater your plants.

  • Mulch all new plantings to reduce weeds, maintain soil moisture and regular soil temperatures.

  • This will be the last time to do any pruning on your rose bushes until February.

  • Sow bluebonnets and other wildflowers.

  • Make preparation to protect tropical plants or move them to a greenhouse.

  • Prepare exposed pipes for winter.

  • After last use of mower or other power equipment, make the machines ready for winter storage. Don’t leave gasoline in the machine over winter

  • Start thinking about purchasing fall planting/spring blooming bulbs. Don’t plant until all hot weather is over.

  • Prune trees when they are dormant.

Time to Have your Sprinkler System Checked
$50 Coupon for irrigation consult v2-2.j

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 www.TrinityGlenRose.com/conservation 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 2020 Annual Report 

The Trinity Glen Rose Groundwater Conservation District (TGR) just published its 2020 Annual Report. The TGR board reviewed the report in early March and approved the document for publication at its March meeting.

The 2020 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.”
