New household wells in Parker County have a median depth of 240 ft, and the middle half fall between 200 and 300 ft, based on 4,746 Texas Water Development Board driller reports since January 2021. Water typically stands about 110 ft down. East-side wells run deeper, with Aledo's median at 320 ft, while Peaster, Poolville and Brock cluster at 215–220 ft.
Water Well Drilling Weatherford pulled every new household well report filed in Parker County and its neighbors to answer this properly. How deep are water wells in Parker County? depends on which part of the county, and the state’s own records make that easy to show.
Depth by town
New household wells within about five miles of each town (six for Weatherford, Granbury and Mineral Wells), January 2021 to September 2026:

| Weatherford | 590 | 240 ft | 200–340 ft | ~110 ft |
| Aledo | 357 | 320 ft | 252–360 ft | ~176 ft |
| Springtown | 178 | 240 ft | 200–380 ft | ~100 ft |
| Azle | 324 | 220 ft | 200–240 ft | ~80 ft |
| Peaster | 924 | 220 ft | 200–240 ft | ~90 ft |
| Poolville | 685 | 215 ft | 200–220 ft | ~80 ft |
| Brock | 600 | 220 ft | 200–260 ft | ~125 ft |
| Millsap | 110 | 200 ft | 160–240 ft | too few readings |
| Mineral Wells | 185 | 200 ft | 200–260 ft | ~85 ft |
| Granbury (Hood Co.) | 157 | 360 ft | 200–420 ft | ~260 ft |
| Hood County (all) | 642 | 360 ft | 220–400 ft | ~240 ft |
Why depth changes across the county
The Upper Trinity district’s management plan describes four Trinity aquifer layers under Parker County:
- Paluxy Sand: fine sand; small to moderate yields.
- Glen Rose Formation: mostly limestone; small, localized yields.
- Twin Mountains Formation: coarser sand with a massive lower section; moderate to large yields. Wells are usually completed in its lower part.
- Antlers Formation: where the Glen Rose thins out to the north (around central Wise County), the Paluxy and Twin Mountains merge into the Antlers.
In the east, younger Fredericksburg and Washita limestones overlie the Trinity. That’s why Aledo wells run deeper and water stands lower. In the far west, the Trinity is absent and wells tap the Cross Timbers Aquifer, older rock where water sits in fractures and sandstone lenses. There, depths are modest but yields vary, as around Millsap and Mineral Wells. Hood County wells often go to the deep Twin Mountains, and 41% of new wells around Granbury went 400 ft or deeper.
Are wells getting deeper?
In some places. Around Aledo, the median new well went from about 240 ft in 2011–2013 to 320–350 ft since 2018. Around Granbury, it rose from about 320 ft in 2006–2015 to 360–400 ft since. Around Weatherford, Azle, Peaster and Poolville, medians have barely moved in 20 years. See is my well going dry? for what the water-level trends show.
Depth and cost
Depth drives most of a new well’s price. Drilling and casing typically run $30–$45 per foot, and deeper wells need the pump set lower too. See water well drilling cost in Weatherford or try the cost calculator.
Bottom line
Plan on about 240 ft for a typical Parker County household well, 300+ ft on the east side and in Hood County, and 200–220 ft in the north and west. The best estimate for a specific lot comes from the state reports for wells nearest it.
