Water wells in the upper Trinity (Paluxy and Glen Rose), Burnet County, Texas

Home water wells that draw from the upper Trinity (Paluxy and Glen Rose) in Burnet County, Texas vary a lot in depth: the middle half are 195 to 530 feet deep (median 365 ft, 36 wells reported since 2001), so look at the wells closest to the tract. It is a minor layer here: just 1% of the 1,871 wells the state's model covers; the main one is the lower Trinity (Twin Mountains and Travis Peak) (72%). They are about as deep as the county's median well (350 ft). Estimated cost of a complete well at the median depth: $11,500 to $28,500.

Which layer Burnet County wells draw from

County home wells covered by the Northern Trinity and Woodbine model (in the last 10 years).

What this layer is

This group is the upper half of the Trinity in North and Central Texas: the Paluxy sand on top and the Glen Rose limestone and marl under it. The state's model draws them as two layers, but our check against the state's own aquifer codes shows the method cannot tell them apart reliably, so this atlas reports them together. North and west of Fort Worth the limestone gives way to sand and both become the upper part of the undivided Antlers Formation.

Depth over time

There are not enough wells in both 2003 to 2007 and 2021 to 2025 (at least 30 in each) to say with confidence whether wells in this layer in Burnet County are getting deeper. For reference, the median was 495 feet in 2016 to 2020 (10 wells) and 540 feet in 2021 to 2025 (11 wells).

Common questions

How deep is a well in the upper Trinity (Paluxy and Glen Rose) in Burnet County?

Home water wells that draw from the upper Trinity (Paluxy and Glen Rose) in Burnet County, Texas vary a lot in depth: the middle half are 195 to 530 feet deep (median 365 ft, 36 wells reported since 2001), so look at the wells closest to the tract.

How many Burnet County wells draw from this layer?

It is a minor layer here: just 1% of the 1,871 wells the state's model covers; the main one is the lower Trinity (Twin Mountains and Travis Peak) (72%). Only 58% of these wells have the water-bearing interval on their report (reports before about 2012 rarely do). For the others we use the bottom of the hole, which tends to read one layer deeper than where the water actually comes from.

How deep does the water stand?

When the wells were finished, the water stood a median 188 feet below the surface (26 wells).

What a well costs here

At the median depth for this layer in Burnet County (365 feet), a complete home well would cost roughly $11,500 to $28,500: $25 to $60 per foot for drilling, casing and seal, plus $2,500 to $6,500 for the pump, pressure tank, controls and hookup at the well. Across the whole middle half of depths (195 to 530 feet) the range runs from $7,500 to $38,500. This is TerraFunded's estimate from published Texas prices, not a quote, and it leaves out trenching and the line to the house. Get prices from at least two licensed drillers.

How these numbers are made

We count new and replacement domestic (home) wells with a valid depth on their report. We use the last 10 years when there are at least 30 wells; otherwise all since 2001. The median is the middle well and the middle half runs from the 25th to the 75th percentile.

To tell which layer a well draws from, we take the ground elevation at its location, subtract the depth of the interval where water enters (or the bottom of the hole when the report does not give one) and see which layer of the state's model that point falls in.

Only 58% of these wells have the water-bearing interval on their report (reports before about 2012 rarely do). For the others we use the bottom of the hole, which tends to read one layer deeper than where the water actually comes from.

How well it works: In 7,977 wells in the area of the state's Northern Trinity and Woodbine model (North and Central Texas) where the State of Texas recorded the aquifer, our estimate of the formation the well draws from names the same layer of the state's model in about 74% of them, and that layer or the one next to it in at least 95%; among the 3,130 of those wells that the state places in a Trinity layer (Paluxy to Hosston) it is about 56%.

  • The layers come from the Texas Water Development Board's Northern Trinity and Woodbine model, with quarter mile cells, summarized here to about 1.3 miles. It is a regional model, not a survey of any lot: between one model point and the next, the real depth of each layer can differ.
  • In this model every layer is at least 30 feet thick, even where the real rock is thinner or missing. Thin layers and the edges of the model are approximate.
  • Inside the Trinity this atlas does not name single model layers: it groups the Paluxy and Glen Rose (upper Trinity) and groups the Hensell, Pearsall and Hosston (lower Trinity, Twin Mountains and Travis Peak), because the check against the state's codes shows the method cannot separate them reliably.
  • "Near or below the base of the Trinity" means the well reaches the bottom of the model or passes it, often by tens of feet. Older rock that the model does not include may lie there.
  • We never use the model's water levels. The water level on this page is the one each driller measured when the well was finished.

These are depths of real wells drilled nearby, not a promise about any property. Groundwater can change over short distances and with drought. A licensed water well driller can tell you what to expect on a specific tract.
