Water wells in the Woodbine Aquifer, Cooke County, Texas

Only 26 home water wells that draw from the Woodbine Aquifer in Cooke County, Texas have been reported since 2001, so treat this as a rough guide: the middle half are 116 to 152 feet deep (median 132 ft). It is a minor layer here: just 2% of the 639 wells the state's model covers; the main one is the upper Trinity (Paluxy and Glen Rose) (62%). They run about 368 feet shallower than the county's median well (500 ft). Estimated cost of a complete well at the median depth: $6,000 to $14,500.

This page is based on fewer than 30 wells, so it is kept out of search engines until more reports come in. Treat every figure as a rough guide.

Which layer Cooke County wells draw from

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

What this layer is

The Woodbine is a sandstone with shale beds (the Lewisville and Dexter formations, and the Pepper Shale to the south) that sits above the Trinity across North Texas. The state lists it as a minor aquifer.

Common questions

How deep is a well in the Woodbine Aquifer in Cooke County?

Only 26 home water wells that draw from the Woodbine Aquifer in Cooke County, Texas have been reported since 2001, so treat this as a rough guide: the middle half are 116 to 152 feet deep (median 132 ft).

How many Cooke County wells draw from this layer?

It is a minor layer here: just 2% of the 639 wells the state's model covers; the main one is the upper Trinity (Paluxy and Glen Rose) (62%). Only 42% 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 55 feet below the surface (20 wells), well above the bottom: the typical well holds about 77 feet of water.

What a well costs here

At the median depth for this layer in Cooke County (132 feet), a complete home well would cost roughly $6,000 to $14,500: $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 (116 to 152 feet) the range runs from $5,500 to $15,500. 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 42% 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.
  • In this area, north and west of Fort Worth, the state maps the Trinity as one undivided unit, the Antlers Formation. The model cuts it into layers by depth; the split between upper and lower Trinity shown here is approximate, and the depth ranges are the solid part.
  • "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.
