Water wells in younger formations above the Woodbine, Red River County, Texas

Home water wells completed in younger formations above the Woodbine in Red River County, Texas vary a lot in depth: the middle half are 75 to 411 feet deep (median 100 ft, 65 wells drilled in the last 10 years), so look at the wells closest to the tract. It is the county's main layer: 92% of the 71 wells the state's model covers. They run about 10 feet deeper than the county's median well (90 ft). Estimated cost of a complete well at the median depth: $5,000 to $12,500.

When the wells were finished, the water stood a median 26 feet below the surface (50 wells), well above the bottom: the typical well holds about 74 feet of water.

What this layer is

The state's Northern Trinity and Woodbine model treats everything above the Woodbine as a single layer: the Eagle Ford, Austin, Taylor and Navarro groups (mostly shale, chalk and marl) plus younger sands and river deposits where they exist. It is a catch-all, not one rock. In counties east and south of the Trinity outcrop, a home well in this layer is usually drawing from a younger local sand that this model does not separate.

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 Red River County are getting deeper. For reference, the median was 175 feet in 2001 to 2005 (17 wells) and 88 feet in 2021 to 2025 (44 wells).

Common questions

How deep is a well in younger formations above the Woodbine in Red River County?

Home water wells completed in younger formations above the Woodbine in Red River County, Texas vary a lot in depth: the middle half are 75 to 411 feet deep (median 100 ft, 65 wells drilled in the last 10 years), so look at the wells closest to the tract.

How many Red River County wells draw from this layer?

It is the county's main layer: 92% of the 71 wells the state's model covers. For 94% of these wells the report says where the water enters (the screen or the open hole), and we use the middle of that interval.

How deep does the water stand?

When the wells were finished, the water stood a median 26 feet below the surface (50 wells), well above the bottom: the typical well holds about 74 feet of water.

What a well costs here

At the median depth for this layer in Red River County (100 feet), a complete home well would cost roughly $5,000 to $12,500: $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 (75 to 411 feet) the range runs from $4,500 to $31,000. 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.

For 94% of these wells the report says where the water enters (the screen or the open hole), and we use the middle of that interval.

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.
