Which formation do wells in Bear Creek draw from?

No single layer dominates: 51% are completed in the Middle Trinity and 49% in the Lower Trinity, according to the state's Hill Country Trinity model (TWDB).

The bottom of the hole tells a different story: 51% reach the Lower Trinity, although only 49% take their water from it. Many drillers go past the producing layer to leave a reserve.

Layer (state's model)ShareWellsTypical depth (ft)
Middle Trinity51%40550–630
Lower Trinity49%39750–888

Only 32% 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.

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 and around Bear Creek are getting deeper. For reference, the median was 730 feet in 2001 to 2005 (21 wells) and 625 feet in 2021 to 2025 (14 wells).

What a well costs in Bear Creek

At the median depth for Bear Creek (650 feet), a complete home well would cost roughly $19,000 to $45,500: $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 (590 to 812 feet) the range runs from $17,500 to $55,000. 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.

Common questions

How deep do you have to drill a well in Bear Creek, Texas?

Home water wells in and around Bear Creek, Texas are typically 590 to 812 feet deep (median 650 ft, 92 wells reported since 2001). One in ten goes past 894 feet. The depth a given tract needs depends on where it sits and what layers the driller hits.

What aquifer or formation do wells in Bear Creek draw from?

No single layer dominates: 51% are completed in the Middle Trinity and 49% in the Lower Trinity, according to the state's Hill Country Trinity model (TWDB). This is an estimate from the state's regional model, not a survey of the lot.

How much does a water well cost in Bear Creek?

At the median depth (650 feet), a complete well would cost roughly $19,000 to $45,500, by TerraFunded's estimate from published Texas driller prices. The real price comes from a licensed driller's quote.

How deep is the water in Bear Creek?

When the wells were finished, the water stood a median 338 feet below the surface (72 wells). The level moves with drought and from one well to the next.

Do I need a permit to drill a well in Bear Creek?

Bear Creek is inside the Hays Trinity Groundwater Conservation District. Groundwater conservation districts in Texas can require registering or permitting a new well, keeping set distances from property lines and other wells, and paying fees. Rules differ from district to district: ask the district before drilling.

How these numbers are made

We count new and replacement domestic (home) wells whose coordinates fall inside the place boundary or within 2 miles of it. 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 32% 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 2,665 wells in the Texas Hill Country 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 76% of them, and that layer or the one next to it in at least 98%.

  • The layers come from the Texas Water Development Board's Hill Country Trinity model, with 1 mile cells. 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.
  • "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.
