Which formation do wells in Umbarger draw from?

Most draw from the Ogallala Aquifer (67%), and 33% end at or just below the base of the Ogallala, in the top of the Dockum, according to the state's High Plains Aquifer System model (TWDB). Read that as the base of the Ogallala or the top of the Dockum, not a certainty: where our method names the Dockum, the state's own record agrees only about 33% of the time (61% for wells with a screened interval), and most of the others are recorded as Ogallala wells.

The bottom of the hole tells a different story: 85% end at or just below the base of the Ogallala, in the top of the Dockum, although only 33% take their water from there. Many drillers go past the producing layer to leave a reserve.

For 88% of these wells the report says where the water enters and we use the middle of that interval; for the rest we use the bottom of the hole, which tends to read one layer too deep.

What a well costs in Umbarger

At the median depth for Umbarger (240 feet), a complete home well would cost roughly $8,500 to $21,000: $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 (200 to 245 feet) the range runs from $7,500 to $21,000. 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 Umbarger, Texas?

Home water wells in and around Umbarger, Texas are typically 200 to 245 feet deep (median 240 ft, 33 wells reported since 2001). One in ten goes past 278 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 Umbarger draw from?

Most draw from the Ogallala Aquifer (67%), and 33% end at or just below the base of the Ogallala, in the top of the Dockum, according to the state's High Plains Aquifer System model (TWDB). Read that as the base of the Ogallala or the top of the Dockum, not a certainty: where our method names the Dockum, the state's own record agrees only about 33% of the time (61% for wells with a screened interval), and most of the others are recorded as Ogallala wells. This is an estimate from the state's regional model, not a survey of the lot.

How much does a water well cost in Umbarger?

At the median depth (240 feet), a complete well would cost roughly $8,500 to $21,000, 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 Umbarger?

When the wells were finished, the water stood a median 142 feet below the surface (20 wells). The level moves with drought and from one well to the next.

Do I need a permit to drill a well in Umbarger?

Umbarger is inside the High Plains Underground Water Conservation District No. 1. 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.

For 88% of these wells the report says where the water enters and we use the middle of that interval; for the rest we use the bottom of the hole, which tends to read one layer too deep.

How well it works: In 22,814 wells in the Texas part of the state's High Plains Aquifer System model (the Panhandle, the South Plains and the Permian Basin) where the State of Texas recorded the aquifer, the formation our method says the well draws from (as grouped on these pages) is the one the state recorded in about 75% of them; when it names the Dockum (4,542 wells), the state's record agrees only about 33% of the time, and most of the others are recorded as Ogallala wells.

  • The layers come from the Texas Water Development Board's High Plains Aquifer System model, with half mile cells, read here on a grid of about 1.2 by 1.4 miles. It is a regional model, not a survey of any lot.
  • The state's model has half mile cells; we read it on a grid of about 1.2 by 1.4 miles, Texas part only. Layers from version 1.01 (2015); the 2025 extension (1.02) did not change them. It is not a survey of any lot, so we give ranges.
  • Figures go by four groups: Ogallala; Pecos Valley; Edwards-Trinity and Rita Blanca (Cretaceous rock under the Ogallala; the Rita Blanca alone matched the state 19%); Dockum (upper and lower together: the state's codes almost never say which). The Edwards-Trinity group joins three aquifers in different places (High Plains around Lubbock, Plateau around Midland and Odessa, Rita Blanca in Dallam and Hartley): county and place pages name the local one where they can.
  • Dockum: when our method names the Dockum, the state's record agrees only 33% of the time over all years (61% for wells with a screened interval, which is 93% of home wells of the last 10 years); most of the rest are recorded as Ogallala wells. The median well we put in the Dockum ends about 18 ft under the base of the Ogallala as the model draws it. So these pages say "at or just below the base of the Ogallala, in the top of the Dockum", never a certain formation. The state's own 2025 report on this model says depth alone overstates the upper Dockum.
  • "Near or below the base" means the well ends near or below the base of the Dockum, or of the Ogallala where there is no Dockum (Permian red beds; Gray, Carson, Donley, Moore and north Potter counties). Half of these wells end within about 51 ft of the base, and the state usually records them as Ogallala or Dockum wells. That is not an error: the model simply ends there.
  • For old wells without a screened interval (bottom of the hole) the method is only a little better than always saying Ogallala (65% against 58%); with an interval it is 89% against 80%. Figures over all years carry that weakness; last 10 years figures rest almost entirely on intervals.
  • 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.
