Water wells in the Lone Wolf Groundwater Conservation District

Common questions

What a well costs here

At the median depth for the district (160 feet), a complete home well would cost roughly $6,500 to $16,000: $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 (140 to 220 feet) the range runs from $6,000 to $19,500. 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 whose coordinates fall inside the district boundary. 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 98% 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 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.
