Water wells in the Wintergarden Groundwater Conservation District

Q: What does a groundwater conservation district do?

In Texas, districts are the local authority over groundwater: they can require registration or permits for new wells, set spacing from other wells and property lines, and limit pumping. Each district writes its own rules, so ask the Wintergarden Groundwater Conservation District before drilling inside it.

Home water wells inside the Wintergarden Groundwater Conservation District (La Salle, Dimmit and Zavala counties, Texas) are typically 360 to 575 feet deep (median 435 ft, 159 wells drilled in the last 10 years). Drillers reported 14 new home wells in 2025, less than half the peak of 58 in 2006. Estimated cost of a complete well at the median depth: $13,500 to $32,500.

Updated every day from Texas Water Development Board driller reports. Last update: November 11, 2026, using the state file of November 10, 2026.

Depth over time

New home wells in the district are deeper than 20 years ago: the median went from 360 feet (2003 to 2007) to 480 feet (2021 to 2025), 33% more. Deeper wells do not always mean the water dropped: a driller may be going for another layer, better water or more reserve.

Common questions

How deep are wells in the Wintergarden GCD?

What does a groundwater conservation district do?

In Texas, districts are the local authority over groundwater: they can require registration or permits for new wells, set spacing from other wells and property lines, and limit pumping. Each district writes its own rules, so ask the Wintergarden Groundwater Conservation District before drilling inside it.

What a well costs here

At the median depth for the district (435 feet), a complete home well would cost roughly $13,500 to $32,500: $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 (360 to 575 feet) the range runs from $11,500 to $41,000. 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 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.

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.
