Is the well water in Wise County salty or brackish?

Mostly fresh, with two things to watch. Wise County's Trinity (the Antlers and Twin Mountains sand) is generally fresh, but the Texas Water Development Board found scattered slightly-salty occurrences in the deep basal Trinity sand, and the older Cross Timbers units in western Wise County (west of Bridgeport) can be limited and mineralized. A full water test, including total dissolved solids, is worth budgeting where you are drilling deep or in the far west.

Which GCD governs water wells in Wise County?

Wise County is within the Upper Trinity Groundwater Conservation District (Upper Trinity GCD), which also covers Hood, Montague, and Parker counties. The Upper Trinity GCD operates under Texas Water Code Chapter 36 and manages the Trinity aquifer system, including the Antlers Formation in central and northern Wise County where the Glen Rose Limestone is absent.

Do I need a permit before drilling a well in Wise County?

Yes. The Upper Trinity GCD requires a pre-drilling permit before any new well is constructed in Wise County, including residential domestic and livestock wells. Your TDLR-licensed driller will submit the permit application on your behalf. Do not begin drilling before written permit approval is in hand.

What counts as an exempt well under UTGCD Rule 3.1?

Under UTGCD Rule 3.1, wells used solely for domestic use, livestock, poultry, or agriculture are exempt from production limits without a volume cap. Non-domestic, non-livestock, non-poultry, non-agricultural wells operated by anyone other than a retail public utility are exempt only if pump capacity is 17.36 gpm or less. The 25,000 gallons per day default rule from Texas Water Code Section 36.117 is not the operative UTGCD test. Registration and spacing rules still apply to exempt wells.

How deep are wells typically drilled in Wise County?

Depths vary substantially across the county. In central and northern Wise County (Decatur, Paradise, Bridgeport area), where the Glen Rose Limestone is absent, wells typically target the Antlers Formation. In southern Wise County (Boyd, Rhome, and areas closer to Parker), the Paluxy, Glen Rose, and Twin Mountains stack remains distinguishable. In west-central Wise County (west of Bridgeport), the Trinity is thin or absent and some properties complete in older Cross Timbers and Paleozoic units, often with limited yield and mineralization. Confirm with the driller for your specific parcel.

Does my property qualify for the Springtown city services if it's near the Parker/Wise county line?

Springtown straddles the Parker/Wise county line. Both sides of the line are within Upper Trinity GCD, so the same UTGCD rules apply either way. The Upper Trinity GCD district office is at 1859 W. Hwy. 199 in Springtown. That said, county-level matters outside GCD jurisdiction — appraisal, septic permitting, road maintenance — depend on which county your parcel actually sits in. Confirm the parcel's county before assuming Wise or Parker rules apply to anything beyond the GCD.

What water quality issues should Wise County well owners anticipate?

Iron and manganese are common in Antlers and Paluxy outcrop areas. Hardness is common throughout the Trinity. In west-central Wise County, Cross Timbers wells can be elevated in total dissolved solids, sulfate, and chloride. Twin Mountains water tends to be fresh to slightly saline. After drilling, test for coliform bacteria, nitrates, iron, manganese, hardness, sulfate, pH, and total dissolved solids before relying on the well or buying treatment equipment.

Planning a well in Wise County?

Local requirements depend on your property, the Upper Trinity GCD’s rules, and what you intend to use the well for. We can help you understand the practical next steps. We do not provide legal advice.

Wise County sits along the western Cross Timbers, north of Parker County and east of Jack County. Whether you are drilling a new home well, a ranch supply, or replacing an existing well, your regulatory starting point is the Upper Trinity Groundwater Conservation District.

Which GCD Governs Wise County?

Wise County is fully within the Upper Trinity Groundwater Conservation District (Upper Trinity GCD), often shortened to UTGCD. The district also covers Hood, Montague, and Parker counties — all four counties operate under the same UTGCD rule set. The district was created by the 80th Texas Legislature and confirmed by voters in 2007, and operates under Texas Water Code Chapter 36. The district website is uppertrinitygcd.com, and the district office is at 1859 W. Hwy. 199 in Springtown.

UTGCD manages the Trinity aquifer system across the four counties. In Wise County specifically, that includes the Antlers Formation in central and northern Wise County (where the Glen Rose Limestone is absent and the Paluxy and Twin Mountains coalesce), the full Paluxy / Glen Rose / Twin Mountains stack in southern Wise County, and the Cross Timbers minor aquifer in the west-central part of the county.

Step-by-Step: Drilling a Well in Wise County

Step	Action	Who Is Responsible
1	Hire a TDLR-licensed water well driller	Property owner
2	Submit pre-drilling permit application to Upper Trinity GCD	Licensed driller
3	Receive UTGCD permit approval — drilling may not begin before this	Upper Trinity GCD
4	Drill the well in compliance with permit conditions and UTGCD spacing rules	Licensed driller
5	File the State of Texas Well Report with TDLR within 60 days of completion	Licensed driller
6	Test water quality before relying on the well	Property owner

The permit step applies to all new wells in Wise County — including exempt domestic and livestock wells. Exemption from production limits is not exemption from permitting.

Exempt vs. Non-Exempt Wells Under UTGCD Rule 3.1

The Upper Trinity GCD uses a use-category structure for exemption rather than the 25,000 gallons per day default that appears in many other parts of Texas. Under UTGCD Rule 3.1:

Wells used solely for domestic use, livestock, poultry, or agriculture are exempt from production limits with no volume cap.
Wells used for other purposes (commercial, industrial, irrigation, public supply) by anyone other than a retail public utility are exempt only if the pump’s capacity is 17.36 gallons per minute or less.
Leachate wells, monitoring wells, and closed-loop geothermal wells are also exempt.

Even exempt wells require UTGCD registration and pre-drilling permitting, and must meet UTGCD’s spacing rules. Non-exempt wells require meters and annual production reporting.

A note on oil and gas: wells used solely to supply rigs actively drilling or exploring oil and gas wells permitted by the Railroad Commission are exempt. Wells used to supply water for hydraulic fracturing are not exempt.

UTGCD Spacing Rules (Rule 4.3)

UTGCD’s spacing rules scale with pump capacity. Minimum tract size for a new well is 2 acres. Spacing from existing wells and from property lines increases as the pump’s capacity rating goes up:

Pump Capacity Class	Spacing from Other Wells	Spacing from Property Line
Less than 17.36 gpm	150 ft	50 ft
17.36 to 30 gpm	500 ft	150 ft
30 to 50 gpm	1,000 ft	250 ft
50 to 80 gpm	1,750 ft	500 ft
80 to 100 gpm	2,500 ft	750 ft
Over 100 gpm	3,250 ft	1,000 ft

Your driller will design the well to fit the spacing class that matches your intended pump.

Reporting and Fees

Non-exempt wells in UTGCD must be metered and must report production annually to the district. Exempt wells (domestic, livestock, poultry, agricultural, and small-capacity non-domestic) do not require metering or production reporting. Non-exempt wells are also subject to UTGCD production fees and permit-related fees. The Upper Trinity GCD Board sets the fee schedule annually; the current schedule is published on the UTGCD Forms & Fees page at uppertrinitygcd.com.

Since January 1, 2024, Senate Bill 2440 also requires a Texas-licensed engineer or geoscientist certification of adequate groundwater availability for any subdivision plat application whose water-supply source is groundwater. This applies inside UTGCD per the district’s Groundwater Availability Certification page.

Working With a Licensed Driller

All water wells in Texas must be drilled by a contractor holding a valid TDLR Water Well Driller license. In Wise County, experience with the Trinity / Antlers transition matters as much as licensure — a driller who knows the central-Wise Antlers, the southern-Wise Paluxy/Glen Rose/Twin Mountains stack, and the west-central Cross Timbers will plan your well around the formation pattern actually under your property, not a generic countywide model.

An experienced driller will review TWDB well logs for nearby properties, talk through likely depth and yield, and handle the UTGCD permit application from start to finish.

DFW Well Service (TDLR License #61234 DKMPW) is available to drill throughout Wise County — from Decatur and Bridgeport to Boyd, Paradise, and Rhome. Call us at (940) 536-8560 to discuss your property and get a site-specific estimate.

Wise County rewards drillers and property owners who plan around the actual geology of their parcel. Confirm your property is in the Upper Trinity GCD service area, talk with a driller who has worked the part of the county you are in, and budget for the formation pattern you will encounter — not the one a neighbor twenty miles away encountered.
