Well Water in Randall County, Texas

Step one: is the parcel actually inside the district?

The High Plains Underground Water Conservation District No. 1 (HPWD), created in 1951 and one of the oldest groundwater districts in Texas, covers eight counties in full -- Bailey, Cochran, Hale, Lamb, Lubbock, Lynn, Parmer, and Swisher. Randall County is not one of them. HPWD's own published materials on its service territory describe only a small portion of Randall County (along with similarly small portions of Armstrong and Potter Counties) as falling inside Groundwater Management Area 1, the joint planning area HPWD participates in. That phrasing matters: it means a meaningful share of Randall County land sits entirely outside HPWD's regulatory boundary, subject only to Texas's general rule of capture with no local district permitting a well, setting spacing rules, or capping production -- while another part of the county is genuinely inside HPWD and subject to its full rule set. There is no substitute here for checking a specific parcel's location against HPWD's actual boundary map (or contacting the district directly) before assuming either situation applies.

Where HPWD does apply: permits, exemptions, and an enforced production cap

Where a parcel does fall inside HPWD's boundary, state law sets a baseline exemption: a private domestic or livestock well using less than 25,000 gallons of water per day generally does not require a district permit, while an irrigation well using more than that threshold does. Beyond that baseline exemption, HPWD has its own rule establishing an "allowable production rate" for wells subject to its permitting -- and the district has made clear that pumping in excess of that allowable rate is treated as a rule violation, not simply a soft guideline. That combination (a household-use exemption, but real enforced limits above it) is worth understanding clearly before assuming an exempt small well and a larger irrigation or commercial well would be treated the same way inside the district.

• Confirm directly with HPWD whether a specific Randall County parcel falls inside its boundary before assuming either "no district" or "full HPWD rules" apply.
• If a well would be used for irrigation or another use likely to exceed 25,000 gallons/day, budget time for HPWD's permitting process rather than assuming exempt status.

Two aquifers, two different pictures

Randall County's groundwater has historically been described around the Ogallala Aquifer, the massive High Plains aquifer whose regional depletion story -- decades of pumping exceeding natural recharge -- is well documented in state water-planning literature going back decades. That regional narrative is real, but it is not the whole Randall County picture. A more specific, more recent data point complicates it: roughly half of the private wells drilled in Randall County instead draw from the deeper Dockum Aquifer rather than the Ogallala. And an August 2025 report on an HPWD update specifically addressing water use in Randall County found that the county has not experienced the same water-level declines documented in some neighboring counties over the same period -- a genuinely more favorable local trend than the broader regional Ogallala depletion story might suggest on its own.

For a buyer evaluating a specific well or drilling prospect, that split means the aquifer question is not settled by "Randall County = Ogallala decline." Which aquifer a target parcel's water table sits above or below -- and what a driller or hydrogeologist would actually expect to hit at what depth -- is a genuinely parcel-specific question here, worth confirming with a local well driller or HPWD directly rather than assuming either the regional Ogallala narrative or the more favorable recent county-level trend automatically applies to a given tract.
