Well Water and the New Briggs-Oakalla Rules in Burnet County, Texas

Why CTGCD created a new zone in northeast Burnet County

The Central Texas Groundwater Conservation District (CTGCD) regulates groundwater across Burnet County under authority the Texas Legislature granted in 2005. Starting in early 2025, the district began a formal, publicly noticed process focused specifically on the Briggs-Oakalla area of northeast Burnet County, holding public meetings in March and April 2025 to explain the science behind a proposed new management zone before moving to a rule-making hearing. CTGCD's stated reasons for singling out this particular area were concrete, not speculative: declining water levels in the Trinity Aquifer there, measurable water-quality degradation, an unusually high density of existing wells relative to the surrounding area, and a pipeline of approved subdivisions that would add still more wells drawing from the same limited aquifer segment.

That process concluded with a well-attended rule-making hearing on January 23, 2026, at which the district received public feedback, made adjustments, and formally adopted new rules creating the Northeast Burnet County Trinity Aquifer Management Zone (NBCTAMZ), effective that same day. This kind of area-specific sub-zone, layered on top of a district's general countywide rules, is exactly the sort of local wrinkle the state hub flags as something that can vary within a single GCD's territory -- CTGCD's general rules still apply to the rest of Burnet County, while the NBCTAMZ's stricter rules apply only inside its defined boundary.

The core change: minimum tract size for a well jumped from 2 to 10 acres

The single biggest practical change in the new rules is the minimum tract size required to support a permitted well inside the NBCTAMZ boundary: it rose from 2 acres to 10 acres. Contemporaneous local reporting summarized the practical effect plainly -- where roughly five wells might previously have been permitted across a given area under the old 2-acre standard, only one well is now permitted across that same land area under the new 10-acre standard. That is a five-fold reduction in well density, driven directly by CTGCD's stated concern about the aquifer's ability to support continued subdivision-driven growth in this specific pocket of the county.

This matters most for anyone evaluating a smaller acreage tract in the Briggs-Oakalla area specifically for its own well: a 2-to-5-acre parcel that might have qualified for a well under the district's general rules before January 2026 may no longer qualify inside the new zone, which directly affects both the land's usability without a well and its subdivision potential going forward. A related 2023 dispute over a proposed subdivision near Briggs -- reported locally as failing to get a vote from Commissioners Court over water-supply concerns, with local reporting suggesting the denial could bring legal exposure -- reflects the same underlying tension CTGCD's 2026 rule-making was created to address: subdivision growth outpacing what the local aquifer segment can support.

What to verify before buying in northeast Burnet County

1. Ask CTGCD directly whether a specific parcel falls inside the Northeast Burnet County Trinity Aquifer Management Zone boundary -- the zone covers the Briggs-Oakalla area specifically, not the whole county, so a nearby parcel just outside the boundary may still fall under the district's general 2-acre-or-different standard.
2. If the parcel is inside the zone and under 10 acres, confirm directly with CTGCD whether it can still qualify for a permitted well under any exemption or prior-permit provision, rather than assuming the new 10-acre minimum is an absolute bar.
3. For a parcel that's part of a larger tract being subdivided, ask CTGCD and the county whether the new rules affect how many lots the tract can be divided into if each lot is meant to rely on its own well.
4. Ask about the current water level and any monitoring data for the specific area, since CTGCD's own stated rationale was a documented decline -- a seller's claim about "plenty of water" is worth checking against the district's own data before relying on it.
