Comal County Has Strong Household Evidence and Loud Shallow Noise

Comal County contains 4,992 submitted driller records. Most belong to the domestic lane: 3,680 rows were filed for household use, and 3,679 of them report a positive total depth. That is a substantial local sample for rural buyers around New Braunfels, Spring Branch, Bulverde, Canyon Lake, Fischer, and Garden Ridge.

The same county file also holds 665 environmental soil borings averaging only 15.9 feet and 258 monitor records averaging 56.9 feet. Those shallow records can overwhelm a broad search even though they were not drilled to supply a Hill Country home. A county average that blends them with domestic, public-supply, industrial, and irrigation work answers no useful household question.

Start with the Texas water well records lookup when screening property. When one tract becomes a serious purchase, construction, or replacement candidate, use a Pre-Drill Intelligence Report to narrow the comparison set to nearby records with relevant coordinates, uses, and source documents. TurnKey Wells organizes public evidence; it does not drill wells or guarantee field results.

What 3,679 Domestic Depth Logs Show

The usable domestic subset has a median total depth of 490 feet. The middle half of the filings runs from 400 to 600 feet, and 90 percent are at or below 680 feet. The reported range is 10 to 1,420 feet, with an average of 504.8 feet.

That distribution is a research baseline, not a drilling forecast. Only 31 domestic rows fall below 100 feet, while 3,373 fall between 300 and 700 feet. Another 349 are 700 feet or deeper, including 54 above 1,000 feet. A short or very deep record deserves source review; it should not become a best-case bid, a worst-case ceiling, or an automatic comparison for a tract elsewhere in the county.

One domestic row does not carry a positive total-depth value. It remains part of the domestic count but not the depth calculation. Missing values should not silently become zeros, and a clean-looking statistic should never outrank coordinates, use class, record age, construction details, and the original filing.

• Total Comal County SDR rows: 4,992
• Total domestic rows: 3,680
• Usable domestic total-depth logs: 3,679
• Median domestic total depth: 490 ft
• Domestic total-depth middle band: 400 to 600 ft
• Domestic 90th-percentile marker: 680 ft
• Recorded domestic total-depth range: 10 to 1,420 ft
• Average domestic total depth: 504.8 ft

Pump-Depth Records Describe Older Equipment Decisions

There are 1,998 domestic filings with a positive pump depth. Their median is 460 feet, and the middle half runs from 380 to 540 feet. Ninety percent are at or below 600 feet, while the reported settings range from 26 to 905 feet. The sample average is 454.1 feet.

Those numbers describe historical filings, not where a pump belongs in a new or existing well. Total depth tells how far a completed hole extends. Pump setting is an equipment decision informed by static water level, anticipated drawdown, household or livestock demand, pump characteristics, and the contractor’s evaluation of the completed well.

Ask a contractor to separate drilling footage from pump, pressure, electrical, storage, and treatment allowances. If a nearby report includes a pump setting, confirm that it belongs to the same well and makes sense beside its construction details before treating it as a comparison.

Soil Borings and Public-Supply Wells Pull in Opposite Directions

The county’s 665 environmental soil borings average 15.9 feet and range from 1 to 150 feet. The 258 monitor records average 56.9 feet, although their broad range includes entries that require source review. These lanes can be useful for site-history or environmental questions, but they do not belong in a household depth estimate.

The deeper and larger-demand side can distort planning in the other direction. Comal County has 105 public-supply rows, 104 with positive depths averaging 723.5 feet. Its 56 industrial records average 718.9 feet, while 39 test wells average 607.8 feet. Irrigation has 93 positive-depth records averaging 470.3 feet, and stock has 38 averaging 529.6 feet.

These are legitimate records with different jobs. A public system, industrial completion, test hole, irrigation project, and household well can share a county name without sharing demand, design, completion, or regulatory path. Use class must travel with every depth number.

Place Names Are Helpful Until They Become a Shortcut

New Braunfels, Spring Branch, Bulverde, and Canyon Lake appear frequently in the county file. Fischer and Garden Ridge also appear, along with capitalization variants, spelling variants, blanks, and labels such as San Antonio, Blanco, Boerne, and Schertz. A mailing city can describe an address or route rather than the well’s exact physical location.

Coordinates and proposed use should control tract-level comparisons. Two records labeled New Braunfels can lie on different sides of a groundwater or regulatory boundary, and one might serve a home while another belongs to a commercial or public system. A city filter is a convenient first pass, not proof that two completions share geology, groundwater conditions, or jurisdiction.

Hill Country topography makes that discipline even more important. A ridge, valley, faulted interval, access constraint, or nearby development pattern can change the useful comparison set within a short drive. Open the source records instead of treating a familiar place name as the final answer.

Trinity and Edwards Labels Need Tract-Level Context

The groundwater database contains 734 Comal County rows. Trinity is the largest named group at 406 records. Edwards (Balcones Fault Zone) appears on 264 rows, followed by 52 unassigned and 12 Other records.

The Texas Trinity aquifer guide and Edwards Balcones Fault Zone aquifer guide provide regional context for those labels. They do not prove which aquifer serves a tract, and they do not promise depth, yield, standing water level, or chemistry. A county can hold strong evidence from both systems while a specific property depends on one local interval and one regulatory lane.

Unassigned and Other labels are reasons to keep the investigation local. Plot the nearest relevant wells, open the source documents, note record age and use, and ask a licensed driller how that history relates to the proposed site and current demand.

Two Groundwater Authorities Can Enter the Comal County Conversation

Comal Trinity Groundwater Conservation District and the Edwards Aquifer Authority are both relevant to Comal County groundwater questions, but they are not interchangeable and their geography and authority differ. A county name alone cannot establish which rules apply to a well or tract.

Enter the property’s street address or coordinates in the Texas groundwater conservation district lookup. If Edwards recharge, contributing, or artesian-zone mapping may be relevant, review the Edwards Aquifer Authority’s current mapping and requirements as well. Then confirm registration, permitting, spacing, production, replacement-well, and plugging questions directly with the authority responsible for that exact property and proposed use.

The database also contains 788 plugged-well rows assigned to Comal County. That count establishes county history only. It does not prove a plugged, abandoned, or undocumented well exists on a property. For land sold with an existing private well, the Texas water-well disclosure guide can help organize seller records, equipment details, service history, tests, and unanswered questions.

Depth Does Not Answer the Water-Quality or Yield Question

A 490-foot median does not tell a buyer what will come from a faucet. Water chemistry can vary with the producing interval, well condition, construction, nearby activity, treatment equipment, and household plumbing. Karst and fractured-rock settings also make source protection, surface activity, and completion details worth discussing directly with qualified professionals.

An operating well needs a current sample collected appropriately and analyzed by a qualified laboratory for the property and intended use. Ask when the system was last serviced, how a sample was collected, and whether treatment equipment was bypassed. An older result can be valuable history without being a current answer.

Quantity is separate from quality. Neither a filed depth, pump setting, aquifer label, nor nearby public-supply completion guarantees household yield. Public evidence can sharpen the questions, but field measurements and licensed contractor guidance must establish present performance.

Price the Complete Hill Country System

The domestic depth figures are planning references, not contractor prices. A full Comal County budget may include mobilization, drilling, casing, completion materials, pump and controls, pressure equipment, trenching, electrical work, storage, testing, treatment, freeze protection, and cleanup. Rocky access, slope, gate width, overhead lines, septic placement, neighboring improvements, and distance to power can affect the plan before drilling begins.

The Texas water well drilling cost guide explains the categories behind a headline estimate. Ask each licensed contractor what is included, what remains an allowance, how added footage is priced, who coordinates power and testing, and what happens if the completed well calls for different equipment than the first proposal assumed.

Existing wells require the same discipline. Low pressure or poor performance might involve the pump, pressure tank, controls, power supply, water level, well condition, treatment equipment, or more than one issue. Records can establish history; diagnosis and repair pricing belong to qualified professionals working from the current system.

Nearby County Pages for Comparison

Bexar and Blanco border Comal County. Caldwell provides another published comparison across the nearby I-35 and rural-growth corridor while Hays, Guadalupe, and Kendall pages await their own reviewed coverage. These three pages show how quickly domestic depths, aquifer labels, use mixes, and regulatory questions change:

• Water well drilling records in neighboring Bexar County

Turn the Comal County File Into a Property Decision

This page is for buyers, landowners, agents, and rural sellers working around New Braunfels, Spring Branch, Bulverde, Canyon Lake, Fischer, Garden Ridge, and the acreage between them. Comal County offers a large household record file, but that volume becomes useful only after shallow borings, monitor points, larger-demand projects, aquifer clues, and jurisdiction questions are kept in their proper lanes.

If you are screening several properties, begin with the Free Well Check. If one tract has reached the inspection, negotiation, financing, or building stage, use the Pre-Drill Intelligence Report to assemble nearby evidence and unresolved questions in one place.
