# Water wells in Johnson County, Kansas — 5,602 WWC-5 records

> 5,602 water well records in Johnson County. The median well is 18 feet deep. Who drilled them, how deep, and which ones have no plugging report on file.

## Water wells in Johnson County

**5,602** WWC-5 records — 1.8% of the Kansas register. The median well here is **18 feet** deep, against 60 feet statewide.

### How deep people drill in Johnson County

This is what a buyer or a builder actually wants, and the Survey does not publish it as a figure you can look up. The numbers below are medians over the records where a figure was reported — a mean would be carried away by a few deep irrigation wells.

*Medians, on the records where the driller reported a figure — never a mean, which a handful of deep irrigation wells would carry away*

| Measurement | Median | 90th percentile | Kansas median |
|---|---|---|---|
| Depth | **18 ft** | 183 ft | 60 ft — shallower here (5,565 records, 99 %) |
| Static water level | **8.84 ft** | 28.8 ft | 24 ft — lower here (3,314 records, 59 %) |
| Estimated yield | **3 gpm** | 100 gpm | 25 gpm — lower here (316 records, 6 %) |

### Wells tied to a water right

**43** records in Johnson County carry a DWR
appropriation number — 0.8%, against 11.0% statewide. A
well permit and a water right are separate instruments in Kansas, and the
appropriation number is the thread back to the Division of Water
Resources.

### What stands out in Johnson County

The busiest contractor on these records is **Evans Energy Development, INC**, named on 398 of them (7.1%), ahead of Larsen and Associates, INC (316) and Below Ground Surface, INC (270). The oldest record here was completed in **1971** and the most recent in 2026, and the deepest well on file reaches **700 feet** — a domestic well drilled by Cullum and Brown in 1974.

### Plugging records — in Johnson County

**1,786** of the 5,602 records in Johnson County carry a
plugging report (31.9%), filed on form WWC-5P. The other
**3,816** do not.

That is **not** a list of abandoned wells, and
this site never calls them that. Kansas defines abandonment by
*use* — a well unused for two years — and nothing in this
register tracks use. What the absence of a plugging report does mean is that
the State has never been told the well was sealed. On the
**708** records here completed before 1995, that is
exactly what a buyer checks. [Why it matters and who
pays](/abandoned.md).

### An unplugged well on land in Johnson County?

3,816 of the 5,602 records in Johnson County have no plugging report on file. If a well on your land is no longer used, Kansas requires it to be plugged and the duty falls on the landowner — with cost-share of up to USD 1,000 per well through the Kansas Department of Agriculture. This site reads the register; it does not drill and it does not plug. Tell us where and we pass the request to licensed Kansas well contractors.

We recommend no contractor and we are nobody's agent. We have no arrangement with any firm today — we are collecting these requests in order to go and find them. [What we do with this](/privacy.md).

### Records in Johnson County

*Johnson County — « plugging report » reads *yes* where a WWC-5P was filed and a dash where none was, which is NOT a finding that the well is abandoned. A 0 means the driller reported no figure, not a measurement of zero. The legal description is on the record, never on a page.*
