How deep people drill in Jefferson County
This is the part a buyer actually wants, and it is not published anywhere else. The figures below are medians over the permits where the Division was told — a mean would be carried away by a handful of industrial wells.
| Measurement | Median | 90th percentile | Colorado median |
|---|---|---|---|
| Depth | 203 ft | 645 ft | 148 ft — deeper here (27,288 permits, 64 %) |
| Yield | 6 gpm | 13.1 gpm | 10 gpm — lower here (9,200 permits, 22 %) |
| Static water level | 60 ft | 210 ft | 58 ft — higher here (19,433 permits, 45 %) |
What the permits allow
A well permit is not a general right to water: it names what the water may be used for, and the narrowest of them — household use only — means inside the house and nothing else.

What happened to these permits
24,543 of the 42,751 permits in Jefferson County ended with a well the Division was told about — 57.4%. And 7,091 expired without one: 16.6%.
An expired permit is the trap in a rural sale. A seller can produce a permit that lapsed years ago, and a permit is not a water right — the two are separate, and a purchase turns on both. What an expired permit does and does not mean.
