How deep people drill in Larimer 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 | 180 ft | 600 ft | 148 ft — deeper here (14,026 permits, 67 %) |
| Yield | 6 gpm | 15 gpm | 10 gpm — lower here (5,438 permits, 26 %) |
| Static water level | 30 ft | 135 ft | 58 ft — lower here (11,107 permits, 53 %) |
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
12,269 of the 20,919 permits in Larimer County ended with a well the Division was told about — 58.7%. And 3,168 expired without one: 15.1%.
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.
