## Well permits in Boulder County

**20,791** well permits — 3.5% of Colorado’s register. The median well here is **145 feet** deep, against 148 feet statewide.

### How deep people drill in Boulder 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.

*Medians, on the permits where the Division was told — never a mean, which a few industrial wells would carry away*

| Measurement | Median | 90th percentile | Colorado median |
|---|---|---|---|
| Depth | **145 ft** | 500 ft | 148 ft — shallower here (13,854 permits, 67 %) |
| Yield | **7 gpm** | 15 gpm | 10 gpm — lower here (3,958 permits, 19 %) |
| Static water level | **30 ft** | 150 ft | 58 ft — lower here (9,604 permits, 46 %) |

### 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.

| Decreed use | Permits | Share |
|---|---|---|
| [Domestic](/county/boulder/domestic.md) | 8,225 | 39.6% |

### What happened to these permits

**12,169** of the 20,791 permits in Boulder County ended with a
well the Division was told about — 58.5%. And
**3,073** expired without one: 14.8%.

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.
