# Monitoring/sampling well permits in Boulder County, Colorado — 3,864

> The 3,864 wells permitted for monitoring/sampling in Boulder County. Median depth 19 feet.

## Monitoring/sampling wells in Boulder County

**3,864** of the 20,791 well permits in Boulder County — 18.6% — are decreed for monitoring/sampling.

### How this group compares

Boulder County holds 4.2% of
Colorado’s 91,022 monitoring/sampling permits, while
holding 3.5% of the register overall — so it is
**over-represented** in this
use.

Monitoring/sampling means not a water supply at all — a hole drilled to watch the groundwater. These sit on the same register and are not wells anyone drinks from.

*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 | **19 ft** | 50 ft | 148 ft — shallower here (2,425 permits, 63 %) |
| Yield | **15 gpm** | 30 gpm | 10 gpm — higher here (4 permits, 0 %) |
| Static water level | **9 ft** | 26 ft | 58 ft — lower here (542 permits, 14 %) |

### What happened to these permits

**2,021** of the 3,864 permits decreed for monitoring/sampling in Boulder County ended with a
well the Division was told about — 52.3%. And
**900** expired without one: 23.3%.

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.
