## The Lower Dawson aquifer

### What this aquifer is

an aquifer the Division records under this name.

Which aquifer a well draws on is not administrative detail: the
Denver Basin formations have their own legal regime, and alluvial water is
tied to the surface stream, which is why it is regulated differently. The
depth below is the practical consequence.

*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 | **480 ft** | 753 ft | 148 ft — deeper here (3,336 permits, 67 %) |
| Yield | **12 gpm** | 15 gpm | 10 gpm — higher here (2,689 permits, 54 %) |
| Static water level | **240 ft** | 470 ft | 58 ft — higher here (3,391 permits, 69 %) |

### What happened to these permits

**3,122** of the 4,944 permits on this aquifer ended with a
well the Division was told about — 63.1%. And
**537** expired without one: 10.9%.

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.
