Unclassified
No aquifer or designated-basin assignment — administrative world unknown, kept out of recharge math.
Water-level record
No water-level measurements are cached for this well. It is in the well inventory — permit, construction and aquifer below — but nobody has logged a level we hold.
Geophysical log
DWR holds a geophysical log for this well, run 2025-04-06 (gamma, resistivity, spontaneous_potential). DWR's log page.
Formation picks (DWR)
| Aquifer | Top ft | Base ft | Net sand ft |
|---|---|---|---|
| UPPER ARAPAHOE | 740 | 955 | |
| LOWER ARAPAHOE | 1070 | 1311 | |
| DENVER | 712 |
Net sand is DWR's own reading of the log (its gLogThickness), not the gross interval.
Net sand per aquifer, from the gamma curve
Computed here from DWR's own digital log (LAS): linear gamma index, clean/shale lines at p10/p90 of the gamma over the interval, sand where Vsh < 0.4, beds under 1.0 ft merged. DWR’s own pick is beside it, never averaged with it.
| Aquifer | Interval ft | Net sand ft | Net / gross | DWR net sand ft | Difference ft |
|---|---|---|---|---|---|
| UPPER ARAPAHOE | 740–955 | 45 | 0.21 | ||
| LOWER ARAPAHOE | 1070–1311 | 80 | 0.33 |
A gamma cutoff is a convention, not a measurement. Against DWR’s own picks on 50 wells this one correlates at r 0.86 with a median error near 30% and no bias (how it was scored).
Curves digitized from the scan
Hydrohistorian traced the scanned log automatically. 9 curves passed the confidence gate; 91 did not and are listed with the reason. Screening data: the scan stays the record.

"Curves like this one" is the benchmark row for this curve's class: curves of the same name traced the same way, scored against DWR's own digital log of the same run. r is correlation (the print's own smoothing allowed for); error is mean absolute error as a share of the track's printed range; "below r 0.8" is the share of passing curves in the class that still disagreed with DWR's log, which this curve's own numbers cannot rule out.
The LAS files and every verdict are in the statewide groundwater release
(/data, table gw_digitized); the MCP server's gw_digitized_curves and
gw_net_sand work from them. How well the tracer does was
measured against DWR's own digital logs.

What this page is not
Monitoring records are irregular: measurements cluster where somebody chose to look, so a trend describes this well's record, not the aquifer as a whole. Levels are DWR's published measurements, unedited. A trend here is not a prediction, and it is not a determination about anyone's water right.
