Denver Basin bedrock
Confined sandstone aquifer; negligible human-timescale recharge — pumping is one-way storage mining.
Because this aquifer does not recharge on a human timescale, a decline here is storage being removed, not a stream being short. It is kept out of the stream-depletion math for that reason.
Water-level record
33 measurements from 1988-03-29 to 2024-02-14. Most recent water-level elevation 6372.36 ft, 186.64 ft below ground.
Over the record the level is no trend at 18.64 ft per decade (p = 0.5338, n = 33). Mann–Kendall with the Hamed–Rao autocorrelation correction, on water-level elevation; rising elevation means more water.

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.
