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

26 measurements from 1973-06-23 to 2010-04-21.

Over the record the level is no trend at -0.18 ft per decade (p = 0.2905, n = 25). Mann–Kendall with the Hamed–Rao autocorrelation correction, on water-level elevation; rising elevation means more water.

Chart: water level at this well over time, 1973-06-23 to 2010-04-21, 26 measurements. The record is no trend at -0.18 feet per decade (p equals 0.2905), measured on water-level elevation. Rising elevation means more water. The values are downloadable as CSV from the link above.

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.
