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

16 measurements from 1986-05-30 to 2001-05-15. Most recent water-level elevation 5080.0 ft, 550.0 ft below ground.

Over the record the level is decreasing at -94.81 ft per decade (p = 0.0191, n = 16). 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, 1986-05-30 to 2001-05-15, 16 measurements. The record is decreasing at -94.81 feet per decade (p equals 0.0191), 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.
