Hydrohistorian
High Plains / Ogallala
Effectively non-recharging in eastern Colorado; declines are storage depletion, a separate ledger line.
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
11 measurements from 1975-07-01 to 1987-11-13. Most recent water-level elevation 4736.05 ft, 98.68 ft below ground.
Over the record the level is no trend at -12.49 ft per decade (p = 0.7555, n = 11). 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, 1975-07-01 to 1987-11-13, 11 measurements. The record is no trend at -12.49 feet per decade (p equals 0.7555), 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.
