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
22 measurements from 1954-07-06 to 1972-01-24. Most recent water-level elevation 3809.76 ft, 157.65 ft below ground.
Over the record the level is decreasing at -2.54 ft per decade (p = 0.0003, n = 22). 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, 1954-07-06 to 1972-01-24, 22 measurements. The record is decreasing at -2.54 feet per decade (p equals 0.0003), 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.
