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
30 measurements from 1962-03-30 to 1988-04-06. Most recent water-level elevation 4929.46 ft, 27.2 ft below ground.
Over the record the level is decreasing at -1.21 ft per decade (p = 0.0009, n = 30). 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, 1962-03-30 to 1988-04-06, 30 measurements. The record is decreasing at -1.21 feet per decade (p equals 0.0009), 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.
