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
25 measurements from 2001-05-07 to 2026-02-25. Most recent water-level elevation 4071.04 ft, 138.01 ft below ground.
Over the record the level is decreasing at -6.77 ft per decade (p = 0.0, n = 24). 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, 2001-05-07 to 2026-02-25, 25 measurements. The record is decreasing at -6.77 feet per decade (p equals 0.0), 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.
