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
57 measurements from 1969-03-11 to 2026-02-10. Most recent water-level elevation 3889.34 ft, 130.4 ft below ground.
Over the record the level is decreasing at -12.05 ft per decade (p = 0.0, n = 57). 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, 1969-03-11 to 2026-02-10, 57 measurements. The record is decreasing at -12.05 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.
