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
14 measurements from 2013-03-06 to 2026-01-19. Most recent water-level elevation 3793.0 ft, 247.0 ft below ground.
Over the record the level is no trend at -2.44 ft per decade (p = 0.2496, n = 14). Mann–Kendall with the Hamed–Rao autocorrelation correction, on water-level elevation; rising elevation means more water.

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.
