Monitored well · 861 · Division 1 · Water District 49
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
54 measurements from 1954-08-10 to 2024-02-01. Most recent water-level elevation 4203.92 ft, 224.0 ft below ground.
Over the record the level is no trend at 0.22 ft per decade (p = 0.4828, n = 51). 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.
