Other bedrock
Bedrock aquifer; no assumed human-timescale recharge without local evidence.
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
37 measurements from 1965-04-23 to 2026-02-26. Most recent water-level elevation 3831.72 ft, 318.28 ft below ground.
Over the record the level is decreasing at -31.65 ft per decade (p = 0.0, n = 35). 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, 1965-04-23 to 2026-02-26, 37 measurements. The record is decreasing at -31.65 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.
