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
27 measurements from 1991-11-08 to 2026-09-10. Most recent water-level elevation 6768.09 ft, 102.01 ft below ground.
Over the record the level is decreasing at -10.9 ft per decade (p = 0.0005, n = 21). 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, 1991-11-08 to 2026-09-10, 27 measurements. The record is decreasing at -10.9 feet per decade (p equals 0.0005), 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.
