Water-level record
58 measurements from 1962-01-01 to 2026-03-23. Most recent water-level elevation 5878.45 ft, 41.55 ft below ground.
Over the record the level is decreasing at -1.43 ft per decade (p = 0.0448, n = 57). 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.
