Stream-connected valley fill; recharges and can be depleted by nearby pumping.
Water-level record
54 measurements from 1972-03-14 to 2026-03-21. Most recent water-level elevation 5907.48 ft, 92.52 ft below ground.
Over the record the level is decreasing at -7.22 ft per decade (p = 0.0, n = 47). 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.
