108 more wells with one reading or none
DWR lists these but the cache holds at most a single measurement for each, so their pages show a location and an aquifer, not a record.

The aquifer is the one DWR assigns the well; depth is the well’s reported total depth. Readings are what the site’s cache holds. Source: DWR HydroBase, groundwater water-level wells and measurements.
