Median depth is over the permits that report a total depth (about two in three). A permit’s location is what DWR holds — most are spotted from section lines, so the map places a permit to about a mile. The permit file says nothing about how much water a well pumps; the lesson explains what it does and does not record. Source: DWR’s well-permit REST service.
