Well characteristics

Across the wells Fred Ash & Sons has drilled, the median depth is 320 ft (middle half 240 ft–400 ft), median tested yield 16 gpm, and median static water level 164 ft below ground surface. These summarize the company's own filed logs, not a marketing claim.

"Records span 1931–2028" refers to the earliest and latest well logs attributed to this company in the DWR database — the state digitized older paper logs, so the first date is the oldest record on file, not necessarily the company's founding year.
