Well characteristics

Across the wells Allen's Drilling & Pump Service has drilled, the median depth is 200 ft (middle half 180 ft–205 ft), median tested yield 5 gpm, and median static water level — below ground surface. These summarize the company's own filed logs, not a marketing claim.

Original drilling logs

"Records span 1973–1986" 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.
