Across the wells Boyles Bros. Drilling Co. has drilled, the median depth is 39 ft (middle half 26 ft–58 ft), median tested yield 10 gpm, and median static water level — below ground surface. These summarize the company's own filed logs, not a marketing claim.

Original drilling logs

Recent well logs filed by Boyles Bros. Drilling Co., straight from the public DWR record:

"Records span 1908–1996" 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.
