Well characteristics
Across the wells Boyles Bros. Drilling Co. has drilled, the median depth is 38 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.
