Well characteristics
Across the wells Maggiora Bros Drilling Inc. has drilled, the median depth is 260 ft (middle half 160 ft–405 ft), median tested yield 40 gpm, and median static water level 67 ft below ground surface. These summarize the company's own filed logs, not a marketing claim.
"Records span 1960–2026" 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.
