Well characteristics
Across the wells Walt Bannon Drilling Inc. has drilled, the median depth is 425 ft (middle half 250 ft–605 ft), median tested yield 9 gpm, and median static water level 133 ft below ground surface. These summarize the company's own filed logs, not a marketing claim.
"Records span 1953–2026" 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.
