Well characteristics
Across the wells Bannon Walt Drilling Co. Inc. has drilled, the median depth is 300 ft (middle half 200 ft–450 ft), median tested yield 10 gpm, and median static water level 54 ft below ground surface. These summarize the company's own filed logs, not a marketing claim.
"Records span 1973–2024" 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.
