Well characteristics
Across the wells Big Valley Drilling has drilled, the median depth is 338 ft (middle half 180 ft–522 ft), median tested yield 470 gpm, and median static water level 50 ft below ground surface. These summarize the company's own filed logs, not a marketing claim.
"Records span 1972–2019" 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.
