Well characteristics
Across the wells Castle Construction & Well Drilling Inc. has drilled, the median depth is 298 ft (middle half 220 ft–313 ft), median tested yield 35 gpm, and median static water level 70 ft below ground surface. These summarize the company's own filed logs, not a marketing claim.
"Records span 1966–2019" 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.
