Well characteristics

Across the wells Silva Bros has drilled, the median depth is 253 ft (middle half 163 ft–351 ft), median tested yield 14 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 1949–1963" 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.
