Across the wells Norris & Sons has drilled, the median depth is 110 ft (middle half 50 ft–210 ft), median tested yield 7 gpm, and median static water level 25 ft below ground surface. These summarize the company's own filed logs, not a marketing claim.

"Records span 1902–2009" 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.
