Well characteristics
Across the wells Patten Well Drilling has drilled, the median depth is 115 ft (middle half 70 ft–175 ft), median tested yield 5 gpm, and median static water level 40 ft below ground surface. These summarize the company's own filed logs, not a marketing claim.
"Records span 1966–1989" 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.
