Well characteristics
Across the wells Weeks Drilling And Pump Co. has drilled, the median depth is 165 ft (middle half 88 ft–260 ft), median tested yield 20 gpm, and median static water level 33 ft below ground surface. These summarize the company's own filed logs, not a marketing claim.
"Records span 1941–2026" 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.
