Well characteristics
Across the wells W D C Exploration & Wells has drilled, the median depth is 68 ft (middle half 27 ft–235 ft), median tested yield 90 gpm, and median static water level 26 ft below ground surface. These summarize the company's own filed logs, not a marketing claim.
"Records span 1940–2012" 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.
