Well characteristics
Across the wells Rottman Drilling Co. has drilled, the median depth is 482 ft (middle half 290 ft–690 ft), median tested yield 544 gpm, and median static water level 206 ft below ground surface. These summarize the company's own filed logs, not a marketing claim.
"Records span 1944–2018" 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.
