Well characteristics

Across the wells Layne-Western Co. Inc. has drilled, the median depth is 453 ft (middle half 226 ft–800 ft), median tested yield 1,500 gpm, and median static water level 93 ft below ground surface. These summarize the company's own filed logs, not a marketing claim.

"Records span 1976–1991" 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.
