Well characteristics

Across the wells Cascade Drilling LP has drilled, the median depth is 40 ft (middle half 16 ft–56 ft), median tested yield 30 gpm, and median static water level 11 ft below ground surface. These summarize the company's own filed logs, not a marketing claim.

"Records span 2002–2026" 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.
