Well characteristics

Across the wells Daniel Flynn has drilled, the median depth is 540 ft (middle half 405 ft–660 ft), median tested yield 50 gpm, and median static water level 160 ft below ground surface. These summarize the company's own filed logs, not a marketing claim.

"Records span 1987–2026" refers to the earliest and latest well logs attributed to this company in the MoDNR database — the state digitized older paper logs, so the first date is the oldest record on file, not necessarily the company's founding year.
