Well characteristics

Across the wells Corveau Drilling has drilled, the median depth is 150 ft (middle half 78 ft–275 ft), median tested yield 20 gpm, and median static water level 47 ft below ground surface. These summarize the company's own filed logs, not a marketing claim.

Original drilling logs

Recent well logs filed by Corveau Drilling, straight from the public MBMG record:

"Records span 1978–2022" refers to the earliest and latest well logs attributed to this company in the MBMG database — the state digitized older paper logs, so the first date is the oldest record on file, not necessarily the company's founding year.
