Across the wells Montana Salinity Control Association has drilled, the median depth is 23 ft (middle half 18 ft–32 ft), median tested yield 52 gpm, and median static water level 11 ft below ground surface. These summarize the company's own filed logs, not a marketing claim.
Original drilling logs
Recent well logs filed by Montana Salinity Control Association, straight from the public MBMG record:
"Records span 1954–2026" 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.
