Well characteristics
Across the wells Schlesser & Sons has drilled, the median depth is 41 ft (middle half 34 ft–54 ft), median tested yield 7 gpm, and median static water level — below ground surface. These summarize the company's own filed logs, not a marketing claim.
Original drilling logs
Recent well logs filed by Schlesser & Sons, straight from the public ISGS record:
"Records span 1948–1949" refers to the earliest and latest well logs attributed to this company in the ISGS database — the state digitized older paper logs, so the first date is the oldest record on file, not necessarily the company's founding year.
