Well characteristics
Across the wells Deharde Water Well Service has drilled, the median depth is 330 ft (middle half 200 ft–420 ft), median tested yield 50 gpm, and median static water level 77 ft below ground surface. These summarize the company's own filed logs, not a marketing claim.
"Records span 2003–2026" refers to the earliest and latest well logs attributed to this company in the TDLR/TWDB database — the state digitized older paper logs, so the first date is the oldest record on file, not necessarily the company's founding year.
