Well characteristics
Across the wells Lange Drilling Co. has drilled, the median depth is 200 ft (middle half 120 ft–305 ft), median tested yield 15 gpm, and median static water level 85 ft below ground surface. These summarize the company's own filed logs, not a marketing claim.
"Records span 2002–2026" 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.
