Well characteristics
Across the wells Mckinley Drilling has drilled, the median depth is 1,310 ft (middle half 720 ft–1,890 ft), median tested yield 500 gpm, and median static water level 265 ft below ground surface. These summarize the company's own filed logs, not a marketing claim.
"Records span 1982–2026" 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.
