Well characteristics

Across the wells Zavala Drilling, Co. has drilled, the median depth is 255 ft (middle half 134 ft–380 ft), median tested yield 17 gpm, and median static water level 136 ft below ground surface. These summarize the company's own filed logs, not a marketing claim.

"Records span 2007–2026" 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.
