Every figure here comes from a report a licensed driller filed on the day the work ended — sometimes decades ago. It describes what was found then, not what a well yields today, and it is not a statement that any well is sound, potable or still in use.

This page counts reports, not quality, and it is not a recommendation. A firm that files more reports drills more wells — nothing else follows.
