100 – 400 ft

Regulator

Oklahoma OWRB

Oklahoma Aquifer Regions

Panhandle (Ogallala/High Plains): 100–300 feet, highly productive for irrigation, $25–$42/ft. Central OK (Canadian River alluvium, Garber-Wellington): 150–350 feet, $28–$48/ft. Southern OK (Arbuckle-Simpson limestone): 200–500 feet, excellent quality, $30–$52/ft. Eastern OK (Ouachita Mountains): 150–400 feet in sandstone, $28–$50/ft.

Oklahoma Water Resources Board

Oklahoma wells are regulated by the Oklahoma Water Resources Board (OWRB). Licensed driller required. Well completion report required. Oklahoma has comprehensive groundwater ownership laws — water beneath your land is considered your property (rule of capture).

Common Questions

Oklahoma residential wells typically cost $6,000–$14,000 installed. Central and eastern Oklahoma have moderate costs. The Panhandle and southern limestone regions vary by depth.

Oklahoma uses the rule of capture for groundwater — landowners can pump water beneath their land. However, some aquifers are being depleted (particularly the Ogallala in the Panhandle). OWRB manages basin-specific rules for some aquifers.
