Water rights & wells in Johnston County

Whether a new home can legally get its own water here — the sub-state groundwater regime, from Oklahoma’s water agency.

Actively managed

This basin is under active state management — new water use is scrutinized, though a domestic well is usually still allowed.

Household wellExempt — no permit or water right

Oklahoma groundwater is tied to the overlying land rather than allocated by prior appropriation, and 'domestic use' — household use, farm/domestic animals, and irrigation of up to 3 acres of gardens/orchards/lawns — needs no permit at all.

Limit: Domestic use exempt from any permit; non-domestic groundwater allocated by overlying land ownership (default 2 acre-ft/acre/yr)

Oklahoma Water Resources Board — Groundwater Permitting
  • Arbuckle-Simpson Sensitive Sole Source Groundwater Basinpartial of county

    Oklahoma's only designated 'sensitive sole source' groundwater basin; permitted allocation capped far below the statewide default (0.20 acre-ft/acre/yr) to protect spring/stream flow, with a moratorium on out-of-basin municipal permits; domestic use remains exempt.
