Duncan will move to a higher water conservation status that will take effect later this fall.
The Duncan Banner reports the Stage 4 rationing won't be enforced until October to give residents time to adjust their water usage.
The city revised that status, which previously prohibited all outdoor water usage, to allow residents to use water outside one day each week.
Residents living north of Elk Avenue will be allowed to water their lawns for nine hours on Wednesday. Those living south of Elk Avenue can do so on Saturdays.
The city's water supply is diminishing. Its main water source is Waurika Lake, which public works director Scott Vaughn says is "still plummeting."
