| No fixed day-of-week schedule – no active restrictions | Verify at stillwaterok.gov before any change |
Allowed Watering Hours
Stillwater Utilities Authority does not currently have any restrictions on water usage. Best-practice voluntary guidance for Oklahoma summers is to avoid sprinkler irrigation between 10:00 AM and 6:00 PM (evaporation losses), but this is recommendation, not requirement. Mandatory restrictions would activate only if SUA declares a specific stage – verify current status at stillwaterok.gov before assuming a change.
Still Allowed
💧 Hand Watering
Allowed with shut-off nozzle. Hours: Any day with a shut-off nozzle (no restrictions currently in effect).
🌿 Drip Irrigation
Exempt from day-of-week limits. Must follow allowed hours.
Fines & Enforcement
No fines – no active restrictions
There are no fines because there are no active mandatory restrictions. SUA's water-conservation framework would activate only if the Stillwater Utilities Authority Board declares a specific stage under the trust indenture.
🏠 HOA Rules During Restrictions
Even without active municipal restrictions, the Oklahoma Residential Property Act framework still applies: HOA rules cannot mandate irrigation practices that conflict with future municipal ordinances. During Stillwater's current no-restrictions period, HOA appearance rules govern; document any future SUA stage declaration if your HOA later challenges a brown lawn.
If your homeowners association sends a violation notice for a dormant or brown lawn during the current restriction period, respond in writing citing the applicable law and include a copy of the current restriction order from Stillwater Utilities Authority. Most HOAs will rescind the notice once they are made aware of the legal protections in place. If the issue persists, contact your county’s code enforcement division for assistance.
Why These Restrictions Exist
Stillwater is served by the Stillwater Utilities Authority (SUA) – one of Oklahoma's more comprehensive combined municipal utility systems, providing water, electric, wastewater collection, and trash and recycling collection under a single trust authority. SUA was established by city ordinance in 1979 under a Trust Indenture amended in 1980 and again in 2014. The mayor and city council serve as trustees and govern the authority on behalf of Stillwater residents, businesses, and institutions.
Source water: SUA's primary water supply is the Kaw River, accessed via the city's Kaw pump station and a raw-water pipeline that delivers Kaw River water to the Stillwater Water Treatment Plant for processing. SUA also coordinates with Lake Carl Blackwell (an OSU-owned reservoir adjacent to the city) on supplemental and historical supply arrangements, and operates booster pump stations plus treated water storage tanks across the distribution system.
Current status: As of the most recent SUA publication, the City of Stillwater does not have any restrictions on water usage. Best-practice voluntary guidance (avoid mid-day sprinkler irrigation, fix leaks promptly, harvest rainwater) is published by the city as conservation outreach but is not mandatory. Stage-based restrictions would activate only if SUA declares a specific stage.
Recent infrastructure: SUA received approximately $39 million in 2023 funding from the Oklahoma Water Resources Board (OWRB) to improve the authority's water infrastructure – treatment plant capacity, pipeline modernization, and storage improvements.
Statewide context: Oklahoma is in active drought. Payne County tracks D1 Moderate per the US Drought Monitor as of the most recent reporting. The February 2026 Ranger Road Fire (283,283 acres) drove regional burn bans across central and eastern Oklahoma. Although Stillwater itself does not have active water-use restrictions, the statewide drought context underpins SUA's coordination with OWRB on water-system resilience planning.
Local context: Oklahoma State University (OSU – roughly 25,000 students) is the local economic and cultural anchor and a major institutional water consumer on a separate university account with SUA. OSU agricultural research stations (the Wes Watkins Agricultural Research and Extension Center, the OSU Agronomy Research Station) are additional institutional water users.
This deficit has accumulated over the current water year and represents a significant departure from historical averages for the Stillwater area. Water supply reservoirs and aquifer levels are below seasonal targets, prompting regional voluntary conservation guidance.
How to Keep Your Lawn Alive During Stillwater Water Restrictions
11 tips tailored for Stillwater homeowners during No active water-use restrictions – verify at stillwaterok.gov restrictions.
Stillwater currently has NO active water-use restrictions per the most recent SUA publication – verify at stillwaterok.gov before assuming any rules apply.
Best-practice voluntary guidance: water before 10 AM or after 6 PM to minimize evaporation losses. This is recommendation, not requirement.
Bermuda and zoysia dominate Stillwater lawns and handle Oklahoma summers well without mandatory schedules; tall fescue is common in older neighborhoods near OSU but browns severely under summer heat.
Cycle-and-soak on Stillwater's red clay soils: 8 minutes on, 30-minute pause, 8 minutes on – useful even outside mandatory restrictions because runoff is wasted irrigation.
Mulch ornamental beds 3 inches deep with arborist wood chips; bare soil in central Oklahoma summer loses 0.5+ inches of moisture per day.
Drip-irrigate trees, shrubs, and vegetable beds – more efficient than overhead spray under any framework.
Audit sprinkler heads monthly for overspray onto sidewalks and driveways; even without mandatory restrictions, visible waste affects long-term aquifer drawdown.
Skip cycles after 0.25 inch or greater rainfall in the prior 48 hours; Oklahoma rain sensors are required on systems installed after 2010 under city code.
Convert parkway strips to Oklahoma natives (Buffalo Grass, Side-Oats Grama, Little Bluestem) – these are well-adapted to OSU's research-station climate and aligned with SUA's voluntary conservation guidance.
Track monthly use at stillwaterok.gov utility portal – SUA's combined-services bill shows water alongside electric, wastewater, and trash on a single statement.
Harvest rainwater off downspouts into rain barrels – Oklahoma law permits residential capture without restriction.
