Little Rock AR Water Restrictions 2026

Current water restrictions in Little Rock, Arkansas

Little Rock currently has no active mandatory water restrictions in place, but Central Arkansas Water (also operating as Little Rock Water Works) has issued a voluntary Stage 1 Advisory recommending residents limit outdoor irrigation to three days per week using an odd/even address schedule.

Central Arkansas Water coordinates water management for the Little Rock metro area and monitors drought conditions in partnership with the Arkansas Natural Resources Commission and the U.S. Drought Monitor. As of April 2026, the region is being watched for drought development, even though statewide conditions are classified as normal with no active restrictions at the Arkansas state level.

The voluntary guidance is not a declared emergency order — it is a proactive conservation advisory issued by Central Arkansas Water to protect long-term system capacity and reduce demand on the Maumee Lake and Lake Winona supply system during periods of reduced rainfall. Central Arkansas Water has not published a specific rainfall deficit figure publicly; contact them directly at carkw.com or 501-377-1242 for current data.

Practically speaking: yes, a Little Rock resident can water their garden on a Wednesday morning — as long as they finish before 10:00 AM. Under the voluntary Stage 1 Advisory, odd-numbered addresses are encouraged to water Monday, Wednesday, and Friday; even-numbered addresses on Tuesday, Thursday, and Saturday. Midday watering between 10:00 AM and 5:00 PM is discouraged to reduce evaporation loss. Because this is a voluntary advisory, there are no fines for non-compliance at this stage — but compliance helps prevent Central Arkansas Water from declaring a mandatory Stage 2 restriction with real enforcement.

Your assigned watering schedule

Address parity in Little Rock is determined by the last digit of your street address number. If your address ends in 1, 3, 5, 7, or 9, you are an odd address and should follow the Monday/Wednesday/Friday schedule. Even addresses — ending in 0, 2, 4, 6, or 8 — follow Tuesday/Thursday/Saturday. Sunday is a rest day under the advisory for all addresses.

Multi-family properties and commercial accounts should use the address of the primary meter connection to determine their assigned days. Businesses with large commercial irrigation systems — including apartment complexes and retail centers along Chenal Parkway or Colonel Glenn Road — are encouraged to contact Central Arkansas Water directly to discuss account-level scheduling, particularly if a single property spans multiple meter connections with different address parities.

If you have recently installed new sod or seeded bare areas, Central Arkansas Water provides a 21-day establishment variance that allows more frequent watering to get turf rooted before the advisory schedule kicks in. You must register for this variance; do not assume it applies automatically. Little Rock landscapes commonly feature Southern Red Oak (Quercus falcata), Eastern Redbud (Cercis canadensis), and Bald Cypress (Taxodium distichum) — all of which benefit from deep, infrequent watering at the drip line during dry periods rather than frequent shallow sprinkler coverage.

Fines and penalties

Because Little Rock is currently under a voluntary Stage 1 Advisory, Central Arkansas Water does not issue fines for failing to follow the odd/even schedule. Enforcement authority activates only if Central Arkansas Water formally declares a Stage 2 mandatory restriction. At that point, water use officers and customer service representatives begin monitoring complaints submitted through the Central Arkansas Water website at carkw.com and by phone at 501-377-1242. The utility has deployed automated meter infrastructure (AMI) smart meters across much of the Little Rock service area, which allows billing analysts to flag accounts with unusually high midday usage — a pattern consistent with restricted-hours irrigation.

If you receive a citation under a Stage 2 declaration and believe it was issued in error — for example, because you were using exempt drip irrigation or were within a registered establishment window for new sod — Central Arkansas Water has a customer service review process. Call 501-377-1242 within 10 business days of the citation to request a review. Documented exemptions (registration confirmations, drip system invoices) significantly strengthen an appeal.

Other outdoor water rules

Beyond lawn irrigation, Central Arkansas Water's conservation advisory addresses several other outdoor uses. The following rules apply under the current Stage 1 voluntary guidance and would become mandatory under a Stage 2 declaration:

• Car washing: Washing vehicles at home is discouraged during midday hours (10:00 AM – 5:00 PM). Commercial car washes that recycle water are not restricted.
• Pressure washing: Pressure washing driveways, decks, and exterior surfaces for non-safety purposes is discouraged during Stage 1 and would be restricted under Stage 2.
• Swimming pools: Initial pool filling is permitted, but topping off pools unnecessarily is discouraged. Pool covers are strongly encouraged to reduce the significant evaporation rates common during Little Rock's hot, humid summers.
• Ornamental fountains: Decorative fountains and water features not equipped with recirculating pumps should be turned off. Recirculating fountain systems are exempt.
• Construction water: Dust suppression and construction site water use must use the minimum amount necessary. Contractors operating in Little Rock's active development corridors along Interstate 430 and Chenal Parkway should confirm compliance with Central Arkansas Water before beginning large-scale grading projects during dry periods.
• Restaurants: Serving water only upon request is a voluntary courtesy measure under Stage 1.

Little Rock's water supply and source

Little Rock's municipal water supply is drawn primarily from the Arkansas River, which runs through the heart of the metro area. Central Arkansas Water operates two major treatment facilities that process this surface water supply: the Ozark Point Water Treatment Plant and the Maumelle Water Treatment Plant, the latter of which draws from Lake Maumelle — a 8,900-acre reservoir in the Ouachita foothills west of Little Rock that serves as the primary finished-water storage and supply source for the system.

Lake Maumelle is a protected watershed reservoir managed cooperatively by Central Arkansas Water and the City of Little Rock. The watershed covering roughly 108,000 acres is subject to strict land-use controls that prohibit most development, making it one of the better-protected municipal water sources in the South. The lake has a storage capacity of approximately 120,000 acre-feet and is the backbone of the water supply for more than 400,000 people in the Central Arkansas service area.

A secondary supply source is the Arkansas River itself, processed through the Ozark Point facility in downtown Little Rock. The river supply is used to supplement Lake Maumelle during high-demand periods or when lake levels are affected by drought. The Arkansas River's flow through the region is partially regulated by the U.S. Army Corps of Engineers through the McClellan-Kerr Arkansas River Navigation System, which affects minimum flow levels during dry years.

Groundwater plays a minor supplemental role in some outlying portions of the Central Arkansas Water service territory, but the system is not groundwater-dependent in the way that some other Arkansas communities are. Drought impacts on the system manifest primarily as reduced inflow to Lake Maumelle and increased turbidity in Arkansas River intakes after storm events — both of which affect treatment plant capacity and operating costs.

HOA rules during water restrictions

Arkansas does not have a specific state statute equivalent to Colorado's CRS § 37-60-126 or Florida's FS § 720.3075 that explicitly prohibits HOAs from fining homeowners for brown lawns during declared water restrictions. However, under Arkansas common law and general HOA enforcement principles, an HOA's ability to fine a homeowner for lawn appearance is substantially weakened when a government-declared water restriction is the direct cause of the lawn's condition.

If your Little Rock HOA is threatening action over your lawn's appearance during the Central Arkansas Water Stage 1 Advisory period, you have a practical argument even without a dedicated statute: the advisory represents a public utility's recommendation, and compliance with it is a reasonable and prudent action. If Central Arkansas Water issues a formal Stage 2 mandatory restriction, that order from a public utility supersedes HOA covenants under Arkansas utility law principles.

The following is a template letter you can adapt and send to your HOA board:

"Dear [HOA Name] Board of Directors: I am writing in response to the notice regarding the appearance of my lawn at [your address]. I want to inform the Board that I am currently following the voluntary Stage 1 conservation advisory issued by Central Arkansas Water (Little Rock Water Works), which recommends limiting outdoor irrigation to three days per week with no midday watering between 10:00 AM and 5:00 PM. Compliance with this advisory is the direct reason my lawn is showing drought stress. I am committed to restoring turf appearance as soon as conditions allow full irrigation. Please confirm that no fines will be assessed while the Central Arkansas Water advisory is in effect. You may verify the advisory at carkw.com or by calling 501-377-1242."

Keep a copy of any communication from Central Arkansas Water confirming the advisory as documentation if the HOA dispute escalates.

Lawn survival guide for Little Rock

Little Rock sits squarely in the transition zone — a climate band where both warm-season and cool-season grasses can survive, but where summer heat stresses cool-season varieties and winter cold limits warm-season growth. The grasses most commonly found in Little Rock lawns are Tall Fescue, Bermudagrass, Zoysiagrass, and to a lesser extent hybrid Bermuda varieties bred for transition-zone performance.

During Little Rock's peak heat period — typically late June through August, when temperatures regularly exceed 95°F and humidity stays high — Bermudagrass and Zoysiagrass are the most resilient choices under restricted watering. Both can go into protective dormancy when water is withheld and recover once irrigation resumes. Tall Fescue, which is common in shaded Little Rock yards and in the cooler neighborhoods along Pinnacle Mountain's eastern foothills, is more vulnerable: extended dormancy can kill Fescue crowns, especially on south-facing slopes with reflected heat. Prioritize your Tall Fescue areas during your three allowed watering days and consider raising your mower height to 3.5–4 inches to reduce moisture stress.

Little Rock's humid subtropical climate also creates fungal pressure — brown patch (Rhizoctonia solani) is a persistent problem in Tall Fescue and Zoysia lawns, particularly when overnight temperatures stay above 70°F and lawns are watered in the evening. If you must water after 5:00 PM under the advisory schedule, aim to finish early enough that turf can dry somewhat before midnight. Morning watering (before 10:00 AM) is always preferable from a disease management standpoint and is fully compliant with Central Arkansas Water's advisory guidance.

Frequently asked questions

What days can I water my lawn at an odd-numbered address in Little Rock right now?

If your address ends in an odd digit (1, 3, 5, 7, or 9), Central Arkansas Water's Stage 1 voluntary advisory recommends watering on Monday, Wednesday, and Friday only. You should water before 10:00 AM or after 5:00 PM to reduce evaporation. These are voluntary guidelines — there are currently no fines for non-compliance — but following them helps prevent a mandatory Stage 2 restriction from being declared.

Is the current water restriction in Little Rock mandatory or voluntary?

It is voluntary. Central Arkansas Water has issued a Stage 1 Advisory as of April 2026, which is a recommendation to reduce irrigation frequency — not a legally enforceable order. Fines and enforcement only begin if Central Arkansas Water formally declares a Stage 2 mandatory restriction. You can check the current stage at carkw.com or call 501-377-1242 to confirm status before assuming conditions haven't changed.

Can I wash my car at home in Little Rock right now?

Yes, home car washing is currently permitted, but Central Arkansas Water discourages it during midday hours between 10:00 AM and 5:00 PM. Using a bucket and a nozzle with a shutoff valve is the preferred approach. Commercial car washes that recirculate water are unrestricted. If a Stage 2 restriction is declared, home vehicle washing rules may become more specific — check carkw.com for updates.

Does Central Arkansas Water use smart meters to detect watering violations?

Yes. Central Arkansas Water has installed automated meter infrastructure (AMI) across most of its Little Rock service area. These smart meters report usage data at short intervals, allowing the utility's billing and compliance staff to identify accounts with high water use during restricted midday hours. If a Stage 2 restriction is declared, smart meter data is one of the tools used alongside complaint reports to identify potential violations. This means that consistently running irrigation at noon will be visible in your account data even without a neighbor calling in a complaint.

I just installed new sod in my Little Rock backyard. Do restrictions apply to me?

New sod installations qualify for a 21-day establishment variance from Central Arkansas Water, which allows more frequent watering than the standard advisory schedule permits. You must register for this variance with Central Arkansas Water before or immediately after installation — do not assume it applies automatically. Contact them at 501-377-1242 or through the customer portal at carkw.com to get your variance on file before a Stage 2 declaration potentially makes exemption documentation more important.

Does Lake Maumelle's level affect when restrictions are declared in Little Rock?

Yes. Lake Maumelle is the primary stored water supply for Central Arkansas Water, and its level — along with Arkansas River intake conditions and system demand data — informs the utility's decisions about moving between advisory stages. Central Arkansas Water does not publish a publicly visible lake level dashboard comparable to some western utilities, but drought monitoring through the Arkansas Natural Resources Commission and the U.S. Drought Monitor for Pulaski County feeds into the utility's internal staging criteria. A significant drop in Lake Maumelle storage during a dry summer is one of the primary triggers for escalating from Stage 1 to Stage 2.

What rebates or programs does Central Arkansas Water offer for water-efficient landscaping?

Central Arkansas Water periodically offers customer conservation incentive programs, including rebates for high-efficiency irrigation controllers (smart timers) and water audits for residential customers. Program availability and rebate amounts change based on the utility's conservation budget cycle. Contact Central Arkansas Water directly at 501-377-1242 or visit carkw.com to ask about currently active rebate programs — the website's conservation section lists any open enrollment periods for irrigation efficiency incentives applicable to Little Rock residential accounts.

Can Little Rock restaurants still serve water to customers during the Stage 1 Advisory?

Yes. Under the current voluntary Stage 1 Advisory, restaurants in Little Rock are encouraged — but not required — to serve water only upon customer request rather than automatically filling glasses at every table setting. This is a courtesy measure, not an enforcement item. If Central Arkansas Water escalates to a Stage 2 mandatory restriction, the water-on-request rule for food service establishments may become enforceable. Restaurant operators on accounts with Central Arkansas Water should review the Stage 2 conditions at carkw.com so they are not caught off guard by a mid-season declaration.

What time can I water in Little Rock?

Watering is allowed Before 10:00 AM and After 5:00 PM. Watering outside these hours is a violation even on your assigned day.

When will water restrictions end in Little Rock?

Current No Active Restrictions restrictions are in effect through December 31, 2026. Monitor https://carkw.com for the latest status.

Can I hand water during Little Rock water restrictions?

Yes. Hand watering with a hose fitted with a shut-off nozzle is generally allowed on any day during permitted hours. Drip irrigation and soaker hoses are also typically exempt from the day-of-week schedule. Confirm specifics with Central Arkansas Water / Little Rock Water Works.
