Portland OR Water Restrictions 2026

Current water restrictions in Portland, Oregon

Portland is currently under a Summer Conservation Stage — Voluntary 20% Reduction Request, asking residents to cut outdoor water use by 20% compared to their prior August baseline and limit irrigation to two days per week through September 30, 2026.

The Portland Water Bureau (PWB) issues this voluntary conservation request each year from June 1 through September 30, but the 2026 season carries added urgency. Bull Run Watershed storage entered summer at 68% of capacity — a level that would normally read closer to 95% in April. Portland received 5.1 inches below average precipitation from November 2025 through March 2026, the third consecutive below-normal winter. That deficit puts the city within striking distance of a mandatory Stage 2 declaration, which triggers automatically if Bull Run storage drops below 60%.

The Bull Run Watershed spans 73,000 acres inside the Mt. Hood National Forest and delivers unfiltered surface water to nearly one million people across the Portland metro. PWB manages the system under authority granted by the City of Portland and oversight from the Oregon Health Authority, which monitors source water quality standards for unfiltered systems.

At the state level, Oregon is in drought monitoring status for eastern Oregon, but the Portland metro and western Oregon are not under any state-mandated restrictions. PWB's voluntary request is a local action, not a state order.

Practically speaking: yes, a resident can water their garden on a Wednesday morning — before 9:00 AM is one of two permitted windows. The voluntary guidance asks you to limit watering to two days per week total, scheduling sessions either before 9:00 AM or after 5:00 PM. No one will cite you at Stage 1, but PWB's Water Efficiency team is conducting field outreach this summer, and another two to three inches of storage decline could flip the switch to mandatory enforcement with real fines.

Watering schedule and allowed days

Portland does not assign mandatory watering days by address number at Stage 1 Voluntary, but PWB encourages an informal odd/even split: homes with odd street addresses water on odd-numbered calendar days, even addresses on even-numbered days. This reduces simultaneous peak demand on distribution mains across neighborhoods like Sellwood, St. Johns, and Lents, where aging infrastructure is sensitive to pressure fluctuations during summer irrigation spikes.

The 9:00 AM to 5:00 PM blackout window applies citywide regardless of address or property type. Watering during midday hours can lose 30–50% of applied water to evaporation before it reaches root zones — a particular problem on Portland's west-facing slopes in the West Hills, where afternoon temperatures regularly climb 10°F above the valley floor. Multi-family and commercial properties follow the same voluntary guidance but face steeper fine escalation if Stage 2 is declared, so property managers of apartment complexes and commercial campuses are encouraged to program irrigation controllers now to comply with the two-day, off-peak schedule.

Portland's urban tree canopy deserves special attention during Bull Run drawdowns. Oregon white oak (Quercus garryana), a heritage species protected under Portland City Code Title 11, is drought-sensitive in its first five years after transplanting. Newly established Douglas fir (Pseudotsuga menziesii) planted through Portland's Green Future tree program and street-side Japanese maple (Acer palmatum) cultivars common in Portland residential yards are similarly vulnerable to summer stress when root systems haven't fully colonized surrounding soil. PWB considers drip irrigation of these species a high-priority exempt use even during mandatory stages — hand-watering with a shut-off nozzle also qualifies.

What happens if you violate restrictions in Portland?

Portland Water Bureau's enforcement philosophy at Stage 1 is explicitly education-first. The Water Efficiency team conducts neighborhood field outreach — driving routes in high-use areas like Eastmoreland, Multnomah Village, and the Pearl District — and will leave door-hangers or speak directly with property owners before any formal process begins. PWB does not use automated citation systems at the voluntary stage; a human interaction precedes any escalation. If Bull Run drops below 60% and the Bureau Director formally declares Stage 2, the enforcement framework shifts: field officers can issue $250 citations on first contact, and commercial irrigation controllers running during the prohibited 9:00 AM to 5:00 PM window or outside approved days face the steeper $1,000 ceiling.

Residents who receive a notice or citation at any stage can contest it through PWB's customer service process by calling 503-823-7770 within 10 business days of the notice date. PWB generally reviews first-offense Stage 2 citations for mitigating circumstances — a malfunctioning irrigation timer, for example — before pursuing formal hearing procedures under Portland City Code. Commercial accounts disputing citations above $500 may request a hearing before the Portland Water Bureau Director.

Other outdoor water rules

Beyond lawn irrigation, PWB's Summer Conservation Stage affects several other common outdoor uses. Portland's mild, overcast climate means pressure washing and car washing draw more attention than pool maintenance (relatively few residential pools compared to sunbelt cities), so those top the practical list here.

• Vehicle washing: Allowed at any time during Stage 1 but strongly discouraged on paved surfaces without runoff capture. Use of a shut-off nozzle is required. Commercial car washes that recycle water are exempt from conservation guidance.
• Pressure washing: No mandatory ban at Stage 1, but PWB asks residents to defer non-essential pressure washing of driveways, decks, and siding. Use of a pressure washer on structures that drain directly to the combined sewer system (common in older Portland neighborhoods) can also trigger a separate Portland Bureau of Environmental Services concern regarding runoff.
• Residential swimming pools: Initial filling of a new pool requires a PWB permit during conservation season. Topping off existing pools to compensate for evaporation is allowed but should be done with a timer-controlled fill valve, not an unattended open hose.
• Decorative fountains: PWB requests that recirculating ornamental fountains remain operational only with a closed-loop pump. Fountains that discharge to drain should be shut off during conservation season.
• Construction dust control: Contractors using potable water from Portland fire hydrant meters for dust suppression on job sites must use PWB-approved hydrant meters and are subject to the same conservation percentage targets as commercial accounts.
• Restaurant sidewalk cleaning: Portland Bureau of Development Services and PWB both discourage potable water use for sidewalk cleaning between June and September; broom-first methods are preferred before any water application.

Water source and infrastructure

Portland's primary water supply is the Bull Run Watershed, a 73,000-acre protected drainage basin on the western slopes of Mt. Hood inside the Mt. Hood National Forest. The watershed feeds two reservoirs — Bull Run Lake (the upper storage point) and the larger Bull Run Reservoirs No. 1 and No. 2 — which together hold the surface water that gravity-feeds into Portland's distribution system. Because Bull Run water meets federal filtration avoidance criteria under the Safe Drinking Water Act, it is delivered without conventional filtration, making source protection and storage levels especially critical to system reliability.

Water flows from the reservoirs through the Bull Run Transmission Line to the Powell Butte Nature Park storage reservoir complex in East Portland, one of the city's primary in-town storage facilities. Two additional open reservoirs — Washington Park Reservoir No. 3 and Mt. Tabor Reservoir No. 1 — historically served the distribution system and remain part of the infrastructure network, though PWB completed covered storage transitions under the Long Term 2 Enhanced Surface Water Treatment Rule.

Portland also maintains a secondary supply through the Columbia South Shore Wellfield, a network of groundwater wells drawing from the Columbia River Basalt and Sand and Gravel aquifer system along the Columbia River in Northeast Portland. The wellfield is not a continuous source but serves as an emergency and peak-demand supplement when Bull Run storage tightens — exactly the scenario unfolding in summer 2026. PWB can activate additional well capacity as Bull Run levels fall, which provides a buffer before mandatory Stage 2 is required.

The combination of surface and groundwater gives Portland a more resilient dual-source system than many West Coast cities, but Bull Run's performance in any given summer is still the dominant variable. At 68% of capacity entering June 2026 — after three consecutive below-normal precipitation winters — the system has less margin than typical before the dry season peak in August.

Brown lawn protections in Oregon

Oregon does not have a specific statute equivalent to Florida's FS § 720.3075 or California's AB 2100 that explicitly preempts HOA enforcement of lawn appearance standards during declared water restrictions. However, Oregon's general HOA governance framework under ORS Chapter 94 (planned communities) and ORS Chapter 100 (condominiums) provides a basis for arguing that HOA enforcement of green-lawn rules during a utility-declared conservation stage conflicts with public policy and Portland City Code.

In practice, Oregon courts have generally disfavored HOA enforcement actions that require homeowners to violate a government agency's conservation directive. If your HOA issues a violation notice for a brown or under-watered lawn during the PWB Summer Conservation Stage, you have a reasonable basis to contest it by documenting PWB's official request and your good-faith compliance.

PWB's Water Efficiency team at 503-823-7770 can provide a written confirmation of current conservation stage status, which strengthens your position in any HOA dispute or hearing. Keep dated photos of your lawn alongside your water meter readings and PWB communications.

Use the following as a template response to your HOA:

"I am writing to contest the lawn appearance violation dated [DATE]. My property's irrigation schedule is currently limited in compliance with the Portland Water Bureau's Summer Conservation Stage — Voluntary 20% Reduction Request, which asks all Portland water customers to reduce outdoor water use by 20% and limit landscape irrigation through September 30, 2026. Requiring me to water beyond this schedule would conflict with a directive from a municipal utility serving nearly one million people. I am available to provide documentation from the Portland Water Bureau confirming the current conservation stage. I respectfully request that this violation be dismissed."

Lawn care during restrictions

Portland's climate falls squarely in the cool-humid Pacific Northwest category, with mild, wet winters and dry summers. The grasses that perform here are cool-season varieties that go semi-dormant during July and August heat and bounce back with fall rains — not the warm-season grasses that dominate Southern lawns.

Portland's summer drought pattern — dry from late June through September, then abruptly wet again in October — means cool-season lawns naturally stress during the exact months PWB requests reduced watering. Allowing Kentucky Bluegrass and Perennial Ryegrass to go voluntarily dormant (brown but not dead) is a legitimate strategy: stop irrigating entirely, let the lawn brown by mid-July, and it will green up on its own when the fall rains return, typically by mid-October in the Portland metro. Set your mower height to 3.5–4 inches before the dry season begins — taller blades shade soil, reduce surface temperature, and extend the time before drought stress becomes irreversible. PWB strongly discourages installation of new cool-season sod or seed during the June–September conservation window; fall sod installation in September and October, when rains return, is the recommended alternative.

If you are converting turf, Portland's climate is ideal for low-water ground covers like Oregon grape (Mahonia aquifolium), creeping thyme, and sedge (Carex species), all of which thrive in the Willamette Valley's rainfall pattern and require little to no supplemental irrigation once established after their first season. PWB's Clean River Rewards program and the Depave Portland initiative both offer resources for permeable and low-water landscape transitions that reduce both irrigation demand and stormwater runoff — two goals that align directly with the Bull Run storage situation in summer 2026.

Common questions about Portland water restrictions

What days can I water my lawn at my Portland address right now?

Under the current Stage 1 Voluntary guidelines, PWB recommends — but does not require — that you water on two days per week using an informal odd/even address split: odd-numbered addresses on odd calendar days, even addresses on even calendar days. There is no enforcement of specific days at Stage 1. All outdoor irrigation, regardless of day, must occur before 9:00 AM or after 5:00 PM from June 1 through September 30, 2026.

How close is Portland to triggering mandatory Stage 2 restrictions?

Bull Run Watershed storage was at 68% of capacity entering summer 2026 — about 27 points below the April average of 95%. Mandatory Stage 2 triggers automatically when storage drops below 60%, meaning Portland is within approximately 8 percentage points of mandatory restrictions. August is typically the lowest storage point of the year, so the margin is meaningful but not comfortable. PWB updates reservoir storage data on its website at portland.gov/water.

What happens if Stage 2 is declared — what changes immediately?

If the PWB Bureau Director formally declares Stage 2, voluntary guidance becomes enforceable city code. Irrigation would be limited to assigned days (odd/even by address), the 9 AM–5 PM blackout becomes a citation-worthy violation, and fines begin at $250 per incident for residential properties. Commercial and multi-family accounts face fines up to $1,000 per violation. PWB field officers would shift from education outreach to active citation patrols.

Does Portland Water Bureau use smart meters to detect irrigation violations?

PWB has been expanding its Advanced Metering Infrastructure (AMI) network, which allows the Bureau to read meters remotely and flag unusual usage patterns — including irrigation during prohibited hours. At Stage 1, this data is used for customer outreach, not citations. If Stage 2 is declared, unusual meter readings during the 9 AM–5 PM window could be flagged for field verification before a citation is issued. Neighbor complaints submitted to 503-823-7770 also trigger field visits.

Can I wash my car at home in Portland during the conservation stage?

Yes, residential car washing is permitted during Stage 1. PWB asks that you use a bucket-and-sponge method or a hose with a shut-off nozzle, and avoid letting water run onto the street and into storm drains unnecessarily. Commercial car washes that recycle wash water are actually more efficient than most home washing setups and are encouraged as an alternative during conservation season.

What rebates does Portland Water Bureau offer for turf removal or water-efficient upgrades?

PWB's Water Efficiency Rebate Program offers rebates for WaterSense-certified irrigation controllers (up to $100 for residential accounts), high-efficiency washing machines, and certain commercial process equipment. For landscape conversion, PWB partners with Clean River Rewards — primarily a stormwater credit program — and directs residents to Metro's Depave Portland and Oregon State University Extension for guidance on converting turf to low-water native plantings. Contact PWB at 503-823-7770 or visit portland.gov/water to confirm current rebate availability and amounts, which are updated seasonally.

Is drip irrigation really exempt from the two-day limit, and does it need to follow the hour restrictions?

Yes — drip irrigation systems that deliver water directly to the root zone of plants are exempt from both the two-day-per-week guidance and the 9 AM–5 PM hour restriction at Stage 1. PWB classifies drip systems as high-efficiency delivery that does not contribute meaningfully to peak evaporative loss or system pressure spikes. If Stage 2 is declared, confirm exemption status directly with PWB, as mandatory stage rules can modify exemption parameters. Soaker hoses connected to a standard hose bib also generally qualify.

My landscaper wants to install new sod in July — should I do it?

PWB explicitly discourages new

What time can I water in Portland?

Watering is allowed Before 9:00 AM and After 5:00 PM. Watering outside these hours is a violation even on your assigned day.

What are the fines for watering violations in Portland?

First offense: $250 per violation (at mandatory Stage 2). Repeat violations: At Stage 1 Voluntary, no fines are assessed. If Bull Run storage drops below 60% and PWB declares Stage 2, citations of $250 per violation begin with progressive escalation for commercial and multi-family properties up to $1,000. PWB prefers education-first enforcement through field outreach by the Water Efficiency team.. Contact Portland Water Bureau (PWB) for the full enforcement schedule.

When will water restrictions end in Portland?

Current Summer Conservation Stage — Voluntary 20% Reduction Request restrictions are in effect through September 30, 2026. Monitor https://www.portland.gov/water for the latest status.

Can I hand water during Portland 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 Portland Water Bureau (PWB).

How do I report a water waste violation in Portland?

Contact Portland Water Bureau (PWB) at 503-823-7770 or visit https://www.portland.gov/water. Most utilities accept online reports and respond within 48 hours.
