Allowed Watering Hours

Before 8:00 AMAfter 6:00 PM

No outdoor irrigation between 8:00 AM and 6:00 PM. NO outdoor watering on Mondays, Thursdays, or Fridays under any circumstance. Stockton's framework is an unusual 2-days-per-week schedule that excludes three full days entirely – the recommended window is 2:00 AM to 6:00 AM when winds are lowest and evaporation losses are minimal. The schedule is permanent under Stockton Municipal Code Chapter 13.28, not a temporary drought response.

Still Allowed

💧 Hand Watering

Allowed with shut-off nozzle. Hours: Any day with a shut-off nozzle.

🌿 Drip Irrigation

Exempt from day-of-week limits. Must follow allowed hours.

Fines & Enforcement

$100 per day for continuing violations after notice

City of Stockton Municipal Utilities Department issues a notice of violation on first detection. Continuing violations after notice draw a $100 per day fine or surcharge added to the monthly utility bill. Commercial properties face up to $500 per day. Pool draining or refilling between June 1 and October 1 requires written authorization from Municipal Utilities – unauthorized pool fills carry their own enforcement penalties.

🏠 HOA Rules During Restrictions

California Water Code §10631.5 and Civil Code §4735 prohibit HOA fines for drought-compliant brown lawns during a declared shortage and protect homeowners who reduce irrigation. Stockton's permanent mandatory conservation framework qualifies as the state-recognized trigger for these protections. Document the Stockton Municipal Code Chapter 13.28 ordinance plus the §10631.5 / §4735 citations if your HOA 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 City of Stockton – Municipal Utilities Department. 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

Stockton sits at the eastern edge of the Sacramento–San Joaquin Delta, one of the most hydrologically complex water systems in the United States. The city is served by the City of Stockton Municipal Utilities Department, which operates an unusual permanent mandatory water-conservation framework under Stockton Municipal Code Chapter 13.28 – the rules apply year-round regardless of drought stage, with stage escalation possible if regional supplies tighten further.

Stockton's source water mix

  • Local groundwater from the San Joaquin Valley aquifer system
  • Delta surface water diverted through the Stockton East Water District (SEWD) canal system
  • State Water Project deliveries through the Delta–Mendota Canal

Delta water quality is a chronic operational challenge. Saltwater intrusion from San Francisco Bay during dry years, agricultural runoff from upstream Central Valley operations, and urban runoff all stress Delta water-treatment infrastructure. Stockton has invested heavily in water treatment to handle Delta source water, and during dry years increases reliance on groundwater pumping.

The permanent 2-days-per-week schedule (Tuesday/Saturday for odd addresses; Wednesday/Sunday for even) excludes Monday, Thursday, and Friday entirely from outdoor watering – an unusually restrictive pattern even among California utilities. The 8 AM – 6 PM blackout is also tighter than most peer cities. The framework was originally adopted during the 2012–2017 mega-drought and made permanent rather than rescinded.

San Joaquin County agriculture is one of the largest groundwater users in the state. Stockton's municipal supply benefits from groundwater management under SGMA but is exposed to the same regional aquifer-decline trajectory as the surrounding agricultural region.

Rainfall Deficit: Sierra snowpack feeding the Delta variable across recent winters · SWP allocation 30% · groundwater levels under SGMA monitoring

This deficit has accumulated over the current water year and represents a significant departure from historical averages for the Stockton area. Water supply reservoirs and aquifer levels are well below seasonal targets, necessitating mandatory conservation measures.

How to Keep Your Lawn Alive During Stockton Water Restrictions

11 tips tailored for Stockton homeowners during City of Stockton Mandatory Water Conservation restrictions.

Stockton's permanent schedule is unusual: 2 days per week (odd Tuesday/Saturday, even Wednesday/Sunday), with NO outdoor watering Monday, Thursday, or Friday. Programme your controller to reflect this.

Recommended window: 2:00 AM to 6:00 AM when winds are calm and evaporation losses are minimal – Stockton summer winds pick up after 8 AM.

Central Valley summers regularly hit 95–105°F July–September – warm-season Bermuda is the most schedule-friendly grass; tall fescue browns severely.

Stockton's clay soils shed water in under 90 seconds of continuous spray – cycle-and-soak (3 min on, 20-minute pause, 3 min on) prevents runoff.

Mulch ornamental beds 3 inches deep with arborist wood chips – bare soil in the Central Valley summer loses 0.5+ inches of moisture per day.

Pool draining or refilling between June 1 and October 1 requires written authorization from Stockton Municipal Utilities – submit the request in advance.

Drip-irrigate trees, shrubs, and vegetable beds – drip is exempt from day-of-week and time-of-day limits under Stockton's framework.

Install a smart controller with a rain sensor – Stockton Municipal Utilities offers $50–$80 rebates on WaterSense-labeled controllers.

Skip your scheduled cycle after 0.5 inch of rainfall in the prior 48 hours; California requires rain sensors on systems installed after 1991.

Stockton's turf-replacement rebate ($1–$2/sq ft up to 1,500 sq ft) is the primary conversion incentive – verify current funding at stocktonca.gov.

Track monthly use at stocktonca.gov 'My Account' – high-use months trigger automatic notice-of-violation reviews under Chapter 13.28.

Stockton Water Restriction FAQs

When will water restrictions end in Stockton?
The current City of Stockton Mandatory Water Conservation restrictions in Stockton are effective from Year-round mandatory conservation framework (Stockton Municipal Code Ch. 13.28) through Permanent ordinance · stages may escalate based on regional supply. However, the restrictions may be extended if drought conditions persist or eased if significant rainfall improves water supply levels. Monitor the City of Stockton – Municipal Utilities Department (Water Utility) website for updates.
I'm near the Delta – why are restrictions in place if water is right here?
Delta water is plentiful in volume but constrained in operational availability. The Sacramento–San Joaquin Delta is the hub of California's water system: the State Water Project and Central Valley Project both pull water out of the Delta to deliver to the rest of the state. Environmental flow requirements (to protect Delta smelt, salmon migration, and water-quality standards in San Francisco Bay), saltwater intrusion controls, and competing senior water rights all limit how much Delta water any individual user – including Stockton – can divert. During dry years, Delta diversions are cut even though the water is physically present. Stockton's permanent 2-days-per-week schedule reflects this structural constraint plus the city's historical decision after the 2012–2017 drought to maintain mandatory conservation as a permanent framework rather than ratchet back to voluntary status. Local groundwater is also stressed under SGMA – over-pumping the local aquifer would create regulatory and supply problems beyond the immediate water-availability issue.
Stockton vs Lodi vs Tracy – different rules for nearby San Joaquin cities?
Yes. San Joaquin County cities each have their own retail water utilities: City of Stockton Municipal Utilities (Stockton); City of Lodi Public Works (Lodi); City of Tracy Public Works Utilities (Tracy); City of Manteca Public Works (Manteca); City of Lathrop Municipal Services (Lathrop); and California Water Service Stockton District for some Stockton-area addresses. Stockton's permanent 2-days-per-week + 8 AM – 6 PM blackout + no Mon/Thu/Fri framework is among the more restrictive in the county. Lodi, Manteca, and Tracy each maintain their own framework – typically 2–3 days per week with different time-of-day windows. Cal Water's Stockton District (a small portion of city addresses on Cal Water rather than Municipal Utilities) follows Cal Water's CPUC-approved framework which is different from the city's. Always check the top of your water bill to identify your retail utility and follow that utility's specific rules.
Delta salinity – does that affect my tap water quality?
Indirectly. Delta water diverted to Stockton (via Stockton East Water District) and to State Water Project deliveries can become more saline during dry years when freshwater outflow to San Francisco Bay decreases – this allows ocean salt to push further upstream into the Delta. Stockton's water treatment plant has investment in technology to handle Delta source-water variability, and the blend with local groundwater and SWP supply typically keeps tap-water salinity well within drinking-water standards. During acute dry-year pulses, Stockton can shift the blend toward more groundwater (if levels permit) or toward more SWP-from-Delta-Mendota (which is also impacted but differently than direct Delta diversions). Tap water remains safe and within California Department of Drinking Water standards. The salinity issue is primarily an operational and cost concern for the utility, not a direct customer-facing issue. Long-term Delta restoration projects (state and federal) aim to reduce the structural exposure to salinity intrusion.
