Colorado Water Restrictions 2026: What Erie and Longmont Homeowners Need to Know

2026 is a rough water year. Snowpack on the Front Range hit record lows this winter, and every water district from Fort Collins to Denver is tightening things up. If you've got a lawn and garden in Erie, Longmont, Louisville, or Lafayette, you need to know the rules before you turn on your sprinklers.

Here's what's happening and how to keep your yard alive without getting fined or wasting money.

Erie Watering Rules for 2026

The Town of Erie operates on a voluntary two-day-per-week watering schedule during normal years. In 2026, with drought conditions in effect, expect that to shift earlier and get enforced more strictly.

Here's what Erie residents should plan for:

• Two days per week based on your address (odd addresses on certain days, even on others)
• No watering between 10am and 6pm during summer months
• No watering on Mondays (system-wide conservation day in some years)
• Restrictions typically kick in May 1 and run through September

Erie's water comes from a mix of sources, and during drought years, the town has historically moved from voluntary to mandatory restrictions. If 2026 gets worse through summer, expect stricter rules and actual enforcement.

Keep an eye on the Town of Erie's water page for updates. They'll post changes there before anywhere else.

Longmont Watering Rules for 2026

Longmont is already at Drought Watch level heading into spring. That's a step above normal and comes with real rules:

• No outdoor watering before May 1 (this is enforced)
• Twice per week maximum once the season starts
• Only before 10am or after 6pm
• Assigned watering days based on address
• No watering on Fridays (conservation day)
• Mandatory for all residential and commercial properties

Longmont has water cops. They drive neighborhoods and issue warnings first, then fines. A first violation is usually a warning letter. After that, fines range from $50 to $500 depending on how many times you're caught.

The city adjusts restriction levels throughout summer. If things get worse, they can move to Drought Alert or Drought Emergency, which further limits days and hours.

What This Means for Your Lawn

Two days a week with no midday watering sounds rough. But here's the thing: most lawns in Northern Colorado only need about 1 to 1.5 inches of water per week. You can absolutely deliver that in two watering days if your system is set up right.

The key is getting every drop into the soil instead of losing it to evaporation, runoff, or overspray.

How to Stay Green Within the Rules

Use Cycle and Soak

Don't run each zone for 20 minutes straight. Colorado clay can only absorb about 0.2 inches per hour before it starts running off. Split your watering into shorter cycles with breaks in between.

Example: Instead of running Zone 1 for 20 minutes, run it for 7 minutes, wait 30 minutes, run it for 7 minutes again, wait 30 minutes, then run it a final 6 minutes. Same total water, way better absorption.

Every smart controller does this automatically. On a basic timer, set multiple start times.

Water Early (Really Early)

The 6am-10am window isn't just a rule. It's the best time to water anyway. Temperatures are cool, wind is calm, and evaporation is at its lowest. If you can start at 5am or 6am, even better. Your neighbors are sleeping and won't notice the sprinklers.

Get a Smart Controller

A Rachio 3 or Hunter Hydrawise does a few things that matter during drought restrictions:

• Automatically skips watering when rain is in the forecast
• Adjusts run times based on temperature, wind, and humidity
• Enforces your local watering schedule so you never accidentally run on the wrong day
• Tracks your water use so you can see if you're improving

Many homeowners save 30-40% on water with a smart controller, which means you can stay green with less.

Fix Your System First

Before the season starts, make sure your sprinklers are actually working right. One broken head gushing water wastes more in a week than a properly running system uses in a month. Heads spraying sidewalks, misting into the wind, or running on zones with underground leaks all burn through your limited watering days without helping your lawn.

A quick system checkup in April or May saves water all summer long.

Rebates and Incentives

Here's the good news: because of drought conditions, local water districts are putting more money toward rebates for water-saving upgrades.

• Smart controller rebates: $50-$150 from most Front Range water providers
• Nozzle upgrade rebates: Some districts offer rebates for switching to high-efficiency nozzles
• Xeriscaping and turf replacement: Programs that pay you to replace grass with drought-tolerant plants

We keep a running list of available rebates for Erie, Longmont, Louisville, and Lafayette. The amounts and programs change year to year, so check with us or your water provider before buying.

What If Restrictions Get Tighter?

If we move into full drought emergency, watering could drop to once a week or get banned entirely for non-established landscapes. Here's how to prepare:

• Prioritize your trees. Trees are the most valuable and hardest to replace landscaping on your property. If you can only water one thing, water your trees. Hand watering with a hose is usually allowed even during strict restrictions.
• Let the lawn go dormant. Kentucky bluegrass goes brown in drought but it's not dead. It'll come back when water returns. Don't waste restricted watering days trying to keep it green.
• Focus on high-value beds. Flower beds, vegetable gardens, and newly planted areas need water. Drip irrigation on these areas uses a fraction of what sprinklers use.

The Bottom Line

2026 is going to test every lawn on the Front Range. The homeowners who come out ahead will be the ones with efficient systems, smart controllers, and watering schedules that put every drop to work.
