Fort Collins CO Water Restrictions 2026

Current water restrictions in Fort Collins, Colorado

Fort Collins is currently under Stage 1 Mandatory restrictions, limiting outdoor irrigation to 2 assigned days per week as part of the broader Front Range drought response.

Fort Collins Utilities declared Stage 1 restrictions in response to drought conditions affecting the Poudre River basin and the city's broader water supply system. The restrictions are mandatory — not voluntary — meaning compliance is required, not merely encouraged. This action is part of a region-wide emergency response: over 20 Front Range cities are currently under mandatory watering schedules, with Colorado experiencing Stage 1 through Stage 4 drought conditions statewide.

The trigger for Stage 1 in Fort Collins is tied to supply and demand thresholds monitored by Fort Collins Utilities, the municipal authority responsible for water delivery and conservation enforcement in the city. Fort Collins Utilities operates under the City of Fort Collins and can be reached online at fcgov.com/utilities. The drought conditions driving these restrictions are consistent with what neighboring systems are experiencing — Denver Water declared Stage 1 on March 25, and Eagle River is currently at Stage 3.

Practically speaking: a resident cannot simply choose any day to water their lawn or garden. You are assigned two specific watering days based on your address, and you may only irrigate outside the 10 a.m.–6 p.m. window. So if your assigned days are Tuesday and Friday, you can water your garden on a Wednesday only if Wednesday is one of your assigned days — and only before 10 a.m. or after 6 p.m. Watering outside your assigned days or during restricted hours is a violation. These restrictions remain in effect until Fort Collins Utilities determines that supply conditions have sufficiently improved.

Your assigned watering schedule

Rule	Details
Days per week	2
Day assignment	2 assigned days based on address
Allowed hours	Before 10 a.m. or after 6 p.m. only
Hand watering	Exempt — shut-off nozzle required on hose
Drip irrigation	Exempt from day/time restrictions
New sod/seed	30-day establishment window available — register with Fort Collins Utilities before installing

In Fort Collins, your two assigned watering days are determined by your street address — typically odd-numbered addresses water on different days than even-numbered addresses. Confirm your specific assigned days by checking directly with Fort Collins Utilities, as assignments can vary by zone within the city. Do not assume you share the same schedule as a neighbor across the street.

Multi-family residential properties and commercial accounts follow the same two-day-per-week framework but may have separate zone-level assignments if the account is billed as a large commercial or irrigation-only meter. Property managers with multiple zones or buildings should contact Fort Collins Utilities directly to confirm assigned days for each metered account rather than applying a single schedule across an entire complex.

The 10 a.m.–6 p.m. restriction window is primarily an evaporation-reduction measure — midday watering along the Front Range during summer can lose a significant percentage of applied water before it reaches roots. Fort Collins homeowners with established trees should prioritize deep, slow watering during the permitted hours. Species that are particularly stressed during Front Range drought and deserve priority watering attention include blue spruce (Picea pungens), a native Colorado tree common in city landscapes; plains cottonwood (Populus deltoides), widely planted along drainage corridors in Fort Collins; and honeylocust (Gleditsia triacanthos), a frequent street tree throughout the city's older neighborhoods. These trees are far more difficult and expensive to replace than turf, and targeted slow-drip watering at their root zones is exempt from day-and-time restrictions.

Fines and penalties

Offense	Penalty
First violation	Written warning — no fine
Second violation	Monetary fine issued by Fort Collins Utilities
Subsequent violations	Escalating fines; continued non-compliance may result in flow restrictor installation

Fort Collins Utilities enforces Stage 1 restrictions through a combination of complaint-based reporting and field patrols by utility staff. The city's Advanced Metering Infrastructure (AMI) smart meter network enables Utilities staff to identify unusual usage patterns — including high-volume irrigation on off-days — without physically observing a property. Complaints submitted by neighbors or passersby are also logged and investigated, typically within a few business days depending on staff workload.

If you receive a warning or fine you believe was issued in error — for example, if you were using exempt drip irrigation or watering a newly seeded area under an approved establishment window — you can contest the notice by contacting Fort Collins Utilities directly through the customer service portal at fcgov.com/utilities. Document your irrigation method with photos and your registration confirmation if you enrolled for a new sod/seed exemption. Response times for appeals vary, but the first-offense warning policy gives most good-faith violators a path to resolution without financial penalty.

Other outdoor water rules

Stage 1 restrictions in Fort Collins extend beyond lawn irrigation. The following activities are subject to specific rules during the current mandatory stage:

• Vehicle washing: Washing cars, trucks, or recreational vehicles at home is restricted to assigned watering days only and must use a hose with an automatic shut-off nozzle. Commercial car washes that recirculate water are permitted without day restrictions.
• Ornamental fountains and water features: Decorative fountains must be equipped with a recirculating pump. Single-pass or flow-through ornamental water features that discharge to a drain are not permitted during Stage 1.
• Pool and hot tub filling: Initial filling of new pools is allowed with a permit from Fort Collins Utilities. Topping off existing pools to compensate for evaporation is permitted but should be minimized; pool covers are strongly encouraged to reduce ongoing water loss during the restriction period.
• Pressure washing: Pressure washing of hard surfaces such as driveways and patios is restricted to safety-related or health-required cleaning. Cosmetic cleaning of exterior surfaces is not permitted under Stage 1.
• Construction water: Dust suppression and compaction water at active construction sites requires coordination with Fort Collins Utilities; contractors should confirm compliance requirements directly with the city's development review process.
• Restaurants and commercial food service: Serving water to restaurant patrons only upon request is in effect — a standard conservation measure Fort Collins has implemented during prior restriction periods.

Fort Collins's water supply and source

Fort Collins draws its municipal water supply primarily from the Cache la Poudre River, which flows out of Rocky Mountain National Park and the Roosevelt National Forest through the Poudre Canyon before entering the city. The Poudre is Fort Collins's most critical raw water source, and its flows are closely monitored throughout the irrigation season.

The city supplements Poudre River diversions through several storage and transmission systems. Horsetooth Reservoir, located immediately west of the city in the foothills, is a major storage component — it receives water delivered via the Colorado-Big Thompson (C-BT) Project, operated by the Northern Colorado Water Conservancy District (NCWCD). The C-BT Project tunnels transmountain water from the Western Slope under the Continental Divide through the Alva B. Adams Tunnel, delivering it into the South Platte basin system that ultimately feeds Horsetooth. Fort Collins holds C-BT units entitling it to a share of this transmountain supply, which is critical during low Poudre River years.

Raw water from both sources is treated at the Water Treatment Facility on Mulberry Street, which has a treatment capacity sufficient for normal demand but operates under tighter margins during drought when raw water quality is also affected by lower river flows and increased sediment concentration.

Additionally, Fort Collins holds direct-flow water rights on the Poudre River dating back to the late 19th century, as well as storage rights in Joe Wright Reservoir and Peterson Lake in the upper Poudre basin. During drought years when Horsetooth storage drops and Poudre River flows decline due to reduced Rocky Mountain snowpack runoff, the city's supply buffer tightens — which is the direct cause of the current Stage 1 mandatory restrictions. The Northern Colorado Water Conservancy District's annual C-BT quota decisions significantly influence how much supplemental water Fort Collins can draw in any given season.

HOA rules during water restrictions

Colorado homeowners are protected from HOA enforcement actions related to lawn appearance during mandatory water restrictions under Colorado Revised Statutes § 37-60-126. This statute prohibits homeowners associations from fining or penalizing residents for landscape that fails to meet community standards when that failure is a direct result of compliance with a government-imposed water restriction order. Because Fort Collins is currently under Stage 1 Mandatory restrictions issued by Fort Collins Utilities, your HOA cannot legally penalize you for a brown or dormant lawn if you are watering only on your assigned days.

The protection applies specifically when the landscape condition results from following the restriction — not from general neglect unrelated to watering limits. Keep documentation: save your Fort Collins Utilities account statements showing your usage, note your assigned watering days, and photograph your lawn periodically. If your HOA sends a violation notice, respond in writing and cite CRS § 37-60-126 explicitly.

Use this template response to your HOA:

"This letter is to notify [HOA Name] that the current condition of my lawn at [address] is the direct result of my compliance with Fort Collins Utilities Stage 1 Mandatory water restrictions, currently in effect. Under Colorado Revised Statutes § 37-60-126, homeowners associations are prohibited from imposing fines or penalties for landscape conditions caused by adherence to government-mandated water restrictions. I am watering on my two assigned days outside the restricted 10 a.m.–6 p.m. window, in full compliance with Fort Collins Utilities requirements. Please suspend any pending violation notice and update your records accordingly."

Lawn survival guide for Fort Collins

Fort Collins sits on the Front Range at roughly 5,000 feet elevation, which means lawns here are composed almost entirely of cool-season grasses. Warm-season grasses that thrive in Kansas or Texas are largely unsuitable for this climate zone. The four grasses you will actually find in Fort Collins yards are:

Grass Type	Drought Tolerance	Dormancy Under Restriction	Recovery Speed
Kentucky Bluegrass	Low–Moderate	Goes dormant quickly; browning normal	Moderate — recovers well after rain returns
Tall Fescue	Moderate–High	Holds color longer than bluegrass	Good — deeper roots help
Buffalograss	Very High	Native; tolerates extended dry periods	Excellent — evolved for this climate
Blue Grama	Very High	Native; minimal irrigation needed	Excellent — highly drought adapted

The dominant lawn grass in Fort Collins is Kentucky Bluegrass, and it will go brown and dormant under a two-day-per-week schedule during a hot July or August. This is normal and not permanent — bluegrass can survive extended dormancy as long as it receives at least a small amount of water periodically. Raise your mowing height to at least 3 to 3.5 inches during restriction periods; taller grass shades its own root zone and retains soil moisture significantly longer between watering days. Avoid mowing when the lawn is already heat-stressed, and never remove more than one-third of the blade length in a single cutting.

Fort Collins's high altitude means intense UV exposure and low humidity, both of which accelerate evapotranspiration. Water deeply and infrequently on your two assigned days rather than applying shallow amounts — deep watering encourages root growth downward into cooler soil, which builds drought resilience. Homeowners who want to reduce long-term irrigation demand significantly should consider overseeding or converting sections of Kentucky Bluegrass to Buffalograss or Blue Grama, both of which are native to the Colorado Plains and require a fraction of the irrigation that bluegrass demands once established.

Frequently asked questions

What are my assigned watering days in Fort Collins right now?

Your two assigned watering days are determined by your street address number under the Fort Collins Utilities Stage 1 schedule. Odd and even address numbers are typically assigned to different day pairs to spread system demand across the week. Log in to your Fort Collins Utilities account at fcgov.com/utilities or contact customer service to confirm the exact days assigned to your specific address, as the schedule can differ between service zones within the city.

Can I water before 10 a.m. on my assigned days?

Yes — watering before 10 a.m. on your two assigned days is fully permitted and is actually the most efficient option. Early morning watering minimizes evaporation loss under Fort Collins's low-humidity conditions and gives turf and plants time to dry before nightfall, which reduces fungal pressure. The restricted window is 10 a.m. to 6 p.m. only; watering after 6 p.m. on an assigned day is also allowed.

Does Fort Collins Utilities use smart meters to detect watering violations?

Yes. Fort Collins Utilities has deployed an Advanced Metering Infrastructure (AMI) system across the city. These smart meters transmit hourly consumption data, which means Utilities staff can identify accounts showing significant irrigation water use on non-assigned days without any in-person observation. Unusual usage patterns — particularly spikes consistent with sprinkler system run times — can flag an account for follow-up. Enforcement staff may then conduct a site visit or issue a notice based on meter data alone.

Is my drip irrigation system exempt from the Stage 1 schedule?

Drip irrigation is exempt from the two-day-per-week schedule and the 10 a.m.–6 p.m. time restriction under Fort Collins Stage 1 rules. Drip systems deliver water directly to root zones with minimal evaporation loss, which is why they receive different treatment under the restriction framework. This exemption covers vegetable gardens, shrub beds, and trees irrigated via drip emitters. Standard spray-head or rotor sprinkler systems are not exempt and must follow the assigned-day schedule.

What rebates does Fort Collins Utilities offer for replacing grass with drought-tolerant landscaping?

Fort Collins Utilities runs the Water Efficiency Program, which includes turf replacement rebates for homeowners who convert traditional Kentucky Bluegrass lawn areas to water-wise landscaping. Rebate amounts and eligible plant lists are published on the Fort Collins Utilities website at fcgov.com/utilities under the Water Conservation section. The city also offers a Xeriscape Incentive Program (ZIP) that provides financial incentives for converting irrigated turf to low-water-use native and adaptive plants. Contact Fort Collins Utilities directly to confirm current rebate rates and application requirements, as funding availability can change seasonally.

Can I wash my car at home during Stage 1 restrictions?

Yes, but only on your two assigned watering days, and only using a hose equipped with an automatic shut-off nozzle. Letting water run continuously from an open hose is not permitted. If your assigned days don't align with when you need to wash your vehicle, commercial car washes that use recirculating water systems are permitted without day-of-week restrictions under the current Stage 1 rules and are also significantly more water-efficient than home washing.

My neighbor is watering every day — who do I report this to?

Report suspected violations directly to Fort Collins Utilities through the online customer service portal at fcgov.com/utilities or by visiting the utility's offices. When submitting a report, note the address, the date and time you observed irrigation running, and whether the system appeared to be a sprinkler or drip setup. Fort Collins Utilities logs all complaints and investigates based on priority and staff availability. The city's smart meter data can corroborate complaint reports, which speeds up the verification process for flagged addresses.

Will Stage 1 restrictions damage my established Kentucky Bluegrass lawn permanently?

Established Kentucky Bluegrass will typically go dormant rather than die under a two-day-per-week watering schedule during peak summer heat on the Front Range. Dormancy — the browning and apparent die-off of the above-ground blades — is a survival mechanism, not permanent death. The crown and root system generally survive if the lawn receives some water at least every 10 to 14 days, which two assigned days per week satisfies. Once restrictions are lifted and normal irrigation resumes, or when fall temperatures drop and precipitation returns, bluegrass typically recovers and greens up within two to three weeks.

What days can I water my lawn in Fort Collins?

2 assigned days/week Hand watering with a shut-off nozzle is typically allowed any day during permitted hours.

What time can I water in Fort Collins?

Watering is allowed Not 10am-6pm. Watering outside these hours is a violation even on your assigned day.

What are the fines for watering violations in Fort Collins?

First offense: Warning first. Repeat violations: Fines. Contact Fort Collins Utilities for the full enforcement schedule.

When will water restrictions end in Fort Collins?

Current Stage 1 Mandatory restrictions are in effect through Until conditions improve. Monitor https://www.fcgov.com/utilities for the latest status.

Can I hand water during Fort Collins 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 Fort Collins Utilities.
