Fort Collins CO Water Restrictions 2026
Published: Updated:
Larimer County· Colorado
Fort Collins has not declared mandatory water restrictions as of April 2026. The city is on Drought Watch status and monitoring the Cache la Poudre watershed closely. Fort Collins Utilities will decide whether to impose mandatory limits in April or May 2026 based on updated snowpack and runoff forecasts. Residents are strongly encouraged to voluntarily limit outdoor watering to no more than 3 days per week and to avoid turning on automatic irrigation systems before May. Fort Collins is NOT a Denver Water customer — it draws from the Poudre River and Horsetooth Reservoir via the Colorado-Big Thompson Project, a separate supply with different triggers than Denver Water’s Stage 1 system.
Current Status
Fort Collins is on Drought Watch — there are no mandatory watering restrictions in place as of April 2026. Fort Collins Utilities recommends voluntary conservation of no more than 3 days per week and strongly advises not turning on automatic sprinkler systems before May. The city monitored conditions throughout March while neighbouring utilities like Denver Water, Aurora, and Thornton declared formal Stage 1 restrictions. A formal decision on mandatory restrictions is expected in April or May based on Poudre watershed runoff projections.
Watering Schedule by Address
No mandatory watering schedule is in effect. Fort Collins Utilities’ voluntary guidance is to limit outdoor watering to no more than 3 days per week, only outside the 10 a.m. – 6 p.m. blackout window. If mandatory restrictions are declared, the framework is expected to mirror Denver Water’s Stage 1 (2 days per week on an address-based even/odd schedule).
| Group | Watering Days |
|---|---|
| Voluntary guidance — all addresses | Maximum 3 days per week |
| If mandatory Stage 1 declared (anticipated) | Even/odd, 2 days per week, 6 p.m. – 10 a.m. |
The 3-day cap and 10 a.m. – 6 p.m. avoidance are advisory in April 2026. Check fcgov.com/utilities weekly for any formal declaration. The standard Colorado rule against watering during or within 48 hours of measurable precipitation applies in practice even under voluntary conservation.
What’s Restricted Beyond Lawn Watering
Under voluntary conservation, Fort Collins Utilities asks residents to avoid washing cars at home unless using a shut-off hose, to postpone pressure washing, and to defer new sod installations until after the April–May decision. Hand watering of trees, shrubs, and vegetable gardens with a can or shut-off-equipped hose is encouraged any time — mature trees and food gardens should be kept alive through any worsening of conditions.
Fines and Enforcement
There are no fines under Drought Watch status — the current guidance is voluntary. If Fort Collins Utilities declares mandatory Stage 1 restrictions in April or May, enforcement is expected to follow the Denver Water model: education-first, with escalating surcharges and citations for repeat violators. Free Slow the Flow sprinkler audits are available through Fort Collins Utilities — booking one now documents your baseline water use if a rebate claim arises later.
HOA Protection in Fort Collins
Colorado law (HB 21-1229) prohibits HOAs from requiring water-intensive landscaping, mandating cool-season turf, or penalizing homeowners for xeriscaping or drought-tolerant landscaping. The statute goes further than most US states by actively protecting homeowners who convert their lawns to drought-tolerant alternatives, even outside of declared drought periods. Combined with the City of Denver's public statement that brown lawns are expected during active restrictions, any HOA fine threatened against a brown lawn caused by following local restrictions is on weak legal ground. Keep a copy of your utility's restriction notice and the relevant city ordinance to share with your HOA board if a violation notice arrives.
Lawn Survival Guide for Fort Collins
Fort Collins sits at ~5,000 ft on the Front Range where Kentucky Bluegrass and Tall Fescue are the dominant lawns. Both tolerate seasonal dormancy — brown KBG under drought conditions is not dead, and a tug test will confirm the crown is still alive.
- Don’t turn on your automatic sprinkler system until May — April irrigation in Colorado’s climate mostly waters dormant grass.
- When you do water, limit to 3 days per week maximum, watering before 10 a.m. or after 6 p.m. only.
- Water deeply (½ inch per session) rather than shallowly and frequently — this builds the deeper root system that survives mandatory restrictions later.
- Check fcgov.com/utilities or sign up for Fort Collins Utilities email alerts to know immediately if mandatory restrictions are declared.
- Fort Collins Utilities offers free Slow the Flow sprinkler audits — book one now while slots are available before demand spikes.
- Mow at 3–3.5 inches to shade the soil — taller cool-season grass loses significantly less moisture between irrigations.
- Tall Fescue overseeded in fall will gradually replace KBG in your lawn — the best way to cut long-term water use without a full conversion.
Will Restrictions Get Worse?
Fort Collins Utilities has indicated a decision on mandatory restrictions will come in April or May 2026 based on Poudre watershed runoff. If projections come in significantly below average, expect a Stage 1 framework similar to Denver Water: 2 days per week, even/odd scheduling, 10 a.m. – 6 p.m. blackout, and drought surcharges for high users. The Colorado HB 21-1229 HOA protection applies immediately upon any formal declaration. Residents who start conserving now will already be ahead of any formal order.
