Allowed Watering Hours
The City of Cortez Water Department has mandatory restrictions in effect since May 15, 2026 prohibiting lawn watering between 10:00 a.m. and 5:00 p.m. Voluntary conservation was already in effect city-wide before that date. There is no mandatory address-day schedule; the rule is the midday watering ban. Cortez municipal water supply is secure and is not facing cuts, but the city moved to mandatory midday restrictions because of the severe Dolores River basin drought. Hand watering, drip irrigation, and watering outside the midday window remain permitted.

Fines & Enforcement
Enforced under the City of Cortez Water Department mandatory restriction ordinance
Mandatory midday watering restrictions are enforced by the City of Cortez Water Department. Verify current enforcement and penalty details with the city; the restriction took effect May 15, 2026.
Citations begin May 15, 2026 (mandatory); voluntary conservation already in effect city-wide🏠 HOA Rules During Restrictions
Colorado law (HB 24-1030 and earlier statutes) limits HOA authority to require turf irrigation that conflicts with municipal water restrictions or to penalise residents for drought-compliant landscaping. HOAs cannot fine Cortez residents for following the mandatory midday watering ban.
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 City of Cortez Water Department's current restriction order. 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
Cortez (population ~9,000) is the Montezuma County seat in the Four Corners region of southwest Colorado, roughly 6,200 feet in elevation in high-desert sagebrush country. The City of Cortez Water Department draws primarily from the Dolores Project (McPhee Reservoir, delivered by pipeline) plus city wells.
Southwest Colorado is in severe, multi-year drought. San Juan Mountains snowpack measured roughly 5 per cent of average by April 1, 2026, and snow melted about a month earlier than usual. The Dolores River, which feeds McPhee Reservoir, has been running near 23 per cent of average flow, and McPhee storage is projected to be very low through the summer. The Colorado Drought Task Force escalated its response in May 2026 amid record-breaking conditions.
The drought's hardest impact in the Cortez area falls on agriculture: farmers and ranchers receiving McPhee Reservoir water have been allocated roughly 13 per cent of a normal supply, with senior water-rights holders at about 40 to 50 per cent. Municipal water for the City of Cortez is not facing cuts, but the city adopted a mandatory midday watering ban (no lawn watering 10 a.m. to 5 p.m.) in effect since May 15, 2026, on top of the voluntary conservation already requested city-wide.
Cortez is the gateway city to Mesa Verde National Park, about 10 miles east on US 160, and sits within the Ute Mountain Ute Tribe's regional homeland; the Ute Mountain Ute Reservation manages its own water under separate tribal jurisdiction. Cortez draws from the Dolores Project, a different system from nearby Mancos (about 17 miles east), which uses Jackson Gulch Reservoir on the Mancos River. Same county, different watersheds and different utilities. Southwest Colorado's snowpack comes from the San Juan Mountains and is independent of the Colorado Rockies snowpack that feeds Denver and the Front Range, which is why SW Colorado can be in severe drought while the Front Range is comparatively wetter.
This deficit has accumulated over the current water year and represents a significant departure from historical averages for the Cortez area. Water supply reservoirs and aquifer levels are well below seasonal targets, necessitating mandatory conservation measures.
How to Keep Your Lawn Alive During Cortez Water Restrictions
10 tips tailored for Cortez homeowners during Mandatory Midday Watering Ban - In Effect Since May 15, 2026 restrictions.
Mandatory rule since May 15, 2026: no lawn watering between 10 a.m. and 5 p.m. Water early morning or evening only.
Cortez sits at ~6,200 feet in high desert. Kentucky Bluegrass lawns need deep, infrequent watering; allow summer dormancy rather than fighting the drought.
Hand watering with a shut-off nozzle and drip irrigation are permitted; prioritise trees and shrubs, which are costly to replace.
Install a rain barrel: Colorado law allows residential rain barrels (up to two, 110 gallons total) and captured rainwater is unrestricted.
Convert turf to xeriscape with Four Corners natives (rabbitbrush, blue grama, penstemon). Xeriscape handles the high-desert climate and the midday ban with ease.
Mow at the highest setting and leave clippings to shade the soil in the intense SW Colorado sun.
If you are visiting Mesa Verde National Park, the NPS visitor center can advise on campground water rules, which may be stricter than city rules.
Private wells outside Cortez city limits in Montezuma County are generally not subject to city restrictions; verify with the county.
Skip fertiliser through summer. It forces growth that demands water the drought cannot support.
Monitor cortezco.gov for any escalation. McPhee Reservoir conditions are reviewed through the Dolores Water Conservancy District.
