Last verified: October 6, 2026, against Denver Water.
Quick answer: Right now, a Denver lawn cannot be watered. Denver Water has prohibited lawn watering and all spray irrigation beginning Oct. 1, until further action by the Denver Board of Water Commissioners. Trees, shrubs and other plants may still be watered with a hand-held hose with an automatic shutoff nozzle or low-volume irrigation such as drip. When the Board lifts the prohibition, this guide covers how to water deeply on clay-loam soil, how Denver Water’s rules work, and water-wise options.
Once the Board lifts the prohibition, the principle stays the same: water deep and infrequent so roots grow down, and water to the weather rather than a fixed schedule. A few good soakings build deep roots that withstand Denver’s dry heat, while daily light sprinkling keeps roots shallow and weak. Until then, put water where it is still allowed: trees, shrubs, perennials, annuals and vegetables, by hand-held hose with an automatic shutoff nozzle or by drip.
Denver Water’s summer watering rules
Denver Water has prohibited lawn watering and all spray irrigation beginning Oct. 1, until further action by the Denver Board of Water Commissioners, under the Board’s Stage 1 Drought Declaration. Denver Water can assess charges for lawn watering and spray irrigation violations: beginning Oct. 1, a single-family customer is charged $500 for a first violation and $1,000 for a second. Check Denver Water for the current rules before programming your controller.
Evapotranspiration: water to the weather, not a fixed schedule
The smartest Denver lawns are watered by evapotranspiration (ET), the combined rate at which water evaporates from the soil and transpires from the grass. ET is high on hot, dry, windy, sunny Front Range days and low on cool or cloudy ones, so a lawn’s real water need changes constantly. A smart, weather-based controller uses local ET data to water only what the lawn actually lost, which keeps drip zones and, once permitted again, lawn zones on only what they need.
Altitude and UV: why Front Range lawns lose water fast
Denver’s mile-high altitude, thin dry air, and intense ultraviolet sunlight pull moisture out of a lawn faster than at lower elevations. The same lawn that needs an inch a week in a humid climate loses more here to evaporation and transpiration, which is why timing and depth matter so much. Watering in the cool morning, before the sun and wind peak, keeps far more water in the soil than a midday run. It is also why mulched beds and deep roots pay off, both buffer the lawn against the rapid drying that defines the semi-arid Front Range.
How to water deeply on Denver’s clay-loam soil
Deep watering means soaking the soil six to eight inches down so roots grow deep, the foundation of a heat- and drought-tolerant Denver lawn. Much of the Front Range has heavy clay-loam soil that absorbs water slowly, so watering too fast just runs off. Use cycle-and-soak: split each watering into two or three shorter cycles with a pause between, letting the water sink in. Aerating compacted clay-loam in spring or fall also helps water penetrate. Check your depth with a screwdriver a few hours after watering, if it pushes in six inches easily, you watered deep enough.
Xeriscape and low-water options
For a lasting cut in water use, consider xeriscape, the water-wise landscaping approach developed in Denver for exactly this climate. Replacing thirsty bluegrass in tough or low-use areas with drought-adapted plants, native grasses like buffalograss, decorative rock, and drip irrigation can dramatically reduce a Front Range water bill, and Denver Water has offered turf-replacement rebates. You do not have to remove the whole lawn, many homeowners keep a smaller bluegrass area for play and convert the rest.
Denver Water Restrictions Right Now
Denver Water has prohibited lawn watering and all spray irrigation beginning Oct. 1, until further action by the Denver Board of Water Commissioners. Trees, shrubs, perennials, annuals and vegetables may be watered any day using a hand-held hose with an automatic shutoff nozzle or low-volume, non-spray irrigation such as drip. Watering Establishment Permits will not be available after Sept. 30 until further notice.
Denver Water has not published a date for lifting the prohibition. It stays in place until further action by the Denver Board of Water Commissioners, so check denverwater.org for the current status before turning any lawn zone back on.

Why is my Denver lawn brown after winter?
Denver lawns usually brown from winter desiccation and turf mite damage, not disease. In a semi-arid winter, dry south-facing slopes and areas near sidewalks lose moisture for months, and mites feed on the stressed grass. Winter watering during warm, dry spells prevents most damage. Patches still dead by late spring need reseeding.
How many days a week does Denver Water allow lawn watering?
Denver Water’s summer rules allow lawn watering on no more than three days per week, and never between 10 a.m. and 6 p.m. Spreading the allowed days across the week, rather than bunching them, keeps a lawn from swinging between soaked and bone-dry.
