Why Washington Park Waters on Different Rules Than Your Wash Park Yard This Fall

"There really was nothing in the area but scrub where Washington Park is today," Washington Park community member Sarah McCarthy told Denver Water in 2017, at the 150th anniversary of City Ditch. "The ditch brought water for farms and homes and helped transform City and Washington parks into the urban gardens they are today."

That ditch is why the park and your front yard follow different rules this fall. Since October 1, 2026, a typical Denver Water home customer can't water grass at all, not even by hand. The park's turf runs on a separate recycled-water supply that the drought rules handle under their own clause, and that clause holds only as long as reusable return flows keep reaching Denver Water's Recycling Plant. For the yard on your side of the street, the ban moves the work from the lawn to the trees.

The ditch that got here before the neighborhood

City Ditch started flowing in 1867. The Capitol Hydraulic Company had the idea, and engineer Richard Little, the man Littleton is named for, laid out a route that drew from the South Platte farther upriver. Denver took control of the ditch in 1875, and Denver Water bought it in 1918.

Most of it has been in pipes since about 1898, but you have probably walked past the part that hasn't. Denver Water's open stretch still runs through Washington Park, and today its main job is irrigating the park and filling the lakes in Washington and City parks. Since 2004, the northern section has carried water from Denver Water's Recycling Plant, and stormwater flows through it too. Washington Park and the open section of the ditch went on the National Register of Historic Places in 1976 and were named a Denver Landmark in 1977.

The Recycling Plant sits in Commerce City, next to Metro Water Recovery's Robert W. Hite facility. According to Denver Water's recycled water program, Washington Park is one of the users that gets recycled water through a ditch system. Ditch delivery is classified differently from the usual piped service, so you won't see purple pipe markings the way you would at other recycled-water sites.

That recycled supply decides how the park is treated under the 2026 drought rules.

Why the park's grass falls under a different clause

Denver Parks and Recreation's drought response page says about 30% of its properties are irrigated with recycled water. Washington Park is on that list, along with Cheesman Park, City Park, Congress Park, Harvard Gulch Park and Sloan's Lake Park. The city says these properties keep irrigating "as normal" under Denver Water's annual watering rules, and they still can't water between 10 a.m. and 6 p.m.

The Board of Water Commissioners' resolution behind the October ban, Resolution #002a-2026, is more careful about it. It says the Board is not reducing recycled water deliveries "at this time to the extent that reusable return flows are available" at the Recycle Plant. If the recycled system is ever left with only water from storage, recycled-water licensees have to adopt the same restrictions as everyone else, or stricter ones if the Board sets them.

Here is how the rules divide after October 1, according to the resolution and the city's drought page:

The park also lives with some 2026 cutbacks. Decorative fountains across the city system are off for the whole 2026 season. The city expected most flower beds to be planted this year, and most of them sit on grass irrigation zones and get watered like grass. Earlier in the year, the city said that if the drought held, brown patches would likely show up depending on park use, how old the irrigation system is and where the water comes from.

What the ban leaves you on your own block

The ban takes your lawn out of the picture and leaves the trees, and Denver puts the care of a street tree on the owner of the adjoining property. The city's General Tree Care page assigns that responsibility, and the parks department encourages residents to keep watering the right-of-way trees in front of their homes. The city notes that trees can take years to show stress from too little water.

The Office of the City Forester's trees and drought guidance recommends slow, deep watering at about 10 gallons per inch of trunk diameter, with mulch, repeated every few weeks when there's no snow, until real spring precipitation arrives. City Forester Luke Killoran told Denver Water to water at the dripline, to watch for yellowing or curling leaves and early leaf drop, and to water young trees more often than mature ones. CSU Extension's winter guidance adds a temperature rule: water only when it's above 40°F and the ground isn't frozen, after roughly three to four weeks without measurable moisture.

The same resolution reaches into a few everyday routines that have nothing to do with lawns:

• Washing the car at home. Use a bucket or a hand-held hose with an automatic shutoff nozzle.
• Power washing a patio or walk. Individuals can't power wash unless there's an immediate health or safety reason.
• Annuals and vegetable beds. Hand hose or drip is allowed any day until the first frost after September 30.
• Your irrigation controller. All controllers have to be reprogrammed to comply. A system can run for repair or maintenance only while someone is attending it.
• Dinner on South Gaylord or Old South Pearl. Restaurants and caterers serve water only on request.

If a lawn service handles your yard, the city of Cherry Hills Village's notice on the ban asked residents to pass the rules along to their landscapers. The same advice works here.

How the ban is being enforced

Since October 1, fines for single-family customers start at $500 and rise to $1,000. Multifamily, commercial and municipal accounts start at $1,000, and repeat violations can lead to service suspension. That's according to Denver Water's September 28 enforcement notice. Denver Water's Greg Fisher told Denver7 that enforcement relies on photos submitted by neighbors and on observations from field staff.

The early numbers show the ban working. Denverite reported that customer use from October 1 to 12 ran 34% below the five-year average. In under two weeks the utility took 840 water-waste reports and issued nearly 300 violations totaling $175,500, mostly to residential properties.

Why the conditional clause matters into spring

The reservoirs explain why the Board took the extra step. Its August resolution found that April-through-July streamflow in the collection system was 95,000 acre-feet, 22% of normal and the lowest in 110 years of records. Storage stood at 73% on August 20, against a historic median of 94%. By Denver Water's October 12 report, total storage had dropped to 67% against a 90% average for that date. Dillon was at 62% against 94%, and Cheesman was at 64% against 82%. As of mid-September, Denver Water expected Cheesman to sit at about 60% or lower by April 1, 2027.

That outlook is why the grass ban has no end date. Denver Water's October 12 update says sprinklers stay off into spring 2027 until the Board decides how and when lawn watering can resume. The temporary drought pricing runs on the same timeline. Residential Tier 1 use is exempt, Tier 2 pays an extra $1.10 per 1,000 gallons and Tier 3 an extra $2.20. The surcharge started with May water use and is set to last through April 30, 2027, unless the Board changes it.

The park's grass keeps its exemption only while reusable return flows reach the Recycling Plant, and a home lawn stays dry until the Board votes otherwise. Until then, a hand-held hose with a shutoff nozzle on a tree is allowed any day of the week.

There are a couple of programs for residents thinking past this winter. Denver Water's 2026 turf-removal discount through Resource Central, up to $750, has used up its allocation and closed to new applications. Garden In A Box offered a limited number of $25 discounts on water-wise plant kits. Denver Water estimates each garden saves at least 7,000 gallons over its lifetime compared with the same patch of Kentucky bluegrass. The Park People's Denver Digs Trees gave out about 1,000 free or low-cost trees in April 2026 and teaches tree watering to Denver residents, including renters and HOAs.

If a brown lawn and a street tree to keep alive have you planning next year's yard, or wondering how buyers will see a front yard that went through a drought winter, Makin' Moves with Georgia is glad to talk it through over coffee near the park.
