Frederick CO Water Restrictions 2026

Current water restrictions in Frederick, Colorado

Frederick declared Stage 1 Mandatory Water Restrictions in spring 2026 alongside neighboring Firestone, in response to Colorado's lowest-snowpack winter on record. Outdoor irrigation is limited to two days per week by address parity, with a midday blackout from 10 a.m. to 6 p.m.

Frederick is the second of the three Carbon Valley communities — alongside Firestone to the south and Dacono to the north — in the rapidly developing southern Weld County corridor. The town's population has grown rapidly since the 2010s, but Frederick has a longer industrial history than its neighbors. The town was founded as a coal mining community: the name comes from a coal mine established in 1907, and Frederick's 20th-century identity was shaped by the underground mining industry that supplied coal to the Front Range and beyond.

That mining legacy still affects the town today. Some areas have subsidence concerns — gradual ground settling from the collapse of old underground mine workings — that complicate water and sewer infrastructure planning. Mapping the historical mine workings, monitoring surface deformation, and routing new pipelines around subsidence-prone ground are all part of how Frederick Utilities operates. None of this is new in 2026, but it's a permanent feature of the town's water-infrastructure landscape that distinguishes Frederick from its neighbors.

Frederick's service area also has an unusual dual-provider arrangement. The town operates Frederick Utilities for most service areas, but portions of the town are served by the Left Hand Water District — a regional water cooperative serving parts of southern Boulder and Weld counties. Whether your home is served by Frederick Utilities or Left Hand depends on the specific subdivision and historical service-area boundaries. Both providers are administering Stage 1 mandatory restrictions, but rates, billing, and customer-service contacts differ.

Your assigned watering schedule

Hand watering with a hose and shut-off nozzle is permitted on any day, outside the daytime blackout. Drip irrigation for trees and non-turf plantings is exempt from the day-of-week schedule.

• New sod and seed: 21-day establishment variance available — register with your provider (Frederick Utilities or Left Hand Water District) before installation.
• Vegetable gardens: drip and hand watering allowed any day. Sprinkler-based vegetable gardens are scheduled.
• Reclaimed water: some commercial properties and parks operate on reclaimed-water schedules.
• Vehicle washing: permitted with a hand-held hose with shut-off nozzle, outside the daytime blackout.

Fines and penalties

Frederick enforces Stage 1 through Code Enforcement and the relevant water provider with a progressive penalty structure under the town's drought ordinance:

• First violation: a written warning, logged against the customer account.
• Second and subsequent violations: escalating civil fines under the town's drought ordinance.
• Persistent or willful violators: the relevant provider can pursue service-restriction action.

Customers served by Left Hand Water District should report violations to Left Hand directly; customers served by Frederick Utilities should report to the town. Either provider will route reports appropriately. To report a violation, call 720-382-5500 (Frederick Utilities) or use the relevant provider's online reporting form.

Other outdoor water rules

• Watering during measurable rain: prohibited. Functioning rain sensors required on automatic systems under Colorado law.
• Excessive runoff: water sheeting onto streets, sidewalks, or storm drains is a violation regardless of day or hour.
• Pressure washing: permitted only for surface preparation prior to paint, sealant, or repair, or where required for health and safety.
• Decorative fountains: must recirculate water.
• Pool filling: top-offs permitted; new fills require coordination with the relevant provider.

Frederick's water supply and source

Frederick's water portfolio is split between two providers and three sources:

• Frederick Utilities serves most of the town. Sources include:
  • Colorado-Big Thompson (C-BT) project via Northern Water — Western Slope water through the Adams Tunnel.
  • Local groundwater wells in the Carbon Valley alluvial aquifer.
• Left Hand Water District serves the remaining service areas of Frederick. Sources include the St. Vrain Creek and Left Hand Creek watersheds plus C-BT allocations.

The dual-provider arrangement reflects the town's historical growth — Left Hand's service-area boundaries were set decades ago based on which subdivisions were within practical reach of Left Hand's distribution mains, and as Frederick has grown, some new areas joined Left Hand and others were absorbed into Frederick Utilities. The arrangement creates some operational complexity (different rate structures, different rebate programs) but is stable and well-documented.

The Carbon Valley aquifer beneath Frederick has been declining measurably since the 2010s, similar to the conditions affecting Firestone. Mining-related groundwater issues add another layer of complexity here: historical mine workings can intercept groundwater, and pumping patterns near old mine boundaries require careful management.

Mining subsidence does not directly affect water quality in Frederick's wells, but it does shape where and how new wells can be drilled and how distribution mains are routed. Mining-era maps held by the Colorado Division of Reclamation, Mining and Safety, and by the town itself, are referenced any time new infrastructure is planned.

HOA rules during water restrictions

Colorado Revised Statutes § 37-60-126 protects homeowners from HOA enforcement actions for compliance with declared water-conservation measures. The statute applies in every Frederick master-planned community.

Sample HOA response:

"Dear [HOA Architectural Review Committee], the Town of Frederick has declared Stage 1 Mandatory Water Restrictions limiting outdoor irrigation to two days per week. My lawn reflects compliance with that declaration. Under Colorado Revised Statutes § 37-60-126, the Association may not enforce covenants requiring irrigation inconsistent with the water provider's conservation measures. Please withdraw the violation. Sincerely, [Your name]"

Lawn survival guide for Frederick

Frederick lies in USDA Hardiness Zone 5a/5b. Common turf and landscape options:

Mow on the high end. Bluegrass mowed at 3.5–4 inches retains moisture better than at 2 inches.

Skip summer fertilizer. Fertilizer pushes growth the limited irrigation cannot support.

Mulch beds heavily. Two to three inches of bark mulch dramatically reduces evaporation in shrub beds.

Brown is not dead. Bluegrass goes dormant under heat-and-drought stress and recovers reliably.

Consider buffalograss for new yards. Carbon Valley's combination of declining groundwater and snowpack risk makes buffalograss a practical long-term choice.

Frequently asked questions

Am I served by Frederick or Left Hand Water District?

Some areas of Frederick are served by Left Hand Water District rather than Frederick Utilities. The split is based on historical service-area boundaries and varies by subdivision. To find out which provider serves your home, check your water bill (which lists the provider) or call Frederick Utilities at 720-382-5500. Both providers are administering Stage 1 mandatory restrictions during the 2026 drought, but rates, billing, and customer-service contacts differ.

Why was Frederick founded as a coal mining town?

Frederick is named after the coal mine established in 1907. The town's 20th-century identity was shaped by the underground coal-mining industry that supplied fuel to the Front Range. Modern Frederick is residential and the active mining era ended decades ago, but the historical workings remain underground and continue to shape some areas through subsidence and infrastructure-planning constraints.

Does mining subsidence affect water quality?

No. Mining subsidence is a structural concern — gradual ground settling above old mine workings — not a water-quality concern. Frederick's wells are sited and operated to comply with state and federal drinking water standards, and the town's water meets those standards. Subsidence does affect where new infrastructure can be built and how distribution mains are routed, but it does not affect the quality of water flowing through the taps.

What days can I water in Frederick?

Even addresses water Tuesday and Saturday. Odd addresses water Wednesday and Sunday. No watering between 10 a.m. and 6 p.m.

What if I just installed new sod?

Register with your water provider (Frederick Utilities or Left Hand Water District) for a 21-day establishment variance before installation. The variance allows more frequent watering during establishment. After 21 days, the standard schedule applies.

How is Frederick handling Carbon Valley aquifer decline?

Like neighboring Firestone, Frederick supplements groundwater pumping with C-BT surface-water deliveries to manage aquifer drawdown. Long-term planning across the three Carbon Valley towns (Frederick, Firestone, Dacono) is increasingly focused on demand reduction through conservation and on continued surface-water investment to reduce groundwater dependence.

How long will Stage 1 last?

Through at least the 2026 irrigation season. Both Frederick Utilities and Left Hand Water District review status as C-BT allocations and reservoir conditions evolve.

What time can I water in Frederick?

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 Frederick?

First offense: Written warning. Repeat violations: Escalating fines. Contact Town of Frederick Utilities for the full enforcement schedule.

When will water restrictions end in Frederick?
