Water restrictions in Mohave County, AZ — also called the watering schedule, outdoor irrigation rules, or drought ordinance — set which days and hours you can run sprinklers or irrigation.
Most of Mohave County sits outside any Active Management Area, so the strict groundwater-conservation and assured-water-supply rules governing Phoenix and Tucson do not apply. Household wells are largely unregulated, but the Hualapai Valley basin is a declared Irrigation Non-Expansion Area.
Arizona's 1980 Groundwater Management Act created Active Management Areas with pumping limits and 100-year assured-water-supply mandates, but Mohave County has no AMA, so those conservation rules do not reach homeowners here. Rural basins including Sacramento Valley, Detrital Valley, and Hualapai Valley rely on private wells; a domestic well pumping 35 gallons per minute or less needs no permit. The exception is Hualapai Valley, designated an Irrigation Non-Expansion Area in December 2022 after years of decline and a roughly 50,000 acre-foot annual deficit, which freezes new irrigated farm acreage but not household use. Colorado River cities like Lake Havasu City and Bullhead City draw treated river water.
No countywide watering schedule or conservation penalty applies to households outside an AMA. Expanding irrigated cropland inside the Hualapai Valley INA is an Arizona Department of Water Resources matter. City utilities set their own conservation rules and surcharges.
