Summary
Columbia, Missouri has no standing lawn-watering schedule: irrigation restrictions kick in only when the city manager declares a water use emergency, triggered by a main break or demand nearing 24 million gallons a day.
(a) The city manager is authorized to declare a water use emergency under any of the following conditions: (1) An equipment failure, large fire or water main break has caused or, unless emergency water conservation measures are taken, will cause inadequate water pressures and flows for fire protection. (2) Water system pumping is reasonably estimated to reach the 24 million gallons per day level. (b) After declaring a water use emergency, the city manager shall establish temporary emergency regulations.

Full Breakdown
Columbia's code carries no year-round odd/even watering-day ordinance. Instead, Code of Ordinances § 7-5 lets the city manager declare a 'water use emergency' when an equipment failure, large fire, or water main break threatens fire-flow pressure, or when citywide pumping is reasonably estimated to reach 24 million gallons per day. Once declared, the city manager issues temporary emergency regulations, which can include irrigation cutbacks, under the same notice, 21-day expiration and penalty procedures set out in § 7-4 for general emergency regulations. The authority applies citywide within Columbia, Boone County, Missouri.
Violations & Fines
Violating a temporary emergency water regulation after notice is an offense punishable by up to $1,000 or three months in jail under § 7-4(b); lesser breaches are infractions capped at $200.
