City of Bozeman Bozeman residents can track water usage with the Drought Water Use Gauge on the drought management section of the city's webpage. As of last Friday Bozeman residents can only water their lawns at certain times of the day and week. The restrictions are intended to preserve city water supplies as drought conditions worsen. Bozeman’s drought plan kicks off when there’s not enough water flowing in nearby streams and reservoirs. The stage two restrictions that were adopted last week limit outdoor lawn watering to two days per week. There are also water rate increases. The reason that we target lawns in our drought plan as the first thing to go so to speak is they are resilient,” explains Jessica Ahlstrom, Bozeman’s Water Conservation Program Manager. “If your lawn goes dormant now, the vast majority of the time it will come back next spring.”
