Kennewick Irrigation District customers can no longer use hoses to spot water areas of lawn that are turning brown, the district announced Wednesday.
The amount of Yakima River water available to the district has dropped, causing the end to spot watering of lawns.
Frequent changes to watering rules likely will continue through the drought, the district said. The district knows only about a day in advance how much water it will be able to divert from the Yakima River, the river for which it holds water rights.
Residential customers may continue to water each zone of their lawn for up to 30 minutes on a preset schedule twice a week. They also may use a single hose or high efficiency devices to water trees, shrubs, perennials and vegetable gardens.
KID also will be contacting agriculture and other large water users about revisions to their water schedule.
