Back to Stage 2 Drought

By Amy Smith, August 30, 2012, 2:02pm, Newsdesk

With lake levels dropping by the day, Austin Water will re-activate Stage 2 water restrictions starting Tuesday, Sept. 4. The utility expects the city's combined water storage levels of Lakes Travis and Buchanan to fall below the trigger of 900,000 acre-feet within the next week.

Under Stage 2, city utility customers are limited to once-weekly outdoor watering schedules.

From Austin Water's press release: "Stage 1 restrictions have been in effect for the past six weeks. The brief return to a two-day per week watering schedule provided relief for customers concerned about trees and other landscaping investments through the hottest part of the summer. The time was also used by the city to update its water management strategy. The improved strategy allows for a more efficient overall response to water use during our area's current drought conditions."
