It is in the public interest to provide a plan of action by the city and its water customers, to respond to water supply shortage events, including, but not limited to, Skagit River levels that are below the minimum instream flow levels established by the Department of Ecology. In the case of low river levels, the goal is to reduce the possible impact the city’s diversions may have on the recommended instream flows for the lower Skagit River. To accomplish this declared purpose, the city reserves the right to exercise its police powers through emergency measures as set forth in this chapter. (Ord. 2797 § 1, 2009)
