Arizona Accepts 760,000 Acre-Foot Colorado River Cuts for 2 Years Despite Legal Objections

3 articles · Updated · The Arizona Republic · Aug 25

Summary

  • Arizona water officials said they can absorb federal Colorado River cuts of 760,000 acre-feet a year for two years, even as they called the plan legally flawed and reserved the right to sue.
  • The state backs the short-term cap because it avoids a harsher scenario in which Lower Basin cuts could rise to 3 million acre-feet, a level Central Arizona Project officials warn could dry the canal serving Phoenix and Tucson.
  • CAP and city officials said the two-year reprieve must be used to secure legislative approval before October and build alternatives, including groundwater recovery systems, new pipes, treatment plants and possible desalination or California exchange deals.
  • Phoenix officials warned the Lower Basin-only approach could leave Washington responsible for billions of dollars in adaptation costs, while Arizona also wants more water released or counted from Upper Basin reservoirs after the two-year period.
  • Nevada's lawsuit against the federal plan sharpened pressure on Arizona's review, but state officials said their immediate priority is locking in the two-year deal and voluntary conservation to keep Lake Mead from falling further.
