Arizona's water depletions for irrigation remain unchanged from those projected for the 8.16 million-acre-foot level of development. Colorado has planned additional projects at this level of development, which would increase irrigation above the 8.16 million-acre-foot level in 2020 by 69,000 acre-feet, primarily in the Upper Main Stem Subregion. 97 |
