CLAIM UNDER REVIEW
Arizona’s approximately 27% statewide calculation does not establish an across-the-board 27% cut to Yuma.
Arizona’s approximately 27% statewide calculation does not establish an across-the-board 27% cut to Yuma.
Assessment
The evidence supports the main point, with stated limitations.
This is an editorial assessment of the cited evidence, not a finding by a court or public authority.
Evidence summary
Editorial inference: 760,000 divided by the listed 2,800,000-acre-foot basic apportionment is about 27.14%. Different local priority classes and the preliminary on-river Priority 4 TBD prevent that arithmetic from establishing a uniform user allocation.
What the evidence establishes
Editorial inference: 760,000 divided by the listed 2,800,000-acre-foot basic apportionment is about 27.14%. Different local priority classes and the preliminary on-river Priority 4 TBD prevent that arithmetic from establishing a uniform user allocation.
What it does not establish
That Yuma is exempt, loses nothing, or has any particular final percentage reduction. This is not a judicial holding.
What remains unknown
Final user-specific 2027 delivery treatment.
