Colorado River; cause of decline
HCR 2046 is a non-binding resolution passed by the Arizona legislature, not a bill with legal effect. It identifies overgrown forests and invasive salt cedar (tamarisk) trees as significant causes of water loss in the Colorado River watershed, citing that salt cedar alone consumes approximately 672 acre-feet of water per acre annually. The resolution calls on state and federal leaders to acknowledge these issues and prioritize funding for salt cedar eradication and forest management to increase water availability. It urges Congress to allocate resources for these efforts, directing Arizona officials to send the resolution to federal authorities.

MINOR
The bill was reformatted from an introduced version to a House engrossed version with minor text adjustments to the 'Whereas' clauses. The substantive policy content remains largely the same, though the final resolution clauses were renumbered and slightly reworded for clarity. No new funding amounts, dates, or eligibility criteria were added.
TECHNICAL
The 'Whereas' clauses were slightly reworded for clarity, such as changing 'historic drought, evapotranspiration and salt cedars' to 'a variety of factors, including historic drought, evapotranspiration and salt cedars' to acknowledge other contributing causes.
The resolution clauses were renumbered from 5 to 6 and reworded to specify that state and federal legislators should be involved in the actions, rather than just the Legislature determining them.
A new clause was added requesting the United States Congress fund eradication efforts and enable mechanical thinning of overgrown forests.
