AZ HCR2046

Designates forest mismanagement and salt cedar proliferation as principal causes of Colorado River water depletion, with the U.S. Bureau of Reclamation estimating nearly 4 million acre-feet of water lost annually to evapotranspiration compared to Arizona's 2.8 million acre-feet allocation.

Identifies salt cedar (tamarisk) as an invasive species covering nearly 2 million acres of riverbanks, with individual trees consuming over 200 gallons of water daily and dense stands depleting approximately 672 acre-feet of water per acre annually.

Calls on state and federal legislators to acknowledge that forest mismanagement and salt cedar proliferation undermine conservation efforts and to support eradication and forest thinning projects as opportunities to increase Colorado River water availability.

Directs Congress to fund salt cedar eradication and mechanical thinning of overgrown forests in Western watersheds.

Requires Arizona Secretary of State to transmit resolution to the President, Congressional leaders, Department of Interior, U.S. Forest Service, Bureau of Reclamation, and Arizona Congressional delegation.
