Tucson official says city can fight water cuts despite data

TUCSON, Ariz. (AP) — Tucson’s top water official has said that the city could withstand a “worst plausible scenario” cut of 50% of its total Colorado River allocation from the Central Arizona Project canal system.

Interim Assistant City Manager Tim Thomure said much of the water that could be cut is not currently under customer use and that the city stores more than one-third of its CAP supply in large basins for emergency use, the Arizona Daily Star reported Saturday.


The assurance came despite warnings from researchers who have warned that the Colorado River Basin could face severe cuts in water supplies due to climate change and other factors.

The data shows that climate change might interfere with the city’s future supply of water, including the natural recharge of its aquifer due to reduced rainfall and increased evaporation, the newspaper reported.

A new federal study warns that continued climate change could reduce natural recharge, said Kathy Jacobs, a University of Arizona climate scientist.
