PHOENIX — Arizona Gov. Doug Ducey has vetoed the first in a series of water law overhaul bills making their way to his desk, saying a single bill doesn’t address the overhaul of water laws he is seeking.

The Republican governor said in a Thursday veto letter that the proposal doesn’t address Colorado River and groundwater issues.

Bill sponsor Sen. Gail Griffin declined immediate comment but noted the vetoed bill was sought by the governor. It would add exemptions to current pumping rules for greenhouses.

Griffin and Rep. Rusty Bowers introduced the proposals in eight separate bills and one overarching bill. But they did not give the governor his biggest request, major control over Colorado River water now held by the Central Arizona Project’s board.

The vetoed legislation is Senate Bill 1510
