Tucson Field Office Flood-Warning Gages
The Tucson Field Office installed these flood-warning gages in cooperation with Pima County Flood Control and Arizona Division of Emergency Management to provide flood warning to population downstream. The recently burned areas in the Catalinas have produced floods two to five times larger than usual. We expect the burned areas to produce similar floods this monsoon season.
