The Operational Drought Plan, contained herein, is the key component for responding to the current and future drought conditions in Arizona. The Operational Drought Plan recognizes that drought events are natural disasters that touch all sectors of community, region, and state. To facilitate a coordinated response to drought events, the Operational Drought Plan identifies a process for communication and coordination between Arizona state agencies, Federal agencies, tribal governments, state lawmakers, water users, resource managers, and scientists.
The purpose of this report is to present the data gathered to date in the Santa Cruz AMA in support of the management goal and groundwater modeling effort. This report presents groundwater and surface water monitoring data, USGS stream gaging data, effluent data, gravity studies, historical water use and water quality data for three distinctive stream reaches of the Santa Cruz River.
Stream flow disappearance due to groundwater pumping, floodplain development, and habitat loss due to erosion have significantly altered the biologically rich and diverse riparian corridors of eastern Pima County. Today, there are new opportunities to recreate our watercourses as a gathering place for people and wildlife.
