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.

In a rapidly growing desert metropolis such as Phoenix, the question of which water conservation measures and factors actually save water and which do not is an obviously important one. The water-related decisions made today and in the years to come will have lasting impact on the future of this area, including upon its sustainability. Estimates from the City of Phoenix suggest that, in non-SRP-areas, water demand will exceed water supply by the year 2025--absent droughts or intervention.

This report documents and analyzes the results of a multivariate regression analysis designed to estimate the effects on residential, single-family water consumption of a host of factors, particularly water conservation policies.
