Drought is endemic to Arizona. The climate of the state is not merely arid, but characterized by multi-decade episodes of drought, punctuated by high interannual precipitation variability. The 2004 Arizona Drought Preparedness Plan (ADPP) mitigates drought impacts through continuous drought monitoring, a statewide drought and water conservation program, and an engaged public. For over one year, climatologists have worked with statewide drought plan coordinators to implement an innovative recommendation in the ADPP – a volunteer network of drought impacts reporting, and county-level mitigation and response planning coordinated with the ADPP. Multiple agencies, universities, and private sector partners, in conjunction with the Arizona Department of Water Resources, are developing a web-based hydroclimatic information system that will contribute to the National Integrated Drought Information System. The system coordinates hydroclimatic data for a temporal spectrum that ranges from long-term climate and streamflow data to real-time flood warning. This presentation will address the implementation of these innovations, and present lessons learned about the processes of coordinating between stakeholders, decisionmakers, and state and federal agencies.
