Meetings & Workshops

2006 - 2007 - 2008 - 2009

Date: September 6, 2006
Location: Decision Center for a Desert City, Tempe, AZ

From 12 Noon until 1:30 PM this workshop combined EWSR with the DCDC Water Briefing. Our project team made a brief summary presentation on our findings, and Bob Balling and Drew Ellis of ASU made a climate-related presentation.

EWSR Meeting Agenda

Summary:

This workshop included presentations and discussions between water managers and users in Arizona and a team of researchers from the University of Arizona. We have been working for the past two years on ways to incorporate climate information into the management of the Lower Colorado River Basin. This study builds from questions provided to us by water management stakeholders in the fall of 2004, including ADWR, CAP, SRP, AMWUA, and SAWUA as well as Reclamation. In addition to presentations and results, the workshop provided a forum for input to define the next phase of research to meet the needs of water managers and Reclamation (this study is being expanded to a second two-year period). The project is focused on ensuring that research results can be transferred to the context of shortage planning and the mitigation of water supply impacts associated with climatic variability and drought. Phase 2 of the project is in partnership with Arizona State University in the context of the Arizona Water Institute.

Presentations:

1. Introduction (Jacobs)
2. Predictive Capacity
   • Updated streamflow reconstructions for the Upper Colorado River Basin (Meko and St. George)
   • Climate-based streamflow forecasting in Riverware: The Ensemble Streamflow Prediction Method in RiverWare (Nijssen and Lindenmayer)
3. Decision Support
   • Economic Arrangements to Enhance Dry Year Supply Reliability in the Lower Colorado River Basin (Colby and Pittenger)
   • Decision Making under Uncertainty: Shortage, Stakeholders, and Modeling in the Lower Colorado River Basin (Jacobs and Garrick)

Information on EWSR workshops in 2007 will be added here soon.

Information on EWSR workshops in 2008 will be added here soon.

Date: September 2-3, 2009
Location: Sabino Room, University of Arizona Student Union, Tucson, AZ
