Draft Assumptions and Estimates Report

The Draft Assumptions and Estimates Report (Draft A&E Report) presents key assumptions and estimates, data and data sources, and companion plans which will be considered for the preparation of California Water Plan Update 2018 (Update 2018). The report increases the transparency of the Water Plan process by disclosing the data, tools, methods, and references used to prepare Update 2018. The report also describes the approach the Department of Water Resources (DWR) is taking to improve the analytical tools and data being used to develop Update 2018.

DWR will continue to update the Draft A&E Report content online during the remainder of the Update 2018 development process.
