California Water Code (Section 10004.6) lists the minimum information that is required for the Assumptions and Estimates report. The table below highlights the major categories required by the Water Code. In some cases, information required by the Water Code is not currently used in the development of Update 2013 because of limited resources or the lack of information. However, where possible, estimated are included for all items required by the Water Code.

The water code requires the following information categories to be included in the Water Plan: basin hydrology, current and projected water use, groundwater supplies, evapotranspiration rates for major crops, current and projected water supplies provided by water recycling and reuse, current and projected adoption of urban and agricultural water conservation practices, environmental water needs, current and projected land use patters, and current and projected population.
