On February 7, the California Department of Water Resources released a draft Handbook for Water Budget Development: With or Without Models (Water Budget Handbook), a single-volume, technical reference that systematically presents existing information on various methods and data sources for developing water budgets. The Water Budget Handbook can help in the development of water budgets for any geographic area and time period, and uses modeling and non-modeling approaches. Public comment is now open on the draft document and closes on May 7, 2020. More information about the development of the handbook can be found in the Water Budget Handbook Story Map.

Please join us for an interactive public webinar intended to help water budget developers make better use of the Water Budget Handbook. Please take this short survey on water budget development. DWR will the use the results of the survey to tailor the content for the interactive webinar. Please REGISTER for the webinar to participate.

The agenda will cover discussion and Q&A of resources and techniques available in the Water Budget Handbook relating to the components or aspects of water budget development that are identified as being the most challenging/important in the survey.
