Existing law requires the Department of Water Resources to gather and correlate information and data pertinent to an annual forecast of seasonal water crop. Existing law also requires the department to update every 5 years the plan for the orderly and coordinated control, protection, conservation, development, and use of the water resources of the state, which is known as "The California Water Plan."
This bill would require the department, on or before January 1, 2027, to adopt a new water supply forecasting model and procedures that better address the effects of climate change and implement a formal policy and procedures for documenting the department's operational plans and the department's rationale for its operating procedures, including the department's rationale for water releases from reservoirs. The bill would also require the department to establish, and publish on the department's internet website, the specific criteria that it will employ to determine when its updated water supply forecasting model has demonstrated sufficient predictive capability to be ready for use in each of the watersheds. The bill would require the department, on or before January 1, 2028, and annually thereafter, to prepare and submit to the Legislature a report on its progress toward implementing the new forecasting model and to post the report on the department's internet website. The bill would also require the department, on or before January 1, 2028, and annually thereafter, to prepare and submit to the Legislature a report that explains the rationale for the department's operating procedures specific to the previous water year.
The bill would require the department, commencing in 2027 and annually thereafter, to present specified information, including the department's operational decisions and its rationale for the state's water supply during the preceding water year, at at least 2 open and public meetings in specified locations. The bill would require the department to include the information presented at the meetings in a report, post the report on its internet website, and submit the report to the Legislature.
