California Water Commission

The California Water Commission consists of nine members appointed by the Governor and confirmed by the State Senate. Seven members  are chosen for their general expertise related to the control, storage, and beneficial use of water and two are chosen for their knowledge of the environment. The Commission provides a public forum for discussing water issues, advises the Department of Water Resources (DWR), and takes appropriate statutory actions to further the development of policies that support integrated and sustainable water resource management and a healthy environment. Statutory duties include advising the Director of DWR, approving rules and regulations, and monitoring and reporting on the construction and operation of the State Water Project. 

· NEW - Public Comment Period for Revised WSIP Regulations

Proposed revisions to the draft Water Storage Investment Program regulations and related documents are now available for public comment. In order to be considered, public comments must be received by 5:00 p.m. on December 7, 2016.

The proposed revisions, related documents, and information about providing public comments can be found on the Quantification Regulations page.

· NEW - Water Storage Investment Program Public Participation Guide

The Commission has released a Water Storage Investment Program (WSIP) Public Participation Guide to provide information about opportunities and methods for public involvement in the WSIP.

The Public Participation Guide is available here.

· NEW - Updated WSIP Model Products

Recently Commission staff completed a quality assurance review of the Water Storage Investment Program (WSIP) Climate Change and Sea Level Rise Statewide datasets and the CalSim-II and DSM2 model products.  As a result, staff recommended some corrections and revisions to the products published on September 9, 2016 (model runs dated 9-3-16). These corrections and revisions are limited to the climate change modifications to the hydrologic inputs to CalSim-II.

If the regulations governing the WSIP are adopted by the California Water Commission, and an applicant uses the model products, these versions of the models will be required. Staff intends to include these new model products in the upcoming formal comment period required pursuant to the Administrative Procedure Act. The Commission is releasing these new versions in advance of the formal comment period to assist and encourage applicants to begin running the models as early as possible.

Information about these updates and the updated model products can be found here.
