Water Operations Management Team (WOMT) Decisions and Summaries

The Water Operations Management Team (WOMT) is comprised of representatives from the United States Bureau of Reclamation, California Department of Water Resources, Fish and Wildlife Service, National Marine Fisheries Service, California Department of Fish and Wildlife, and the California State Water Resource Control Board. This management-level team was established to facilitate timely decision-support and decision-making at the appropriate level. The WOMT first met in 1999, and has continued to meet to make management decisions as part of operations of the State Water Project and the Central Valley Project. The WOMT accepts input from many information teams including the Smelt Working Group (SWG), the Delta Operations for Salmonids and Sturgeon (DOSS) group, and Data Assessment Team.  Routinely, it also uses the CALFED Ops Group to communicate with stakeholders about its decisions. Although the goal of WOMT is to achieve consensus on decisions, the participating agencies retain their authorized roles and responsibilities.  Meeting notes from the WOMT can be found by selecting the "WOMT Decisions/Summaries" button below.  Access to the SWG and DOSS meeting notes can be found by selecting the appropriate link below.

Data Assessment Team (DAT) Summaries

The Data Assessment Team (DAT) consists of technical staff members from the Project and fishery agencies as well as stakeholders. The DAT meets frequently during the fall, winter, and spring.  The purpose of the meetings is to coordinate and disseminate information and data among agencies and stakeholders that is related to water project operations, hydrology, and fish surveys in the Delta.  Meeting notes from the DAT can be found by selecting the "DAT Summaries" button below.
