San Francisco Bay/Sacramento-San Joaquin Delta Estuary (Bay-Delta) Program

Draft Substitute Environmental Document in Support of Potential Changes to the Water Quality Control Plan for the Bay-Delta: san joaquin river flows and southern delta water quality

On December 31, 2012, the State Water Board released for public review and comment a draft Substitute Environmental Document (SED) in support of potential changes to San Joaquin River flow and southern Delta water quality objectives and program of implementation included in the Water Quality Control Plan for the San Francisco Bay/Sacramento-San Joaquin Delta Estuary (Bay-Delta Plan). The public notice and SED chapters and appendices are posted below.

Proposed changes to the Bay-Delta Plan include:

  1. New narrative February through June Lower San Joaquin River (LSJR) flow objective applicable to the salmon bearing tributaries to the LSJR (the LSJR, Merced, Tuolumne, and Stanislaus rivers) and an associated program of implementation to support and maintain the natural production of viable native LSJR watershed fish populations migrating through the Delta; and
  2. Revised numeric southern Delta salinity objectives and an associated program of implementation to protect agricultural beneficial uses in the southern Delta.

The SED and associated appendices were prepared in compliance with the California Environmental Quality Act, the California Water Code and other applicable State and federal requirements and include an analysis of the expected environmental, water supply, economic, and hydropower effects of the LSJR flow and southern Delta salinity alternatives. Written comments on the draft SED were due by noon on Friday, March 29, 2013. A hearing for receipt of oral comments was held March 20-21, 2013. See the Notice of Filing and of Public Comment Period and Hearing on the Adequacy of the Draft Substitute Environmental Document for further details.

On September 15, 2016, the State Water Board released for public review and comment a Draft Revised SED.
