Principles for Agreement on Bay-Delta Standards Between the State of California and the Federal Government

California State Water Resources Control Board (SWRCB) | December 15th, 1994

In order to provide ecosystem protection for the Bay-Delta Estuary, representatives of the State and Federal governments and urban, agricultural and environmental interes

In order to provide ecosystem protection for the Bay-Delta Estuary, representatives of the State and Federal governments and urban, agricultural and environmental interests agree to the implementation of a Bay-Delta protection plan through the California State Water Resources Control Board (SWRCB) consistent with the following principles.These Principles describe changes to the California Urban Water Agency/-Agricultural Water Users (CUWAIAG) proposal as the base case for Bay-Delta protections, which are intended to be in force for three years, at which time they may be revised.

Proposal for a Revised ITL and Expected Take for Adult Delta Smelt

Delta Stewardship Council (Delta Council) | July 29th, 2014

The 2008 USFWS Incidental Take Level (ITL) calculation determines the amount of annual delta smelt salvage allowed to be taken by the State Water Project (SWP) an

The 2008 USFWS Incidental Take Level (ITL) calculation determines the amount of annual delta smelt salvage allowed to be taken by the State Water Project (SWP) and Central Valley Project (CVP) during operating conditions expected under Reasonable and Prudent Alternative (RPA) thresholds. There is an ITL for adult and juvenile delta smelt. Using advances in statistical models, data sources, and overall improved knowledge of entrainment dynamics, we offer a robust approach for calculating a revised ITL and accompanying expected take method under the RPA for the SWP and CVP that remains protective of the species while providing improved flexibility for managing water operations.

Proposal for Calculating Cumulative Salvage Index Values Used For Estimating Take Likely to Occur under the USFWS Old and Middle River Flow RPA for Adult Delta Smelt

Delta Stewardship Council (Delta Council) | September 19th, 2014

The objectives of this paper are to provide a rationale why the United States Fish and Wildlife Service (USFWS) Incidental Take Statement should include more years in its calculation of anticipated incidental take of adult delta smelt under the 2008 Biological Opinion with the Reasonable and Prudent Alternative (RPA) action to avoid jeopardy to the species and adverse modification of critical habitat and provide a statistical method by which this can be achieved.

Pulse Flows Component of the Water Storage Investment Program Groundwater Projects Supplemental Environmental Impact Report

California Department of Water Resources (DWR) | July 30th, 2024

This final supplemental environmental impact report (Final SEIR) has been prepared for the Pulse Flows Component of the Water Storage Investment Program (WSIP) Groundwate

This final supplemental environmental impact report (Final SEIR) has been prepared for the Pulse Flows Component of the Water Storage Investment Program (WSIP) Groundwater Projects (Pulse Flows Component). The Final SEIR is a supplement to three certified environmental impact reports (EIRs) prepared pursuant to the California Environmental Quality Act (CEQA) for three independent WSIP projects (referred to herein as the “WSIP Groundwater Projects”): (1) the Chino Basin Program, (2) the Kern Fan Groundwater Storage Project (Kern Fan), and (3) the Willow Springs Water Bank Project (Willow Springs).

Record of Decision, Trump Administration Action 5 Operations Plan for the Central Valley and State Water Projects, per Executive Order 14181

U.S. Bureau of Reclamation (USBR) | December 4th, 2025

On January 24, 2025, President Donald J. Trump issued Executive Order 14181 “Emergency Measures To Provide Water Resources In California And Improve Disaster Response I

On January 24, 2025, President Donald J. Trump issued Executive Order 14181 “Emergency Measures To Provide Water Resources In California And Improve Disaster Response In Certain Areas.” A Presidential Memorandum titled “Putting People Over Fish” was signed four days before the Executive Order and references a reliable water supply, but the specific direction to the CVP is found in Executive Order 14181. Section 2 of Executive Order 14181 requires, among other measures, (c) The Secretary of the Interior, including through the Bureau of Reclamation, shall utilize his discretion to operate the CVP to deliver more water and produce additional hydropower, including by increasing storage and conveyance, and jointly operating federal and state facilities, to high­need communities, notwithstanding any contrary State or local laws. The Bureau of Reclamation shall take all available measures to ensure that State agencies — including the California Department of Water Resources — do not interfere with the Bureau of Reclamation’s operation of the project to maximize water delivery to high­need communities or otherwise, including but not limited to the issuance of a new Record of Decision maximizing water deliveries and consistent with the 2020 Record of Decision. Subsection (g) calls for a “proposed plan, for review by the Secretaries, to appropriately suspend, revise, or rescind any regulations or procedures that unduly burden such projects and are not necessary to protect the public interest or otherwise comply with the law.” This ROD implements initial actions in response to Executive Order 14181.

Relationship of Delta Cross Channel Gate Operations to Loss of Juvenile Winter-run Chinook Salmon at the CVP/SWP Delta Facilities

California Department of Fish and Wildlife (CDFW) | July 1st, 2003

Winter-run Chinook salmon are distinguishable from the three other Chinook runs in the Sacramento River system by the timing of their upstream migration and spawning. Due

Winter-run Chinook salmon are distinguishable from the three other Chinook runs in the Sacramento River system by the timing of their upstream migration and spawning. Due to precipitous decline in the population from the late 1960’s through the late 1980’s, NOAA Fisheries listed the run as “threatened” in August 1989, and subsequently reclassified the run as “endangered” in 1992. The state of California listed the run as endangered in 1989.  Many factors contributed to the decline in the winter-run Chinook population. Among these factors, operation of the federal Central Valley Project and State Water Project has had continuing impacts on winter-run Chinook. Of particular concern have been the direct entrainment losses of juvenile winter-run Chinook at the project export facilities in the Delta. 

Report on the Delta Drought Response Pilot Program for Water Year 2023

This report describes the 2023 Delta Drought Response Pilot Program (DDRPP/Program), provides an analysis of the Program’s effectiveness, and describes the Program outcomes, including findings and recommendations for application in future agricultural water conservation programs. The DDRPP launched in January 2022 as a response to the continuing risk of drought in the Sacramento-San Joaquin Delta Watershed. This report focuses on the results of the 2023 Program, with a brief analysis comparing both years of the Program. For detailed information on the 2022 Program and 2022 analysis, see the 2022 DDRPP Final Report (Sacramento-San Joaquin Delta Conservancy, 2023).
