Transitions for the Delta Economy
Transitions for the Delta Economy January 2012 Josué Medellín-Azuara, Ellen Hanak, Richard Howitt, and Jay Lund with research support from Molly Ferrell, Katherine Kramer, Michelle Lent, Davin Reed, and Elizabeth Stryjewski Supported with funding from the Watershed Sciences Center, University of California, Davis Summary The Sacramento-San Joaquin Delta consists of some 737,000 acres of low-lying lands and channels at the confluence of the Sacramento and San Joaquin Rivers (Figure S1). This region lies at the very heart of California’s water policy debates, transporting vast flows of water from northern and eastern California to farming and population centers in the western and southern parts of the state. This critical water supply system is threatened by the likelihood that a large earthquake or other natural disaster could inflict catastrophic damage on its fragile levees, sending salt water toward the pumps at its southern edge. In another area of concern, water exports are currently under restriction while regulators and the courts seek to improve conditions for imperiled native fish. Leading policy proposals to address these issues include improvements in land and water management to benefit native species, and the development of a “dual conveyance” system for water exports, in which a new seismically resistant canal or tunnel would convey a portion of water supplies under or around the Delta instead of through the Delta’s channels. This focus on the Delta has caused considerable concern within the Delta itself, where residents and local governments have worried that changes in water supply and environmental management could harm the region’s economy and residents. -

Comprehensive Operations Plan and Monitoring Special Study Prepared by the Department of Water Resources and the U.S
August 25, 2019 Comprehensive Operations Plan and Monitoring Special Study Prepared by the Department of Water Resources and the U.S. Bureau of Reclamation In Accordance with the Water Quality Control Plan for the San Francisco Bay/Sacramento- San Joaquin Delta Estuary—December 12, 2018 This Comprehensive Operations Plan (COP) and Monitoring Special Study (MSS) describes current and potential future actions that fully address the impacts of the State Water Project (SWP) and Central Valley Project (CVP) export operations on water levels and flow conditions that may affect salinity conditions in the southern Delta, including the availability of assimilative capacity for local sources of salinity. The COP includes detailed information regarding the configuration and operations of facilities relied upon in the COP and identifies performance goals for these facilities. Comprehensive Operations Plan Current SWP/CVP Operations Exports The Department of Water Resources (DWR) and the U.S. Bureau of Reclamation (Reclamation) operate the State Water Project and Central Valley Project (collectively Projects), respectively, in compliance with the terms and conditions contained in their water rights permits and licenses issued by the State Water Resources Control Board (SWRCB). In December 1999 (and amended in March 2000), the SWRCB issued Water Rights Decision 1641 (D-1641), which amended the associated water rights permits with additional terms and conditions to protect beneficial uses in the Delta. This included assigning responsibility to DWR and Reclamation for meeting specific water quality and flow objectives (DWR, 2006). In addition, DWR and Reclamation must also comply with regulatory requirements, as applicable, contained in, but not limited to: • 2008 U.S. -
Methyl and Total Mercury Spatial and Temporal Trends in Surficial Sediments of the San Francisco Bay-Delta
Methyl and Total Mercury Spatial and Temporal Trends in Surficial Sediments of the San Francisco Bay-Delta Assessment of Ecological and Human Health Impacts of Mercury in the Bay-Delta Watershed CALFED Bay-Delta Mercury Project Final Report Submitted to: Mark Stephenson California Department of Fish and Game Moss Landing Marine Labs 7544 Sandholdt Road Moss Landing, CA 95039 Submitted by: Wesley A. Heim Moss Landing Marine Laboratories 8272 Moss Landing Rd Moss Landing, CA 95039 [email protected] (email) 831-771-4459 (voice) Dr. Kenneth Coale Moss Landing Marine Laboratories 8272 Moss Landing Rd Moss Landing, CA 95039 Mark Stephenson California Department of Fish and Game Moss Landing Marine Labs 7544 Sandholdt Road Moss Landing, CA 95039 EXECUTIVE SUMMARY Recent studies indicate significant amounts of mercury are transported into the Bay-Delta from the Coastal and Sierra mountain ranges. In response to mercury contamination of the Bay-Delta and potential risks to humans, health advisories have been posted in the estuary, recommending no consumption of large striped bass and limited consumption of other sport fish. The major objective of the CALFED Bay-Delta Mercury Project “Assessment of Ecological and Human Health Impacts of Mercury in the Bay-Delta Watershed” is to reduce mercury levels in fish tissue to levels that do not pose a health threat to humans or wildlife. This report summarizes the accomplishments of the Moss Landing Marine Laboratories (MLML) and California Department of Fish and Game (CDF&G) at Moss Landing as participants in the CALFED Bay-Delta Mercury Project. Specific objectives of MLML and CDF&G include: 1. -
