Lindsey Foreword The Sacramento-San Joaquin Delta (Delta) is a major source of drinking water for 25 million people of the State of California. Therefore, the quality of Delta water is an important consideration for its use as a drinking water source. However, Delta water quality may be degraded by a variety of sources and environmental factors. Close monitoring of Delta waters is necessary to ensure delivery of high quality source waters to urban water suppliers. The Municipal Water Quality Investigations (MWQI) Program, within the Department of Water Resources, is responsible for the monitoring and research of drinking water quality in the Delta. Among all State and local agencies monitoring the Delta and its tributaries, MWQI conducts the only monitoring program to investigate the quality of source waters in the Delta with respect to its suitability for the production of drinking water. Since 1983, the MWQI Program has been conducting comprehensive and systematic source water monitoring in the Delta region. Data and findings are presented for major water quality constituents, including organic carbon, bromide, salinity, regulated organic and inorganic constituents in drinking water, and a few unregulated constituents of current interest. The Real Time Data Forecasting-Comprehensive Program (RTDF-CP) focuses on providing a single location that compiles and disseminates real-time drinking water quality data gathered across agencies. This data enables water managers to make operating decisions based on observed and forecasted changes in water quality. The RTDF-CP includes a network of real-time water quality monitoring stations and a modeling component intended to allow greater predictive ability of water quality in real-time and the future. This and other MWQI Program reports are available online at the MWQI website: http://www .wq. water.ca.gov/mwqi/pubs.cfm For more information about the MWQI Program, please visit our homepage at http://www.wq.water.ca.gov/mwqi/mwqi index.cfm A Summary of the MWQI Program History and Studies 1983-2012 The Municipal Water Quality Program (MWQP) Branch currently consists of four sections. Three of these sections, MWQI, Water Quality Special Studies, and Field Support, constitute the Municipal Water Quality Investigations Program funded by the State Water Project Contractors Authority (SWPCA).

  • A Century of Delta Salt Water Barriers

    A Century of Delta Salt Water Barriers

    A Century of Salt Water Barriers in the Delta By Tim Stroshane Policy Analyst Restore the Delta June 5, 2015 edition Since the late 19th century, California’s basic plan for water resource development has been to export water from the Sacramento River and the Delta to the San Joaquin Valley and southern California. Unfortunately, this basic plan ignores the reality that the Delta is the very definition of an estuary: it is where fresh water from the Central Valley’s rivers meets salt water from tidal flow to the Delta from San Francisco Bay. Productive ecosystems have thrived in the Delta for millenia prior to California statehood. But for nearly a century now, engineers and others have frequently referred to the Delta as posing a “salt menace,” a “salinity problem” with just two solutions: either maintain a predetermined stream flow from the Delta to Suisun Bay to hydraulically wall out the tide, or use physical barriers to separate saline from fresh water into the Delta. While readily admitting that the “salt menace” results from reduced inflows from the Delta’s major tributary rivers, the state of California uses salt water barriers as a technological fix to address the symptoms of the salinity problem, rather than the root causes. Given complex Delta geography, these two main solutions led to many proposals to dam up parts of San Francisco Bay, Carquinez Strait, or the waterway between Chipps Island in eastern Suisun Bay and the City of Antioch, or to use large amounts of water—referred to as “carriage water”— to hold the tide literally at bay.
  • C a S E S T U D Y R E P O R T Sherman Island Delta

    C a S E S T U D Y R E P O R T Sherman Island Delta

    C A S E S T U D Y R E P O R T SHERMAN ISLAND DELTA PROJECT November 2013 Written by Bradley Angell, Richard Fisher & Ryan Whipple a project of Ante Meridiem Incorporated with the direct support of the Delta Alliance International Foundation © 2013 Ante Meridiem Incorporated ABSTRACT This report is an official beginning to a model design for Sherman Island, an important land mass that lies at the meeting point of the Sacramento and San Joaquin Rivers of the California Delta system. As design is typically dominated by a particular driving discipline or a paramount policy concern, the resulting decision-making apparatus is normally governed by that discipline or policy. After initial review of Sherman Island, such a “single” discipline or “principle” policy approach is not appropriate for Sherman Island. At this critical physical place at the heart of California Delta, an inter-disciplinary and equal-weighted policy balance is necessary to meet both the immediate and long-term requirements for rehabilitation of the project site. Exhibiting the collected work of a small team of design and policy specialists, the Case Study Report for the Sherman Island Delta Project outlines the multitude of interests, disciplines and potential opportunities for design expression on the selected 1,000 acre portion of Sherman Island under review. Funded principally by a generous grant from the Delta Alliance, the team researched applicable uses and technologies with a pragmatic case study approach to the subject, physically documenting exhibitions of each technology as geographically close to the project site as possible. After study and on-site documentation, the team compiled this wealth of discovery in three substantive chapters: a site characterization report, the stakeholders & goals assessment, and a case study report.
  • Sherman Island Wetland Restoration Project (Project) Is Composed of Two Phases

    Sherman Island Wetland Restoration Project (Project) Is Composed of Two Phases

    Section 5: Project Description 1. Project Objectives: The Sherman Island Wetland Restoration Project (Project) is composed of two phases. The first phase includes constructing a 700 acre wetland restoration area on the west side of the Antioch Bridge and the second phase includes constructing a 1000 acre wetland restoration area on the northeast side of the Antioch Bridge. This Project also incorporates elements of uplands and riparian forest, on the perimeter and on upland areas, including berms and islands. There are no aspects of this project that are required by law or permit condition, thus this project is truly “Additional”. Furthermore, since Sherman Island is significantly subsided, with land elevations between 10 and 25 feet below sea level, all sequestered GHG will be “Permanent”. Subsided Delta islands are like bowls and if tule wetlands are constructed and permanently flooded, these bowls over time will fill up with rhizome root material (or Carbon). And if these lands are flooded permanently, and agricultural activities do not subject the peat material to oxygen or fertilizers, the underlying peat will not continue to emit GHG into the atmosphere and allow subsidence. Some potential risks to “Permanence” would include fire and land management changes that would convert these wetlands back into agricultural fields. However, fire risk is greatly diminished since these projects will be permanently flooded and since DWR owns this property, the likelihood of returning these lands to agriculture is remote. Lastly, the flood risk on Sherman Island is significant but if this were to occur, the carbon sequestered would be under water and essentially capped, with very little GHG release.
  • Subsidence Reversal for Tidal Reconnection

    Subsidence Reversal for Tidal Reconnection

    PERFORMANCE MEASURE 4.12: SUBSIDENCE REVERSAL FOR TIDAL RECONNECTION Performance Measure 4.12: Subsidence Reversal for Tidal Reconnection Performance Measure (PM) Component Attributes Type: Output Performance Measure Description 1 Subsidence reversal 0F activities are located at shallow subtidal elevations to prevent net loss of future opportunities to restore tidal wetlands in the Delta and Suisun Marsh. Expectations Preventing long-term net loss of land at intertidal elevations in the Delta and Suisun Marsh from impacts of sea level rise and land subsidence. Metric 1. Acres of Delta and Suisun Marsh land with subsidence reversal activity located on islands with large areas at shallow subtidal elevations. This metric will be reported annually. 2. Average elevation accretion at each project site presented in centimeters per year. This metric will be reported every five years. Baseline 1. In 2019, zero acres of subsidence reversal on islands with large areas at shallow subtidal elevations. 2. Short-term elevation accretion in the Delta at 4 centimeters per year. 1 Subsidence reversal is a process that halts soil oxidation and accumulates new soil material in order to increase land elevations. Examples of subsidence reversal activities are rice cultivation, managed wetlands, and tidal marsh restoration. DELTA PLAN, AMENDED – PRELIMINARY DRAFT NOVEMBER 2019 1 PERFORMANCE MEASURE 4.12: SUBSIDENCE REVERSAL FOR TIDAL RECONNECTION Target 1. By 2030, 3,500 acres in the Delta and 3,000 acres in Suisun Marsh with subsidence reversal activities on islands, with at least 50 percent of the area or with at least 1,235 acres at shallow subtidal elevations. 2. An average elevation accretion of subsidence reversal is at least 4 centimeters per year up to 2050.
  • Delta Region Drinking Water Quality Management Plan

    Delta Region Drinking Water Quality Management Plan

    DELTA REGION DRINKING WATER QUALITY MANAGEMENT PLAN DRAFT FINAL June 2005 Funding for this project was made possible by a CALFED Grant through the Drinking Water Quality Program This document was funded by the CALFED Water Quality Program as an initial effort to create Regional “Equivalent Level of Public Health Protection” Plans and to assist in establishing a uniform framework in such planning. It is not intended to be a final document. California Bay-Delta Authority and CALFED WQP Implementing Agency staff have not had the opportunity to review and comment on this document, and any opinions or interpretations of the CALFED program expressed within the document are solely those of its authors. The CALFED WQP is committed to working with these and other parties to continue development and refinement of Regional Plans. EXECUTIVE SUMMARY In 2004, the CALFED Bay-Delta Program (CALFED) commissioned a pilot program for development of regional drinking water quality management plans (i) to identify the drinking water quality issues and needs of drinking water agencies in different regions of California and (ii) to develop solutions to address those needs. This Delta Region Drinking Water Quality Management Plan (DRDWQMP) was developed jointly by Contra Costa Water District (CCWD), the city of Stockton (COS), and Solano County Water Agency (SCWA). Figure ES-1 shows the Sacramento-San Joaquin Delta (Delta) region, with an outline representing Delta boundaries as defined in California Water Code Section 12220, along with the service areas of the three participating agencies. These three agencies represent the largest urban water users within the Delta region.
  • Delta Cross Channel Fact Sheet

    Delta Cross Channel Fact Sheet

    U.S. Department of the Interior Bureau of Reclamation California-Great Basin Region Delta Cross Channel Overview The Delta Cross Channel (DCC), located near Walnut Grove, California, is a feature of Reclamation’s Central Valley Project (CVP) Delta Division. The facility is a gate-controlled diversion channel on the east bank of the Sacramento River, about 30 miles downstream of Sacramento. The DCC facilitates the diversion of fresh water from the Sacramento River into the interior Sacramento-San Joaquin River Delta to the CVP and State Water Project (SWP). Background Reclamation completed the DCC in January 1951. The facility is key to maintaining water quality in the central Delta during controlled releases from northern CVP storage reservoirs, such as Shasta and Folsom, through the Delta to the headworks of the CVP’s Delta-Mendota and Contra Costa canals and SWP’s California Aqueduct. The DCC, pictured above, is 6,000-feet long with a bottom width of 210 feet, and a capacity of 3,500 cubic feet per second (cfs). The gates extend about 245 feet across the channel at its mouth on the Sacramento River. Reclamation closes the DCC gates during high water to prevent flood stages in the San Joaquin section of the Delta. After flood danger passes, Reclamation opens the gates to allow Sacramento River water through to the federal and state pumping plants. During certain periods, When the gates are open, the DCC diverts fresh Sacramento River water to Snodgrass Slough. From there it flows through natural the DCC gates can operate frequently and boaters are channels to the CVP’s Jones Pumping Plant and SWP’s Banks advised to check gate status, especially around holidays.
