Initial Alternatives Information Report for the North/Central Delta Improvement Study (Delta Cross Channel, Franks Tract, and Through- Delta Facility Evaluation) Initial Alternatives Information Report for the North/Central Delta Improvement Study (Delta Cross Channel, Franks Tract, and Through- Delta Facility Evaluation) U.S. Department of the Interior Bureau of Reclamation February 2009 (Revised February 2010) Mission Statements The mission of the Department of the Interior is to protect and provide access to our Nation’s natural and cultural heritage and honor our trust responsibilities to Indian Tribes and our commitments to island communities. The mission of the Bureau of Reclamation is to manage, develop, and protect water and related resources in an environmentally and economically sound manner in the interest of the American public. Initial Alternatives Information Report for the North/Central Delta Improvement Study (Delta Cross Channel, Franks Tract, and Through- Delta Facility Evaluation) U.S. Department of the Interior February 2009 Bureau of Reclamation (Revised February 2010) Executive Summary The U.S. Department of the Interior (Interior) Bureau of Reclamation (Reclamation) and the California Department of Water Resources (DWR) are evaluating the feasibility of using conveyance and operations actions in the north and central region of the Sacramento–San Joaquin River Delta (Delta) to improve water quality and fish conditions. Specifically, Reclamation is evaluating the feasibility of these actions in the North/Central Delta Improvement Study (NoCDIS or Study). The Initial Alternatives Information Report (IAIR) identifies, discusses, and screens measures to address the problems and opportunities. These measures are used to develop initial alternatives. Initial alternatives from the IAIR will be incorporated into and refined in the subsequent Plan Formulation Report (PFR). Subject to continued appropriations and a determination of federal interest, the Study should culminate in an Environmental Impact Statement/Environmental Impact Report (EIS/EIR) and a Feasibility Report. Reclamation is the federal lead agency for National Environmental Policy Act (NEPA) compliance, and DWR is the state lead agency for California Environmental Quality Act (CEQA) compliance. Purpose and Scope of Report The purpose of this IAIR is to identify the initial alternatives that will be carried forward for additional analysis in the plan formulation and feasibility phases of the Study. Reclamation has completed technical studies that provide the information required for the analyses performed in this IAIR. More detailed alternatives will be developed from these initial alternatives during the next phases of the Study. The IAIR will accomplish the following: • Describe present and future baseline conditions • Identify problems and opportunities • Set forth purpose and need and planning objectives • Formulate a range of measures for the project • Combine those measures into alternative plans Complete alternatives that address the planning objectives are discussed in the IAIR, as well as the related potential environmental impacts and results of initial screening. A comparison of alternatives is provided to refine the alternatives that will be considered further in subsequent steps of the planning process. Based on this evaluation, the IAIR identifies a potential federal interest in the NoCDIS project. ES-1 Executive Summary Study Authorization The CALFED Bay-Delta Authorization Act of 2004 (Public Law 108-361, Section 103) authorizes the Secretary of the Interior to carry out feasibility studies (via Reclamation), as follows: • Section 103(d)(2) Conveyance (B) North Delta Actions: “(i) evaluation and implementation of improved operational procedures for the Delta Cross Channel to address fishery and water quality concerns. (ii) evaluation of a screened through-Delta facility on the Sacramento River.” • Section 103(f)(1) Conveyance (C) Franks Tract “Funds may be expended for feasibility studies and actions at Franks Tract to improve water quality in the Delta.” Reclamation chose to study these actions to determine if the actions could, alone or in combination, meet the study objectives. Study Area The Study area, shown in Figure ES-1, involves sections of the north, central, and south Delta, including the waterways around Franks Tract, the Sacramento River, the South Fork of the Mokelumne River, the Delta Cross Channel, and the lower San Joaquin River. Much of the land within the Study area is subject to agricultural activities, while the waterways provide recreational opportunities; valuable wildlife habitat; and serve as major residential, municipal, and agricultural water supplies to much of the state. Water Resources Problems, Needs, and Opportunities This IAIR has been developed to address two specific problems in the Study area. The first problem to be addressed is quality of water in the south Delta being pumped at the Jones Pumping Plant and the Banks Pumping Plant. The second problem is fisheries conditions throughout the Delta. Water quality in the south Delta has been affected by salinity from tidal intrusion and farming runoff, pesticides, and selenium primarily from agricultural drainage, and mercury from historic mining operations in the Delta watershed. Currently, the interior Delta water quality standards, established by D-1641, are difficult to achieve due to the complex hydrodynamics of the Delta and present Central Valley Project /State Water Project (CVP/SWP) operations. Current water quality problems in the Delta may be further exacerbated due to future demands on a fixed water supply and other factors.

ES-4 Executive Summary Additionally, recent, unprecedented declines of pelagic and anadromous fish have led to listings of several species under the state and federal Endangered Species Acts, court-ordered shutdowns of water diversions, and millions of dollars spent on associated legal proceedings. Reclamation, through NoCDIS, is investigating the opportunities to both reduce salinity levels and improve fishery conditions throughout the Delta. Since the Flooded Islands Pre-Feasibility Study in 2005, DWR’s Bay-Delta Office has continued technical studies, conceptual designs, cost estimates, and water quality modeling in support of facilities at Franks Tract for water quality and fisheries benefits. These pre-feasibility-level studies have resulted in five alternatives. In addition to the Franks Tract alternatives, Reclamation’s NoCDIS Plan of Study (August 2007) included other alternatives in the north and central Delta with similar potential to meet the planning objectives. For the IAIR, alternatives have been identified, evaluated, and screened to determine which has the highest potential benefit to both water quality and fisheries. These opportunities include facilities in the north and central Delta initiated by CALFED or DWR, as well as water management opportunities to meet NoCDIS planning objectives. Objectives and Resource Management Measures The objectives of the NoCDIS are to: 1. Improve water quality at the south Delta export facilities while remaining consistent with long-term Delta planning efforts. 2. Improve fisheries conditions throughout the Delta while remaining consistent with long-term Delta planning efforts. Resource Management Measures were identified to meet each of the two objectives of the project. Measures were developed in the IAIR phase by collecting information on past projects and studies based on some studies already completed by DWR. Some measures were eliminated because they were deemed infeasible or did not best meet the Study’s objectives. The measures retained for further consideration were combined into a set of initial alternatives. The challenge faced in developing the alternatives was to balance the need to deliver freshwater with maintaining and improving fish habitat. Improved water quality at the south Delta export facilities could be achieved by reducing or mitigating the salinity intrusion into the central Delta from the west (from the Pacific Ocean). Several measures were identified as having the potential to meet the first objective: 1.1 Increase transfer of Sacramento River flows to the central Delta. 1.2 Increase Mokelumne River flows delivered to the central and south Delta. ES-5 Executive Summary 1.3 Reduce tidal and seasonal mixing from the western Delta into Franks Tract. 1.4 Increase the net outflow in the lower San Joaquin River near Jersey Point. 1.5 Isolate a “fresh water corridor” minimizing mixing with western Delta waters. 1.6 Create a longer path for higher salinity water to reach export facilities by creating physical flow barriers. Several measures were identified

  • Winter Chinook Salmon in the Central Valley of California: Life History and Management
    Winter Chinook salmon in the Central Valley of California: Life history and management Wim Kimmerer Randall Brown DRAFT August 2006 Page ABSTRACT Winter Chinook is an endangered run of Chinook salmon (Oncorhynchus tshawytscha) in the Central Valley of California. Despite considerablc efforts to monitor, understand, and manage winter Chinook, there has been relatively little effort at synthesizing the available information specific to this race. In this paper we examine the life history and status of winter Chinook, based on existing information and available data, and examine the influence of various management actions in helping to reverse decades of decline. Winter Chinook migrate upstream in late winter, mostly at age 3, to spawn in the upper Sacramento River in May - June. Embryos develop through summer, which can expose them to high temperatures. After emerging from the spawning gravel in -September, the young fish rear throughout the Sacramento River before leaving the San Francisco Estuary as smolts in January­ March. Blocked from access to their historical spawning grounds in high elevations of the Sacramento River and tributaries, wintcr Chinook now spawn below Kcswick Dam in cool tail waters of Shasta Dam. Their principal environmental challcnge is temperature: survival of embryos was poor in years when outflow from Shasta was warm or when the fish spawned below Red Bluff Diversion Dam (RBDD), where river temperature is higher than just below Keswick. Installation of a temperature control device on Shasta Dam has reduccd summer temperature in the discharge, and changes in operations of RBDD now allow most winter Chinook access to the upper river for spawning.

  • 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.

  • 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.
