On May 16, 2008, the U.S. Bureau of Reclamation and the California Department of Water Resources asked the Service to initiate consultation on the Long-Term Operational Criteria and Plan (OCAP) for coordination of the Central Valley Project and State Water Project, specifically concerning the delta smelt and its critical habitat. (See OCAP Legal Archives.) On December 15, 2008, the Fish & Wildlife Service issued a biological opinion (BO) on the Long-Term Operational Criteria and Plan (OCAP) for coordination of the Central Valley Project and State Water Project. The Service determined that the continued operation of these two water projects, as described in the plan, was likely to jeopardize the continued existence of the delta smelt and adversely modify its critical habitat. The inclusion by the Service of reasonable and prudent alternatives, and their acceptance by the water agencies, avoided jeopardy and adverse modification.

Bulletin 250: Fish Passage Improvement: An Element of CALFED’s Ecosystem Restoration Program

California Department of Water Resources (DWR) | June 16th, 2005

Since the 1800s, salmon and steelhead spawning habitat in California has declined 95 percent, from 6,000 miles of rivers and streams to 300 miles. With this decline in spawning habitat, there has been a decrease in salmon and steelhead fish populations. Recognizing the importance of saving and restoring the populations of salmon and steelhead, many government and private organizations have responded, working to reopen streams and  rivers to anadromous fish. Initiated by the California Bay-Delta Program agencies in 1999, the Fish Passage Improvement Program, an element of the Ecosystem Restoration Program1 is a partnership-building effort to improve and enhance fish passage in Central Valley and Bay Area rivers and streams. We work under the guidance of the U.S. Fish and Wildlife Service, National Marine Fisheries Service, and the Department of Fish and Game through an interagency team that provides oversight for the program. In addition, we work with other local, state, and federal agencies and stakeholders to plan and implement projects to remove barriers that impede migration and spawning of anadromous fish. One purpose of the Fish Passage Improvement Program is to identify potential fish passage projects for implementation by the California Bay-Delta agencies and local interests. In order to do that, it is necessary to determine where fish passage impediments exist and to determine what fish passage improvement projects are already in motion. The inaugural issue of Bulletin 250 identifies potential fish passage impediments and ongoing activities that are addressing fish passage barriers within the Fish Passage Improvement Program geographic scope and beyond (Figure ES-1). Chapter 1 gives a historical perspective of fish passage improvement in California, describing the Fish Passage Improvement Program and the efforts to solve the problem outlined in Chapter 2. Chapter 2 describes the historical and current distribution of salmon and steelhead listed as threatened or endangered and their critical habitat in the Central Valley and Bay Area. It also describes how man-made structures in rivers and streams cause problems for fish passage. Chapter 3 describes fish populations and their habitat in Central Valley and Bay Area streams and rivers where the Fish Passage Improvement Program supports projects. Chapter 4 describes projects supported by the Fish Passage Improvement Program or other agencies on streams listed in Chapter 3.

California Salmonid Stream Habitat Restoration Manual

The first edition of this manual, written by Gary Flosi and Forrest Reynolds, and published in 1991, formally synthesized and described the Department of Fish and Game's approach and technical methods for anadromous salmonid habitat restoration. From 1991 through 1994 the first edition was broadly distributed and used as a "standard methods" text by many habitat restoration and resource inventory workers. As a result, many suggestions for improvement of the manual were received by the authors. The second edition, by Flosi and Reynolds was supported by a team that included the authors of this third edition, and was published in October of 1994. The second edition included a number of revisions: 1) a reorganization of sections for project planning and project implementation; 2) the just then recently revised stream channel classification system developed by David Rosgen; 3) a new monitoring and evaluation section; 4) a listing of all databases used for resource inventory and analysis as presented in the manual; 5) a protocol for a large woody debris inventory; 6) a description of required environmental review processes and permits; 7) an expanded and updated listing of sensitive species; and 8) numerous editorial changes to text and data forms. The third edition, like the second, incorporates changes recently developed in the practice of stream habitat inventory and restoration. The authorship list has changed with this edition to more accurately reflect the contributions of the writing team members. The manual is presented in binder form in this edition to more easily and economically incorporate future additions and developments as they evolve. This fourth edition incorporates all changes, corrections, and revisions of this manual up to July 2010. The manual continues in binder form in this edition to easily and economically incorporate future additions and developments as they evolve. The authors anticipate the continued widespread distribution and use of this manual will promote the implementation of the restoration techniques. Readers should also be aware that computer data entry and data summary programs are available upon request for all data collection protocols presented in this manual. Updates to this manual are available on line at http://www.dfg.ca.gov/fish/Resources/HabitatManual.asp.

SWAP 2015 provides an ecosystem approach for conserving California’s fish and wildlife resources by identifying strategies intended to improve conditions of Species of Greatest Conservation Need (SGCN) and the habitats upon which they depend (see Figure 1 of the Executive Summary). CDFW designed SWAP 2015 to guide resource managers, conservation partners, and the public in how they can directly or indirectly participate in conserving California’s precious natural heritage. This section provides an overview of the structure of SWAP 2015 to help readers navigate through the document and find information. SWAP 2015 is organized as follows: Executive Summary provides a summary of: the vision for wildlife conservation in California; statewide goals; the process used to develop conservation strategies based on an ecosystem approach; conservation targets and strategies for seven provinces and anadromous fish; statewide summary; plans for integration and implementation; and process for adaptive management and monitoring. Chapter 1 provides an introduction to SWAP 2015. The challenge of sustaining biodiversity, a summary of CDFW responsibility, and the vision for California wildlife conservation are described. Chapter 1 also explains the requirements for updating SWAP, summarizes major changes since the original 2005 SWAP, and describes the analytical approach used in the 2015 update. Chapter 2 describes California’s natural diversity, identifies SGCN and the criteria used to evaluate species and habitat conditions, and addresses major pressures and stresses currently affecting the SGCN and their habitats. Chapter 3 describes the existing conservation approaches in the state, including the major regulations protecting natural resources, CDFW planning tools, and major conservation programs. Chapter 4 presents the statewide goals of SWAP 2015 and broad, state-level conservation strategies that will be implemented to achieve the desired conservation outcomes. Chapter 5 is divided into seven sections that describe for each geographic province the conservation targets, SGCN and other focal species, KEAs, stresses, pressures, and conservation strategies, including goals and objectives for the provinces. Chapter 6 focuses on conservation strategies developed for anadromous fish in California. Chapter 7 describes how SWAP 2015 will be integrated with other programs and coordinated with partners for the implementation, including through companion plans. Chapter 8 describes the monitoring plan for the conservation strategies, including the mandate for CDFW to use monitoring and adaptive management. It also presents a summary of the effectiveness evaluation of how SWAP 2005 was implemented. The chapter describes how the recommendations from the SWAP 2005 evaluation have been integrated into SWAP 2015. Rationales for selecting conservation strategies presented in SWAP 2015 and a framework for monitoring the effectiveness of the strategies are also described. Chapter 9 provides the list of preparers of SWAP 2015. Chapter 10 provides bibliographic references used in each chapter. Chapter 11 provides a glossary of major terms used in SWAP 2015. Several appendices accompany SWAP 2015 to provide more detailed information and extensive tables that support the document. Database files created during the development of SWAP 2015 to compile and evaluate ecological information and to create strategies can be accessed at: http://www.dfg.ca.gov/SWAP/.

Central Valley Flood Protection Plan Appendix K. Synthesis of Fish Migration Improvement Opportunities in the Central Valley Flood System

California Department of Water Resources (DWR) | July 14th, 2016

Many instream structures in the Central Valley adversely affect native anadromous fish migration. These structures, often referred to as fish passage barriers, reduce or eliminate longitudinal habitat connectivity; prevent or limit access to critical spawning, rearing, and refuge habitat; create migration delays; and create lethal or sublethal conditions for native anadromous species (California Department of Water Resources [DWR] 2012a, 2014; National Marine Fisheries Service [NMFS] 2014). Fish passage barriers associated with the Central Valley flood system trigger compliance requirements under the federal and California Endangered Species Acts; necessitate recurring fish rescues; and impel additional permitting requirements, such as long-term mitigation (NMFS 2009; Vogel 2011; DWR 2012b; Johnson and Vincik 2012; Cannon 2013; Heise 2013; Hendrick and Swart 2013).  Identification of migration impediments and associated improvement opportunities in the flood system is needed for integrated flood management planning. Fish migration improvements can be integrated into flood risk reduction projects1 to yield cost efficiencies in the project planning and implementation phases, and they may result in long-term economic and environmental benefits (DWR 2014). Two documents, the Fish Passage Assessment (Attachment 9C of the Central Valley Flood Protection Plan [CVFPP]) and the Draft Central Valley Flood System Fish Migration Improvement Opportunities (FMIO) report have been prepared to assist in identifying and prioritizing fish migration improvement opportunities in the flood system. 

Central Valley Flood Protection Plan Conservation Strategy 2022 Update

The Central Valley Flood Protection Plan (CVFPP) Conservation Strategy (Conservation Strategy or Strategy) is a primary component of the CVFPP in accordance with the Central Valley Flood Protection Act of 2008. It aligns with and contributes to the attainment of all CVFPP goals, while focusing on improving ecosystem quality, quantity, function, and sustainability within the Systemwide Planning Area (SPA). Its purpose is to provide actionable and measurable targets to improve riverine, aquatic, wetland, and riparian habitat in the flood system through the integration of ecological principles with flood risk reduction projects, operation and maintenance activities, institutional support, and other means (e.g., the remediation of fish passage barriers). The Conservation Strategy also provides data, information, and guidance to floodplain managers to assist in the development of multi-benefit flood infrastructure improvement projects by integrating project components and management strategies that benefit native species and their habitats.

In 2014, the California Natural Resources Agency and the U.S. Department of the Interior asked the authors of this paper, as four former leaders of The Delta Science Program, to summarize the challenges faced by water supply and ecological resource managers in this critically important region of Northern California. They concluded that the challenges are so complex as to meet the definition of a “wicked” problem. Such problems can’t be ignored, defy straightforward characterization, and have no simple solutions. Yet they must be actively managed to maximize beneficial and minimize adverse outcomes. In this context, the following paper calls for Delta management to become more nimble and better coordinated.
