This section provides an overview of the (1) San Francisco Bay Delta watershed, (2) multiple water demands in the watershed, (3) selected laws and agreements related to restoration efforts in the watershed, and (4) funding for restoration efforts in the watershed. The San Francisco Bay Delta watershed is a single, complex ecosystem covering more than 75,000 square miles, almost entirely in California. It includes a diversity of fresh, brackish, and salt water ecosystems. Figure 1 shows the watershed and its three major geographic areas and their subregions. The watershed’s three major geographic areas contain unique, yet inherently interconnected environmental and cultural features and face similar water quality and other threats: San Francisco Bay and its local watershed (Bay). The San Francisco Bay is the large body of mostly salt water through which the local watershed, as well as the entire Bay Delta watershed, drains into the Pacific Ocean. According to U.S. Census data, more than 7 million people live in the nine-county Bay area containing the local watershed—an area with one of the nation’s densest populations. Large cities, such as San Jose, San Francisco, and Oakland; their suburbs, including Silicon Valley; and numerous other cities occupy much of the land surrounding the Bay. Since the California Gold Rush in the mid-1800s, most of the Bay’s historical wetlands have been filled for development or converted to farmland or industrial salt ponds, and the loss of these natural features has removed important barriers for flood and erosion control. Because of its urban setting and location at the downstream end of the watershed, the Bay’s water quality faces threats from numerous sources of pollution, including sewage, trash, urban and industrial runoff (e.g., metals, solvents, and inorganic chemicals), and runoff from agriculture and past mining activities upstream (e.g., nutrients, pesticides, and metals). Sacramento-San Joaquin Delta (Delta). The Sacramento-San Joaquin Delta comprises roughly 1,000 square miles where the fresh waters of the Sacramento and San Joaquin Rivers converge south of the city of Sacramento before flowing into the San Francisco Bay through a network of more than 50 islands. It is a largely rural area that is also home to more than 500,000 people living mostly on its suburban periphery, and its communities and farmland are protected from flooding by approximately 1,100 miles of levees. During the California Gold Rush, settlers diked the Delta’s channels and waterways and began building levees to create dry land, resulting in the loss of nearly all of the original wetlands in the area. As a result, the Delta has been converted from an historic plain of seasonally flooded brackish and freshwater wetlands to a mosaic of channelized waterways surrounding its islands. According to reports, many of these islands have subsequently subsided up to 25 feet below sea level due largely to the use of groundwater and farming, which can cause the islands’ rich peat soil to oxidize and erode. The Delta is a major outdoor recreation destination for activities such as fishing and boating. Its key water quality threats include agricultural, urban, and past mining runoff. In addition, the complex system of water supply infrastructure projects built throughout the watershed diverts fresh water from the Delta to other parts of the state, changing the saltwater content of much of the area’s wetlands and marshes. Upper watershed. The upper watershed is the vast area where the watershed’s rivers, streams, and tributaries originate at the crest of the Sierra Nevada and other mountain ranges and then travel hundreds of miles through California’s Central Valley, the nation’s most productive agricultural area, according to USDA. The upper watershed includes three subregions: the Sacramento River watershed in northern California, through which water generally flows south; the San Joaquin River watershed in central California, through which water generally flows west and then north; and the Tulare Lake Basin in southern California, through which water no longer drains naturally. About 5 million people live throughout the area in a mix of rural and urban communities, including large inland cities, such as Fresno and Sacramento. In the upper watershed, the Sierra Nevada snowpack serves as temporary storage for roughly one-third to one- half of California’s water, depending on the year. Most of the major rivers hold reservoirs to capture and store the snowmelt for longer- term use. As a result of mining, agriculture, and water infrastructure development, the area’s historic water flows have been highly modified, the Central Valley’s historic grasslands and flood plains have been converted to managed wetlands and are often threatened by land subsidence, and runoff from agriculture and past mining activities are dominant threats to water quality in low-lying areas. In the mountains and foothills, forest fires can threaten water quality, mostly by causing erosion that increases sediment in streams. The Bay and Delta together form the San Francisco Bay/Sacramento-San Joaquin Delta Estuary, often referred to as the Bay Delta, one of the largest estuaries in North America. The Bay Delta is the ecosystem created by the mixing of salt water from the Pacific Ocean and fresh water from the Sacramento and San Joaquin Rivers and their tributaries. It provides habitat for about 750 species of plants and animals, including more than 130 species of fish. It also contains more than 700,000 acres of farmland, and millions of users access it each year for recreational activities, such as hunting, boating, and fishing. In contrast to the managed wetlands of the upper watershed, the Bay Delta wetlands are tidal areas—brackish wetland influenced by the push and pull of ocean tides. Even with the tidal influence, the saltwater content of the Bay Delta is also heavily influenced by the amount of fresh water available, much of which is diverted by water supply infrastructure projects and can vary due to multiple water demands. Because of the watershed’s economic, environmental, and cultural importance, it has been the subject of political and legal battles over multiple water demands for decades. Beginning in the 1930s, federal and then state water projects—two complex networks of dams, pumps, reservoirs, canals, and other facilities—have diverted water from the Sacramento and San Joaquin Rivers to agricultural, industrial, and urban consumers in the Bay area and southern parts of California. The federal Central Valley Project primarily diverts water for agricultural use, and the California State Water Project, which was developed in the 1960s, primarily diverts water for drinking and industrial use. Hundreds of water contractors, such as the Westlands Water District and the Metropolitan Water District of Southern California, purchase water from these projects, which can divert about 20 to 70 percent of the natural water flowing into the Bay Delta, depending on legal limits and seasonal levels of precipitation. Other water demands include habitat needs for threatened and endangered species such as the Delta smelt (a fish) and various salmon species. In particular, federal agencies have developed instream flow requirements for these species of fish that require water to be released from dams upstream to help maintain adequate water quality and temperature for the fish. As a result, most of the water in the watershed is managed by federal, state, and local water projects for use by private and investor-owned water agencies and districts and their customers, as well as for fish and habitat purposes. Any proposed changes to this complicated water allocation system—which accounts for California’s largest supply of fresh water—often raise concerns among water users about losing water, receiving reduced priority for water supplies, or obtaining water of poor quality. For example, according to one study, the state of California has allocated more water rights than what could be available naturally. Other concerns involve the system’s infrastructure— the system depends largely on a complex network of aging levees, many of which were first built in the mid-1800s—and the possible effects on water supply and quality. Specifically, earthquakes, floods, subsidence, or sea level rise could cause these levees to fail and put the state’s fresh water supply at risk from saltwater contamination. As a result of these and other concerns, many stakeholders in the watershed have been, and continue to be, involved in legal actions over multiple water demands. Construction and operation of the Central Valley Project and the State Water Project has fundamentally altered the physical environment of the Bay, Delta, and parts of the upper watershed, where nearly every tributary has been dammed to create reservoirs to supply these water projects. By the late 1980s, species decline and water quality problems became so critical in the Bay Delta that stakeholders raised concerns that the continued operation of these projects might be conflicting with federal and state water quality and endangered species laws (discussed below). In 1992, the Central Valley Project Improvement Act amended the Central Valley Project authorizations, which previously focused primarily on certain uses such as irrigation and power generation. The act specifies, among other things, a number of actions for the purposes of protecting, restoring, and enhancing fish, wildlife, and associated habitats in the Central Valley and Trinity River basins in California. The act’s stated purposes include, among other things, to achieve a reasonable balance among competing demands for use of Central Valley Project water, including the requirements of fish and wildlife, agriculture, municipal and industrial and power contractors. Under the act, Reclamation implements several programs, including those to restore habitat on Central Valley rivers and streams, improve diversion facilities to protect certain juvenile fish, and deliver water supplies for critical wetland habitat supporting resident and migratory waterfowl and threatened and endangered species. To address the increasingly complex issues surrounding the Bay Delta, the federal and California state governments reached an agreement to create the CALFED Bay-Delta Program (CALFED) in 1995 to restore ecological health, improve water quality, fortify water management infrastructure, and increase water supply reliability. From 1995 through 2009, about 20 federal and state agencies collaborated through this program, issuing a record of decision in 2000 outlining CALFED goals and programs and implementing federal and state legislation enacted in the early 2000s. Under the National Environmental Policy Act of 1969, agencies issue a record of decision at the end of the environmental impact statement process, which they are required to conduct for major federal actions that have a significant effect on the environment. The 2000 record of decision established a program with 12 components, including water quality and ecosystem restoration, to be managed by state and federal agencies. According to the record of decision, CALFED’s water quality goal was to provide good water quality for the millions of Californians who rely on the Delta for all or a part of their drinking water. CALFED’s goal for ecosystem restoration under the record of decision was to improve aquatic and terrestrial habitats and natural processes to support stable, self-sustaining populations of diverse and valuable plant and animal species through an adaptive management process. This process includes reevaluating or updating goals, activities, or performance measures based on the results of ongoing monitoring and progress assessments. Under the record of decision, the water quality and ecosystem restoration programs include activities throughout the Bay, Delta, and upper watershed. In 2002, California enacted the California Bay-Delta Act, which established the California Bay-Delta Authority to oversee CALFED. In 2004, the Calfed Bay-Delta Authorization Act (CALFED Act), a federal law, implemented the record of decision, directed federal agencies to coordinate CALFED activities with California state agencies, and authorized federal agencies to participate in the California Bay-Delta Authority as nonvoting members for the full duration of the period it continued to be authorized by state law. CALFED received federal appropriations to develop and implement ecosystem protection and restoration projects. Section 105 of the act requires Interior to report annually on the accomplishments of various program components, including those related to additional water storage and ecosystem restoration. Section 106 of the act requires OMB, in coordination with the governor of California, to report annually on all expenditures since 1998 to achieve the program’s objectives. However, in 2009, California repealed the California Bay-Delta Act and abolished the California Bay-Delta Authority, replacing it with the Delta Reform Act and the Delta Stewardship Council. The 2009 law focused state efforts more specifically on the Delta, in part by tasking the council with developing an enforceable Delta Plan for promoting a healthy Delta ecosystem and a more reliable water supply. According to a report by the California Legislative Analyst’s Office, the CALFED federal-state partnership ended due to several challenges, including uncertain financing, weak governance, and a lack of accountability. Although California state law was amended in 2009, the federal CALFED Act has not been significantly amended since its enactment in 2004. As we reported in June 2015, although the CALFED record of decision remains in effect, the state’s future direction for Bay Delta activities are likely to be coordinated through the Delta Plan. The Delta Plan was, under certain conditions, to incorporate a 50-year conservation plan initiated by the state, in cooperation with Reclamation, in 2006. The 50- year plan proposed restoring approximately 150,000 acres of wetlands, grasslands, and other areas in and around the Delta over 50 years and addressing water supply reliability concerns by building two large tunnels to transport fresh water under the Delta. In 2015, facing uncertainties in obtaining permits to implement the plan, the state replaced the 50-year plan with two separate initiatives managed by the California Natural Resources Agency: (1) California EcoRestore, which aims to begin restoring at least 30,000 Delta acres over 5 years, and (2) California WaterFix, which includes building the two tunnels from the 50-year plan. The ecosystem chapter of the Delta Plan is being amended, and the amended chapter is anticipated to be complete by early 2019, according to Delta Stewardship Council officials. While it does not directly incorporate EcoRestore, the Delta Plan ecosystem amendment currently under development acknowledges that EcoRestore’s successful implementation is needed to achieve the restoration objectives in the Delta Reform Act, according to Delta Stewardship Council officials. In addition to the CALFED Act and the Central Valley Project Improvement Act, other federal laws, including water quality and endangered species laws, are relevant to restoration efforts in the watershed. Some relevant laws include the following: The Clean Water Act. The objective of this act is to restore and maintain the chemical, physical, and biological integrity of the nation’s waters. A 1987 amendment to the act created the National Estuary Program to promote comprehensive planning for, and conservation and management of, estuaries of national significance. The National Estuary Program calls for the development of comprehensive conservation and management plans (CCMP) for these designated estuaries, including the Bay Delta estuary, which was designated under the program in 1987. Under the act, EPA also works with California to regulate water quality. In addition, section 404 of the Clean Water Act generally prohibits the discharge of dredged or fill material into waters of the United States without a permit from the Corps. The Corps administers the permitting responsibilities of the section 404 program while EPA develops, in conjunction with the Corps, the substantive environmental criteria that permit applicants must meet. The Endangered Species Act. This act was enacted to, among other things, provide a means to conserve the ecosystem upon which endangered species and threatened species depend and to provide a program for the conservation of such endangered species and threatened species. Under the act, species may be listed as endangered or threatened. Several species in the watershed are listed as threatened or endangered, including the Delta smelt, steelhead trout, spring- and winter-run Chinook salmon, Ridgway’s rail (a bird), salt marsh harvest mouse, red-legged frog, and California tiger salamander. NOAA’s National Marine Fisheries Service and the U.S. Fish and Wildlife Service, depending on the species, implement the act, including by issuing biological opinions regarding the potential effects of proposed federal actions on endangered and threatened species. The San Joaquin River Restoration Settlement Act. In conjunction with the settlement this act implements, it outlines, among other things, measures to achieve the goals of restoration of the San Joaquin River and the successful reintroduction of California Central Valley spring-run Chinook salmon. Under the act, Reclamation is to coordinate several actions, including the expansion of a segment of the San Joaquin River to provide habitat for juvenile salmon. Across the watershed, funding for restoration efforts typically comes from a variety of federal, state, local, nongovernmental, and private entities. According to Interior officials, federal funding includes approximately $37 million per year for CALFED overall and additional funding for implementation of the Central Valley Project Improvement Act, available for certain projects in the Delta and upper watershed. Also, according to Interior officials, the U.S. Geological Survey funds research and monitoring to support water quality management, water operations, and restoration. Additional federal sources of funding include grant programs from EPA, NOAA, and the U.S. Fish and Wildlife Service and projects funded through Reclamation, in addition to funding for water projects that can include a restoration component. For example, Reclamation has provided about $37 million annually since fiscal year 2015 for the San Joaquin River Restoration Program. A number of other federal entities, including USDA’s Natural Resources Conservation Service, also fund restoration projects in the watershed. For example, USDA’s Natural Resources Conservation Service has programs, such as the Environmental Quality Incentives Program and the Agricultural Conservation Easement Program, to support farm conservation efforts throughout the Central Valley. Funding from state sources primarily comes from state water and conservation agencies and is funded through statewide bonds and the state’s general fund. For example, in 2014, California voters authorized $7.5 billion in bonds to fund ecosystems and watershed protection and restoration; water supply infrastructure projects, including surface and groundwater storage; and drinking water protection across the state, including the San Francisco Bay Delta watershed. In addition to the bond funding, in 2016, voters from nine Bay area counties authorized an annual $12 parcel tax that is expected to raise approximately $500 million over 20 years for Bay wetlands restoration, as well as other multi-benefit projects. In the Delta, in addition to federal and state funding for restoration efforts, according to state officials, funding often comes from water contractors that pay for major restoration efforts through their obligations under the State Water Project to address biological opinions issued by federal regulatory agencies for endangered or threatened species. For example, water contractors are responsible for funding restoration efforts under the state’s California EcoRestore initiative, including at least $205 million to restore 8,000 acres of fish habitat and $171 million for 17,000 acres of floodplain improvements. EcoRestore began in 2015, and total costs for projects are expected to reach at least $300 million in the initiative’s first 4 years, according to the California Natural Resources Agency. According to officials from several federal and nonfederal entities, including EPA and the San Francisco Estuary Partnership, no official estimates exist for the expected total future costs to restore the entire watershed, though some estimates have been developed for limited types of activities. For example, regarding cost estimates, the San Francisco Estuary Partnership typically refers to Save the Bay’s 2007 Greening the Bay report, which estimates that it will cost almost $1.5 billion over 50 years to restore the 36,176 acres of Bay shoreline already set aside for restoration. Overall, according to related reports, investments on the order of tens of billions of dollars would likely be necessary to restore the entire watershed. Federal and nonfederal entities, including state agencies and nongovernmental organizations, carry out and coordinate a wide range of restoration efforts in the watershed. These entities coordinate comprehensive restoration efforts in the Bay and Delta primarily through two coordinating bodies—the San Francisco Estuary Partnership and the Delta Plan Interagency Implementation Committee, respectively. In the upper watershed, federal and nonfederal entities do not have a coordinating body for comprehensive restoration efforts, but they do coordinate restoration efforts through plans specific to entities, projects, or restoration topics. In 2009, federal entities first developed an Interim Federal Action Plan for coordinating federal restoration efforts across the entire watershed, but not all of the entities are using the plan. Federal and nonfederal entities carry out a wide range of restoration efforts—i.e., water quality improvement and ecosystem restoration—that can involve multiple entities, vary in geographic scope, span multiple years, and are intended to achieve multiple benefits. According to our review of reports and interviews with officials from federal and nonfederal entities, water quality improvement efforts include projects intended to improve the physical, chemical, or biological characteristics of water, and ecosystem restoration efforts include projects to restore degraded habitats. According to these interviews, restoration efforts can target a range of priorities, including conservation, resiliency, mitigation, monitoring, and enhancement. In addition, these efforts can directly or indirectly support water quality improvement and ecosystem restoration goals and objectives, and they can encompass a variety of activities, such as planning, project selection, project implementation, permitting, funding, technical assistance, and assessment. Figure 2 shows the locations and different habitat types for a number of the completed and ongoing restoration projects implemented by federal and nonfederal entities— partly under the CCMP, California EcoRestore, and other efforts—in the Bay Delta Estuary. Restoration efforts in the watershed can involve multiple levels of government, as well as nongovernmental organizations. For example, the South Bay Salt Pond Restoration Project near San Jose, California—the largest tidal wetland restoration project on the west coast of the United States, according to the project’s website—is a joint effort among the U.S. Fish and Wildlife Service, California Department of Fish and Wildlife, and the California State Coastal Conservancy, along with local governments, donors, consultants, and other participants. Similarly, the Hamilton Wetland Restoration Project near Novato, California, which involves the restoration of tidal and seasonal wetlands, is a joint effort among the Corps, California State Coastal Conservancy—the nonfederal sponsor and landowner—and other federal and nonfederal entities. Restoration efforts in the watershed also vary in geographic scope and can span jurisdictions. The South Bay Salt Pond Restoration Project includes federal and state land and, according to the project’s website, is expected to restore more than 15,000 acres of industrial salt ponds to tidal marsh and other wetland habitats in three counties located along the shores of the southern part of San Francisco Bay. (See fig. 3.) The Hamilton Wetland Restoration Project comprises state-owned land and, according to the California State Coastal Conservancy, has the purpose to restore approximately 2,600 acres to tidal wetland on a former army airfield and adjacent properties along the San Francisco Bay in an area 25 miles north of San Francisco. (See fig. 4.) In contrast, other efforts include project areas on farms. For example, under its Environmental Quality Incentives Program, USDA’s Natural Resources Conservation Service has focused on providing conservation planning, among other services, for farm operators and nonindustrial forestland owners, including tribes. Officials from several federal and nonfederal entities, including EPA, the San Francisco Estuary Partnership, the Central Valley Joint Venture, and the California State Coastal Conservancy, stated that the primary focus of restoration efforts varied from one geographic area to another. For example, according to some of these officials, efforts to restore tidal wetlands are prevalent in the Bay, and efforts to address land subsidence are prevalent in the Delta. (See fig. 5.) Restoration efforts in the watershed can span multiple years. For example, the South Bay Salt Pond Restoration Project is an ongoing, multi-phase, 50-year effort that began with the acquisition of former industrial salt ponds in 2003. Likewise, the Hamilton Wetland Restoration Project is an ongoing, multi-phase effort that began in 1999. In the upper watershed, planning began in 2012 for California EcoRestore’s ongoing Yolo Bypass Salmonid Habitat Restoration and Fish Passage Project, which aims to increase floodplain habitat for endangered and threatened fish species in the Sacramento River watershed. Restoration efforts in the watershed can also have multiple primary benefits. For example, the Hamilton Wetland Restoration Project was designed to reverse years of land subsidence, restore wetlands, reestablish historic habitat for wildlife and endangered species, and beneficially reuse dredged sediment. Multiple benefits could also accrue over time. For instance, according to the California State Coastal Conservancy, while the Hamilton Wetland Restoration Project currently provides habitat for migratory water birds and fish, it is expected to become thickly vegetated with a complex network of tidal channels that provide habitat for several threatened and endangered species. Restoration efforts can also provide multiple secondary benefits. For example, restoring wetlands may provide resilience against sea level rise, habitat for wildlife, and an area for recreation. Federal and nonfederal entities coordinate comprehensive restoration efforts in the Bay and Delta through the San Francisco Estuary Partnership and the Delta Plan Interagency Implementation Committee, respectively. In the upper watershed, federal and nonfederal entities coordinate specific restoration efforts through plans specific to entities, projects, or restoration topics. Specifically: Bay. In the Bay, federal and nonfederal entities coordinate comprehensive restoration efforts through the San Francisco Estuary Partnership. The partnership was established in 1987 and receives funding from EPA’s National Estuary Program to implement the CCMP for the San Francisco Estuary (i.e., the Bay Delta). The partnership’s members include federal, state, and local government entities; nongovernmental organizations, such as conservation groups; and a utility commission. The partnership’s members provided input on developing and revising the CCMP and have integrated goals into the CCMP from their own topic- or entity-specific strategic plans. Partnership members also coordinate restoration efforts guided by the CCMP. For example, the U.S. Fish and Wildlife Service, U.S. Geological Survey, the California State Coastal Conservancy, and the California Department of Fish and Wildlife work to coordinate on managed wetlands and ponds—one of the restoration efforts outlined in the CCMP. Furthermore, partnership members may carry out various activities for restoration projects in the Bay, such as project planning, regulating and permitting (e.g., for dredging and extracting sediment), on-the-ground project implementation, and scientific monitoring. Partnership members meet quarterly and participate in a conference every 2 years to provide updates on the status of projects, share scientific research, and present monitoring results. Delta. In the Delta, federal and nonfederal entities coordinate comprehensive restoration efforts through the Delta Plan Interagency Implementation Committee. This committee was created in 2013 by the Delta Stewardship Council, the state agency responsible for overseeing the Delta Plan—the state’s plan for promoting a more reliable water supply and a healthy ecosystem. The committee is made up of representatives from 7 federal and 11 state entities and helps implement the Delta Plan. Members of the committee may also carry out various activities for restoration projects in the Delta, such as scientific monitoring, on-the-ground project implementation, project planning, and regulating and permitting (e.g., for placing materials such as concrete structures or rocks into the water to support levees). The committee meets twice a year and participates in conferences to gather scientific consensus or to share recent research. Some committee members are also members of the San Francisco Estuary Partnership and coordinate separately through initiatives that may have predated the committee and that are specific to entities, projects, or restoration topics. Upper watershed. In the upper watershed, while federal and nonfederal entities do not have a coordinating body for comprehensive restoration efforts, they coordinate restoration efforts through plans specific to entities, projects, or restoration topics. For example, 20 federal, state, and nongovernmental entities coordinate through the Central Valley Joint Venture—a partnership with the mission to conserve migratory bird habitat—and its implementation plan. Likewise, dozens of federal, state, and local government entities coordinate to implement the Central Valley Flood Protection Plan, a plan adopted by California’s Central Valley Flood Protection Board for managing flood risk. In addition, NOAA, the U.S. Fish and Wildlife Service, and the California Department of Fish and Wildlife coordinate on implementing a conservation strategy in parts of the Central Valley. A federal memorandum of understanding and an Interim Federal Action Plan outline how federal entities are to coordinate the federal government’s restoration activities and support state efforts across the entire watershed. The California Bay-Delta Memorandum of Understanding among Federal Agencies, signed in September 2009, established a Federal Bay-Delta Leadership Committee to coordinate federal efforts related to restoration and water management across the entire watershed while the state structure was transitioning from the California Bay-Delta Authority to the Delta Stewardship Council, and the state therefore was no longer participating in the originally structured CALFED federal-state partnership. According to the memorandum, this federal committee was to be led by Interior and CEQ and to meet regularly. The signatories of the memorandum also agreed to develop a federal work plan to outline near-term federal actions and begin to identify and prioritize key longer-term federal actions for restoration efforts and water management across the watershed. The entities issued an Interim Federal Action Plan in December 2009. The Interim Federal Action Plan organizes federal actions into four priorities, including working with state and local authorities on joint project planning to ensure healthy Bay Delta ecosystems and to improve water quality. Specifically, the federal entities agreed to build projects to improve water supply, including through conservation efforts in municipal areas and on agricultural lands; to fund habitat restoration projects for threatened and endangered fish across the watershed; and to assess the effects of pollutants such as mercury and pesticides on water quality. According to the Interim Federal Action Plan, these priorities cut across different federal entities’ missions and activities in the watershed. Further, the Interim Federal Action Plan includes actions aimed at ensuring the effective and efficient use of federal resources, such as by leveraging nonfederal resources. In late 2010, the agencies that signed the memorandum provided a status update on the Interim Federal Action Plan that confirmed the federal government’s support of state efforts in the watershed. The status update directs the federal government to review the components of any proposed restoration plan and understand the costs and benefits such a plan would have on federal water resources and taxpayers. The President’s fiscal year 2019 budget, which sets the administration’s top- level priorities and was released in February 2018, reaffirmed the federal government’s commitment to the Interim Federal Action Plan and stated that the plan is under the leadership of CEQ, Interior, and the Delta Stewardship Council. OMB staff stated the Interim Federal Action Plan provides overall guidance to federal agencies and clarifies that the agencies should focus their various actions in the watershed on the plan’s four priorities, including while working with nonfederal entities through collaborative bodies. Nonetheless, not all federal entities are using the Interim Federal Action Plan. Officials from the USDA Natural Resources Conservation Service told us they use the plan to determine conservation funding levels and priorities in the watershed. However, a former official who was responsible for CEQ’s Bay Delta portfolio said that although the plan still matches the needs of the watershed, agencies had stopped following it in the past several years because the plan had become less of a priority for the administration. In addition, EPA and NOAA officials stated they were not aware of agencies following the plan in the past several years. According to the plan, its most important aspect is the federal government’s reaffirmation of its partnership with state and local entities and its commitment to coordinate actions with them. Yet, of the 31 nonfederal entities responding to our survey questionnaire, 11 indicated that they were not at all familiar with the Interim Federal Action Plan, and another 9 indicated that they were slightly familiar with it. Further, according to Interior officials, although restoration efforts described in the Interim Federal Action Plan have largely remained the same and its functions and activities are still relevant, the plan is outdated. In particular, according to these officials, the Interim Federal Action Plan refers to the state’s 50-year conservation plan, which California is no longer pursuing. Moreover, according to Interior and EPA officials, the Federal Bay-Delta Leadership Committee—the coordinating body for the Interim Federal Action Plan—has not convened since the Delta Plan was developed in May 2013, even though the memorandum called for the committee to meet on a regular basis. Instead, according to Interior officials, the state-led Delta Plan Interagency Implementation Committee has replaced the federal leadership committee as the coordinating body for federal efforts in the watershed. Interior and EPA officials we interviewed said the federal role outlined in the Interim Federal Action Plan is no longer relevant because of recent leadership and strategic changes in the watershed resulting from the state’s withdrawal from the originally structured CALFED program and increased focus on the Delta through the Delta Stewardship Council. According to OMB staff and Interior and Delta Stewardship Council officials, the Delta Plan Interagency Implementation Committee is the current approach for coordinating among and between federal and state entities, and according to Interior officials, federal participation in the committee is key. The committee, however, focuses specifically on the Delta, and the Delta Plan generally does not include restoration efforts in the Bay and the upper watershed. Restoration requires a robust watershed-wide approach, according to the Interim Federal Action Plan, because the Bay, Delta, and upper watershed systems are interconnected. Specifically, according to one respondent to our survey, actions in the upper watershed affect water quality improvement and ecosystem restoration success in the Delta and ultimately the Bay. For example, according to California state officials, carefully timed water releases from dams in the upper watershed are the only way to control saltwater content in the Delta, which is critical for agriculture and urban water supply. Further, a National Research Council report states that Delta planning cannot be successful if it is not integrated into statewide planning because the Delta is fed by large upstream watersheds and water from the Delta is used outside the region, such as in the Bay. In addition, federal funding supports efforts throughout the watershed. While the Interim Federal Action Plan is consistent with several of our leading practices for collaboration, it is not being used by all federal agencies. As we reported in 2012, key considerations for implementing interagency collaborative mechanisms include whether participating agencies have clarified roles and responsibilities, developed ways to continually update and monitor written agreements on how agencies coordinate, and identified how leadership will be sustained over the long term. We have found that agencies that articulate their agreements in formal documents, such as plans, can strengthen their commitment to working collaboratively and that transitions and inconsistent leadership can weaken coordination. A written document can incorporate agreements reached among participants in any or all of the following areas: leadership, accountability, roles and responsibilities, and resources. Although the Interim Federal Action Plan reflects several of these practices, it is not being used to lead overall federal efforts and has not been updated to reflect current roles and responsibilities in the watershed, in particular the transition of coordination from the plan’s federal leadership committee to the Delta Plan Interagency Implementation Committee and the state’s increased focus on the Delta. Further, the Delta Plan Interagency Implementation Committee is not an interagency coordination mechanism for the federal and state agencies to communicate complete information for the entire watershed. Updating, including revising or refocusing, the Interim Federal Action Plan could help federal entities more fully coordinate with and support nonfederal restoration efforts across the watershed. EPA and Interior officials stated that coordination among the regions is challenging because agency missions and activities can be siloed. Officials from the Delta Stewardship Council told us that without coordinating with federal entities, they found it difficult to plan resources and work with federal entities. In addition, 31 of the 48 federal and nonfederal entities that responded to our survey questionnaire indicated that coordination of goals for the entire watershed was a very great or great challenge. Moreover, according to our analysis of questionnaire responses, 29 of 48 federal and nonfederal entities indicated that coordination among partners at different levels of government was a very great or great challenge. For example, in narrative responses to our survey questionnaire, one respondent stated that restoration projects can be delayed because many federal and nonfederal entities focus narrowly on their own missions without considering those of other stakeholders. By updating or revising the plan to outline and reflect entities’ roles and responsibilities in light of the changes in the state’s role and other relevant developments since 2009, and notifying all participating entities to ensure they are aware of the plan and their role in it, Interior and CEQ could help clarify the federal government’s role in supporting restoration efforts in the watershed and help ensure the effective use of federal resources in these efforts. Federal and nonfederal entities have developed measurable goals for comprehensive restoration efforts in the Bay and Delta and for specific restoration efforts in the upper watershed. Federal and nonfederal entities have also developed approaches to assess progress for restoration efforts in the Bay and Delta and for some goals in the upper watershed. In the Bay and Delta, the San Francisco Estuary Partnership uses indicators to rate the goals as good, fair, or poor, and in 2015, the partnership rated the overall state of the Delta as in fair to poor condition and the Bay as healthier. Federal and nonfederal entities have developed measurable goals for comprehensive restoration efforts in the Bay and Delta through the coordinating bodies for these areas and have developed measurable goals for specific restoration efforts in the upper watershed. The coordinating bodies have documented the goals in plans, which often contain action items aimed at achieving those goals. In addition, all three of the regions share some similar goals, such as ecosystem restoration, climate resilience, and water quality. Federal and nonfederal entities have developed measurable goals for comprehensive restoration efforts in the Bay through the San Francisco Estuary Partnership. The partnership documented these goals in the CCMP, which provides a 35-year vision for restoring the estuary. The most recent CCMP, updated in 2016, contains four long-term goals related to broad restoration efforts: ecosystem restoration, climate resilience, water quality and quantity, and governance. Each goal contains three objectives, which detail desired outcomes that make progress toward achieving goals. To achieve the goals and objectives, the plan also identifies 32 actions—each of which can be associated with multiple goals and objectives—that lay out 112 priority tasks for the next 5 years. Figure 6 shows an example of a priority task and how it relates to the actions, objectives, and goals. The 2016 CCMP also includes measurements to track progress for all actions and links the plan’s goals, objectives, and actions to 33 environmental indicators established by the partnership. Federal and nonfederal entities have developed measurable goals for comprehensive restoration efforts in the Delta through the Delta Stewardship Council and documented them in the Delta Plan, first published in 2013. The Delta Plan contains six goals and establishes funding principles to support implementation of the Delta Plan as a whole. Four of the goals—protecting, restoring, and enhancing the Delta ecosystem; reducing climate-related risks; improving water quality; and governance—are similar to those of the CCMP. To accomplish all six goals and meet the funding principles, the Delta Plan sets forth 87 provisions for various entities, such as local, state, and federal agencies. Fourteen of these provisions are legally enforceable regulatory policies. The Delta Plan also has 159 performance measures associated with these goals and provisions. For example, under improving water quality, the Delta Plan includes a provision related to priority habitat restoration areas. (See fig. 7.) Federal and nonfederal entities developed measurable goals for specific efforts in the upper watershed and documented these goals in plans specific to entities, projects, or restoration topics. These plans include goals similar to those outlined in the CCMP or the Delta Plan—such as ecosystem restoration, climate resilience, and improved water quality— and some of the goals have associated performance measures. For example, several federal and nonfederal entities documented in the Central Valley Joint Venture Implementation Plan the acreage they would like to enhance annually for conserving migratory bird habitat—a specific ecosystem restoration effort. Another group, California’s Central Valley Flood Protection Board, documented in the state’s Central Valley Flood Protection Plan that it would like to increase infrastructure performance in populous areas to result in a more resilient flood management system— an example of a specific resiliency goal. This goal contains tracking metrics, including measuring the miles of levees repaired or improved. In addition, Interior produces metrics and reports for activities under the Central Valley Project Improvement Act. Federal and nonfederal entities have developed indicators to assess and report progress toward some of the measurable goals in the Bay, and have applied these in the Delta as well. In the Bay, the San Francisco Bay Regional Water Quality Control Board has implemented regional monitoring pilot studies since 1989, and in 1992 it established a regional monitoring program led by a nonprofit science center. In 1991, in addition to water quality, the science center began reporting on the monitoring and assessment of ecosystem restoration and resilience in the estuary, such as changes over time in pollution, dredging, and numbers of endangered and threatened fish and wildlife. The San Francisco Estuary Partnership then used the science center’s restoration and resilience assessments to create the 1993 CCMP goals. At the same time, partly in response to a recommendation from the CCMP, the science center became the San Francisco Estuary Institute, a nonprofit scientific organization that performs monitoring to inform watershed management. The San Francisco Estuary Partnership began reporting on water quality progress in 2011. The first of these reports, titled the State of San Francisco Bay, focused on the Bay. In the Delta, the Delta Stewardship Council in 2013 began working to coordinate scientific monitoring efforts based on the goals outlined in the Delta Plan. Scientific monitoring efforts in the Delta include a regional water quality monitoring program, begun by the Central Valley Regional Water Quality Control Board in 2015. The monitoring efforts also include the Interagency Ecological Program, a consortium of state and federal agencies that have collaborated to monitor and research ecological conditions in the Delta since the 1970s, including by contributing to the CALFED science program. Based on the results of these separate monitoring efforts, the Delta Stewardship Council has a process in place to periodically update the Delta Plan’s performance measures and goals. In 2015, the San Francisco Estuary Partnership updated its assessment and report to include both the Bay and the Delta and renamed it State of the Estuary. The partnership plans to update these reports approximately every 5 years and include both the Bay and the Delta. For the 2015 report, more than 100 scientists from entities such as the San Francisco Estuary Institute, the U.S. Geological Survey, and the Delta Stewardship Council collaborated to monitor and assess estuary health against environmental indicators established by the partnership. The report includes 17 indicators specifically for the Bay, 8 indicators specifically for the Delta, and 4 estuary-wide indicators (see table 1). The report rates the status of the indicators—such as the safety of water for swimming, the safety of fish to eat, and the level of harbor seal populations—as good, fair, or poor. For example, the State of the Estuary report assessed the regional extent of tidal marsh in the Bay as “fair” and “improving” and the Yolo Floodplain Flows in the Delta as “poor;” however, the report did not detail the partnership’s methodology for delineating between “fair” and “poor” assessments. On the basis of its assessment, the partnership rated the Delta and Suisun Bay ecosystems as being in fair to poor condition and the Bay as healthier. In the upper watershed, progress assessment is tied to entity- and topic- specific plans and is not summarized by any one group or in one report. For example, California’s Central Valley Flood Protection Board assigns agencies to keep track of data toward tracking metrics for the goals of the Central Valley Flood Protection Plan. In another example, the state’s California EcoRestore initiative provides progress reports on restoration projects to mitigate damage caused by water conveyance programs. Information on the status of all restoration efforts across the watershed, including their accomplishments, is unknown because, while the information is being developed, complete and current information is not being fully collected or reported. Total expenditures for fiscal years 2007 through 2016 are unknown, in part because federal reports do not include complete or reliable data for federal and state expenditures in the watershed. Information on the status of all restoration efforts across the watershed, including their accomplishments, is unknown because complete and current information is not being fully collected or reported. At the state level, the San Francisco Estuary Institute and the Delta Stewardship Council each maintains a database with information about federal and nonfederal restoration efforts, including those implemented during fiscal years 2007 through 2016, but neither database contains data on all restoration efforts in the watershed. Specifically: EcoAltas. The San Francisco Estuary Institute, in cooperation with the San Francisco Bay Joint Venture, maintains the EcoAtlas database, which is the more comprehensive of the two databases. EcoAtlas integrates stream and wetland maps, restoration information, and monitoring results with land use, transportation, and other information important to the state’s wetlands. According to institute officials, the database was originally designed to focus on the Bay and includes information on nearly every restoration effort in the Bay. According to these officials, the institute is working to update EcoAtlas and gather information on all efforts across the watershed. Officials from several federal and nonfederal entities—including NOAA, the institute, the San Francisco Bay Joint Venture, and the Central Valley Joint Venture—told us that the completeness of EcoAtlas’s data on restoration efforts in the Delta is catching up to that for the Bay, but a lot of work remains to gather more complete data in the upper watershed, such as by gathering more complete project information from entities conducting restoration work there. DeltaView. The Delta Stewardship Council’s DeltaView database collects state and federal data on efforts directly related to implementing the state’s Delta Plan goals. As a result, DeltaView does not include information for all restoration efforts in the Delta since, for example, local government agencies and other nonfederal entities may also conduct restoration efforts in the Delta. According to its website, DeltaView is designed to track and report on Delta Plan progress and help the Delta Plan Interagency Implementation Committee make more informed decisions about implementing the Delta Plan. According to council officials, because it is designed to focus on the Delta, DeltaView does not include efforts in the Bay or upper watershed unless they directly affect the Delta. Further, while officials who manage EcoAtlas and DeltaView take steps to check the completeness of the data, such as using regional administrators to oversee project completeness for EcoAltas or following up with agency officials annually for DeltaView, they stated it is difficult to confirm their completeness because they largely rely on self-reporting by different federal and nonfederal entities. Council officials stated that while the information in EcoAtlas is generally more comprehensive, DeltaView’s information on restoration efforts in the Delta is more complete than EcoAtlas’s information about the Delta, and they are working with the institute on ways to merge the two databases to make more complete information available in a single database. On the federal level, section 105 of the CALFED Act requires Interior, in cooperation with the Governor of California, to submit a report annually to Congress that, among other things, describes the status of implementation of all CALFED components, such as water quality and ecosystem restoration across the watershed. Under the act, the report is to include the progress made in meeting certain goals as well as accomplishments in achieving certain CALFED objectives during the past fiscal year. However, according to Interior officials, the department issued the most recent of these reports in February 2009. Interior officials stated that the California Bay-Delta Authority used to collect information on all the projects in the watershed and prepare and submit these reports. However, since the California Bay-Delta Authority was abolished and replaced by the Delta Stewardship Council, Interior does not obtain this information from any state entity, although Interior is still required to submit the report annually to Congress. Because Interior has not issued a report since 2009, when the California Bay-Delta Authority was abolished, and because other sources of information on restoration efforts such as EcoAtlas are not yet fully developed, no complete or current information on the progress of restoration efforts is available. According to Interior officials, the requirement to report is outdated and the department does not have information to report because it stopped obtaining data from the California Bay-Delta Authority after it was abolished. However, Interior and other federal agencies continue to work with state agencies on the state’s current Delta Plan, which replaced the state’s CALFED plans. Also, according to Interior officials, the department has not reached out to the state to identify new sources of information, given the change in state plans or agency structure. Section 105 of the CALFED Act requires Interior, in consultation with California’s governor, to report annually on “the status of implementation of all components of the Calfed Bay-Delta Program.” The law goes on to identify the specific objectives on which Interior is to report, which include activities that Interior and other federal agencies are currently carrying out, such as research and wetland restoration. According to respondents to our survey questionnaire, having such information could help stakeholders make more informed decisions about these efforts. Specifically, according to our analysis of responses, 32 of 48 federal and nonfederal entities indicated that it would be very or extremely important to have reports on progress of federal and nonfederal entities in implementing restoration activities. In addition, according to our analysis of responses, 27 of 48 federal and nonfederal entities indicated that it would be very or extremely important to have reports on accomplishments of federal and nonfederal entities in achieving the objectives of restoration activities. Without attempting to obtain and report state information as required under section 105 of the CALFED Act, Interior will not have reasonable assurance that it is providing Congress, or others, with the information needed to monitor federal and nonfederal restoration activities. Total expenditures for all restoration efforts in the watershed for fiscal years 2007 through 2016 are unknown in part because federal reports do not include complete or reliable expenditure data, and other tracking mechanisms are still developing this information. San Francisco Estuary Institute officials stated that EcoAtlas recently began to include expenditure data for the on-the-ground costs of implementing restoration projects, but overall expenditure data on these projects are still incomplete. In addition, as discussed earlier, EcoAtlas is still in the process of gathering complete information for efforts in the Delta and upper watershed. DeltaView includes federal and state expenditure data for efforts in the Delta; however, according to Delta Stewardship Council officials, it does not include data for all restoration efforts in the Delta, such as those funded by nongovernmental organizations. The institute’s plans to expand EcoAtlas to include expenditures and data on efforts across the watershed, including by working with the council to merge the two databases, indicates that entities are taking steps to gather more complete information. As they continue to do so, more information will be available to report on expenditures for restoration efforts in the watershed. One source of information on federal and state expenditures across the watershed is OMB’s interagency budget crosscut reports for CALFED activities; however, these reports do not contain complete or accurate expenditure data. Section 106 of the CALFED Act requires OMB to submit a financial report annually to Congress, in coordination with the Governor of California and certified by the Secretary of the Interior, that includes, among other things, an interagency budget crosscut report. The report is to display each participating federal agency’s proposed budget for the upcoming fiscal year to carry out CALFED activities and identify all expenditures since 1998 by the federal and state governments to achieve the objectives of CALFED, which, as noted previously, include water quality and ecosystem restoration components. The report is also to contain a detailed accounting of all funds received and obligated by all federal and state agencies responsible for implementing CALFED activities during the past fiscal year. According to OMB staff, since California abolished the California Bay- Delta Authority in 2009, the state no longer submits state data for the crosscut report, so the agency only includes data reported by federal agencies in the crosscut reports and tables. OMB staff said this is because the state no longer has an agency organized around reporting this information. The Delta Stewardship Council has responsibility for the former state agency’s activities, but given its narrower focus on the Delta, it is unclear whether the council could submit data to OMB for the entire watershed. According to OMB staff, OMB has not asked the Delta Stewardship Council or any other state entities to submit the data they do have to OMB; however, a council official told us the council would like an opportunity to work on the crosscut report. Survey responses indicate that the state crosscut data could be helpful to federal and nonfederal entities. We asked survey respondents to indicate how important, if at all, they thought reports on all federal or state expenditures and funding committed to be spent (i.e., obligations) on restoration activities would be when they carry out activities related to these responsibilities in the San Francisco Bay Delta watershed. According to our analysis of survey responses, 24 of 48 federal and nonfederal entities indicated that it would be very or extremely important to have reports on both federal and state expenditures. Also, according to our analysis of survey responses, 27 of 48 federal and nonfederal entities indicated that it would be very or extremely important to have reports on federal obligations, and 24 of the 48 entities indicated that it would be very or extremely important to have reports on state obligations. Without attempting to obtain and report state information as required under section 106 of the CALFED Act, OMB will not have reasonable assurance that it is providing Congress with the information it needs to monitor federal and nonfederal restoration expenditures. In addition, while there was written guidance for submitting crosscut data for fiscal years 1998 through 2011, OMB has not updated its written guidance on reporting data for the CALFED Act since the guidance expired in 2011 to reflect who should report what data. Instead, according to OMB staff, it has generally provided oral instruction to agencies on what data to submit. As a result, we found that federal agencies reported different types of data for OMB to include in the budget crosscut and that the budget crosscut was therefore not reliable for the purposes of reviewing total expenditures. Some federal agencies, including EPA and the U.S. Geological Survey, note in their crosscut submissions that the data provided are funding levels or allocations, rather than expenditures. In addition, Interior reported that it submits obligations, which are also different than expenditures. As a result, the crosscut reports and tables may include a mix of federal budget authority, obligations, and expenditures, depending on the type of data the agencies choose to submit. According to OMB staff, while OMB reports federal budget authority data for the most recent fiscal year in the crosscut report, OMB relies on agencies to submit data on prior year expenditures for inclusion in the crosscut. However, the crosscut report itself labels the data reported as “enacted” dollars—or budget authority—but does not mention expenditures. Some federal officials said that clearer guidance would be helpful. For example, USDA officials stated that it would be helpful for OMB to clarify whether to submit estimated funding allocations or actual obligations and to provide more specific information about the types of restoration projects to include because the data USDA currently submits provide a narrow scope for the agency’s restoration-related work in the watershed. The lack of updated guidance is inconsistent with federal standards for internal control, which call for an agency to design control activities to achieve objectives and manage risks. Such control activities include clearly documenting internal controls, and the documentation may appear in management directives, administrative policies, or operating manuals. Because OMB has not updated its written guidance on reporting data since the guidance expired in 2011 to clearly communicate what data agencies should report, its mechanism for tracking data—the crosscut reports and tables—does not include complete or reliable expenditure data. As a result, congressional and other federal and nonfederal decision makers may not have the information they need to determine that resources are being used efficiently or effectively. For example, in a September 2017 report, Interior’s Office of Inspector General found that Reclamation obtained $50 million over 7 years for CALFED-related purposes using a process that it did not disclose to Congress through available mechanisms, including OMB’s crosscut reports. According to the Inspector General’s report, these crosscuts assist the President in considering the necessary and appropriate level of funding for each of the agencies in carrying out its responsibilities under CALFED. By directing its staff to update its written guidance for federal and state agencies on submitting data for its budget crosscut reports, OMB will have more reasonable assurance that it is helping those agencies provide current, complete, and accurate data to help congressional and other decision makers achieve restoration objectives. Several factors may limit restoration progress or pose risks to the long- term overall success of such efforts in the San Francisco Bay Delta watershed, according to our analysis of questionnaire responses from 48 federal and nonfederal entities. These factors reflect characteristics of watersheds in other parts of the country that we have previously discussed, including funding constraints and the effects of climate change (see fig. 8). Federal and nonfederal entities also identified up to three factors that pose the greatest risks to the long-term overall success of water quality improvement and ecosystem restoration efforts in the San Francisco Bay Delta watershed. Specifically, based on our analysis of the survey results, we found that federal and nonfederal entities consistently identified the following risks: Competing interests of water users, including residential, commercial, agricultural, and environmental. According to our analysis of survey responses, this particular risk varies by geographic area in the watershed. For example, 20 of 25 entities that indicated they conduct restoration work in the Sacramento River Watershed— part of the upper watershed region—identified this factor as a greatest risk. By comparison, 19 of 34 entities that indicated they conduct restoration work in the Bay identified this factor as a greatest risk. In its survey responses, one nonfederal entity indicated that the distribution of water and other natural resources among competing interests is not clearly defined or not distributed in a method that satisfies all parties. Therefore, according to this entity, stakeholders who are not satisfied with natural resources distribution may be hesitant to invest time and money in conservation practices that benefit water quality. In another survey response, a federal entity described competing interests as one of the biggest roadblocks in planning and implementing water quality improvement and ecosystem restoration in the Bay Delta region. This entity explained that there is an extremely limited freshwater supply in the region and interests that compete for it have resulted in several lawsuits and delays for restoration projects. Obtaining sufficient federal funding for water quality improvement and ecosystem restoration activities. Of the 48 survey respondents, 24 indicated that this factor is one of the greatest risks to long-term overall success of water quality improvement and ecosystem restoration efforts. According to one nonfederal entity’s survey response, funding for ecosystem restoration in the Bay area traditionally has come from a mix of federal and state sources. For example, the entity said a local source that will provide nearly $500 million over 20 years recently was established but needs to be leveraged by significant state and federal dollars to meet the estimated $1.5 billion needed for restoration in the Bay area. In its response to our survey, one federal entity stated that federal funding is extremely limited for restoration activities that are not part of mitigation efforts. The federal entity also stated that federal funding for long-term monitoring of restoration success and water quality improvement is difficult to sustain because these efforts are not eye- catching and do not provide quick results. A nonfederal entity stated that many state entities rely on federal grants to perform activities that result in improved water quality and ecosystem restoration. Planning for the effects of climate change. In their survey responses, 24 of 48 entities indicated that this factor is one of the greatest risks to long-term overall success of water quality improvement and ecosystem restoration efforts. One nonfederal entity said expected reductions in the Sierra Nevada snow pack—the largest source of water supply for the watershed—will result in increased demand on limited local water sources. Other respondents noted a need to consider addressing the effects of climate change at a high level. For instance, one nonfederal entity said successfully planning for climate change includes planning and coordinating at the watershed level, not at the project or jurisdictional level. Another nonfederal entity said the potential impact of sea level rise is great and ecosystem restoration solutions will require much more regional planning and agreement than more traditional engineering solutions. However, entities also acknowledged the challenges associated with planning for the effects of climate change with incomplete information. For example, in its response to our questionnaire, one entity stated it is difficult to understand the impact on water quality resulting from conservation practices on working lands, at both the private landowner level and the watershed level, if the projects have not incorporated climate change impacts such as flooding and sediment erosion. The factors identified by federal and nonfederal entities that may limit or pose a risk to restoration efforts are generally consistent with our prior work on large-scale ecosystem restoration efforts in other parts of the country (see Related GAO Products at the end of this report). For example, we previously reported that similar factors, such as funding constraints and the effects of climate change, may limit restoration efforts in the Great Lakes and Chesapeake Bay. Survey responses also indicate that some of these risks can be interrelated. For example, one federal entity said that while certain shoreline restoration and levee stabilization projects could ameliorate the effects of climate change, finding adequate funding to plan for and implement such projects is extremely difficult. According to this entity, all the competing interests and limited freshwater supply in the watershed further exacerbates these difficulties. In response to our questionnaire, federal and nonfederal entities identified what they consider to be the most important action that could be taken at a federal level to help improve restoration efforts in the watershed. For example, seven entities mentioned actions related to streamlining or coordinating federal permitting processes. Half of the entities that responded to our questionnaire also indicated a need for actions related to federal funding, and four entities indicated a need to use the best available science to direct restoration efforts. The complex nature of the restoration efforts in the San Francisco Bay Delta watershed demands a high level of coordination across a large number of entities and competing interests. The results of federal and nonfederal entities working together can be seen in parts of the watershed, such as the Bay, where this work has resulted in the development of comprehensive regional strategies, sources of funding for some restoration projects, an expanding regional database, and an inventory of potential projects. In other parts of the watershed, particularly the Delta, coordination has wavered. The CALFED Act was enacted in 2004 to implement, at the federal level, a federal-state partnership for restoring the San Francisco Bay Delta watershed. When the state of California withdrew from the originally structured CALFED federal-state partnership in 2009, the effort to coordinate across the entire watershed transitioned and the focus of coordination became the Delta Plan, a state-led effort. Key federal entities, including Interior and CEQ, continue to have interests across the watershed, such as coordinating or conducting programs and projects and expending resources. To that end, in 2009 they developed a unifying vision for the federal government through the Interim Federal Action Plan. However, as the state continues to change its focus within the watershed, the Interim Federal Action Plan has become outdated, and not all relevant federal entities are using it. By updating or revising the plan to outline and reflect entities’ roles and responsibilities in light of the changes in the state’s role and other relevant developments since 2009, and by notifying all participating entities to ensure they are aware of the plan and their role in it, Interior and CEQ could help clarify the federal government’s role in supporting restoration efforts in the watershed and help ensure the effective use of federal resources in these efforts. In addition, since California stopped participating in the originally structured CALFED partnership, information on projects and expenditures for restoration and other activities in the watershed have not been completely reported, or reported at all. Although California abolished the California Bay-Delta Authority, the requirements for Interior to report on the status of implementation of all CALFED components, including water quality and ecosystem restoration efforts, and for OMB to submit a financial report, including an interagency budget crosscut report, still exist, and information about related restoration efforts and expenditures remains unknown. By coordinating with the appropriate state entities to obtain and report the information available to meet the CALFED Act’s requirements, Interior and OMB would have more reasonable assurance that they are providing the information congressional and other decision makers need to monitor the restoration efforts and associated expenditures. Further, by directing staff to update OMB’s written guidance for federal and state agencies on submitting data for its budget crosscut reports, OMB would have more reasonable assurance that it is helping those agencies provide current, complete, and accurate data to help decision makers achieve restoration objectives. We are making seven recommendations—two each to Interior and CEQ to address issues with the Interim Federal Action Plan; one each to Interior and OMB to obtain and report information; and one to OMB to update its budget crosscut guidance. Specifically: The Secretary of the Interior should work with the Chair of CEQ to update or revise the Interim Federal Action Plan for the California Bay-Delta to outline and reflect entity roles and responsibilities in light of changes in the state of California’s role and other relevant developments since 2009. (Recommendation 1) The Secretary of the Interior should notify all participating entities to ensure they are aware of the Interim Federal Action Plan and their role in it. (Recommendation 2) The Chair of CEQ should work with the Secretary of the Interior to update or revise the Interim Federal Action Plan for the California Bay-Delta to outline and reflect entity roles and responsibilities in light of changes in the state of California’s role and other relevant developments since 2009. (Recommendation 3) The Chair of CEQ should notify all participating entities to ensure they are aware of the Interim Federal Action Plan and their role in it. (Recommendation 4) The Secretary of the Interior should coordinate with appropriate state entities to obtain and report the information available to meet the requirements under section 105 of the CALFED Act. (Recommendation 5) The Director of OMB should coordinate with appropriate state entities to obtain and report the information available to meet the requirements under section 106 of the CALFED Act. (Recommendation 6) The Director of OMB should direct staff to update OMB’s written guidance for federal and state agencies on submitting data for the budget crosscut reports OMB is required to submit under section 106 of the CALFED Act. (Recommendation 7) We provided a draft of this report for review and comment to CEQ, EPA, OMB, and the Departments of Agriculture, Commerce, Defense, and the Interior. We also provided the California Delta Stewardship Council a draft of this report for review and comment. Interior provided written comments and stated that it partially concurred with our three recommendations to the department; Interior also provided technical comments, which we incorporated into the report as appropriate. In an email from CEQ’s Deputy General Counsel, CEQ provided technical comments, which we incorporated into the report as appropriate, but the agency neither agreed nor disagreed with our recommendations to it. In oral comments provided on August 8, 2018, OMB neither agreed nor disagreed with our two recommendations to the agency, but OMB staff suggested some additional language to the recommendations. In addition, USDA and Commerce provided technical comments, which we incorporated into the report as appropriate. Defense and EPA informed us that they had no comments on the draft report. The California Delta Stewardship Council provided written comments stating that its staff generally agreed with the “sum” of the recommendations in the report. The council also provided technical comments, which we incorporated into the report as appropriate. In its written comments, reproduced in appendix IV, Interior stated that the department appreciated our review of the coordination of watershed restoration efforts among federal and nonfederal entities and that it partially concurred with our three recommendations to the department. Specifically, regarding our first two recommendations to update or revise the Interim Federal Action Plan and notify all participating entities of their role in the plan, Interior stated that the department believes revisiting the Interim Federal Action Plan is not the most efficient course of action because the state-led Delta Plan Interagency Implementation Committee now serves as the coordination group. Interior stated that it will continue to actively participate in the committee, which includes participation and leadership from federal agencies at the regional and Washington office levels. However, as we discuss in the report, the committee focuses on only one region of the watershed (the Delta), and federal agencies fund and carry out restoration efforts across all three regions of the watershed. Further, as we discuss in the report, the President’s fiscal year 2019 budget states that federal activities are coordinated through the Interim Federal Action Plan rather than the state-led committee. Also, Interior’s letter states that its bureaus are concurrently engaged with the state of California in multiple activities in the Bay Delta that span their respective mission areas. This provides further support for the plan to be updated or revised to include these types of activities. Thus, we continue to believe that Interior should update or revise the plan to better reflect changes in the state’s role and other relevant developments since 2009. Regarding our third recommendation to Interior that it coordinate with the state to meet reporting requirements, Interior stated that the California Delta Stewardship Council compiles and reports on funding information and progress for federal and state agencies and that Interior could coordinate with the state on information not reported by the council. As we discuss in the report, the council’s reporting efforts focus on only the Delta, although federal funding and efforts span the entire watershed; therefore, the council’s reporting efforts cannot fully address Interior’s reporting requirements. In addition, Interior has not reached out to state entities for this information since 2009, when the state agency from which Interior had previously obtained state data was abolished. Thus, we continue to believe that Interior should coordinate with the appropriate state entities to obtain and report the information available to meet the CALFED Act’s reporting requirements. We note that Interior said it would actively participate in the Delta Plan Interagency Implementation Committee and could seek to coordinate with the state on information not reported by the Delta Stewardship Council, and we are encouraged that the department recognizes the need to take these actions. In oral comments regarding our first recommendation to OMB that it coordinate with the state to meet reporting requirements, OMB staff said it is unclear whether the Director of OMB has the authority to require or compel the state or its agencies to provide data to OMB on restoration and other projects they are carrying out. The staff suggested that we revise the recommendation to state that the Director of OMB should “consider whether there are additional opportunities to” coordinate with appropriate state entities to obtain and report the available information. Our recommendation is for OMB to coordinate with appropriate state entities, not to require or compel them to do so. In addition, as stated in its written comments (reproduced in appendix V), the California Delta Stewardship Council—the state agency responsible for the activities of the abolished California Bay-Delta Authority—would welcome the opportunity to coordinate with OMB and contribute to the budget crosscut reports. Furthermore, Section 106 of the CALFED Act requires OMB to submit a financial report annually to Congress, in coordination with the Governor of California, that includes an interagency budget crosscut report. Thus, we believe that the recommendation is worded appropriately and captures the actions that OMB should take to coordinate with the appropriate state entities to obtain and report the information available to meet the CALFED Act's reporting requirements. In oral comments regarding our second recommendation to OMB that it update its written guidance for federal and state agencies on submitting data for the budget crosscut reports, OMB staff said that the agency does not have the expertise to validate or verify the quality of the information agencies submit and is not confident that the data collected will be reliable. The staff said that other entities with day-to-day experience with the programs and data and with the relevant statutory authority may be in a better position to obtain, report, and verify the quality of restoration data. The staff suggested that we revise the recommendation to state that the Director of OMB should “assess whether to” update OMB’s written guidance for federal and state agencies on submitting data for the budget crosscut reports. However, OMB’s current approach is resulting in the reporting of unreliable data. As reported above, OMB has generally provided oral instruction to agencies since its written guidance expired in 2011; as a result, the crosscut reports and tables may include a mix of federal budget authority, obligations, and expenditures. Further, Section 106 of the CALFED Act requires, among other things, that OMB identify all expenditures since 1998 by the federal and state governments to achieve CALFED objectives. Therefore, we continue to believe that OMB should update its written guidance to clarify the type of data that agencies should submit in order to ensure it is reporting the data required by the CALFED Act. We note that our recommendation does not direct OMB staff to validate or verify the quality of the information; instead, it states that OMB should clarify in guidance what data agencies should provide. In addition, if OMB determines it is appropriate, updated written guidance could advise agencies to validate and verify the data before submitting it to OMB. In its written comments, reproduced in appendix V, the California Delta Stewardship Council made four comments on the themes outlined in the recommendations of our report and two specific comments on the report’s description of the Delta. Commenting on the themes outlined in the recommendations, the council stated that: No entity in California has the sole responsibility or authority for managing water supply and the Delta ecosystem; instead, authority, expertise, and resources are spread out among a cadre of federal, state, and local agencies. The council further said that its Delta Plan Interagency Implementation Committee plays a vital coordination role for the 17 state and federal agencies operating in the Delta, that federal participation is critical to the committee’s success, and that it encourages federal agencies to continue to attend and actively participate in the committee. There is a history of coordination in the Bay Delta systems, as evidenced by events such as the State of the Estuary Conference and the Bay Delta Science Conference, as well as the CCMP. Given that the upper watershed currently lacks a collaborative structure such as the implementation committee, the council said that further exploration should be done as to how this gap could be filled. The council is not currently in contact with CEQ and OMB and would welcome the opportunity to coordinate with them should a revised Interim Federal Action Plan be pursued. The council also stated that, to the extent possible, such a revised plan should consider and build on existing planning frameworks such as the Delta Plan and the CCMP. As stated in the report, the council welcomes the opportunity to contribute to the CALFED budget crosscut reports. In addition, the council made two specific comments on the report’s description of the Delta. First, it stated that our report is thorough in discussing many aspects of the watershed, but it somewhat neglects the importance of levees, particularly in the Delta. While we provide an overview of levees in the background section, a more detailed discussion of these and other water infrastructure facilities is beyond the scope of this review, which is to examine restoration efforts in the watershed and does not include detailed examination of issues related to water supply. Second, the council stated that the report should mention and consider characteristics associated with the Delta as an evolving place, which refers to the council’s efforts to consider the interaction between environmental and social factors—such as cultural values and socio- economic issues—into decision making for the Delta. We believe our discussion of federal and nonfederal coordination roles within and across the watershed’s three major regions, including the Delta, appropriately considers the interaction between environmental and social factors, within the scope of this review. We are sending copies of this report to the appropriate congressional committees, the Chair of CEQ; the Secretaries of Agriculture, Commerce, Defense, and the Interior; the Administrator of EPA; the Director of OMB; the Executive Officer of the California Delta Stewardship Council; and other interested parties. In addition, the report is available at no charge on the GAO website at http://www.gao.gov. If you or your staff have any questions about this report, please contact me at (202) 512-3841 or gomezj@gao.gov. Contact points for our Offices of Congressional Relations and Public Affairs may be found on the last page of this report. GAO staff who made key contributions to this report are listed in appendix VI. Many federal and nonfederal entities, including state and local government agencies and nongovernmental organizations, have roles related to water quality improvement and ecosystem restoration efforts in the San Francisco Bay Delta watershed. Different combinations of federal and nonfederal entities work throughout the watershed and its three major geographic areas, which are the San Francisco Bay and its local watershed (Bay), the Sacramento-San Joaquin Delta (Delta), and the upper watershed, which includes California’s Central Valley and the western slope of the Sierra Nevada Mountains. See below for a list of federal and nonfederal entities and a brief description of some of their restoration-related roles in the watershed. We selected these entities based on our review of documents provided by, and interviews with, federal and nonfederal entities. Several federal entities have roles related to water quality improvement and ecosystem restoration efforts in the watershed. All federal agencies listed are signatories to the 2009 memorandum of understanding, unless otherwise noted. Federal agencies and some of their restoration-related roles include the following: Executive Office of the President. Council on Environmental Quality (CEQ). Under the 2009 memorandum of understanding, CEQ is to work with the Secretary of the Interior in coordinating the development and implementation of federal policy and initiatives in Bay-Delta matters and is the co- chair of the Federal Bay-Delta Leadership Committee. Office of Management and Budget (OMB). OMB is not a signatory to the 2009 memorandum of understanding, but under the Calfed Bay-Delta Authorization Act (CALFED Act), OMB is required to annually submit a financial report to Congress, in coordination with the Governor of California and certified by the Secretary of the Interior, that includes, among other things, an interagency budget crosscut report that identifies all expenditures since 1998 by the federal and state governments to achieve the objectives of the Calfed Bay-Delta Program (CALFED). CALFED program components include, among other things, water quality and ecosystem restoration. U.S. Army Corps of Engineers. According to Corps officials, the Corps plans and implements projects, including ecosystem restoration projects; participates in regional planning, while using its own return- on-investment analysis for prioritizing projects; and helps the state water agencies maintain levees. The Corps also issues permits for the discharge of dredged or fill material under section 404 of the Clean Water Act. U.S. Department of Agriculture (USDA). Natural Resources Conservation Service (NRCS). Through general conservation programs and also its targeted Bay Delta Initiative, NRCS and its local partners aim to address the critical water quantity, water quality, and habitat restoration needs of the Bay Delta region by implementing voluntary conservation practices on private lands. NRCS provides agricultural producers technical and financial assistance in the Bay Delta region to implement conservation practices and establish conservation easements that improve water quality and quantity and restore and protect wetland, riparian, and wet meadow habitat. U.S. Forest Service. The Pacific Southwest Region of the U.S. Forest Service manages 20 million acres of National Forest land in California. National forests supply 50 percent of the water in California and form the watershed of most major aqueducts and more than 2,400 reservoirs throughout the state. According to U.S. Forest Service officials, the agency’s management actions on National Forest land in California are focused on ecological restoration, with the goal of retaining and restoring the ecological resilience, including water quality, of terrestrial and aquatic ecosystems. According to these officials, this work is often accomplished using an “all lands” approach to restoration, by coordinating and collaborating across forests and wildlands regardless of ownership. Ecological restoration management actions that contribute to water quality include meadow, river, and riparian restoration to improve watershed function, as well as fuels reduction activities, such as forest thinning and prescribed fire. According to these officials, many forest lands have dense fuels and are highly susceptible to severe wildfire, which causes increased erosion rates and sedimentation and negatively affects water quality and delivery. U.S. Department of Commerce. National Oceanic and Atmospheric Administration (NOAA). NOAA implements the Endangered Species Act for certain species. Under section 7 of the act, federal agencies must ensure that any action they authorize, fund, or carry out is not likely to jeopardize the continued existence of any endangered or threatened species or result in the destruction or adverse modification of its critical habitat. To fulfill this responsibility, federal agencies must consult with NOAA’s National Marine Fisheries Service, depending on the affected species, to assess the potential effects of proposed actions. Formal consultations between federal agencies and the National Marine Fisheries Service or U.S. Fish and Wildlife Service are required where a proposed action could have an adverse effect on listed species or designated critical habitat; these consultations conclude with issuance of biological opinions by the National Marine Fisheries Service or U.S. Fish and Wildlife Service. NOAA also obtains, manages, and expends funding to conduct habitat restoration. According to NOAA officials, NOAA’s Restoration Center has directed federal funds toward restoration projects in the Bay Delta. In addition, funds from natural resource damage assessments have been used for habitat restoration in San Francisco Bay, according to NOAA officials. U.S. Department of the Interior. Under the 2009 memorandum of understanding, Interior is to serve as the lead for developing and coordinating federal policy and initiatives in Bay-Delta matters and is the co-chair of the Federal Bay-Delta Leadership Committee. Under the CALFED Act, Interior is required to annually submit a report to Congress, in cooperation with the Governor of California, that, among other things, describes the status of implementation of all CALFED components, which include water quality and ecosystem restoration components. Bureau of Reclamation. Reclamation administers the Central Valley Project, which has long-term contracts to supply water to more than 250 contractors in 29 of California’s 58 counties, and implements a number of actions under the Central Valley Project Improvement Act. The act was enacted for several purposes, including to protect, restore, and enhance fish, wildlife, and associated habitats. Reclamation also implements other actions, such as those under the San Joaquin River Restoration Settlement Act. U.S. Fish and Wildlife Service. The U.S. Fish and Wildlife Service implements the Endangered Species Act for certain species. According to agency officials, the U.S. Fish and Wildlife Service is also a major landowner, with several National Wildlife Refuges throughout the watershed where restoration efforts are implemented. Additionally, according to agency officials, the U.S. Fish and Wildlife Service provides funding through grant programs, such as the North American Wetlands Conservation, National Coastal Wetlands Conservation, and Wildlife and Sportfish Restoration programs, and provides technical assistance through efforts, such as the Partner for Fish and Wildlife, Coastal, and Tribal Wildlife programs. U.S. Geological Survey. According to U.S. Geological Survey officials, the agency’s role in the watershed includes conducting physical, chemical, and biological monitoring and scientific investigations to support water and water quality management, fish and wildlife management, and infrastructure management and protection. According to officials, the agency also provides policy- neutral technical support to Interior and other federal, state, and local entities. U.S. Environmental Protection Agency (EPA). EPA implements the Clean Water Act, including management of the National Estuary Program. According to agency officials, EPA also provides authorization, financial support, and oversight of the California State Water Resources Control Board, the partner state agency charged with implementing Clean Water Act programs in California, and provides direct funding, technical assistance, and oversight of programs and projects achieving Clean Water Act goals in the state. Several state government entities in California have roles related to water quality improvement and ecosystem restoration efforts in the watershed. A list of selected state agencies and information from the agencies summarizing their restoration-related roles follows: California Delta Stewardship Council. The Delta Stewardship Council is a planning and science agency, with some regulatory authority. The council develops and reviews the Delta Plan, the implementation of which is to further the restoration of the Delta ecosystem and a reliable water supply. The council also funds research, synthesizes and communicates scientific information to decision makers, and coordinates with Delta agencies to promote science-based adaptive management. In addition, the council establishes and oversees the Delta Plan Interagency Implementation Committee, a joint state-federal committee that implements the Delta Plan. California Natural Resources Agency. The Natural Resources Agency is a resource management agency, with some regulatory authority. Central Valley Flood Protection Board. The Central Valley Flood Protection Board establishes and enforces standards for the maintenance and operation of the flood control system; develops and implements the state’s flood protection plan for the Central Valley; and coordinates activities among the Corps and local flood control agencies. Department of Fish and Wildlife. The Department of Fish and Wildlife plans, collaborates on, enforces, and funds species management, habitat conservation, and wetlands restoration. According to agency officials, the department also is a major owner of land where restoration efforts take place, such as the Napa-Sonoma Marsh Wildlife Area and Eden Landing Ecological Reserve, and houses the California Wildlife Conservation Board, which provides funding for restoration projects. Department of Water Resources. The Department of Water Resources administers the California State Water Project, including sales to water contractors. The department also implements and funds—through the State Water Project—two fish habitat restoration projects in response to NOAA and U.S. Fish and Wildlife Service biological opinions. In addition, the department develops the California Water Plan, the state’s overall water resources plan. Sacramento-San Joaquin Delta Conservancy. The Sacramento- San Joaquin Delta Conservancy plans, collaborates on (with local communities), implements, and funds projects in the Delta and Suisun Marsh to protect, improve, and restore habitats and ecosystems, improve water quality, and support water-related agricultural sustainability, among other things. San Francisco Bay Conservation and Development Commission. The San Francisco Bay Conservation and Development Commission plans, collaborates on, and regulates the San Francisco Bay, Bay shoreline, and Suisun Marsh; it also permits projects that fill or extract materials from the Bay. Sierra Nevada Conservancy. The Sierra Nevada Conservancy plans, collaborates on, implements, and funds projects in parts of the upper watershed to protect, improve, and restore habitats and ecosystems, improve water quality, and prepare for climate change, among other things. State Coastal Conservancy. The State Coastal Conservancy plans, collaborates on, implements, and funds—partly through voter-approved bonds—projects around the Bay to protect and improve natural lands, improve water quality and wildlife habitats, and prepare for climate change, among other things. California Environmental Protection Agency. The California Environmental Protection Agency is a regulatory agency. State Water Resources Control Board. The State Water Resources Control Board allocates water rights, adjudicates water rights disputes, develops statewide protection plans, establishes water quality standards, and guides the nine regional water quality control boards. San Francisco Bay Regional Water Quality Control Board. One of nine regional water quality control boards in California, the San Francisco Bay Regional Water Quality Control Board exercises rulemaking and regulatory activities for the Bay. Central Valley Regional Water Quality Control Board. One of nine regional water quality control boards in California, the Central Valley Regional Water Quality Control Board exercises rulemaking and regulatory activities for the Central Valley (including the Delta) of the upper watershed. Other nonfederal entities—including local and regional government agencies, nongovernmental organizations, private businesses, and private landowners—have roles related to water quality improvement and ecosystem restoration efforts in the watershed. Other nonfederal entities and some of their restoration-related roles include the following: Central Valley Joint Venture. The Central Valley Joint Venture is a cooperative, regional partnership—partially supported through the U.S. Fish and Wildlife Service and established under the North American Waterfowl Management Plan—that plans and coordinates migratory bird and other habitat restoration and conservation in the Central Valley. San Francisco Estuary Institute. The San Francisco Estuary Institute is a nonprofit science center that provides data and other technical tools for assessing the health of the waters, wetlands, wildlife, and landscapes of the Bay and Delta; manages the EcoAtlas database of restoration projects; and works closely with the California State Water Resources Control Board and the San Francisco Estuary Partnership. San Francisco Estuary Partnership. The San Francisco Estuary Partnership is a cooperative, regional partnership that develops and manages the comprehensive conservation and management plan for the San Francisco Estuary (i.e., the Bay Delta) under EPA’s National Estuary Program, including coordinating projects and leveraging funds. The partnership is staffed by the nine-county Association of Bay Area Governments and housed by the San Francisco Bay Regional Water Quality Control Board. San Francisco Bay Joint Venture. The San Francisco Bay Joint Venture is a cooperative, regional partnership—organized through the U.S. Fish and Wildlife Service and established under the North American Waterfowl Management Plan—that plans and coordinates migratory bird and other habitat restoration and conservation in the Bay. Other regional government agencies. Other regional government agencies have a variety of restoration-related roles, depending on the entity. In addition to the San Francisco Estuary Partnership, examples of regional government agencies with restoration roles in the watershed include the Bay Area Clean Water Agencies, Bay Area Flood Protection Agencies Association, and California Association of Resource Conservation Districts. Nongovernmental organizations. Other nongovernmental organizations have restoration-related roles in the watershed, including the Audubon Society, Bay Planning Coalition, Ducks Unlimited, Nature Conservancy, and Save the Bay. Local governments. Local governments have a variety of restoration-related roles, depending on the entity. For example, according to U.S. Fish and Wildlife officials, Marin and San Mateo Counties are recognized leaders in planning for climate resiliency in wetland restoration. Also, Alameda County uses sediment excavated from flood control district channels to build or create wetlands to provide vital wildlife habitat. In addition, water treatment facilities work with the California State Water Resources Control Board to help fund the San Francisco Estuary Institute’s water quality monitoring program. Dredging businesses. Dredging businesses work with the California State Water Resources Control Board to help fund the San Francisco Estuary Institute’s water quality monitoring program. Water contractors. Through obligations under the Central Valley Project and State Water Project, water contractors help fund certain restoration projects required under biological opinions by various regulatory agencies, including NOAA, the U.S. Fish and Wildlife Service, and the California Department of Fish and Wildlife, according to state officials. Private landowners. Some private landowners collaborate on or sell land for various restoration and conservation projects. Private landowners include businesses (e.g., technology companies and an industrial salt pond owner) and farmers in the Bay and farmers and ranchers throughout the Delta and upper watershed. In this report, we examine (1) the extent to which federal and nonfederal entities coordinate their San Francisco Bay Delta watershed restoration efforts, (2) the extent to which federal and nonfederal entities have developed measurable goals and approaches to assess progress for San Francisco Bay Delta watershed restoration efforts, (3) information on the status of San Francisco Bay Delta watershed restoration efforts and related expenditures for fiscal years 2007 through 2016, and (4) key factors that may limit San Francisco Bay Delta watershed restoration, according to federal and nonfederal entities. To address all four objectives, we reviewed relevant federal and state laws and documents. We also interviewed officials from more than 28 federal, state, and other entities we identified through our review of laws and documents, snowball sampling, and their participation in regional interagency groups conducting restoration work in the San Francisco Bay Delta watershed. During these interviews, we asked about, among other things, restoration plans that coordinate multiple aspects of water quality improvement and ecosystem restoration efforts on a regional level in the San Francisco Bay Delta watershed. Officials and representatives we interviewed identified the Comprehensive Conservation and Management Plan (CCMP) and the Delta Plan as the overarching regional strategies for the Bay and Delta, respectively. We considered these strategies “comprehensive regional plans” and reviewed them to address our objectives. To address our objectives, we obtained information from a questionnaire we sent to all 61 federal, state, and other entities that serve on the boards or implementation committees of regional interagency groups conducting restoration work in our geographic scope. These groups were the San Francisco Bay Joint Venture, San Francisco Estuary Partnership, Delta Plan Interagency Implementation Committee, and Central Valley Joint Venture. The survey group includes many of the entities listed above in appendix I. We also sent this questionnaire to federal agencies that are signatories of the CALFED record of decision and 4 other relevant organizations identified through snowball sampling. We initially identified and distributed our questionnaire to 78 entities. We sent a single questionnaire to each nonfederal entity (e.g., state agency, nongovernmental organization, local government agency, etc.) and sent more than one questionnaire, as appropriate, to federal agencies that have offices or officials working in different parts of the watershed. We determined which federal level to survey based on a review of agency organizational charts and inquiries with agency officials. We considered each office or federal designee to be a separate federal entity due to the distinct nature of their work based on geographic region. To ensure we got survey responses that reflect the opinions of an entity, we included instructions for survey points of contact to collaborate with colleagues, as needed, and indicated that we only wanted one survey response from each entity. After we began our survey effort, we identified 6 entities as out of scope for a variety of reasons, such as being a subgroup of another entity we surveyed. Our final population of surveyed entities was 72, of which 48 responded to our questionnaire, a response rate of 67 percent. In our questionnaire, we collected information on water quality improvement and ecosystem restoration efforts in the San Francisco Bay Delta watershed, including, among other things, (1) challenges that may limit restoration progress; (2) risks to the long-term overall success of water quality improvement and ecosystem restoration efforts; and (3) types of reports that entities could consider important when carrying out responsibilities related to water quality improvement and ecosystem restoration. To ensure that our survey questions were appropriate and that respondents could answer them in a reliable and meaningful way, we conducted survey pre-tests with 5 entities from the study population, had the questionnaire reviewed by an independent reviewer within GAO, and revised the questionnaire as appropriate based on the results of these efforts. The survey questionnaire used for this review is in appendix III. Our survey field period ran from December 4, 2017, through January 29, 2018. We distributed the questionnaire electronically through email. After the requested return date passed, we emailed or telephoned respondents who had not returned the questionnaire and asked them to respond. By January 29, 2018, we received 48 questionnaires. In order to minimize potential nonresponse bias, we reviewed the key characteristics of respondents to ensure we received completed questionnaires from each of our population subgroups. Because this was not a sample questionnaire, it has no sampling errors. However, the practical difficulties of conducting any survey may introduce nonsampling errors, such as difficulties in interpreting a particular question or sources of information available to respondents, which can introduce unwanted variability into the survey results. We took steps in developing the questionnaire, collecting the data, and analyzing them to minimize such nonsampling error. Survey questionnaires may also be subject to error in entering and analyzing data. We implemented quality control procedures on our data entry by verifying the accuracy of the process. We noted any missing, irregular, or incorrect responses by the respondent and resolved these responses, as needed, through email correspondence with the relevant entities. To examine the extent to which federal and nonfederal entities coordinate their San Francisco Bay Delta watershed restoration efforts, we interviewed officials from federal, state, and other entities to identify key regional plans and coordination efforts. We reviewed these plans and efforts and compared federal coordination efforts against a selection of our leading practices for collaboration to assess the extent to which federal entities followed these practices. The selected leading practices for collaboration include whether participating agencies have clarified roles and responsibilities, developed ways to continually update and monitor written agreements on how agencies coordinate, and identified how leadership will be sustained over the long-term. Our questionnaire discussed above also surveyed entities to identify coordination-related challenges, if any. To understand what restoration projects were being carried out, we obtained information from the San Francisco Estuary Institute’s EcoAtlas database and the Delta Stewardship Council’s DeltaView database on restoration projects. We also conducted site visits to a nonprobability sample of four projects selected to provide illustrative examples of a variety of restoration activities in different locations in the watershed. We identified these sites by asking knowledgeable stakeholders about restoration projects in each region of the watershed that involved a variety of partners, including federal agencies, that were at various stages of completion. We then arranged visits that would allow us to observe projects in each region that illustrated a range of these selection criteria. We also conducted site visits to water project facilities, including a reservoir, dam, and pumping station. In addition, we attended the State of the San Francisco Estuary Conference in Oakland, California, on October 10 and 11, 2017, and observed many presentations and panel discussions on topics ranging from Delta restoration planning to pesticides in the estuary, by a wide range of officials from federal and nonfederal entities conducting restoration efforts across the watershed. To examine the extent to which federal and nonfederal entities have developed measurable goals and approaches to assess progress for San Francisco Bay Delta watershed restoration efforts, we reviewed comprehensive regional plans and related goals and progress reports, including the technical appendix for the State of the Estuary report. To do so, we looked for factors such as goals with quantifiable metrics and targets, as well as indicators used to assess and report progress. We also interviewed officials from federal, state, and other entities, including scientific groups, about efforts to develop measurable goals and assess restoration progress. To examine information on the status of San Francisco Bay Delta watershed restoration efforts and related expenditures for fiscal years 2007 through 2016, we obtained and analyzed available data—collected from the EcoAtlas and DeltaView databases—that included information about projects, expenditures, and cost estimates for this period. This period covers the time before and after the state withdrew from the CALFED federal-state partnership, as originally structured, and includes the last full fiscal year for which the most recent data were available at the time of our review. We assessed the reliability of these data by interviewing knowledgeable officials and reviewing database documentation and determined that they were not reliable for purposes of identifying all restoration projects across the entire watershed and for reporting related expenditure data. We also reviewed federal and state reports on budget requests and authority for that period and interviewed officials from federal, state, and other entities about available sources of data on projects, expenditures, and cost estimates. We also obtained and reviewed OMB’s Bay Delta budget crosscuts, which include financial information for San Francisco Bay Delta watershed restoration efforts reported by federal and state agencies, for fiscal years 2007 through 2019. We assessed the reliability of the data in the federal budget crosscut reports and tables by interviewing federal agency officials about what data they provided for the reports and tables and analyzing the data provided in the crosscut reports. We determined that the data were reliable only to report examples of the magnitude of funding for individual agencies. We determined that these data were not reliable to aggregate funding levels across programs and agencies or to compare funding levels of the various agencies, as we discuss in this report. We then compared OMB’s written guidance on submitting data for the crosscut reports with federal standards for internal control to assess the extent to which federal agencies followed the standard for design of control activities. To determine key factors that may limit San Francisco Bay Delta watershed restoration, according to federal and nonfederal entities, we sent the survey questionnaire described above to federal, state, and other entities to obtain views on (1) challenges that may limit restoration progress and (2) risks to the long-term overall success of water quality improvement and ecosystem restoration efforts. We also interviewed officials from federal, state, and other entities about factors that may limit restoration progress, as well as reviewed progress reports and studies exploring these factors. We conducted this performance audit from April 2017 to August 2018 in accordance with generally accepted government auditing standards. Those standards require that we plan and perform the audit to obtain sufficient, appropriate evidence to provide a reasonable basis for our findings and conclusions based on our audit objectives. We believe that the evidence obtained provides a reasonable basis for our findings and conclusions based on our audit objectives.

Summary: The San Francisco Bay Delta watershed—which drains a vast area of California from the Sierra Nevada Mountains to the Pacific Ocean—supplies drinking water for 25 million people and provides irrigation for about half the nation's fruit and vegetable production. Decades of development and agriculture have led to large reductions in water quality and supply, natural flood protection, and habitats across the watershed's three major regions: the Bay, the Delta, and the upper watershed. Federal entities have been working with nonfederal entities for decades to protect and restore the watershed. GAO was asked to review restoration efforts in the watershed. This report examines, among other objectives, (1) the extent to which federal and nonfederal entities coordinate watershed restoration efforts and (2) information on the status of these efforts and related expenditures for fiscal years 2007 through 2016, the most recent data available. GAO reviewed laws; regional databases, plans, and reports; and budget documents. It also surveyed the 72 members of interagency groups (48 responded) and interviewed federal and nonfederal officials. Federal entities, including the Department of the Interior, and nonfederal entities, such as California state agencies and nonprofits, carry out and coordinate a wide range of restoration efforts in the San Francisco Bay Delta watershed. These efforts have multiple benefits, such as improved water quality and habitat in restored marshland (see fig. below). The entities coordinate comprehensive efforts in the San Francisco Bay area (Bay) and Sacramento-San Joaquin Delta (Delta) through two groups. Federal efforts across the watershed are to be led and coordinated by Interior and the Council on Environmental Quality (CEQ) through a 2009 Interim Federal Action Plan, but not all federal entities are using the plan. Interior officials said the plan is no longer relevant because state and federal roles have changed. For example, they said a state-led committee acts as the coordinating body for federal entities; however, this committee focuses on one region of the watershed, while federal funding supports efforts in all three regions. By updating or revising the Interim Action Plan, Interior and CEQ could help clarify federal roles in supporting restoration efforts in the watershed. Information on the status of all restoration efforts across the watershed, including their accomplishments, is unknown because information is not being fully collected or reported. Also, related expenditures for fiscal years 2007 through 2016 are unknown, in part because federal reports do not include complete or reliable data for restoration efforts in the watershed. The 2004 CALFED Bay-Delta Authorization Act requires Interior and the Office of Management and Budget (OMB) to report annually to Congress on restoration accomplishments and federal and state expenditures in the watershed, respectively. Interior has not issued these reports since 2009, when the state agency from which Interior had obtained the state data was abolished. OMB has issued its reports with federal, but not state, data for the same reason. However, Interior and OMB have not reached out to other state entities for this information. Without obtaining and reporting available information, as required by law, Interior and OMB will not have reasonable assurance that they are providing Congress with the information needed to monitor federal and nonfederal restoration efforts and expenditures. GAO made seven recommendations, including that Interior and CEQ update or revise the Interim Federal Action Plan and that Interior and OMB coordinate with the state to meet the CALFED Act's reporting requirements. Interior partially concurred with the recommendations, and CEQ and OMB neither agreed nor disagreed with them. GAO maintains its recommendations are valid.
