  The Bay Institute's primer Gone with the Flow describes in plain language how runoff flowing from the mountain watersheds ringing California’s Central Valley provided coldwater paradises for salmon returning to their native streams; turned lowland rivers and their floodplains into a rich source of food and shelter for young fish; mingled in the Delta’s complex maze of marshes and sloughs; and created a vast expanse of brackish water habitat essential for estuarine creatures in the upper reaches of San Francisco Bay.

  The primer also explains how the lack of access to most upland streams now forces migratory fish to cope with undesirable, often lethal flow conditions; how runoff in lowland rivers has been shifted from spring to summer, or even almost completely cut off in the San Joaquin basin, with disastrous consequences for the environment; how reverse flows in Delta channels kill hundreds of millions of aquatic organisms each year; and how the Bay is now in a permanent ecological drought because of the diversion of half its freshwater inflow.

  Status and Trends of Delta-Suisun Services

  Department of Water Resources | March 1, 2007...

  Covering only about 1 percent of California’s area, the Sacramento-San Joaquin Delta, including Suisun Bay and Marsh (hereafter referred to as Delta-Suisun), contributes much more to the state and nation than one might expect from its small size.

  The Delta-Suisun provides a set of environmental and economic services whose benefits extend well beyond its borders. To help people gain a common understanding of these services, this report provides an overview of the existing status of these services and a perspective about how these services may change in the future.

  This report was prepared to highlight observations and to present a common understanding about the status and trends of key Delta-Suisun services. The Delta Risk Management Strategy (DRMS) is considering these observations while conducting a risk assessment for the Delta-Suisun and will report on its findings in spring 2007.

  Having a common understanding of the area’s services will benefit ongoing and new Delta-Suisun studies and initiatives. Information in this report will be considered by members of the Delta Vision Blue Ribbon Task Force and Stakeholder Coordination Group as they begin work on the Delta Vision and Strategic Plan.

  Cal-EPA was created to consolidate environmental programs and concentrate on vigorous enforcement of environmental regulations. The report discusses risk assessment activities, uniform permit processes, public involvement, and the advantages and consequences of bringing all environmental entities into Cal-EPA. In addition, the Commission addresses the short- and long-term costs and savings. The Cal-EPA report has seven findings and seven recommendations.

  Adaptive Management for Ecosystem Restoration: Analysis and Issues for Congress

  Adaptive Management for Ecosystem Restoration: Analysis and Issues for Congress

  Congressional Research Service | March 4, 2011...

  Summary

  Adaptive management is the process of incorporating new scientific and programmatic information into the implementation of a project or plan to ensure that...

  Adaptive management is the process of incorporating new scientific and programmatic information into the implementation of a project or plan to ensure that the goals of the activity are being reached efficiently. It promotes flexible decision-making to modify existing activities or create new activities if new circumstances arise (e.g., new scientific information) or if projects are not meeting their goals.

  The complex and dynamic nature of ecosystems make their restoration and management amenable to an adaptive management approach, and the concept is being implemented at scales that include entire regions or river basins. Adaptive management has been used to guide several major ecosystem restoration efforts with involvement by the federal  government, including those on the Colorado and Platte rivers. Some of these adaptive management efforts have been specifically authorized by Congress, whereas other efforts have been formulated by agencies.

  Adaptive management has also been proposed as a guiding principle for several new and ongoing major restoration efforts, including those in the Chesapeake Bay and Lake Tahoe.

  The concept of adaptive management is straightforward, but its implementation can be difficult. A preliminary review of federal adaptive management efforts related to ecosystem restoration projects suggests that governance structures, management protocol and other factors vary widely.  Additionally, the scope and timing of efforts employing the term “adaptive management” seems  to vary among these projects. Where adaptive management has been implemented, it has encountered challenges. While adaptive management theoretically uses the best available science and monitoring to guide a project or program towards its stated goals, in practice the process can be affected by a number of outside factors.

  As the number of federal adaptive management efforts grows, Congress may revisit its role in shaping adaptive management programs in legislation. Some argue that Congress should do more to provide specific direction for major adaptive management initiatives in order to make adaptive management more consistent among these efforts. Others contend that Congress should allow federal agencies or restoration governing bodies to shape their own adaptive management programs, thus providing them with flexibility to match their program to their restoration needs.

  In addressing adaptive management, Congress may face decisions regarding the implementation guidelines and authorizations it provides these efforts, funds to establish and carry out these programs, and oversight issues.

  This report provides an introduction to the concept of adaptive management. It focuses on the application of this concept to large, freshwater aquatic ecosystem restoration projects with multiple stakeholders. A summary of the benefits and drawbacks of adaptive management for these projects is provided, along with analysis of potential issues associated with various governance models for these efforts. The potential role for Congress in addressing adaptive management is also discussed. As an appendix, the report summarizes the structure and implementation of federal adaptive management efforts to date five ecosystems: Glen Canyon/Colorado River, Platte River, Lower Colorado River, Missouri River, and Florida Everglades.
