This appendix describes the existing conditions for the targets of the Central Valley Flood Protection Plan (CVFPP) Conservation Strategy (Conservation Strategy). It describes these existing conditions for the same geographic units used in the objectives of the Conservation Strategy: conservation planning areas (CPAs) and landscape units within CPAs. 

CVFPP Conservation Strategy Appendix G. Identification of Target Species and Focused Conservation Plans

 The purpose of the Conservation Strategy of the Central Valley Flood Protection Plan (CVFPP) is to provide direction for the California Department of Water Resources’ (DWR’s) environmental stewardship activities related to integrated flood management in the Central Valley, and to provide a framework and support for programmatic permitting of flood management activities.  One goal of the Conservation Strategy is to contribute to the recovery and stability of native species populations and overall biotic community diversity. A set of potential target species was identified to support measurable objectives for this goal. For those target species with the greatest need for recovery of their populations, focused conservation planning was conducted. This appendix documents the process used for selecting the target species of the Conservation Strategy, including 17 target species for which focused conservation planning was conducted. The results of this focused planning are also provided in this appendix, in the form of focused conservation plans. This document is scheduled to be updated every 5 years.   Because the conservation needs of species change, in the future, additional species may become suitable targets for the Conservation Strategy. Therefore, during preparation of the 5-year updates to the CVFPP, the preliminary list of species in this appendix will be reevaluated using the same criteria described below. Species meeting these criteria will be added, and focused conservation plans will be developed for them and included in subsequent updates of the Conservation Strategy. During the public comment period, new information regarding the status of the delta smelt (Hypomesus transpacificus) and its habitat use in the Systemwide Planning Area (SPA) was made available, and a recovery plan for the species is expected to be released in 2016; therefore, this species will be considered for inclusion in the 2022 CVFPP and Conservation Strategy. Other species that were considered during the initial screening could be reconsidered, and targeted conservation plans may be developed. These species include the western pond turtle (Actinemys marmorata), tricolored blackbird (Agelaius tricolor), western red bat (Lasiurus blossevillii), and western burrowing owl (Athene cunicularia hypugaea). 

CVFPP Conservation Strategy Appendix H. Central Valley Chinook Salmon Rearing Habitat Required to Satisfy the Anadromous Fish Restoration Program Doubling Goal

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

NewFields and Cramer Fish Sciences, in collaboration with the California Department of Water Resources FloodSAFE Environmental Stewardship and Statewide Resources

NewFields and Cramer Fish Sciences, in collaboration with the California Department of Water Resources FloodSAFE Environmental Stewardship and Statewide Resources Office Conservation Strategy team, applied best available tools and data to estimate the area of suitable juvenile salmonid rearing habitat required in each of the Conservation Planning Areas (CPAs) to achieve the Anadromous Fish Restoration Program (AFRP) “doubling goal” for Chinook salmon populations. The AFRP goal was used to align the Conservation Strategy objectives with existing,longstanding efforts by partner resource management agencies. Historical and existing suitable rearing habitat area for juvenile salmonids was estimated with the Estimated Annual Habitat approach that uses measured hydrology and modeled hydraulic relationships between river flow and inundation area to calculate areas of inundation with timing, duration, and frequency suitable for juvenile California Chinook salmon rearing. The rearing habitat required to support the doubling goal populations was estimated using the Emigrating Salmonid Habitat Estimation model. The details of the approach and the full range of calculated results are presented in the following sections and appendices.

CVFPP Conservation Strategy Appendix I. Floodplain Restoration Opportunity Analysis

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

As part of the Conservation Strategy for the 2017 Central Valley Flood Protection Plan (CVFPP), a continuation of the Floodplain Restoration Opportunity Analysis (FROA) (

As part of the Conservation Strategy for the 2017 Central Valley Flood Protection Plan (CVFPP), a continuation of the Floodplain Restoration Opportunity Analysis (FROA) (DWR 2012a) was conducted to develop, identify, and prioritize potential locations for implementing management actions. Two types of management actions were considered in this analysis: modification of floodplain topography (specifically, lowering floodplain topography through targeted excavation) and levee relocation (specifically, constructing setback levees). Preliminary areas for floodplain modification and setback levees were identified within the Systemwide Planning Area (SPA) of the State Plan of Flood Control (SPFC) (Figure 1-1). The following technical memorandum documents the goal, objectives, methods, and results of this analysis.

CVFPP Conservation Strategy Appendix J. Existing Conservation Objectives from Other Plans

The Conservation Strategy, in conjunction with the Central Valley Flood Protection Plan (CVFPP), geographically overlaps with multiple regional and collaborative conservation plans that have been implemented or are planned for the Sacramento and San Joaquin Valleys. Regional planning efforts such as the Conservation Strategy are most effective when coordinated with similar programs and plans, in terms of both cost efficiency and ecological benefit. For example, knowledge gained through implementation of existing plans has refined the Conservation Strategy’s objectives and approaches. Additionally, during strategy implementation, collaboration with other planning efforts will provide greater opportunities for effective, integrated, landscape-level conservation. This could support achievement of individual plans’ important ecological objectives, such as improving habitat connectivity and increasing the size of habitat preserves. In other words, the collaborative approach will allow the Conservation Strategy to contribute to the shared objectives of the other plans while meeting its own objectives.  The purpose of this appendix is to describe completed and ongoing planning efforts that have regional, geographically based, or quantifiable conservation measures that may be relevant to the Conservation Strategy. All of the plans and programs described overlap at least partially with the Systemwide Planning Area (SPA). The list presented herein is not comprehensive, but provides examples of efforts that were considered in developing the Conservation Strategy. In this appendix, completed planning efforts are summarized first, followed by those that are in progress. Potential relationships between these plans or programs and the Conservation Strategy are summarized in Table 1-1. Some programs, such as efforts to identify total maximum daily loads or implement Integrated Regional Water Management Plans, may support conservation work, but their objectives are dissimilar to those of the Conservation Strategy (i.e., focused on meeting water quality standards), so were not included.  This appendix is not intended to present an analysis of each plan in detail. Rather, the intent is to identify areas of potential overlap between relevant plans and the Conservation Strategy. As the Conservation Strategy is implemented, potentially synergistic areas and areas of possible conflict between the Conservation Strategy and individual plans can continue to be identified.  This appendix supports and recognizes considerations that will be essential as the Conservation Strategy is implemented. Specifically, this appendix:  • efficiently uses current information to inform the Conservation Strategy regarding potential conservation goals; recognizes that multiple conservation plans and collaborative planning efforts have been completed, are in development, or are being implemented: in whole or in part, the plans address many of the targeted species and habitats that occur in the SPA, and the plans help identify conservation needs and priorities in the flood risk management system; highlights potential conservation partnerships for the California Department of Water Resources (DWR) in implementing the Conservation Strategy, by: describing opportunities to share costs on conservation projects and describing opportunities for DWR to simultaneously meet its own conservation goals and contribute to plans or programs through specific projects; and identifies completed conservation planning efforts, from which “lessons learned” can be applied to Conservation Strategy implementation

CVPIA 10 Years of Progress

U.S. Bureau of Reclamation (USBR) | June 27th, 2015

In 1992, Congress passed the Central Valley Project Improvement Act (Act, or CVPIA), which amended previous authorizations of the California Central Valley Project (CVP)

In 1992, Congress passed the Central Valley Project Improvement Act (Act, or CVPIA), which amended previous authorizations of the California Central Valley Project (CVP) to include fish and wildlife protection, restoration, enhancement, and mitigation as project purposes having equal priority with power generation, and irrigation and domestic water uses. Congress directed the Secretary of the Interior, through the Bureau of Reclamation (Reclamation) and the U.S. Fish and Wildlife Service (Service), to operate the CVP consistent with the purposes of the Act, to meet the Federal trust responsibilities to protect the fishery resources of affected Federally recognized Indian tribes, and to achieve a reasonable balance among competing demands for use of CVP water. For the past 10 years, Reclamation and the Service, working together to implement the CVPIA, have embarked on one of the Nation’s largest fish and wildlife restoration efforts. Reclamation and the Service have developed programs to improve environmental conditions and modify operations, management, and physical facilities, and thus, the associated environmental conditions of the CVP to comply with the purposes and goals of the Act. All of the Act’s restoration measures are planned and implemented by Reclamation and the Service and coordinated with the State of California, CALFED, and other partners. In the following pages, you will find a summary of the protection, restoration, enhancement, and mitigation measures that have been implemented as of the end of fiscal year 2002, demonstrating the contributions Reclamation and the Service have made to the Central Valley. As you read the summary, it should become clear that progress is being made in unprecedented programs, and advancements have been made in resolving complicated watershed issues throughout the Central Valley. Yet much work lies ahead.

Debris-Restraining Barriers of the Yuba River

In the years following the discovery of gold in California, the processes of mining for this precious metal caused the removal of vast quantities of detritus from the western slopes of the Sierra Mountains into the streams and rivers of the valleys below. Gold was found in the beginning in gravel beds, where it had probably been deposited by rivers flowing in prehistoric times. These gravel beds exist in great numbers in a comparatively small area along the western slopes of the Sierra Mountains near the headwaters of streams draining into the Sacramento and San Joaquin valleys. In securing gold from these mountains the sorting action of water was necessary, and in order to facilitate mining operations. ditches of great length and size were built, frequently at great expense, to carry water to the localities where gold had been discovered. Streams of water under great pressures were directed at these gravel banks through nozzles sometimes as large as nine inches in diameter, to break down the gravel banks and wash the detritus through sluice ways where the gold could be caught. Streams carry ing as much as 3,500 miner's inches were not uncommon. It is thus easily seen that such powerful agencies would rapidly wash down whole hillsides, which would naturally be carried into the canyons and small streams in the vicinity of the mines, to be washed farther and farther down stream with each succeeding rainy season. These mining operations were carried on for a number of years without interruption until the valley country below became more thickly populated, when the injuries caused to the rivers and the neighboring farm lands became important enough to cause those damaged to seek legal redress.
