Transitions for the Delta Economy
Transitions for the Delta Economy January 2012 Josué Medellín-Azuara, Ellen Hanak, Richard Howitt, and Jay Lund with research support from Molly Ferrell, Katherine Kramer, Michelle Lent, Davin Reed, and Elizabeth Stryjewski Supported with funding from the Watershed Sciences Center, University of California, Davis Summary The Sacramento-San Joaquin Delta consists of some 737,000 acres of low-lying lands and channels at the confluence of the Sacramento and San Joaquin Rivers (Figure S1). This region lies at the very heart of California’s water policy debates, transporting vast flows of water from northern and eastern California to farming and population centers in the western and southern parts of the state. This critical water supply system is threatened by the likelihood that a large earthquake or other natural disaster could inflict catastrophic damage on its fragile levees, sending salt water toward the pumps at its southern edge. In another area of concern, water exports are currently under restriction while regulators and the courts seek to improve conditions for imperiled native fish. Leading policy proposals to address these issues include improvements in land and water management to benefit native species, and the development of a “dual conveyance” system for water exports, in which a new seismically resistant canal or tunnel would convey a portion of water supplies under or around the Delta instead of through the Delta’s channels. This focus on the Delta has caused considerable concern within the Delta itself, where residents and local governments have worried that changes in water supply and environmental management could harm the region’s economy and residents. -

CALIFORNIA FISH and GAME ' CONSERVATION of WILDLIFE THROUGH EDUCATION'
REPRINT FROM CALIFORNIA FISH and GAME ' CONSERVATION OF WILDLIFE THROUGH EDUCATION' . VOLUME 50 APRIL 1964 NUMBER 2 ANNUAL ABUNDANCE OF YOUNG STRIPED BASS, ROCCUS SAXATILIS, IN THE SACRAMENTO- SAN JOAQUIN DELTA, CALIFORNIA' HAROLD K. CHADWICK Inland Fisheries Branch California Department of Fish and Game INTRODUCTION A reliable index of striped bass spawning success would serve two important management purposes. First, it would enable us to determine if recruitment is directly related to spawning success. If it is, we could predict important changes in the fishery three years in advance. Second, it would give insight into environmental factors responsible for good and poor year-classes. Besides increasing our understanding of the bass population, this knowledge might be used to improve recruit- ment by modifying water development plans in the Sacramento-San Joaquin Delta under the State Water Resources Development System. Fyke net samples provided the earliest information on young bass distribution (Hatton, 1940). They were not promising for estimating abundance, and subsequent sampling of eggs and larvae with plankton nets also had important limitations (Calhoun and Woodhull, 1948; Cal- houn, Woodhull, and Johnson, 1950). An exploratory survey with tow nets in the early summer of 1947 (Calhoun and Woodhull, 1948) found bass about an inch long dis- tributed throughout the lower Sacramento-San Joaquin River system except in the Sacramento River above Isleton. This suggested the best index of spawning success would be the abundance of bass about an inch long, measured by tow netting. In 1948 and 1949 extensive tow net surveys were made to measure the relative abundance of young bass in the Delta between Rio Vista and Pittsburg (Erkkila et al., 1950). -

Summary “Once a landscape has been established, its origins are repressed from memory. It takes on the appearance of an ‘object’ which has been there, outside us, from the start.” Karatani Kojin (1993), Origins of Japanese Literature The Sacramento–San Joaquin Delta is the hub of California’s water supply system and the home of numerous native fish species, five of which already are listed as threatened or endangered. The recent rapid decline of populations of many of these fish species has been followed by court rulings restricting water exports from the Delta, focusing public and political attention on one of California’s most important and iconic water controversies. -

The Delta RMP stakeholder panel kickoff meeting is scheduled for 30 September 2008 and we respectfully request your attendance at the meeting. The meeting will consist of two sessions (see attached draft agenda). During the first session, Water Board staff will provide an overview of the impetus for the Delta RMP and initial planning efforts. The purpose of the first session is to gain management-level stakeholder input and, if possible, endorsement of and commitment to the Delta RMP planning effort. We request that you and your designee attend the first session together. The second session will be a working meeting for the designees to discuss the details of how to proceed with the planning process. A brief discussion of the purpose and background of the project is provided below. In December 2007 and January 2008 the State Water Board, Central Valley Regional Water Board, and San Francisco Bay Regional Water Board (collectively Water Boards) adopted a joint resolution (2007-0079, R5-2007-0161, and R2-2008-0009, respectively) committing the Water Boards to take several actions to protect beneficial uses in the San Francisco Bay/Sacramento-San Joaquin Delta Estuary (Bay-Delta).
