    The Original Rule Was Intended To “Shorten And Streamline” Federal Land Use Planning While Being “More Transparent And Accessible” A 2008 And 2009 Biological Opinion Found That The Central Valley Project And State Water Operations Would Threaten Endangered Species And “Destroy Or Adversely ModiFy” Critical Habitat. “The 2008 and 2009 BiOps found that the Central Valley Project and State Water Project operations would jeopardize the continued existence of listed species, including endangered Sacramento River winter-run Chinook salmon, threatened Delta smelt, and threatened Central Valley steelhead, and would destroy or adversely modify these species' designated critical habitat.” [California Attorney General Xavier Becerra Press Release, accessed 10/07/20] In 2019, The Fish And Wildlife Service Was Told To Prepare A New, More Limited Environmental Review Of The Shasta Dam. “This year the Interior Department’s Fish and Wildlife Service was told to prepare a new environmental review of the dam project, but this one will be much more limited in scope, according to a person familiar with the plans, who requested anonymity out of fear of retribution. The new plan would not analyze the effects on salmon habitat downstream or the effects on several rare species.” [New York Times, 09/28/19] The New Biological Opinion Weakened Protections For The Delta Smelt, Allowing Large Amounts OF Water To Be Diverted From The San Francisco Bay Delta. “The Trump administration on Tuesday moved to weaken protections for a threatened California fish, a change that would allow large amounts of water to be diverted from the San Francisco Bay Delta to irrigate arid farmland and could harm the region’s fragile ecosystem.

Bridging the Safe Drinking Water Gap for California’s Rural Poor By Camille Pannu* Spurred by decades of inaction and continued exposure to unsafe drinking water, community leaders from California’s disadvantaged communities1 (DACs) advocated for the creation of a human right to water2 under state law.3 Shortly * Camille Pannu is the Director of the Water Justice Clinic, Aoki Center for Critical Race and Nation Studies at UC Davis School of Law. I thank the residents of California’s disadvantaged communities, and the organizations that amplify their voices, for their tireless efforts to extend water justice to our state’s most vulnerable people. Additionally, I thank Olivia Molodanof, Jessica Durney, and the Editors of the Hastings Environmental Law Journal for their patient and thoughtful editing. All errors are, of course, my own. 1. “Disadvantaged community” has become a legal term of art for an alternative poverty measure that compares a community’s relative socioeconomic status (median household income) to the statewide median household income level.

  • Panoche Valley
    THE Santa Clara Valley Audubon Society Established 1926 AVOCET The Newsletter of the Santa Clara Valley Audubon Society September-October 2017 Panoche Valley: Saving an Important Bird Area (IBA) by Shani Kleinhaus, Environmental Advocate oncluding almost eight years of advocacy and litiga- tion, SCVAS, Sierra Club Loma Prieta Chapter, and Defenders of Wildlife have signed a settlement agree- Cment that allows a photovoltaic solar farm to be built on about 1,000 acres of Panoche Valley floor, while at the same time preserving 26,000 acres, including 4,000 acres of valley floor grasslands, as habitat for endangered species. Califor- nia Department of Fish and Wildlife and Con Edison have also signed the agreement. We are proud of this achievement! Monterey Audubon Society first alerted SCVAS to the plans to construct a solar farm in Panoche Valley. In 2009, plans for solar arrays and supportive infrastructure encompassed most of the valley floor, as well as Little Panoche Valley. No mitigation was offered for the inevitable loss of habitat for the many endangered species that call the valley home, so we started mobilizing. In early 2010 we organized a work- shop that formed an alliance of farmers and environmental organizations in opposition to the project. This alliance has never faltered. In the years that followed, our advocacy and permit require- ments by state and federal wildlife agencies resulted in changing project ownership as investors came and went. The project footprint shrunk and mitigation lands were added. San Benito County produced additional environmental re- view documents, asserting repeatedly that the construction of a solar project on thousands of acres of valley floor could Ferruginous Hawk by Debra Shearwater cont’d on page 4 Wednesday, September 20, 2017 Cuba - The Isle of Endemics: Birds and Bats! with Dave Johnston Wednesday, October 18, 2017 Understanding California's Whales with Ted Cheeseman The Avocet 1 Please carpool if possible; bring binoculars, field guides, layered September-October Field Trips clothing.

  • A Century of Delta Salt Water Barriers
    A Century of Salt Water Barriers in the Delta By Tim Stroshane Policy Analyst Restore the Delta June 5, 2015 edition Since the late 19th century, California’s basic plan for water resource development has been to export water from the Sacramento River and the Delta to the San Joaquin Valley and southern California. Unfortunately, this basic plan ignores the reality that the Delta is the very definition of an estuary: it is where fresh water from the Central Valley’s rivers meets salt water from tidal flow to the Delta from San Francisco Bay. Productive ecosystems have thrived in the Delta for millenia prior to California statehood. But for nearly a century now, engineers and others have frequently referred to the Delta as posing a “salt menace,” a “salinity problem” with just two solutions: either maintain a predetermined stream flow from the Delta to Suisun Bay to hydraulically wall out the tide, or use physical barriers to separate saline from fresh water into the Delta. While readily admitting that the “salt menace” results from reduced inflows from the Delta’s major tributary rivers, the state of California uses salt water barriers as a technological fix to address the symptoms of the salinity problem, rather than the root causes. Given complex Delta geography, these two main solutions led to many proposals to dam up parts of San Francisco Bay, Carquinez Strait, or the waterway between Chipps Island in eastern Suisun Bay and the City of Antioch, or to use large amounts of water—referred to as “carriage water”— to hold the tide literally at bay.

Lindsey Foreword The Sacramento-San Joaquin Delta (Delta) is a major source of drinking water for 25 million people of the State of California. Therefore, the quality of Delta water is an important consideration for its use as a drinking water source. However, Delta water quality may be degraded by a variety of sources and environmental factors. Close monitoring of Delta waters is necessary to ensure delivery of high quality source waters to urban water suppliers.

  • Delta Region Drinking Water Quality Management Plan
    DELTA REGION DRINKING WATER QUALITY MANAGEMENT PLAN DRAFT FINAL June 2005 Funding for this project was made possible by a CALFED Grant through the Drinking Water Quality Program This document was funded by the CALFED Water Quality Program as an initial effort to create Regional “Equivalent Level of Public Health Protection” Plans and to assist in establishing a uniform framework in such planning. It is not intended to be a final document. California Bay-Delta Authority and CALFED WQP Implementing Agency staff have not had the opportunity to review and comment on this document, and any opinions or interpretations of the CALFED program expressed within the document are solely those of its authors. The CALFED WQP is committed to working with these and other parties to continue development and refinement of Regional Plans. EXECUTIVE SUMMARY In 2004, the CALFED Bay-Delta Program (CALFED) commissioned a pilot program for development of regional drinking water quality management plans (i) to identify the drinking water quality issues and needs of drinking water agencies in different regions of California and (ii) to develop solutions to address those needs. This Delta Region Drinking Water Quality Management Plan (DRDWQMP) was developed jointly by Contra Costa Water District (CCWD), the city of Stockton (COS), and Solano County Water Agency (SCWA). Figure ES-1 shows the Sacramento-San Joaquin Delta (Delta) region, with an outline representing Delta boundaries as defined in California Water Code Section 12220, along with the service areas of the three participating agencies. These three agencies represent the largest urban water users within the Delta region.
