February 14, 2019 - In this report, we assess several of the Governor’s budget proposals in the natural resources and environmental protection areas. Based on our review, we recommend various changes, as well as additional legislative oversight. We provide a complete listing of our recommendations at the end of this report.
January 9, 2020 - This post summarizes the current efforts being undertaken by state departments to assess the vulnerability of state facilities to the future impacts of climate change. We find that most state agencies are only in the early stages of conducting such assessments, which are a critical first step of a multistep process of planning to reduce risks to state assets and public services. We provide a number of oversight questions the Legislature can use to monitor what progress is being made by individual state departments.
November 21, 1991 - Despite heavy rains in March 1991, California continues to face a serious near-term water problem resulting from five years of drought. In fact, the amount of water in storage on October 1, 1991 was about equal to the amount in storage one year ago—a year in which strict conservation measures were imposed in some areas and there were significant reductions in water supplies for many agricultural users. In this paper, we provide background information on California's water system, the impact of the drought, water needs in the future, and legislative options for coping with water supply limitations.
March 22, 2017 - This report is intended to provide basic information about floods and flood management in California. (Whereas previous generations referred to “flood control” or “flood prevention” activities, experts now prefer the term “flood management” in acknowledgement that floodwaters are recurring and inevitable.) We begin by summarizing the history, causes, and risk of floods across the state. We then describe flood management agencies, infrastructure, and strategies, as well as how governmental agencies typically respond when floods occur. Next, we describe the spending levels and funding sources currently supporting flood management efforts, as well as estimates for how much additional funding may be needed to improve those efforts. We conclude by highlighting some key challenges confronting the state in contemplating how best to manage floods in California.

October 20, 2008 - California’s water delivery system is facing a series of challenges due in part to a combination of increasingly variable weather conditions, legal requirements, and system operation and conveyance constraints. These challenges affect water availability, reliability, and delivery. Recent public and private efforts have sought ways to address these challenges. These measures include proposals to increase water through groundwater storage, surface storage, infrastructure changes, and system operation improvements, among others. This report provides, through a “quick reference” document relying heavily on charts to present information, a snapshot of water in California, including: (1) An Overview of California’s Water Governance; (2) Water Supply, Source, and Delivery; (3) How Do We Finance Water Projects? (4) What Drives the Cost of Water?, and (5) Issues for Legislative Consideration
January 15, 2015 - The Sacramento-San Joaquin Delta (Delta) is a biodiverse ecosystem that covers about 1,150 square miles and supports over 700 species of fish and wildlife. The Delta is an important source of water for the state and is used to convey water from Northern California to Southern California. The Delta faces several significant problems, including: (1) a decline in key native fish species, (2) reductions in the amount of Delta water available for use elsewhere, (3) water pollutants that cause harm to species and increase treatment costs, and (4) levees at significant risk of failure. The state has engaged in numerous efforts to address these problems and achieve its "coequal goals" for the Delta: water supply reliability and ecosystem restoration. There are many opportunities for the Legislature to improve the success of these efforts. We identified several issues for its consideration, including (1) demands for Delta water, (2) uncertain funding sources and slow implementation of some key activities, (3) limits on the effectiveness of governance in the Delta, and (4) challenges to restoring the Delta ecosystem. By addressing some of these issues, the Legislature can improve the likelihood that its goals and objectives for the Delta will be realized.
