Description: 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
