The state’s extensive water system supplies cities and farms; prevents pollution of lakes, rivers, and coastlines; protects against floods; and supports freshwater ecosystems and the forested headwaters that are a major source of water supply. Many local, state, and federal agencies oversee this system and raise revenues from a variety of sources. California spends about $37 billion annually, with the lion’s share (84%) coming from local water bills and taxes. The balance comes from state (13%) and federal (3%) contributions.
