There is no single place to look up what a California water or irrigation district charges. We pulled hundreds of agencies into one structured dataset, with a live source behind every rate. The picture is stark: farms pay a small fraction of what households pay for the same acre-foot, and across much of the state agricultural water is cheap enough to mute any reason to use it more efficiently.
This interactive piece maps the gap district by district — searchable, sortable, with a source link behind every number — and argues that California's water trouble is a management problem as much as a scarcity one.
