Regulators just imposed unprecedented fees on water usage in the state’s agricultural heartland.
In much of the United States, groundwater extraction is unregulated and unlimited. There are few rules governing who can pump water from underground aquifers or how much they can take. This lack of regulation has allowed farmers nationwide to empty aquifers of trillions of gallons of water for irrigation and livestock. Droughts fueled by climate change have exacerbated this trend by depleting rivers and reservoirs, increasing reliance on this dwindling groundwater.
In many places, such as California’s Central Valley, the results have been devastating. As aquifers decline, residential wells start to yield contaminated water or else dry up altogether, forcing families to rely on emergency deliveries of bottled water. Large-scale groundwater pumping has also caused land to sink and form fissures, threatening to collapse key infrastructure like roads, bridges, and canals. These local impacts have been the price of an economic model that provides big farmers with unlimited access to cheap water.
At a tense 12-hour hearing that lasted well into the night on Tuesday, California officials struck a big blow against that model. The state board that regulates water voted unanimously to take control of groundwater in the Tulare Lake subbasin, one of the state’s largest farming areas, imposing a first-of-its-kind mandatory fee on water pumping by farmers in the area.
The decision to place the basin’s water users on “probation,” a punishment for not managing their water effectively, could force some of the region’s largest land barons to pay millions of dollars in fees or stop cultivating huge sections of their farmland.

The vote sets up a high-stakes enforcement fight with some of the state’s most powerful farmers, who have fought for years to avoid state intervention on their profitable dairy pens and tomato fields. The state will start measuring water usage and collecting fines later this year, but it has never attempted any such enforcement action before, and there is no way to know yet whether farmers will comply with the fees.
The larger question is whether the state’s policing effort will succeed in forcing a long-term reduction in groundwater usage in the state’s agricultural areas. The success or failure of this effort matters not just for California but also for many other pasture-rich states, from Nevada to Nebraska, that are trying to police their groundwater. If the Golden State can cut water usage without causing political or economic upheaval, it will leave a blueprint for other states trying to manage scarce water.
“Groundwater is one of these collective resources where your pumping has an impact on a lot of other people, and you have to have a mechanism to manage that,” said Ellen Hanak, an economist and water expert at the Public Policy Institute of California, a think tank. “I seriously doubt that the state wants to be taking over basins and managing them, but there has to be a backstop.”
The probation vote for Tulare Lake comes almost a decade after the California lawmakers passed the landmark Sustainable Groundwater Management Act, which requires water users in threatened areas across the state to draft plans for healing their depleted aquifers by 2040. The Central Valley pumps around […]
