Farmers Thought They Had 20 Years To Use Groundwater As They Wished. Maybe Not Anymore

California farmers are laboring under a daunting edict: They must stop over-pumping groundwater from beneath their ranches. The saving grace is that state law gives them more than 20 years to do it. Now, however, a landmark court ruling could force many farmers to curb their groundwater consumption much sooner than that, landing like a bombshell in the contentious world of California water. For the first time, a California court has said state and county governments have a duty to regulate groundwater usage when it’s clear that the pumping drains water from adjacent rivers.
