Farm region near Tulare Lake has been put on ‘probation’ as overpumping of water has caused faster sinking of ground

Even after two back-to-back wet years, California’s water wars are far from over. On Tuesday, state water officials took an unprecedented step to intervene in the destructive pumping of depleted groundwater in the state’s sprawling agricultural heartland.

The decision puts a farming region known as the Tulare Lake groundwater subbasin, which includes roughly 837 sq miles in the rural San Joaquin valley, on “probation” in accordance with a sustainable groundwater use law passed a decade ago. Large water users will face fees and state oversight of their pumping.

The move, which water officials reassured farmers would be lifted if local agencies progress on developing stronger sustainability plans to mitigate issues, is the first of its kind – but has been years in the making. Over-pumping of groundwater in this region has caused the land to collapse faster than in almost any other area in the country, in some places sinking more than a foot every year. Officials say the Tulare Lake groundwater subbasin failed for years to provide adequate plans to mitigate their well-known water problems.
