Seeking to prevent the California State Water Resources Control Board from stepping in to regulate groundwater in critically overdrafted subbasins, local agencies are working to correct deficiencies in their plans to protect groundwater. With groundwater sustainability agencies formed and groundwater sustainability plans evaluated, the state water board has moved to implement the 2014 Sustainable Groundwater Management Act, or SGMA. … Under probation, groundwater extractors in the Tulare Lake subbasin face annual fees of $300 per well and $20 per acre-foot pumped, plus a late reporting fee of 25%. SGMA also requires well owners to file annual groundwater extraction reports.
