Stanislaus County supervisors adopted a well mitigation and management plan Tuesday for the groundwater underlying most of the northern part of the county. County government has jurisdiction over the eastern and western unincorporated areas that are not within irrigation districts — about 22% of the groundwater basin. … According to a report Tuesday from county Water Resources Manager Christy McKinnon, groundwater levels are expected to decline before management efforts reverse the pattern. Almost 30 wells are at risk of failing if there is no action.
