Investigators are still trying to determine who hacked into the controls for Pixley Irrigation District’s main turnout off of Deer Creek last month.  A gate got stuck in “manual” mode when it should have operated remotely in automatic mode.  Pixley’s water resources superintendent Kirk Masters called the incident a “hiccup” that was discovered on June 22, the first day of the district’s summer water run. Masters reported it at Pixley’s July 9 board meeting and said the problem was rectified within two hours.  Masters said in his report that he was told it was Iranian hackers, but that has not been confirmed. … This incident comes on the heels of an Iranian hacker group attempting to gain access to California Water Service’s operational systems in Bakersfield, Visalia and Chico.
