Twin Falls city officials are telling residents on the city water system to refrain from using water at this time.  Heavy winds yesterday afternoon blew down some power lines that operate the four pumps at the Blue Lakes water source.  Idaho Power crews have been on the scene all night but the heavy winds made repairing the downed lines difficult.  Officials say if the city runs clear out of water there would be no water to fight any fires.  Officials say the situation is close to critical and ask all residents to refrain from using water this Tuesday morning.  We will have more information as soon as it is available.
