They jumped in when boat motor failed

GENOA,Wis. — Seven people were sucked through a gate on the Mississippi River dam at Genoa after their boat lost power.  None were injured seriously, which Genoa Chief Mike Hanson called a miracle. The boaters had tried to paddle out of danger. But with their boat plainly in peril, they jumped off and grabbed logs or anything floating and rode their way through a roller gate. Hanson said people have gone through the dam before and died.: “This is one of very rare times somebody actually has lived through it.” The acccident was about 1:40 p.m.
