the flow was 19,000 from which was average.  the highest its been was 33,000 cfs and the lowest has been 10,000.  the slowest time was just a few minutes over 6 hours.  100 out of the 103 people that attempted completed.  they said they would pull you out at 6 hours unless you were close.  it kicked a lot of peoples asses but they made it.  really good camaraderie and supportive people all around.  I definitely could not have made it at this point in my swimming.  people came from all over the country and a few from europe even.
