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.
