I posted this yesterday on a whitewater forum.
While I applaud the deputy for his actions....Here are some things to consider:
The Platte has been running near flood stage since May. This was no secret, as the fire dept, and counties have had all the ramps closed.
The deputy was not wearing a PFD. (One of the first things you are taught in swiftwater rescue is that if you don't have the gear, DON'T GET IN THE WATER. It only creates more victims.)
It was a brave move, and probably saved the girls life, but painfully illustrates why medals and commendations for bravery are so often awarded posthumously.
So as I have said, I don't fault the deputy. Honestly, if I was put in that situation, whether it was considered "my job" or not, I would have probably done the same thing. However, there is a lesson to be learned here. The river never gets tired. 1 CFS of water has a force of 62 lbs/sqft. River flow on that day was right at 8,000 cfs. That means that there was 496,000 lbs of force moving downriver. I don't care who you think you are, you don't have a chance.
