More than 20 people from the Water Entry Team responded to the call. They put boats in the water and were able to tie a rope around the man and pull him to safety downstream near Center Street.
Knoll says the man wasn't cooperating at first until he started to get cold. "He was telling our guys to stay away and not to touch him. I believe he was intoxicated."
The man was rescued before hypothermia set in. Paramedics say he had some minor cuts and scrapes from the jump but was otherwise O-K.
No streets were blocked off during the rescue attempt.
But, experts say no one should try and swim in the river this time of year. The temperature is below freezing and there's debris in the water that could lead to drowning.
