We talked to the wife who stated her husband jumped into the river to cool off after putting the canopy on the boat and got swept downstream by the current.  She said he was struggling so she jumped in to save him. She said she was able to swim to the shore of an island and walked along the bank looking for her husband. She then swan across the channel to get to a house to call for help. From the time he went under water to the time she called was about 30 to 45 minutes. Neither were wearing a life preserver.
