Three individuals were floating Jefferson River (2 males, 1 female) and canoe became lodged on center pilon of concrete bridge and folded in half around pilon.  The two male subjects were able to exit canoe upon impact with bridge.  The female victim had her right foot caught below the crease/fold in the canoe and could not free herself from the canoe.  Finally, after 4 hours, we elevated the canoe to get water pressure off the canoe and freed victim from the canoe.
