Yes. A number of the shark attacks in the Jersey shore shark attacks in 1916 were in rivers.
Those attacks were used as the basis for Peter Benchley'sbook and the movie Jaws.

No. The 1955 story is widely held to be a hoax. Additionally, a bull shark would die quickly if it was exposed to the frigid waters of Lake Michigan.

It seems that we could ask George Lawson, or any of his relatives, who would certainly know whether or not he was bitten by a shark. 1955 wasn't that long ago!
According to the Global Shark Attack File, in 1955 George Lawson had his right leg bitten off by a bull shark (Carcharhinus leucas) while swimming in Lake Michigan near Chicago. The attack was unprovoked and by surprise. The incident log does not mention any other attacks from Lake Michigan, so it appears the incident was an aberration. Bull sharks have been recorded in the Mississippi River. Additionally, it has been claimed that a series of dams and locks known as the Illinois Waterway, which connects the Mississippi River with Lake Michigan should prevent bull sharks from entering Lake Michigan. Furthermore, Lake Michigan bathers should not be too concerned, because bull sharks prefer warmer waters.
Well bull sharks have been found in alton il and lake Michigan was never connected to a ocean untell they made a canal i am not saying a shark will go through all the boat locks but it is possible. And for the people that say lake Michigan is not connected to a ocean nees to go back to class cause it is back during world war 2 they had air craft carries in chicago
There have been no reports of shark sitings in Lake Ontario, even the bull shark hasn't been there. I wouldn't worry too much though as sharks tend to like warm water and Lake Ontario seems a little to far north for that to be an issue.
