That's a longnose gar, which is native to the Lakes. I believe shortnose and spotted gar also naturally occur in at least parts of the Great Lakes.
The gar in the news item was an alligator gar (or at least appeared to be; I couldn't get a good enough look to rule out shorty or spotted); these are inhabitants of the lower Mississippi and other gulf drainages, and are much much larger than other gar; they can reach over 10 feet in length.
