Lake Como was a lake in Italy on Earth. In 2373, Tom Paris had a holoprogram called Sailing on Lake Como which he suggested to B'Elanna Torres in case she ever had a free evening, but she refused, stating that she'd rather take her chances with Freddy Bristow. (VOY: "The Swarm") According to the Star Trek Encyclopedia (4th ed., vol. 1, p. 452) , this lake, located near the community of Como in northern Italy, was about fifty kilometers long.
