In 2008, a pair of divers from the Rochester region, Jim Kennard and Dan Scoville, discovered the wreck of a British Warship, the HMS Ontario, lost in 1780 during the American Revolutionary War. This shipwreck is the oldest ever found in the Great Lakes region. Both storms and wars have taken their toll on many ships traversing the Great Lakes and now many scuba divers find that the waters of Lake Ontario are a treasure trove of adventure. Over 200 shipwrecks are believed to be hidden under the murky waters of Lake Ontario.
P.S. Lake Ontario is a Great Lake, and is not one of the Finger Lakes, but it borders the northern shores of the Finger Lakes region.
