"The Loch Ness Monster, maybe," said Chris Mondoli.

Carlos Rubio was with his son last weekend when he got video of what appears to be a large turtle, about the size of a spare tire.
"At first I thought it was a boulder moving in the water. I realized it was a pretty big snapping turtle," said Rubio.
"They get really large. They're prehistoric," said Wendy Rozonewski.

Recently, the world was introduced to an alligator snapping turtle nicknamed "Chonkosaurus" that was spotted on the Chicago River.
The turtle in the lake is likely smaller, but it's creating a big stir about what lies beneath.
"There are things in there we probably don't know about that are living here," said Cary Port.
After a long search, we had no luck finding the reptile on our visit.
"The search continues," Mandoli said.
