The Deeps is a popular spot on Lester River.  It's also a very dangerous spot where several kids have drowned over the years, so definitely keep that in mind and be safe if you ever visit it.  YouTube user MNduroUSA scuba dived to see what was at the bottom.  It's pretty cool to see the wildlife such as large crayfish, trout, and other fish, along with some man made items that have fallen in there.
