Fresh Water

There are three small islands forming the shape of a right triangle.  There is an underwater island too.  If the underwater island was tall enough to be a regular island, the four islands would make a rough square.  On the island closest to our point, there's a long rock bar that juts out under the surface for 30 or 40 feet.  I like to go out there and sit on the smooth stones and watch the tiny waves break.

The bottom of the lake is soft, murky and dark.  But the water is crystal clear.
