Tuxbury pond is an artificial lake created by a dam.

You can tell, too. It's a weird lake. Most of it is super shallow, except for a narrow winding channel that's very deep, which I assume is the original river.

Even with a kayak, I had to do a lot of zig-zagging to get across the lake. I could MOSTLY go over the shallow parts, but it wasn't worth it, because I was plowing throw lilly-pads and other shallow-water plants. Which just makes the paddling harder for no reason.
