So I'm guessing the lake is just used for fishing and boating, but doesn't have a beach area like a lot of lakes around here (not counting the myriad of reservoirs).
That was the impression I got from earlier posts by the locals. That it used to be a swimming lake and might've had a beach, but now it's full of leeches and not a good place to swim. I'm trying to find it but I think Ollipop posted a pic of the sign near the lake that said it wasn't for swimming.
