Great for everything but swimming
This lake has great walking/biking paths winding in and out of the trees, and connecting multiple lakes, playgrounds for the kids, scores of people, beaches, volley ball courts, docks, and a pavillion that sells basic goodies during the day. Great for running, biking, sailing, playing with the kids.
Not the cleanest water in the world; years of use has turned it a sour brown, but still safe for the kids to play in. I personally won't go in the water unless I have to.
