Yes they can
You can if you like.
People definitely do. I had fun in the water (definitely that sort of muddy, dark brown of a warm body of water) but might be more of a splashing around than an actual swim kind of place
Me and a couple friends of mine took our dogs there they swim the dogs that is and there was people fishing but I don't know to me the water looked a little dirty but I suppose maybe you could swim very small little Beach it's more just kind of like a picnic and kind of grill area
