Not at the campground itself, but there's a marina and Sarges Dive Shack I believe is the name. I haven't been over to that part myself, but my in-laws did, said the guy wasn't that friendly.
Call them
At Sarges, not the Campground itself
The marina or the lighthouse retreat out on u.s.19 at Mt Nebo rents boats thats the only 2 places I know of.
I second what stephen krebs said. The people are not too friendly there.
