We stayed in late June in the Rocky Cove Campground on the lake.  The lake itself is dotted with campgrounds.  Rocky Cove has concrete pad sites, nice and level, both on and away from the lake.  The lake sites have power only, and the Prime sites (opposite the lakeside sites) have water and power both.  We don't have water in our teardrop, so we got water from an unoccupied site.  

The sites are small, and for the summer, don't stay in site #118 (a lakeside site), as it has no protection from the sun.  The sun sets across the lake and although the view is great, the sun bakes the campsite from morning until 9 pm.  The site next door, #120 is nice and shady.  In winter, the desirability of the sites might be reversed.

The odd thing about the campground is that there is no bathroom or showers.  At all.  You have to go to the next campground over, Oak Point.  Not convenient.  Overall, Oak Point appears to be the better choice, with more trees, larger sites and a convenient bathroom (with ice machine at the entrance).  I should note the restroom was "clean enough".  Not terrible, not great.  The shower I used had merely a trickle, but my wife's had great pressure.  The hand dryer in the men's room looked corroded and was out of order (in Oak Point)

All the campgrounds appeared quiet, and the people there were friendly.  We would go back, but stay in Oak Point.
