I came here for one night (a Saturday) and there were plenty of spots available for first come first serve. That said, it is an 18 mile long dirt road to get in so it would stink to get there and not find a spot. I would reserve if possible. The camping spots were clean and the toilets were in good shape. Prepare yourself for a lot of biting insects so I would bring a screen house if you are staying for more than one night. The lake was gorgeous!
