There are three private spots that I found. Two on the right hand side of the road. And another if you turn left on the road that is closer to the first parking area. It will be on the left.

The lower campsites on the lake looked far apart when we camped up by the dam. There were no obvious designated spots by the dam, we just parked on the gravel area. There was one tent camper nearby, but not close. We did not see any bathrooms. The view and the mountain goats were amazing!
