The price here is now $10 per day but if you have America the Beautiful Pass it's half price.

Couple downsides are that the bathrooms are pit style bathrooms and kind of nasty and unless you snag one of the sites far back in the woods you are pretty close to the highway so some noise.

It is my understanding that they are scheduled to update the bathrooms in the next year or two but until then I'd definitely suggest going to Arrowhead Point. It's right down the road, same price, quieter, and nicer bathrooms.
