So if i want to take my family i can just do it? Or do i have to go pay for me to stay the night at camp? And what about taking my boat do i have to pay to get it in the water?

We were there a couple weeks ago. No one came around to collect money and no one was in the toll booth. Dry camping but there was one chemical toilet.

Yes, at the Auxiliary Dam you must pay a day fee of 10.00 per day per vehicle unless you have any type of pass. As for your boat, you must get a Lake Isabella Lake pass which can be obtained at the Shell gas station in Lake Isabella.
