There is boat-in campsites on lake clementine. Reserve on reserve.ca.com
While I didn't see any designated calling facilities, as I was leaving late at night I did see a tent setup under a tree. However, much of the places are on a bed of rocks, so it may not be ideal for camping. There is a booth with state park employees where you pay for day tickets. I'd think you can ask them. I'll also ask next time I am there to find out.
