Jim;
These two links below take you to the lists from the Calif.Gaming Control Comm.of the state government.Even their lists have some errors.

Card Rooms:
http://www.cgcc.ca.gov/cardrooms.shtml
Indian Casinos:
http://www.cgcc.ca.gov/tribalcasinos.shtml
(note this link goes to a .pdf file so you need
the Acrobat Reader to view it.)

These are said to be the open/active places.
I hope this helps.
Jim Noll
