I live about an hour from Lake Castaic! As I recall someone caught a 50lb plus striped bass there a couple of years ago. The lake is famous for its Florida Strain largemouth bass. I believe the second largest bucketmouth ever caught came from Castaic, and it was just shy of 22 lbs. Some feel the lake could still yield the next world record bass. That whole chain of lakes is fed by the California Aqueduct, including San Luis Resevoir, where the current world record was caught. A smaller lake North of Castaic yields plenty of stripers up to 30 lbs. That is Pyramid. Most guys fish right after the trout plants. Big stripers love rainbow trout. The AC Plug was designed to imitate trout, and many a big striper has fallen victim of that plug, including a few over 60 lbs. I have fished Quail lake(another lake in the chain) but haven't had much success there. My specialty is the canal itself.
