Castaic Lake - Castaic, CA

Lake Information

Fish Species: Striped Bass, Channel Catfish, Rainbow Trout, Largemouth Bass, Black Crappie, Smallmouth Bass, Bluegill, White Crappie
Castaic Lake, located in Los Angeles County, is a premier Southern California reservoir known for its trophy largemouth bass and robust striped bass population. This large, deep lake supports year-round fishing for bass, catfish, panfish, and seasonal trout.

Spring is the most productive season for largemouth bass, with anglers targeting spawning fish using swimbaits, jigs, and soft plastics around brush, rocks, and drop-offs. Post-spawn, drop-shot and deep crankbait tactics excel. Striped bass school in open water and respond well to trolling, cut bait, or vertical jigging, especially near the dam and main channel.

Catfish are abundant and grow large, especially in coves and creek arms. Chicken liver, mackerel, and commercial stink baits are effective at night. Crappie and bluegill are found in shallows near submerged structure and offer fun spring and summer action using live bait or jigs.

Castaic Lake provides ample access, with boat ramps, marinas, and shoreline trails. Watercraft are popular, but float tubers and bank anglers can also do well in quieter coves. With a reputation for producing double-digit bass and consistent striped bass action, Castaic Lake remains a top-tier multispecies destination for serious Southern California anglers.
