Castaic Lake Fishing Overview

Water Description

Castaic Lake is renowned for its big largemouth bass fishing. The lake features a 2,000-acre main section and an adjoining lagoon. Both sections provide elite fishing for trophy-sized fish. Introduced with Florida-Strain bass in the 1970s, Castaic saw a major growth in both the number and size of these fish. Enormous bass weighing up to 20 pounds have been documented, with 10-plus pounders being somewhat common. It's not unlikely to hook multiple bass in the 3-5 pound range. The largemouth bite dominates the lake in spring and summer. Though...

Castaic Lake is renowned for its big largemouth bass fishing. The lake features a 2,000-acre main section and an adjoining lagoon. Both sections provide elite fishing for trophy-sized fish.

Introduced with Florida-Strain bass in the 1970s, Castaic saw a major growth in both the number and size of these fish. Enormous bass weighing up to 20 pounds have been documented, with 10-plus pounders being somewhat common. It's not unlikely to hook multiple bass in the 3-5 pound range. The largemouth bite dominates the lake in spring and summer.

Though largemouth fishing is the primary attraction, a strong population of smallmouth and a yearly stocking of rainbow trout (a major food source for the big largemouth) provide cool water action for anglers outside of the warmer months. Anglers also target stripers, channel cats, and panfish at Castaic.

Good Striped Bass bite

Jim Taibi reports a productive post-spawn bass bite at Castaic Lake, with both largemouth and smallmouth hitting well, although most are only in the 1–2 lb range. Right now, they are holding tight to steep rock banks, walls, and secondary points in 10–20 feet of water. Dropshots, small paddletail swimbaits, and wacky Senkos are all working well. A...

Jim Taibi reports a productive post-spawn bass bite at Castaic Lake, with both largemouth and smallmouth hitting well, although most are only in the 1–2 lb range. Right now, they are holding tight to steep rock banks, walls, and secondary points in 10–20 feet of water. Dropshots, small paddletail swimbaits, and wacky Senkos are all working well. A light topwater window is opening up at dawn and dusk, drawing out some higher-quality female bass that are starting to shake off their post-spawn sluggishness.

Stripers are wrapping up their spawn and moving into more predictable feeding patterns. Some are tracking bait into the coves around 20–30 feet deep, where 3” swimbaits, spoons, and Alabama rigs are getting fish. There are signs of the trolling bite starting to take off as schools tighten up.

The lake’s full, water clarity is improving at 5–15 feet, and surface temps are hovering between 71–76°F. Launching is at West Ramp only.

Bass action is wide open. Jim Taibi reports consistent action for both Largemouth and Smallmouth, with catch counts hitting 15–20 a day. Dropshot rigs are doing the most damage, but any finesse plastics or small 3″ swimbaits are working well. Bigger bites are coming on wacky-rigged Senkos fished along rocky slopes and secondary points. The bite’s...

Bass action is wide open. Jim Taibi reports consistent action for both Largemouth and Smallmouth, with catch counts hitting 15–20 a day. Dropshot rigs are doing the most damage, but any finesse plastics or small 3″ swimbaits are working well. Bigger bites are coming on wacky-rigged Senkos fished along rocky slopes and secondary points. The bite’s active but scattered… folks are doing best moving spots frequently.

Stripers are in transition. Bait is moving into coves like Elizabeth Canyon, and while a few fish are feeding, most surface activity is tied to spawning. They’re not chasing—just going through the motions. Unlike bass that guard nests, Stripers release everything into open water and let the wind do the mixing. During this phase, they’re tough to fool. A couple might swipe, but the real action should return post-spawn.
