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.

Guide Jim Taibi from 611 Fishing reports that bass action at Lake Castaic is still going strong. Largemouth and smallmouth are scattered across the lake in various stages of the spawn, with fish showing up on rocky points, main lake structure, and tucked into the brush in the backs of coves.

Guide Jim Taibi from 611 Fishing reports that bass action at Lake Castaic is still going strong. Largemouth and smallmouth are scattered across the lake in various stages of the spawn, with fish showing up on rocky points, main lake structure, and tucked into the brush in the backs of coves. Most largemouth are in the 1–2 lb range, with some bigger fish to 5 lbs. Water clarity is excellent overall, minus some stain deep in the coves. C3 Baits Shimmy’s in Neptune Shad on a Carolina rig or dropshot are doing most of the work, while wacky-rigged 5” Senkos in green pumpkin or natural shad are pulling the better bites. Jerkbaits and small cranks are starting to come into play too. As for stripers, not much pressure on them yet, but with baitfish moving shallow, it won’t be long before the big schools follow.

Good Bass bite
Trout, Bass, Striped Bass
60°F Clear

Castaic saw bass pushing shallow in pre-spawn mode last weekend with temps near 90, but that flipped after a bluestone algae treatment midweek, according to guide Jim Taibi from 611 Fishing. The shoreline bite died off as fish retreated deeper, and cooler weather didn’t help. Water’s clearing again and the bite should rebound soon, even with storms...

Castaic saw bass pushing shallow in pre-spawn mode last weekend with temps near 90, but that flipped after a bluestone algae treatment midweek, according to guide Jim Taibi from 611 Fishing. The shoreline bite died off as fish retreated deeper, and cooler weather didn’t help. Water’s clearing again and the bite should rebound soon, even with storms ahead. Most Largemouth and Smallmouth are 1–2 lbs, with a few bigger ones showing in a recent tournament. Jim reports Carolina-rigged C3 Shimmy’s and Ridgeback Reapers are working, along with a growing Senko bite around deeper points and bluffs.

Stripers are slow but should pick up as the weather stabilizes—bait’s holding at 30 feet. Recent trout plants kicked off some shore action before the algae treatment. Water temps 58–61, clarity 10–20 feet
