Castaic Lake Bass Fishing Report: April 26, 2026

Your weekly intel from guide Jim Taibi of 661Fishing.com — presented by TackleExpress.com

Spring is doing its thing at Castaic Lake, and if you know where to look — and what to tie on — the bass are absolutely there for the taking. This week brought high winds mid-week and fluctuating water levels that pushed fish deeper and off their usual haunts, but guide Jim Taibi still found the bites. Here's exactly what's working, what's not, and how to put more fish in the boat this week.

What's Biting: Largemouth & Smallmouth Bass

Why Are the Bass Sitting in 20–30 Feet Right Now?

The lake is down 25 feet, and that drop is pushing fish off the shallower structure they'd normally occupy this time of year during the pre-spawn and post-spawn transition. Combine that with mid-week winds stirring up the water column and you've got bass that are cautious, suspended, or hugging deeper structure — particularly between 20 and 30 feet. The good news? Finesse rigs are absolutely getting them.

Jim's go-to this week has been simple but very effective:

🎯 Rig #1: The Drop Shot — Jim's Top Producer This Week

The drop shot is the undisputed king at Castaic right now. Jim leaned hard on C3 Baits Shimmy's in two colors all week:

Neptune Shad — a translucent, shad-matching pattern that's perfect in that 10–20 ft clarity
Watermelon Candy — a classic California finesse color that bass just can't resist

How to fish it this week:

Set your drop shot weight 12–18 inches below your hook to keep the bait above the bottom where fish are suspending
Use a light spinning setup — 6–8 lb fluorocarbon is ideal for this water clarity
Work the bait with subtle shakes and dead sticks; don't overwork it
Focus on main lake points, submerged structure, and the deeper edges of the ski arm walls
Let the bait sit — in cold or pressured conditions, the pause is everything

For drop shot hooks, you'll want something with a thin wire for the best hookup ratio on those subtle bites. Our Gamakatsu Split Shot / Drop Shot Hooks are exactly what Jim's using on the Shimmy's — thin wire, laser-sharp, and built for finesse presentations. If you're fishing heavier cover or want a weedless option, step up to the Gamakatsu Weedless Split Shot / Drop Shot Hooks.

💡 Pro Tip from Jim: In 10–20 ft of visibility, go light on your fluorocarbon leader. The fish can see your line. Maxima Fluorocarbon or P-Line Halo Mist Green Fluorocarbon are both excellent low-vis choices.

🎯 Rig #2: Carolina Rig — Covering Water in the Wind

When the wind picks up and you need to cover more ground to find schools, the Carolina rig with C3 Baits Shimmy's(same Neptune Shad and Watermelon Candy colors) is the move. The C-rig lets you drag slowly through 20–30 ft depths, giving that Shimmy a natural, buoyant flutter right in the fish's face.

Carolina Rig Setup for Castaic:

3/4 oz to 1 oz ball weight (heavier = more bottom contact in wind)
18–24 inch fluorocarbon leader
Size 1 or 1/0 offset worm hook
Slow, deliberate drags along hard bottom transitions

Pick up Round Ball Weights in your Carolina rig kit — they thread cleanly on your main line and roll naturally over rocky bottom.

🎯 Rig #3: Wacky Rig — The Big-Fish Finisher

Three soft plastics are producing on wacky rigs right now, and all three are worth having in your box:

Daiwa Neko Fat 5" Worms — a thicker profile worm with that signature side-to-side wobble that bigger fish love
C3 Baits Calligators (Bait Merchant design) — a unique paddle-tail worm that performs incredibly well wacky style
C3 Baits Prototype 1 Worms — Jim's been testing these and they're producing; keep an eye on this bait

For wacky rigging, you need a hook that's specifically built for it — otherwise you'll be tearing through worms and missing fish. The Gamakatsu Wicked Wacky Hook is our top seller for this exact application, and the Owner Wacky Hook in Camo Green is a stealth option that blends into vegetation beautifully.

Where to target wacky rigs this week:

Shallower structure (8–15 ft) during warmer afternoon windows
Any remaining shaded areas along rock walls
The upper ski arm, where a few rainbow trout holdovers are also drawing bass into those zones

The One Moving Bait That's Working (When Conditions Line Up)

Here's Jim's inside tip of the week — and it requires a bit of patience and timing:

The MegaBass Vision 110 jerkbait fished along the West walls of the ski arm is producing some quality fish, but onlyduring warm, windy afternoons. The chop and warmer temps late in the day push fish up briefly, and that's your window. Burn it, pause it, and hold on.

"Thanks Blair" — Jim's shoutout to a local angler who dialed in this bite. That's the beauty of the Castaic community.

This is a reminder that moving and reaction baits haven't totally shut down — they're just conditional right now. Don't leave the dock without at least one jerkbait tied on as a backup.

Striped Bass Update: A Game of Patience

Striper fishing at Castaic is still a guessing game this week. The schools remain scattered and spread out, making it tough to target them consistently. But here's the encouraging news: the shad are getting shallower. As the forage moves up, the stripers will follow, and when that happens, most conventional techniques — trolling, jigging, live bait — will come into play.

What to watch for: Once surface temps push consistently into the upper 60s and the shad are visibly schooled in 10 feet or less, it's game on. Keep checking back for Jim's weekly report.

For when the striper bite opens up, a trolling jig like the SPRO Prime Bucktail Jig in White or Chartreuse is a proven reservoir striper producer. Stock up now before the bite fires.

Rainbow Trout: Season's Done, But They're Still Helping You Catch Bass

Stocking is officially over for the 2025–26 season at Castaic. However, holdover trout are still being caught — mostly by bass anglers throwing finesse and wacky worms in the upper end of the ski arm. This isn't a targeted trout fishery at this point, but it's a good reminder: those trout holdovers are concentrating baitfish in that zone, which in turn is holding bass. Work the upper ski arm with your drop shot or wacky rig and you might be surprised.

What To Pack for Your Castaic Trip This Weekend

Here's a quick gear checklist based on this week's report:

Terminal Tackle:

✅ Gamakatsu Split Shot / Drop Shot Hooks (sizes 1 and 2)
✅ Gamakatsu Wicked Wacky Hooks (size 1)
✅ Owner Down Shot Offset Hooks for heavier drop shot setups
✅ Round Ball Weights in 3/4 oz and 1 oz for Carolina rig
✅ Maxima Fluorocarbon Line — 6 lb and 8 lb for leaders

Soft Plastics to Source:

C3 Baits Shimmy's in Neptune Shad and Watermelon Candy
Daiwa Neko Fat 5" Worms
C3 Baits Calligators and Prototype 1 Worms

Hard Baits to Carry:

MegaBass Vision 110 jerkbait (West ski arm walls, afternoon only)
SPRO Prime Bucktail Jig in White (for when stripers turn on)

5 Key Takeaways for This Weekend

Fish deep (20–30 ft). The lake level drop has bass backed off shallow structure.
Drop shot is your primary weapon. C3 Baits Shimmy's in Neptune Shad or Watermelon Candy on a light spinning setup.
Carolina rig to cover ground. Use it when you need to search for scattered fish in the wind.
Wacky rig for bigger bites. Daiwa Neko Fat or C3 Calligators on Gamakatsu Wicked Wacky Hooks.
Be patient with moving baits. The Vision 110 window is real — but it requires warm, windy afternoons on the ski arm walls.
