Water's at 67 degrees, right in the sweet spot for October on the Delta. Bass are grouping tighter toward slough mouths and pulling back from the deepest grass as the season shifts. Clarity is tidal and turbid, so reaction baits and vibration work best. Rising pressure after last night keeps things stable. If the clouds stay heavy, the shallow grass bite can hold all morning. Under bright sun or if it breaks clear, fish will slide deeper to the grassline edges and holes between the shallow cover. The solunar major at midday is a good secondary target window, but sunrise and the morning bite are your bread and butter right now.
The day's game plan
EARLY MORNING · 7:09 AM to 9:00 AM
Frank's Tract, Big Break and Little Mandeville shallow grass edges and tule pockets, 3 to 6 feet deep.
Green-pumpkin or black-and-blue 5-inch Senko rigged Texas weedless, 3/16 oz weight. Drag it slowly along grass clumps and work the open pockets between shallow cover. Cast tight to the edges, feel for the soft bite.
Water's still cool enough that fish are willing to hunt shallow, and the cloud cover this morning keeps them confident in the shallows. Tidal clarity is murky so they'll key on vibration and silhouette over color. Early light favors the finesse bite and edge-fishing before the sun climbs.
MORNING · 9:00 AM to 12:00 PM
Slough mouths in the south Delta: Old River, Middle River, Victoria Canal. Work transitions from 6 to 12 feet where grass meets deeper water.
1/2-oz white or chartreuse double-Colorado-blade spinnerbait with a 4-inch swimbait trailer, or a white-and-chartreuse Jackhammer ChatterBait, 3/8 oz. Work it with steady medium-speed burns along the grassline, lifting and dropping at the transition points.
As the sun climbs, bass slide from pure shallow to the edges. A reaction bait covers water fast and triggers strikes from scattered fish. Turbid water favors the thump and vibration of a double blade over finesse. The trailer gives a visual cue that turbid-water bass can lock onto.
MIDDAY · 12:00 PM to 3:00 PM
Deeper holes and transitions within Frank's Tract, Big Break. Work 10 to 15 feet on submerged grassline edges and small depressions where bass stage between slough mouths.
Green-pumpkin Senko on a weighted wacky rig, 3/16 oz. Drop it vertically into the holes, shake it in place for 3 to 5 seconds, then slowly lift and repeat. Or work a green-pumpkin drop-shot, 1/4 oz weight, 18 inches above a small finesse jig head.
Midday sun pushes bass down from the absolute shallows. Deeper transitions with cover are where they stack to stay comfortable. The solunar major at 12:14 PM can add to the bite if you're in the right zone. Finesse works because they're not chasing, just resting and feeding selectively on smaller profiles.
LATE AFTERNOON · 3:00 PM to 5:00 PM
Back to slough mouths and secondary points near the main-river channel access. Work 8 to 14 feet on the channel-break edges where bait stages.
A 5-inch swimbait rigged on a weighted swimbait hook, 1/4 oz, or a swim jig with a shad-profile trailer, 3/8 oz. Cast and retrieve with a steady, moderate pace, letting the bait work the edge of the channel transition.
As afternoon light softens, bass begin staging back shallow toward the slough mouths where they'll feed harder into evening. The transition zone holds both foraging fish and rest-holding fish, so covering it efficiently bridges the gap between midday dormancy and the evening bite.
EVENING · 5:00 PM to 6:30 PM
Shallow grass pockets and riprap banks inside the sloughs and around Frank's Tract. Work 3 to 8 feet.
A 5-inch black-and-blue or watermelon-red-flake worm rigged Texas, 1/4 oz. Cast it around tule clumps, under any overhanging cover, and along riprap. Drag it slowly, pause on every piece of structure.
As light fades, bass move back to the shallowest, thickest cover to hunt. The minor solunar at 6:05 PM can align with this bite. Tidal clarity is still murky, so dark colors create strong silhouettes against the fading light. They're feeding more aggressively as the day winds down.
DUSK · 6:30 PM to 7:15 PM
Shallow mats, tule edges and open pockets in Frank's Tract and Big Break. 2 to 6 feet.
A hollow-body frog or a 3.5-inch walking bait, fished across shallow mats and open water. Cast and work with steady twitches, keeping the action on top or just below the surface.
Low-light topwater and frogs draw reaction strikes from bass that are actively hunting. Even if the punch bite is off, a frog over matted cover will produce. Topwater and hollow-body patterns shine in the last 45 minutes of usable light.
NIGHT · After 7:15 PM
Deeper holes, channel edges, and grassline transitions 12 to 20 feet deep where bass retreat to rest water with better oxygen flow.
If you're night fishing, work a 5-inch green-pumpkin Senko on a weighted wacky rig, 3/16 oz, or a drop-shot, fished slowly and deliberately in the deepest available grassline transition. Most night fishing on the Delta targets finesse around known structure.
Bass pull away from shallow cover after dark. They stack on deeper edges and open water adjacent to structure where they can rest and sense prey movement. Night finesse is a specialty pattern, not a primary day-long strategy.
Where to fish
- Frank's Tract — 3 to 15 feet depending on zone · Shallow tule and grass pockets grading to deeper grassline edges and central holes. Transitions between mat cover and open water.
Frank's Tract is a fall staging area as bass group tighter with cooling water. Shallow pockets hold biters early and at dusk. Deeper edges mid-day. It's accessible across the tidal range and holds bait consistently. - Big Break and Little Mandeville — 2 to 12 feet · Shallow flats with tule and grass cover near slough mouths. Transitions to deeper grassline edges. Marina and dock structure nearby.
These dead-end sloughs funnel bass as they concentrate during fall transition. Shallow cover holds aggressive early-morning and evening biters. Grassline edges just outside the sloughs hold mid-day rest fish. - Old River, Middle River and Victoria Canal Slough Mouths — 6 to 20 feet · Channel-edge transitions, submerged grassline, riprap banks near slough entrances.
Slough mouths are the staging ground where bass group on their way between shallow feeding and deep rest zones. Channel breaks hold forage and make for efficient searching during mid-morning through late afternoon.
What to throw
- 5-inch Senko — 5 in · Green Pumpkin or Black-and-Blue · 3/16 oz (weighted wacky or Texas rig) (Early morning, midday deep transitions, evening shallow cover.)
Drag along grass edges and through shallow pockets. Pause on cover. On deeper drop-shot, shake vertically. - Double-Colorado Spinnerbait or Jackhammer ChatterBait — 3.5 to 5 in · White or White-and-Chartreuse · 3/8 to 1/2 oz (Morning to early afternoon on grassline edges.)
Steady medium-speed burn along grassline edges and channel transitions. Lift and drop at depth changes to trigger strikes. - Swimbait or Swim Jig — 4 to 5 in · Natural Shad or Green Pumpkin · 1/4 to 3/8 oz (Late afternoon through evening when bass stage back toward slough mouths.)
Cast to structure and burn with steady retrieves along edges and transitions. Work it with slight pauses and lifts over deeper holes. - Hollow-Body Frog — 3.5 in · Natural or Chartreuse · n/a (Dusk and low-light hours over matted vegetation.)
Cast over mats and open pockets. Work with steady twitches and walks. Keep it on top or skating just below surface. - Drop-Shot Rig — 3 to 4 in finesse bait · Green Pumpkin or PB&J · 1/4 to 3/8 oz weight (Midday deep transitions and when pressure fades post-front.)
Drop vertically or cast and work with micro-hops and shakes. Hold bottom and shake for 3 to 5 seconds, then lift slowly.
How to work it
- Edge Fishing — Morning through late afternoon when bass stage between shallow and deep. · Grassline transitions, slough mouths, main-channel edges.
Cast along the transition where shallow grass meets deeper water or open holes. Work the bait slowly in the seam, pausing at the edge. - Reaction Burn — Morning and early afternoon when sunlight is still moderate and turbidity favors vibration. · Grassline edges, channel breaks, riprap banks.
Cast a vibrating jig, spinnerbait or ChatterBait and burn it at steady medium speed along structure edges. Lift and drop when you hit transitions to trigger reflex strikes. - Topwater and Frog Work — Dusk and low-light hours when reaction strikes peak. · Shallow mats, tule edges, open-water pockets in Frank's Tract and Big Break.
Cast a hollow-body frog or walking bait over mats and open pockets. Work with steady twitches and slight walks. Keep the action on surface or just under.
Pro tips
- Tidal clarity is your key today. If the tide is pushing water clarity lower (murkier), bump up blade vibration and go with darker colors. If it's clearing, scale down to finesse and natural colors. Don't be afraid to run the same area twice as the tide cycle changes.
- Pressure is rising, which keeps bass stable and willing. Don't over-complicate your pattern. Dial in one bait and one depth on the first fish you catch, then replicate that setup across similar structure. Early fall is about repeatable patterns, not searching for a miracle.
- If the sun breaks through hard by midday, pull deeper faster and lean on drop-shot and wacky-rig finesse. Don't waste time on shallow cover once the light gets bright and the pressure keeps rising. Deep transitions and grassline edges 12 to 15 feet deep will hold quality fish the rest of the day.
If conditions change
If a front rolls in and the pressure drops further, fire up reaction baits and cover water fast. Bass will bite harder into any incoming system. If the pressure rises sharply post-front and the sky clears, downsize everything, slow your retrieves way down, and fish tight to the thickest available cover. Tight squeeze in a mat or a pocket of tules will hold fish when post-front pressure is climbing. If the wind shifts to the south or southwest, the shallow bite holds longer as the water temperature stabilizes. North wind knocks the bite down, so don't waste too much time shallow if it freshens. If the water clears from this turbid state, natural colors and longer leaders matter more. Switch to a smoke or shad-pattern Senko and extend your fluorocarbon leader to 2 feet. If it muddies further, go blacker and louder. Black worms, dark chatterbaits, and Colorado blades dominate in real mud.
