TUESDAY, OCTOBER 13, 2026 · ST. LAWRENCE RIVER
Cool water and falling pressure set up a day of goby hunting on deep gravel and current breaks before a front rolls in.
WATER 56°FAIR 49°FWIND 9 MPH ENECLARITY GIN-CLEAR NORTHERN WATER — 8-15+ FT VISIBILITY; SMALLMOUTH SIGHT-FISHING TERRITORYSEASON FALL
Water's in that 56-degree window where largemouth are transitioning off summer hangouts and grouping up on deeper structure ahead of winter. Clarity's exceptional, so sight-fishing and picking apart boulder fields works if you're shallow, but the real bite is on deep shoals and gravel flats where gobies are concentrated. Falling pressure before the weather rolls in will fire them up some, but the cloud cover and wind today keep the light soft. Fish will stay keyed on bottom structure and current, not chasing. This is a drop-shot and jigging day, not a topwater day.
The day's game plan
EARLY MORNING · 7:15 AM to 9:00 AM
Deep gravel flats and shoals in 25 to 35 feet around the main channel breaks and current seams where gobies stack in fall.
Drop-shot minnow in smoke or electric shad profile, 1/4 to 3/8 ounce weight, 12 to 18 inch leader. Keep the bait ticking bottom and let the current drift you. Work the shoal slowly, feel for boulders and transitions.
First light and the falling pressure have them feeding hard on bottom. In this clear water at this depth they're keyed on small forage. The drift covers water efficiently and keeps you in contact with the structure where they're holding.
MORNING · 9:00 AM to 11:30 AM
Transition zones between shallow sand and deep gravel, 15 to 25 feet. Look for boulder fields and rocky points where structure rises into current.
Compact finesse jig, 3/16 to 1/4 ounce, with a goby-colored soft plastic trailer, either crawdad or minnow profile. Drag slowly, pause on the harder spots, let it settle in the rocks.
Sun's still low even under clouds, and they'll slide up slightly into intermediate water as the morning push peaks. The jig lets you pick apart individual boulder piles and feel what's underneath. Smaller profile matches the fall forage without chasing.
MIDDAY · 11:30 AM to 2:00 PM
Deeper shoals and gravel flats, back to 28 to 40 feet, especially current-swept edges where the channel bends and water accelerates.
Half Shell or flat-profile drop-shot minnow, 3/8 to 1/2 ounce weight, longer 18 to 24 inch leader. Drift the current and cover ground. Switch to a tube, 3 to 4 inches, on a light jighead if you want more vibration.
Light's strongest midday even under full cloud, so fish pull deeper to stay comfortable. Current is your friend now. Lots of fish school hard on these deep gravel zones in October, so one productive drift can stack multiple fish. Electronics matter more than casting accuracy.
LATE AFTERNOON · 2:00 PM to 4:15 PM
Shallow boulder piles and sand-grass edges, 8 to 15 feet, particularly around isolated structure where prey is visible in clear water.
Light jighead with a shad-profile soft plastic, 1/8 to 1/4 ounce, or a small swimbait, 2 to 3 inches. Make short casts and pick apart the cover methodically. Work straight edges where shallow sand meets deeper rock.
Afternoon light softens under the clouds, and a secondary shallow bite develops as fish make feeding runs before evening. In gin-clear water they can see forage from a distance, so they'll chase a little. This is your best chance at topside action if you pick the right edges.
EVENING · 4:15 PM to 5:45 PM
Deep channel breaks and current seams, 25 to 35 feet. Return to the drifting zones from midday.
Drop-shot minnow, 1/4 to 3/8 ounce, in natural or slightly darker colors like smoke or watermelon. Slow drift, work the bottom.
As light drops and water temps are cool, they tighten up back to structure. The solunar minor at 7:30 PM is coming, and feeding pressure rises before dark. You want to be positioned on deep forage-rich structure as the evening bite turns on.
DUSK · 5:45 PM to 6:45 PM
Main channel ledges and the deepest accessible structure, 30 to 45 feet, especially near the dam discharge or any current acceleration point.
Tube bait, 3 to 4 inches, on a 1/4 to 3/8 ounce jighead. Drop vertically if current is strong, or short cast uptide and work back to the boat. Darker colors like junebug or black hold contrast in fading light.
Final push before dark. Temperature and reduced light push fish to tighter, deeper holding. Falling pressure and the solunar minor converge on the clock. Current-swept deep structure concentrates fish and forage. This window is often the best bite of the day when conditions are right.
NIGHT · 6:45 PM onward
Deep structure holds. If you stay out, anchor on a deep boulder field or current break and work it vertically or with slow drifts.
Heavier tube, 1/2 ounce jighead, or a dark blade bait on a short leader above a 1/2 ounce drop-shot weight. Vibration matters more in darkness. Keep presentations compact.
Cool water and dark skies mean forage-dense bottom structure. Fish don't move far after dark in fall. If you're staying, work the same deep shoals that held fish at dusk. Boat control and vertical presentations are your edge in darkness.
Where to fish
- Deep Gravel Shoals and Current Breaks — 25 to 40 ft · Gravel flats, boulder fields, shell and hard bottom swept by current. Focus on edges where the channel bends and water accelerates.
Fall gobies pile up on deep, current-swept, forage-rich bottom. Largemouth school hard here in October before they compress even deeper for winter. This is where tournament winners and local sticks find multiple fish on single drifts. - Thousand Islands Boulder Fields — 15 to 25 ft · Mixed rock, boulders, sand-grass transitions, isolated larger rocks rising from softer bottom. Named features like Carleton Island, Round Island, Grass Point, Bartlett Point, Chippewa Point.
Sight-fishing clarity lets you see structure and forage. Largemouth relate to boulders and edges as daytime staging zones between deep water and the flats. Morning and late afternoon shallow pushes funnel fish through these transitions. - Channel Ledges and Steep Edges — 28 to 45 ft · Vertical or near-vertical drop-offs where the river channel walls down. Hard bottom, current acceleration zones, proximity to deep water.
Prime holding for cooler-water fish. Depth and structure offer quick access to refuge. Forage concentrates on ledges and edges. Most reliable deep-water structure for concentrated schools in fall and early winter.
What to throw
- Drop-Shot Minnow — 2 to 2.5 in · Electric Shad, Smoke, Natural · 1/4 to 3/8 oz (All day on deep shoals and gravel. Peak at first light and dusk.)
Rig on a small finesse hook 12 to 24 inches above the weight. Let current carry the boat and keep the bait ticking bottom. Pause and twitch on structure. - Compact Finesse Jig with Soft Plastic Trailer — 1/4 to 3/8 in jighead, 2 to 3 in trailer · Black, Junebug, Crawdad Brown, Smoke · 1/4 oz or 3/16 oz (Morning into midday on intermediate to shallow structure. Best when working defined boulder piles.)
Cast to boulder fields and rocky structure. Drag slowly along bottom, pause on harder spots, let it settle into gaps. - Tube Bait — 3 to 4 in · Junebug, Black, Smoke, Watermelon Red Flake · 1/4 to 1/2 oz jighead (Midday deep drifts and evening to dusk when fish are tightest to structure.)
Rig on a 1/4 to 1/2 ounce jighead depending on depth and current. Fish vertical in strong current or short cast and hop back. Keep contact with bottom. - Small Swimbait — 2 to 3 in · Shad, Natural Forage · 1/8 to 1/4 oz jighead (Late afternoon into early evening when shallow feeding window opens.)
Cast to boulder edges and sand-grass transitions. Work with a steady retrieve or slow roll. Make short casts and pick apart the edges.
How to work it
- Drift Fishing Deep Shoals — Midday into dusk when fish are deep. Peak effectiveness during falling pressure and when current is steady. · Main channel breaks, current seams, boulder-strewn deep flats, especially around the Thousand Islands shoals and any point where structure meets flowing water.
Motor uptide of a known gravel or boulder shoal in 25 to 40 feet. Cut the motor and let current carry the boat. Fish a drop shot or tube vertically or with short casts downtide. Feel for bottom contact and structure. Mark fish on electronics and make repeat passes through the zone. - Vertical Jigging Near Structure — Morning when fish are in intermediate zones, and dusk when they compress onto deep structure as light fades. · Steep drop-offs, channel ledges, individual boulder piles, any vertical feature in 20 to 45 feet.
Position the boat uptide of a boulder field or ledge. Drop a compact jig or tube straight down. Work it with small hops and pauses. Hold bottom contact and feel for takes. - Picking Apart Shallow Rock and Edges — Late afternoon into early evening when light softens and a secondary shallow bite develops. Best on calm or lightly wind-affected spots where sight-fishing is possible. · Shallow intermediate water, 8 to 18 feet, around Carleton Island, Round Island, Grass Point, and anywhere large rocks rise into view in clear water.
Make precise short casts to individual boulders, rock shelves, sand-grass transitions, and isolated pieces of hard cover. Work methodically along the edges. Use light jigs or swimbaits. Pick apart the cover rather than making long sweeps.
Pro tips
- Electronics are your MVP today. Water's clear enough to spot structure and current seams visually from the surface, but you'll find more fish and pick apart deeper structure faster with a good sonar. Mark the gravel pockets and boulder clusters where fish stack on the shoals.
- The solunar minors at 10:48 AM and 7:30 PM are your tiebreakers. If you're already positioned right and fishing right technique, fish the minors. If conditions feel slow, don't waste time waiting for a solunar window to fix a bad location.
- As water cools through this transition, goby-colored finesse baits outperform anything else. Match the profile and color of the actual forage on the shoals. Keep your drop-shot leader long enough (18 to 24 inches) to let the bait swim above the junk, but short enough to stay in the strike zone when fish are lazy.
If conditions change
If the front blows through harder or colder than expected and the water temps drop another degree or two, pull even deeper and go smaller. Tighten your drop-shot leader to 12 to 15 inches and slow your drift speed to near-nothing. If the pressure stays falling longer than forecast and the wind eases, work the intermediate shoals longer into the afternoon. If clouds break and sun punches through, go deeper faster than the plan suggests and focus on shaded boulder fields and channel cuts where light doesn't penetrate as far. If the river gets a color shift from run-off or algae, swap to darker, more vibrant trailer colors like junebug or chart-and-black combos, and tighten your Ned rig and drop-shot leader so contrast is stronger.
