Jig (Casting & Pitching) Fishing on St. Lawrence River
St. Lawrence River · New York · Northeast
The St. Lawrence River stretches along the New York–Ontario border, a massive, current-driven system running through the heart of the Thousand Islands region. Rocky points, submerged shoals, weed flats, and deep channel edges create an incredibly varied structural canvas that supports world-class smallmouth populations alongside largemouth, northern pike, muskellunge, and walleye. Water clarity skews clear to moderately clear, which means finesse presentations and natural color palettes tend to outperform loud, opaque offerings across much of the season.
A lead or tungsten head with a weed guard, skirt, and soft plastic trailer. Fished on the bottom by pitching, casting, or slow-rolling. The jig imitates crawfish and bottom-dwelling forage. More big bass have been caught on jigs than any other lure category — it's the lure that separates serious anglers.

Seasonal Tactics on St. Lawrence River
Lake: Smallmouth stage on shallow rocky shoals and sand flats in 4–10 ft as water temperatures climb through the low 50s into the low 60s; pre-spawn fish are aggressive on tube jigs and suspending jerkbaits worked near current breaks adjacent to deeper wintering areas.
Jig (Casting & Pitching): Pre-spawn is prime season — pitch brown/green pumpkin jig to 45° bank transitions and rocky points.
Lake: Post-spawn fish slide to main-river rocky points, mid-river shoals, and current seams in 12–22 ft, where gobies and crayfish dominate the forage; drop shots and football jigs worked slowly across hard-bottom structure are the workhorses once temperatures push into the upper 60s and 70s.
Jig (Casting & Pitching): Football jig on offshore ledges 15–30 feet. Swimming jig around grass edges at dawn.
Lake: Cooling water triggers aggressive topwater and swimbait action as smallmouth chase shad and shiners along weed edges and channel swings; October fishing can produce the year's biggest individual fish before the river shuts down.
Jig (Casting & Pitching): Swim a jig around baitfish schools near points and flats. Shad trailer colors in fall.
Lake: The St. Lawrence sees very limited open-water fishing in winter; ice-up typically covers large sections of the river by January, and access is restricted — late-season anglers targeting the final open-water weeks in late November focus on deep channel edges in 25–35 ft with blade baits and drop shots.
Jig (Casting & Pitching): Slowest presentation — drag a 3/8 oz football jig on deep hard bottom. Barely move it.
Best Conditions
All seasons, all depths, all cover types; most effective in 50–70°F water; excellent in pre-spawn and when fish are on hard bottom
Match trailer to conditions: craw trailer in cold water (slower fall, bigger profile), swimbait trailer when swimming, chunk trailer for flipping.
