Also known as Smallie, Bronzeback, Brown Bass, Smallmouth, Bronze Bomber. Bait, technique, tide windows, and where the bite is on right now.
Smallmouth bass cannot tolerate water above 27°C — they vacate shallow water through midsummer and stack up at the bottom of 8–12 m thermoclines in lakes, where current and oxygenation balance. The classic smallmouth gobi-fly under a strike indicator drifted on a long-line in 4 m current seam catches more fish than any topwater pattern in July and August.

River smallies (Susquehanna, Potomac, James, Shenandoah, French Broad, New River): wade or kayak-fish current seams, eddy lines, and behind midstream boulders. Cast Ned rigs and tube jigs up-current and let them tumble through pockets — most strikes come on the drop. Great Lakes smallies (Lake Erie Bass Islands, Lake St Clair, Sturgeon Bay WI, Mille Lacs MN): drop-shot deep rock structure in 15–35 ft, or run a Ned rig on transition zones. Pre-spawn and post-spawn jerkbait bite at the Erie ports (Geneva, Ashtabula) in May is one of the great smallie experiences in America. Northern lakes (Lake Champlain, Lake of the Woods, Rainy Lake): topwater dawn over rocky points + flats in summer. Smallmouth fight 2x harder than largemouth of equivalent size — light tackle and respect the fight.
Pre-spawn (water 50–58°F, April–May north / March southern range) is the textbook trophy window — smallies stage on rocky points and gravel near spawning flats and crush jerkbaits. Spawn (58–66°F) puts fish on beds in 4–10 ft of clear rocky water. Post-spawn (mid-summer): they push to current breaks in rivers or to deep rock humps and weed edges in lakes (15–25 ft on Erie). Fall (60°F dropping to 50°F): the trophy fall bite returns as fish feed heavily before winter — Lake Erie produces 5 lb+ smallmouth regularly in October–November on jigs and blade baits. Dawn and dusk produce best in summer; overcast windy days fish actively all day.
Smallmouth are weakly moon-influenced compared to largemouth. River flow and water clarity dominate — a falling clearing river 24–48 hours after a rain bump is the textbook river-smallie trigger. On Great Lakes, wind direction matters more than moon phase (a 2-day west wind on Lake Erie clears the water and stacks fish on structure). Spring and fall solunar majors at dawn correlate with active feeding windows.
Highly variable. New York (Lake Erie, St Lawrence): 12" minimum, bag of 5, season typically third Saturday June through November 30 with C&R-only season Dec 1 – mid-June (verify NYS DEC). Wisconsin / Minnesota / Michigan: 14" minimum, 5 fish, similar seasonal closures during spawn. Pennsylvania: 12" minimum, bag of 6 most waters with C&R-only sections on the Susquehanna in some years (recovering river). Always verify state DEC / DNR. Smallmouth culture is heavily C&R — most river anglers release everything, and the trophy 5 lb+ fish are statistically 10+ years old and should be photographed and released for the breeding pool.
