Smallmouth Buffalo FAQ

Answers from onWater's species guide.

What are the best lures and bait for Smallmouth Buffalo in Oklahoma?

Nightcrawlers, doughballs, corn, cut bait, or creep pellets (livestock feed secured with colored rubber bands).

What flies work for Smallmouth Buffalo in Oklahoma?

Carp crack patterns, woolly buggers, glo bugs, marabou jigs (1/100 oz), or small stonefly nymph imitations in olive/brown colors for clear water or bright pink/orange/chartreuse for stained water.

When is the best time to fish for Smallmouth Buffalo in Oklahoma?

Peak feeding periods in spring (March-April) and fall (October-December). Cooler months typically yield larger food volumes in their stomachs. Spawning occurs in late spring to early summer when water temperatures reach 62-65°F - avoid targeting fish during this reproductive period.

How do you catch Smallmouth Buffalo in Oklahoma?

Bottom fishing techniques work best - employ Carolina rigs with small hooks well-concealed in bait, as buffalo investigate baits cautiously before taking them. For fly fishing, present flies on or near the bottom with minimal movement - sometimes just a slight wiggle triggers takes.

What do Smallmouth Buffalo eat?

Smallmouth Buffalo are primarily detritivores and bottom feeders, consuming organic detritus (65%+ of diet), copepods, cladocera, chironomids, ostracods, algae, insect larvae, mollusk larvae, and small crustaceans.
