Fly Fishing for Smallmouth Bass
Casting a weighted line that carries a nearly weightless artificial fly to the fish. Applied to smallmouth bass, that means 6–12 lb main line and a medium-light to medium, fast action rod as your baseline.

How the rig works
Unlike all other methods, the line provides the casting weight. That lets you present tiny imitations of insects delicately, and drift them at the same speed as the current so they look natural.
Smallmouth Bass behaviour
Crayfish, gobies and small baitfish. Feeds hard in current seams and around rock.
Cool, clear lakes and rocky rivers with current. Prefers gravel, boulder and rock flats over weed.
When to fish it
Clear water, 55–75°F (13–24°C), moving water or wind-blown rock banks.
Smallmouth Bass tips
- Match crayfish and goby colours — browns, greens and translucent patterns.
- Lighter line gets more bites in clear water; a fluorocarbon leader helps disguise braid.
- Fish current breaks: the slack pocket behind a boulder holds fish.
