Start with Griffith's Gnat (18-22) on a As per local method. Early in the day, try buzzers on a slow figure-of-eight or a booby on a fast-sink line near the bottom. Rainbows respond to more active retrieves — try short strips between pauses.
A fry-imitating pattern stripped through the margins can save a blank in autumn.
Keep an eye on changing conditions — wind shifts and cloud breaks can trigger short feeding spells.
Good ripple suits both bank and boat. Bank: work inflows, dam walls, and points. Boat: broadside drift covering wind lanes.
