Start with Marabou Damsel (8-12) — on the point. 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.
Fish early and late, try deeper during the heat of the day with a fast-sinking line.
Damsel Nymph may strengthen through the middle of the day as conditions warm.
Bank-only venue. Fish from accessible margins, points, weed edges, and inflows.
